  1. Hi there,

    I know that your request is already a bit older, but I have a "small" lathe that I might part of...

    (with a bleeding heart because I love it, certainly after all the mod's I added)

    It's a 9X20 lathe similar to the ones that are sold by Harbor Freight etc.

    (Made in China), thus it has it limits.

    Comes complete with stand and additional blocks under the stand to bring it up to "western"

    working height.

    However, I implemented about all the modifications that are available on the WWW to turn

    this lathe into a HQ machine, even added digital readouts to it (currently taken off)

    added a QCTP (self made on my mill) with a number of tool holders, and some other gadgets,

    replaced the head by a larger one (5" OR 6" not sure anymore), allowing me to deal with larger

    parts adding at the same time more stability.

    here a link to a manual @ Grizzly.com: http://cdn0.grizzly.com/manuals/g4000_m.pdf

    it's the described as a 9X19" but it's the same machine.

  2. For http://www.gamling.org/#_=_ here is a translation of what the symbols mean. I'm pretty sure this is right, but my reading of Thai isn't perfect, so someone correct me if I'm wrong. Also, feel free to save/repost this if needed.

    You can also use Google Chrome as browser... when opening Gamling, it will offer on-line translation.... also of the texts within the markers... translations are not top but understandable... and yes Gamling is very up to date with information from locals....

  3. even removing all occurrences of those files did not prevent it from re-installing...

    I then renamed the ntosboot...pf to something useless, removed the virus files once more

    and rebooted, now it did not re-create entries in the Prefetch.

    I also found a task in the "scheduled tasks" via the Spybot CD secure shredder.

    Killed that one and the related files.

    Seems to be clean... AVG could not be re-installed, some registry-key could not be accessed,

    after I fixed that, AVG is now installed and running a full scan, this completed, I will set it to

    go for a deep scan.

    WE will see....

  4. Hi residentgeek,

    I've been applying a similar approach yesterday, I have a cd-bootable XP (Spybot has the tools and guideline to create such with spybot on the CD)

    There is also a command window included, so that eases the access to the HDD.

    To find those files in the system32: dir /a:rsh *.* will show all hidden, dir /a:rsh *.exe only executables, dir /a:rsh w*.* & dir /a:rsh q*.* the

    nasties..

    del /a:rsh {filename} will remove them. (also delete QXVZ*.exe, that one is a visible copy of the virus)

    We are closing in on the beast, let's hope that it can be killed..... :)

    (I've been running some searches through the WWW, some PC's in Germany are hit also.)

    AVG does detect the virus and presumably removes it, but after rebooting it is back to square 1.

    no useful information is found on the websites of AV engines...

    If you have spybot installed, after removing the virus "remotely", in booting, Spybot's "teatimer" will pop-up with the Conime file ... deny change stops it.

    Three more computers to go, and then re-check the others on Monday...

  5. Indeed there is more to it,

    I cleaned two notebooks yesterday, tested them again this morning before bringing them back to the office, all clear.

    within 4 minutes running in the office one of the was re-infected.

    In the office there is a small fileserver (those small boxes) and on the public directory I found an autorun.inf of 500+ KB,

    and some hidden ~tmp??? directory.

    Deleted that stuff, and fixed that one NB again, and it seems to be working, the second NB was used after the file server fix and that

    remained clean.

    This thing is so new, practically no information is to be found, and the infection seems to differ.

    We do detect the QXZ...exe but there seems to be another mechanism that is re-planting it. Merely quarantining it does not solve the problem, and if it manages to start again, the AV and spybot are disabled, among other AV tools.

    So we are not at the end of it and it is spreading!!!

  6. A Fix,

    {at least it seems to work on both notebooks I repaired}

    !! you have to be in administrator rights !!

