Hi All, thank you in anticipation, On taking my Mazda RX8 to have an electrical repair, the garage owner removed my piggy backed F-CON ECU, Sard Injectors and other parts, and replaced with a standard ECU for The Nissan SR20 DET engine, without my permission.

The car runs ok, but have found a knowledgeable mechanic who can either piggy Back or run The F_CON as a stand alone option and reinstall The Sard Injectors and any other parts needed.

The new mechanic checked out the F-CON and started a car in his work shop with it attached, in my presence.

As I have most of the parts already, should I leave as is, install as a piggy back or stand alone option.

Must admit not had a lot of luck with this car, but I have a lot of skin in it already, but do like this machine.

Thank you Tom

The cars running at least, leave it alone

Hi, Kartman, thank you for the information.

Regards Tom

Do you want the car back to factory standard or modified?

What is the F-con going to piggy back? Doesn't make sense for it to be on the Sr20 ecu.

Hi, Kartman, thank you for the information.
