Right... I think I have a Custom HP Tuners OS but not sure. I finally fitted my WB02 and am keen on seting the car up on an EFI tune as I have alot to do over the next few months.

The question is How do I wipe it to a stock tune? Below is things I have found out so far.

I believe the PCM has either been replaced or a software version for a 2002 car. My car is a 1999 Gen III (Holden Commodore).
It fails to read anything from the PCM

Anything you need to know reply and Ill do my best to get the information.

thanks

Antony