    After windows is fully loaded, open "windows\prefetch"

    find entries like "WCOREDT*.pf" and "QXVZ*.pf" and delete them

    then open layout.ini in the same directory, and find those entries but now with the real path

    "C:\WINDOWS\System32\...." and delete them in the .ini file (WCOREDT.exe will come first)

    then save this layout.ini as layout.txt

    rename the original layout.ini to layout.xxx, and afterward layout.txt to layout.ini.

    Goto C:\WINDOWS\System32\ and find QXVZ*.exe, rename the extension to anything except

    .exe, .dll, .com or so.

    Reboot the computer immediately after your change.

    After full reboot, got back to C:\WINDOWS\System32 and delete that renamed file.

    Remove and re-install your usual AV software (some intermediate re-booting might be required)

    Have the "new" AV do a full scan, it will probably find some entries in temporary internet file directory

    and also the "WCOREDT.EXE" file !!( stay with it, it is possible that this virus will even be detected before

    the scan starts and it will then be re-detected, as soon as it is detected (AVG pops-up a special window)

    delete it immediately.

    (You probably will have to reboot once more)

    By the fact that the files are now detected with an AV, an attempted re-infection will also be detected...

    it seems that his virus is also attaching or embedding itself in other programs..

    (I had two occurrences that triggered the virus-shield of AVG, and I'm still running tests...)

    Apparently there are no entries in the registry, at least not obvious ones, it all seems to be installed

    via the windows prefetch (but no guarantees on this statement, it is still to early to say for sure)

    All this as a temporary fix for this nasty beast. Anyway I now have two "properly" working notebooks again.

    Good Luck

    SM

  7. I have a question

    how to go safe mode?i seriously don't know this.

    when the computer boots, just after you see the bios information, press F5, then a selection screen should show up, the press F8, and you will then see the option to boot in Safe Mode.

    However if this is related to this virus problem, forget it, it also ends in a BSOD.

    SM...

  8. Follow up....

    The virus is according to "Prevx"

    • Cloaked Malware
    • Malware Dropper

    also known as "QXZV5.EXE" or WCOREDT.EXE or DSC-NEWPICTURE017.JPEG_WWW.CRAZYPHOTOHOST.COM.

    It places itself in system32 under one or both of the first two names, the later one is hidden, it also has reference links stored in the \WINDOWS\Prefetch and the there included .ini file. The WCOREDT is pretty early referred in the prefetch, long before any AV software is started.

    Prevx claims to have a removal tool (buyware), no other AV's mention much reference, AVG will not find it when the computer is already infected, and in due course, the virus will disable any AV software, additionally block access to any website that might have a solution.

    Spybot does not work either, trying to use Combofix ends in a BSOD.

    Scanning the drives is probably useless, I found it because I removed the HDD from the notebook and had it scanned as an external drive

    on a PC, then also AVG will recognize it.

    More to follow...

  9. I just got a phone call from one of my customers, two of his notebooks show the same symptoms, and the virus seems to do more than just sending out stuff, he informed me that his Avira was now deactivated and he could not get it running anymore.

    He also indicated that this afternoon the rest of his staff complained that their computers where sluggish... reason unknown, if the sluggishness was due to not being able to get onto the internet, then it could be understandable, this virus could be claiming all bandwidth on the ADSL, he had a similar one a few months ago that was constantly sending e-mails, but first tried to resolve the targets with a DNS resolution, thus jamming that track profoundly.

    Anyway, I'll have my fun tomorrow morning.... and hopefully find a cure, but I'll keep you posted on the progress

  10. I think that the current plastic bags are to a certain extend degradable.

    They do not live forever.

    I have always a few at hand in the corner where I clean our cats litter, thus outside but not in the sun, and if they are laying

    there to long, I can't use them anymore, they just rip to pieces.

    I can't pinpoint a time frame, but a bit over a month or so they lose their strength.

    Of course I'm also in favor of using textile bags, for two reasons... one is environmental, the other is shopping habits.. if you only carry a few textile bags and want to avoid the plastic ones, you will not buy more than you can carry.

