Just an FYI, I can get my hands on new 1996 and possibly 1997 computers, no VIN entered. If you desired to do so, we can sell it w/SCT to flash it into the EXACT ECU you have right now if it is a differing software version.
Note: This is assuming that 1997 ECU's are currently not available brand new as that may be cheaper, but highly unlikely there are any around at this point.
