I am tuning a car (57 pontiac with a 1998 5.7 vortec) that has a 12200411 PCM installed (it was out of a 2001 G van, express van, etc.). Car runs OK, but needs some tuning. I bought EFI live Personal Scan&tune and installed the software (V 7.3).

When I start up the software, it asks me for the VIN number.... well I don't know what the vin would be for this one. I am assuming it needs the VIN so that it can load the proper calibration files for the data stream?? So could I just use any VIN number that would be right for a 2001 G van? If so, any idea where I could get a VIN? I also noticed that the 12200411 PCM was not on the drop down menu, can someone help a newbie out?

thanks,
