Ecu Shop Boost Speed

[thaitim]

Hi guys i have a 98 Triton 2.5 Diesel Auto.

Because it's an auto when u put your foot down theres an annoying delay whilst u wait for it to do its stuff.

The Boost Speed box sits in your car & is fully adjustable as to the sensitivity you want.

Its wicked works really well would recommend!

Thaitim,

How much did u paid for that stuff?

Annoying delay you say .. what do you expect from a diesel and auto combination?

Wasn´t it you BTW who asked a few days ago about Triton´s , found one fast did we??

Ha ha yep it was me & yep I got one.

Very pleased as well so far

KIFKIF the Boost Speed box costs 8,500. I phoned them up & they came round & installed about 2hrs l8r.

What exactly does this boost box do, sounds to me its a lean out thing, robbing fuel to get it to boost quicker....could be nasty.

Modern diesels generally seem to have a lot of headroom for squeezing out more power... Friend of mine had a BMW 520d, got it tuned to go from about 160hp to 200ish, made a real difference... I suppose there's a slight bump in the turbo pressure if this is electronically controlled, and more efficient fueling.

But it does make me wonder why manufacturers de-tune them like this? and most importantly how will it affect the lifetime of the engine...

To reduce warranty claims on one hand and keep some performance gains for the new model....when it arrives!

Yepp.

And to be able to cope with lousy fuel quality. Reduce strain on transmission. Emission.

Every mass produced engine is not tuned optimal, to expensive. Its tuned to what the marketing department require, not more.

The opposite actually.

My understanding is their ia a surplus of air in detuned diesel engines (by as much a 50%) and by increasing the comonrail pressure, more power and torque are achieved.

Comonrail explained by Robert Bosch. Here.

About inserting tuning boxes. Here.

The idea behind a diesel tuning box is to intercept the signal between the ECU and the injection system, and basically allows it to inject a more optimal amount of fuel into the cylinders thus producing more torque and power. Because of this the engine runs more efficiently. Fuel economy is also improved because you would have to use less throttle to achieve the same performance level, and because the engine is tuned to burn its fuel more efficiently.

There are 2 simle ways

1. Increase length of injection.

or

2. Increase pressure

Both providing more fuel and air to burn

A diesel engine running lean does no harm whatsoever. Unlike with a petrol engine where running lean over time will likely burn a hole in your piston

Remember, basic diesel engines work perfectly un-throttled. Power output is controlled by the amount of diesel injected, the airflow is not controlled, i.e. no butterfly valve at all. So most of the times (when not accelerating) diesel engines are running lean of stoichmetric. It does increase temperatures, but the engine is designed for this.

I v been chipsing turbodiesel engines since 1996. No problems with engines or engine lifetime. Taxis still do +400k km on same engine

Some problems do exist though

1. Emission

2. Temp and wear on transmission. Temp can be reduced by more or larger oil coolers. Wear can be reduced, but not elliminated, by more frequent oil replacement.

You can actually re-flash the ECU yourself. I have a 2009 BMW 320 diesel and I have re-flashed the ECU myself. Standard is 177bhp 350nM. Now 220bhp 450nM. You really notice the difference. If I wish I can restore the normal map when I put the car in for routine service. Cost was about 18,000baht

Excellent explanation, Thanks.

I must look more into these oil burners one day