    Specially useful in those supermarkets that use whatever trick to have you buy more than you need. And these days they really are doing an effort.

  11. I think we all are missing the point,

    I do not think that those "legally" working tourists are causing to much harm financially, or take all those jobs away from the Thais.

    (the statement we heard over and over in EU, but where it boiled down to was that those "foreigners" did the jobs locals didn't want,

    being to hard or to dirty or below the locals "educational" level)

    Looking down history of visa amendments, each change, specially for those who are long-stayers, resulted in bringing in more bucks into this country.

    Preventing those "back-to-back" tricks is one more down that lane, or you have enough money to get a decent visa or you are not worth to stay in this country, they don't want low-income people.

    Countries live from the business they do, import-export, tourism etc., others from offering incentives (for a price)...

    This country is mostly aiming at the later one, and will constantly amend the laws to get what they want, or produce the next

    nicely wrapped package to get more bucks into the country. This of course under the condition that little or no effort is involved

    to get to it.

    In the animal world there are some species that show the same behavior, however I forgot their classification.....

  12. Anyone ?

    Try Pornsak on Oh Nut rd.

    drive outbound om Sukumvit 77 to the new airport, where Oh Nut intersects with Udomsuk Rd. (traffic lights just before the outer ring road) make a u-turn, back on the inbound road, you will pass a large LPG/CNG station, shortly after you will see an u-turn, exactly across of that u-turn, on the left-hand side is the entrance to their shop.

    You can also search the WWW for pornsak lpg, they should pop up also, website is in Thai only.. staff speaks little English, except some of the secretaries in the front office.

    One general advice: formulate your questions correctly....:

    if you ask " can you install LPG in my car" the answer will be "yes"

    Should you ask " can my car [car specs.] run on LPG" you will get "let us check"

    after a positive answer you can then go into the details....

    Reason for this approach, I advised one of my friends to his LPG... and of course they could install it on his CRV, unfortunately, exactly his model with the mounted engine was not suitable to run LPG, after he started to run into trouble, I checked once more and found a warning letter from Honda Germany concerning the installation of LPG on certain engine types of Honda, his was on the list.

    So beware

    SM...

  13. Sorry to contradict some of the posters but cable quality does make the difference......

    And the statement "If a 1 is sent, then a 1 is received. It is not stronger nor weaker, it is simply 1."

    only holds partial truth.

    The correct statement would be: " if a "1" is sent and remains a "1" and in sync with the clock signal, then a 1 is received, otherwise it is anything"

    For the technical versed : http://en.wikipedia.org/wiki/High-Definiti...media_Interface

    There you can see the wiring layout of the connector thus also cable "content".

    The cable contains 4 shielded cable pairs ("Data-0", "Data-1", "Data-2" and "Clock") and a few loose ones.

    Each "pair" consists of a positive signal strand and a negative signal strand, around them a shield.

    When a "1" is send, the positive line will have Positive voltage compared to ground, the negative line will have a negative voltage compared to ground.

    At the receiving end both wires end up in a comparator, and if the positive signal does not match the negative signal, the "1" is discarded. (same when a "0" is send)

    At the receiving end, the level (1 or 0) at the comparator output is only processed when the clock "tick's"

    (same technology is used on CAT-5 Ethernet cables, however shielding is different)

    The four mayor groups all apply the same "signal quality" technique.

    and this with frequencies up to 340 Mhz.

    What each of those pairs is carrying is now irrelevant, key factor is that whatever data is transmitted has to remain in synchronization with the "Clock", and remain valid at the receiving end.

    "low-cost" cables might produce more signal drop-outs (differential signal at receiving side no longer valid) than so-called "high-end" cables.

    Factors like strand diameter, shielding quality, equal length, soldering/crimping quality are all factors that will reflect on the signal.

    - Diameter: is the core of a strand to thin, the inner resistance will slow down the transmission of the bit...

