Stating from scratch as I don't know what is actually on my PCM

[Behold]

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

It looks as though it thinks i have OS 12225074 if this is of help.

See if you find the stock tune file for your vehicle with that OS id at www.holdencazy.com.

When you say "it fails to read anything from the PCM" are you referring to pids or the the tune...?

Edit: oh, I see, you can't read the tune from the PCM because it's an HPT COS.

You will have to have someone with HPT full flash a stock tune into your PCM.
