Winflash has an option to read the vin# stored in the PCM. No matter what I load into the PCM it always shows a Camaro Vin#, LT1, Made in Canada....etc.
What software are you using to flash/edit the .bin files?
Maybe I need a factory manual .bin from a 94-95 car?

Is there something that I am not doing while flashing the ECM? I have loaded a factory Vette BNDH.bin, but it was an auto and my car is a manual, and it still does the same thing. I am using Tunercat Winflash for flashing and TunerPro RT to mod the .bin.

It is possible that the problem you are having is simply because of this - the CCM reads the VIN and says "uh oh!"
Next time I have the tuner out I'll try putting an F VIN in my PCM and see what happens.

I use tunercat. Changing the VIN in the PCM is a separate procedure from uploading a program. Tunercat knows how to do it, and I think some other tuning programs don't do that.

Hi Tim,
The file you sent looked OK so that's probably not the problem. I've never done this conversion in a Corvette but there are minor differences between the Corvette and Camaro PCMs so it could be the problem is that you are using a Camaro PCM and not a Corvette PCM.
You might want to check some of the tuning forums to see if anyone else has done this conversion.
Best regards,
TC
It seems like if I could change Vin and engine type I could fix the problem.