    - Shielding: is the weaving to coarse, stray signals from the other groups and or adjacent equipment may disturb the data stream,

    mostly by generating unbalanced differential signals in one or more groups

    -Eq. Length: even a few millimeters of difference in length of the inner wires can, with the applied frequencies, cause timing glitches.

    -Soldering: bad soldering or crimping will increase the inner resistance and (see diameter).

    An additional factor for the low-end cables is the QC and final test, since they want to keep the production costs low, testing will be at the utmost minimum, cables will be tested for their electrical quality (does each wire carry the signal over), but rarely for signal quality and timing.

    For mid to high-end cables, signal quality testing will be applied, those who "pass" barely are mid-range, and those who pass with flying colors are the very expensive high-end cables.

    So when you have to decide what cable to buy, low cost is a gamble, most mid range cables will do within a certain length, do you need long cables then probably only high-end will do a proper job. this assuming you only accept first class image quality.

    One thing, before I forget it.... all image/audio/control signals are transmitted serial, thus data for each pixel comes as a chain of 1&0's then these chains are cut in to proper length, stacked on top of each other, the same is done for the other data, and when all information for 1 pixel and audio for that moment in time and position on screen is received, it is put on screen and speaker(s).

    Think about that!!!

  14. I always go for the ticket, because I know they hate to write one, and they don't get as much out of it as the "tea-money".

    and ..... I tend to be at the collecting station next day at 8 in the morning.... until now that has always given me a reasonable satisfaction... day shift starts at 8 and mostly they (the copper who wrote the ticket) tend to be late..... only once my drivers license was there before me.

    The scenario is mostly the same:

    Present my ticket... officer goes through the licenses, does not find mine, checks the book, no entry yet....

    Stupid look, apologies, if I would be so kind to wait a few minutes....

    (can easily be half an hour or more)

    The station officer is clearly getting nervous

    Mostly the station commander start asking questions why that falang is sitting there.....

    Ticket writer comes to work (late)

    Get's a fat yelling from the commander

    more apologies.... also from the ticket writer

    Pay my fine (with pleasure, that little show was worth the money)

    Walk out with drivers license and a big grin on my face...

    (once they even waived the fine out of pure embarrassment)

    Before there is any misunderstanding, I do not get tickets often, but I'm already driving around here since 13 years.... so you do collect a few anyway.

    And out of personal experience, the copper that wrote you that ticket will never forget your face, and let you go the next time.

    (happened on Srinakarin Rd. next to Bang-na Trat, got a ticket for driving on the right lane with my motorbike, was at the station early next morning...., a few months later was stopped there again, for no apparent reason, same copper, when he recognized me, he only said "GO!!!!" in a not so friendly way)

  15. Both shut down the complete fuel system including the fuel pump in the tank.

    How can I check if it is shutdown in my car?

    LPG/gasoline switch is instantaneious and unnoticable.

    I can only tell you how to check it in a Zafira, for a 2.2 engine you will see an aluminum tube in front of the engine, that has what might look as a "refill" nipple on it (black screw-on cap over it). One might think that it is aircon related.

    This is your main fuel line to the injectors.

    Main purpose of this nipple is to verify fuel pressure while the pump is running.

    To see if the pump is switched off in LPG mode... remove the cap, take a cloth to wrap around the area to absorb possible gasoline spilling (you certainly do not want gasoline to drip/drop on your hot engine...)

    In case the pump is still on, and pushing down the nipple, gasoline will exit from there under pressure, otherwise only a few drops or nothing at all exits from there

    (just push it a little, the nipple isn't the best quality and might not seal properly after, when to much force is applied)

    After the test and verified that in Gasoline mode there is no fuel exiting from that nipple, recap firmly with the black plastic cap.

    There is no way that you would be able to hear the pump running, engine and exhaust noise will prevent that.

    Alternatively, if you know where the electrical wiring to the pump goes, test if 12 V is supplied to the pump, if yes, the pump is on.

