I hope you are doing well. My name is Batuhan, and I am from Turkey. I own a 1995 Buick Park Avenue Ultra Supercharged, which is an extremely rare vehicle in my country—only three units exist here. Unfortunately, there are no experienced specialists who truly understand these cars.

I recently replaced the EPROM and purchased an M27C256B EEPROM chip for programming. However, I do not have the stock BIN file, as my original chip was damaged beyond recovery. As a result, the car is currently unable to start.

If you happen to have a BIN file for my car'* ECU, I would truly appreciate it if you could share it with me. Additionally, I can provide photos of the engine and ECU if needed.

Thank you in advance for your time and support. I look forward to your response.

Best regards,
Batuhan

do you want to tune the car or just repair it and get it running

Might be better off buying a refurbished PCM. I've seldom seen anyone outside of a PCM rebuilder able to do much of anything with pre-1996 PCMs.
