ECM needed....

So, we've rebuilt the LT1 in my 97 ws6 and my builder told me the computer was apparently tuned by someone prior to my ownership of the car. Whatever software they used allowed them to put in a password and, of course, noone can get into it and I can no longer get in touch with the guy I bought the car from.

He took the car to the local Pontiac dealer to see if they might be able to flash the computer back to factory original and go from there but they have not yet been able to get into it either.

My questions are... A: Do any of you know of a way to beat the password or reflash back to factory? B: If I am going to have to get a new computer, who's my best options?

Thanks for your help in advance.

I believe your question would be best answered if you go to the gearheadefi forum. They are experts in pcn programing over there.


You next option would be to contact a pcm programmer. I recommend LT1 PCM Tuning - Welcome!