    (if there is a connector, it might be easier to check, otherwise take a needle an stick it in the "hot" line to the pump, hold a voltage tester pin to the needle and the other one on a blank chassis or engine part the is guaranteed grounded)

  16. American media ignore Holden, Vauxhall, Opel, Daewoo, Isuzu; plants in China, Mexico, Thailand, etc.

    Quite normal... they are not US companies, and GM is also happy that not to much is revealed, someone might ask some unpleasant questions about the relationship with them.

    Based on the latest news from Germany, Their might be a buyer for Opel, Fiat already bailed out, Magna is the only one left, and seems to comply with the requirements of the German govt.

    However within the whole negotiations, GM is the one who is trying to prevent the buy out.

    One of the reasons that GM is trying to keep Opel is that contrary to common belief and the stories created around it, Opel is doing quite well, and their cars are selling good in EU, that they make successful cars is probably also proven by the number of Chevrolet Zafira's that are on TH roads (originally it is a Opel Zafira, and the Chev Zafi in TH is about 95% original Opel)

    What constantly puts Opel in the red is that GM keeps draining them financially, a known fact, and also one of the problems that the German govt. has with implementing any support program, they are afraid that the money they would put in Opel, goes to GM.

    As to the other mentioned brands... Vauxhall's are now mostly re branded Opels.

    Deawoo, Holden and Isuzu are financially and product wise at the bottom end of the GM spectrum. And GM wouldn't mind selling them, but nobody wants to buy....

    As to the future of Chev./GM TH, GM might disappear over time (even when they file for bankruptcy, it will take quite some time before it would really shut them down, effectively, they will file for "Chapter 11" what basically means "bankruptcy protection" so they can continue, be it supervised). Chevrolet will be here somewhat longer, maybe only as a service center (they do make good money in the maintenance to....) and with the stockpile in spare parts, there is little to worry.

    If it would be wise to by a Chev./GM "group" car? only the future will tell. the current advantage of the situation is the they go cheap on the second hand market.

    One commonly not so well known aspect of GM-Opel is that the R&D center of GM is with Opel Germany, they serve the whole GM group... when Opel spin's of, it will cause a major headache to split the R&D up, and what from that center will return to GM and what remains with Opel is one of the bigger problems. Keeping the whole center with Opel is not feasable, for one the costs, and secondly whatever has been and is designed there is property of GM, so GM could make a nice buck on the continued licensing fees on Opel car parts/cars...

    A probable scenario for the center could be that it fully goes to GM, and since GM is in no position the maintain the current status (personell and financially wise), they will have to lay off the majority of the staff... Opel starts their own R&D center and get's those people back, and they will certainly find a way around the old licenses...

    Within the whole GM group there are a few brands that are worth saving, not for the name sake, but those brands are profitable.

    GM itself deserves to die, they are merely a parasite that feeds on those brands. In the battle for Opel, it was revealed that Opel has to turn over all profits to GM every year, and money Opel needs is to be loaned from GM with not so atractive interest rates, I'm sure GM does this with all others as well. Not that this is illegal, its common practice within international corporations, but it distorts the reality.

  17. Looks like the cars that reached Stingray are all old, crude vacuum suction systems.

    These days most people opt for injector heads, precisely for reasons outlined in Stingray's post.

    The thing about fuel pump is interesting. I have never thought about it, but it makes a lot of sense. It costs nothing to drive with half a tank.

    Reason why I stumbled onto that article is because I ran into trouble with my fuel system....

    over the last months we where having more and more trouble starting the car in gasoline mode, up to the point that it wasn't possible anymore.

    So, first diagnose, cracked fuel line in the gasoline tank, the overpressure return valve apparently didn't work as required, and the fuel line cracked.

    The pump itself did also suffer, to the extend that after fixing problem 1, the technicians noticed that the fuel pressure at the injector rail was not sufficient anymore... new pump (8K thb).

    about 4 days after the new pump was in, suddenly no way to start anymore.... the new hose had slipped of in the gasoline tank...

    fixed.. until the day before yesterday, same problem again.

    So, conclusion, add an extra relay that will shut down the fuel pump while driving on Gas. That should do it.

    (from what I heard at Chev, I'm not the only one that suffers from a fuel circuit problem on LPG driven cars, specially with the type of fuel pump used.... seems not to be a problem with LPG driven Zafi's in Germany, probably they mount the extra relay immediately)

    (the extra relay is needed, just cutting of the main fuel pump relay will bring the Zafi to a full stop because it also powers the injectors)

    {by the way.. I suffer from some kind of "OCD", I do not buy a car if I can not have/find a copy of the shop manual... this does not mean that I will fix things myself, it helps when a mechanic tries to BS me.., or in this case to see the "booby trap" on the main fuel pump relay.}

  18. Eh... wasn't there a campaign by the Th government a few years ago where they propagated that Thai spouses married to Falangs could now buy and own land, be it from her own money.... but preferably from money "donated" to her by her Falang husband... whom to make it really interesting for the govt. had to bring that money from abroad.

    How does that fit in the current picture now, I'm rather confused....

    Or is this the habitual way of doing things in this country, get as many idiots pouring funds into the country, and then revoke their "rights", not that they have any on the "donated" money, but anyway.

  19. I'm in the used car business and all the used cars fittet with LPG Systems we bought had serious problems whenn we try to running them on Gasoline. Older cars with carburetors not a big deal. But all newer cars with injections, engine management systems, electric fuel pumps and sensors got problems. Mosthly fuel gauges and fuel pumps and sensors not work anymore, because locals drove on LPG for years without a drop of Benzine in the tank. Fuel pump and fuel gauge sensors getting corrosion and die. Today we i don't buy any cars with LPG coversation anymore. To much headaches in the past and another reason: We don't want to be responsabile if one of our customers would "blow up".

    I completely follow you there, irresponsible LPG car owners leave you with a wrecked system. Unfortunately, there are to many of them here.

    Running Gas only, will ruin your injectors, fuel pump and related.

    A few day's ago I came across an article in a UK forum on driving with an almost empty gasoline tank (and using LPG mostly).

    Apparently modern cars with electrical fuel pumps that are mounted in the gasoline tank should have at least half a tank of gasoline all the time (in almost constant LPG mode driving). Reason being that average LPG systems do not shut of the gasoline pump when running LPG.

    With little fuel around the pump, they tend to heat up and eventually fail. Half a tank provides enough "liquid" around the pump.

    Generally there is no problem with the running fuel pump, they have an overpressure valve that will return the fuel to the tank, and are designed for constant running. But running them constantly in an almost "dry" condition will kill them.

    And that's what you can get with a second hand car, also mostly the reason why they sold it.... there is some trouble ahead or already ran into it.

    These problems can be fixed, but do cost, and since the previous owner has demonstrated that he is really on "cost saving", he will not spend the money. Also a bit of a local attitude, buy it, use it until it breaks, get rid of it.

  20. Hello,

    my friend is installing lpg systems in cars - ESGI 2 - and he says his clients are relly satidfied with it. It really makes the costs go down. It is importanta, especially now, when the petrol prices are going up. If you have a chance to do it - go ahead. ESGI 2 systems are one of the best, as far as I know.

    I do not want to degrade the assumed quality of the product, but the company in Poland that (presumably) manufactures them is fairly new and only recently obtained TUV certification for their product.

    This compared to the currently popular LPG systems.

  21. When i have been following up second hand cars for sale, i find a lot have had LPG fitted in the past year. Anyone any experience of using it. is it any good, is the saving in running cost worth any potential problems with engine etc

    As mentioned by others "be aware".

    And.. stay away from Honda CRV's with LPG, they probably will have a ruined engine or will soon have.

    (or they have to prove that they have a new cylinder-head with hardened valve-seats and valves)

    Last year, a friend asked me if it would be possible to put LPG in his CRV, "Sure!!" I said...

    now I'm feeling very sorry that I gave him the green light.

    (he is still my friend, or the other way around, still considers me to be his friend...)

    Since his CRV was not that old, thus having an engine for un-leaded fuel, should no be a problem.

    (I should have investigated more....)

    Now that he has the problems, I did some more investigating in EU forums, and found out that indeed the second generation CRV engines are not happy with LPG. In EU there is even an official advisory from Honda on that matter, with the technical's what will go wrong over time... (nicely fitting his current symptoms)

    So beware, and do not trust the Gas installer's statement, they also gave him a green light, and now they tell him that indeed there might be problems related to LPG. (after the warranty is void)....

    Before I did my own car, I spend months investigating and questioning EU LPG users that drive a Zafira 2.2, after I had a 85% green light I did go for it (the other 15% where more installation than usage related).

    As I mentioned in a previous post, I was in to fix a "minor" problem, and one of their first statements was that it was the engine, there where know problems with Zafi engines...., "BS" I replied, there are thousands of Zafi's in EU that have been converted to LPG, and no engine problems what so ever, and ... the engines in TH Zafi's are the original Ecotec engines from Opel Germany, thus do not tell me it's the engine.

    Well it wasn't, the problem where the gas injectors, over time (less than a year), the little pistons inside jammed up, this due to the grease used, hardening out. After cleaning and re-greasing them all trouble was over.

    Hardening out is not an issue in EU climate... but here in TH, where it is a lot hotter under the hood than overthere.

    I know that above is OT, but worth sharing...

  22. I know this is not relating to the topic but could some one tell me how much a conversion for LPG or CNG cost and and how many years would it take to recover the installation and would it be worth doing this on a 10 year old car?

    You could browse/search through the forum with "lpg" as a keyword, there you will probably find all the answers.

    A conversion for LPG goes between 19K for a fix mixer and 30~40K for a seq. injection. CNG is around 60K.

    As the price difference between gasoline and LPG is less than a year ago, the recovery of your installation is taking a bit longer.

    To get an estimate, take your average gasoline consumption per 100KM, add about 30% to that number to come to the estimated LPG consumption (fully depending on the type of installation, fix mixers burn a bit more, seq. injections less.)

    multiply you average gasoline number by the current fuel price, do the same for the LPG/ngv number

    assuming that your LPG/ngv price is lower... subtract it from the gasoline price, this gives you the money gain per 100 KM.

    take the installation costs of your LPG/ngv system and divide it by the above difference, multiply by 100 to get the gain per KM.

    now you have the distance in KM you have to drive to have it paid of.. depending on your annual mileage... you have now a rough estimate when it starts making money. (rough because you will still consume some gasoline in the warm-up phase of the engine, and that number you will only know after the installation and use of the conversion)

    As to the 10 year old car... that fully depends on the engine type and overall quality of the car and engine.

    Some engines are not at all suitable to have a LPG conversion, so it would be a "double" waste of money, since after a certain time you engine will give and your in for a new one...

  23. You get better acceleration and uphill power with regular 91 petrol

    This should not the problem if your LPG has head injectors with a separate ECU.

    All a question of properly programming the LPG ECU.... last week, after fixing a minor LPG injector thing, we, mechanic and I, went for

    a calibration while driving....

    When we got to a bit of an empty road (some "frontage roads" are good for that), I just went for it, and noticed the mechanic locking himself in the seat, scared the S...T out of him. (2.2 Chevy Zafira), he immediately asked me to slow down, so he could belt up...

    No to much difference in accelerating power between Petrol and LPG, different sound.

    What I generally noticed on my Zafi is that accelerating in Petrol mode and giving it a bit to much does not bring more power, more like choking the engine a tad, with the LPG ECU, we tuned out the flaw, for LPG mode that is...
