L99 PCM to LT4
I bricked the PCM of my 1996 Corvette LT4. Bought remanufactured PCM and got one from 1996 Impala L99 4.3L. Same part number as LT4 PCM.
I tried to flash my Vette calibration file and operating system using JET DST to the new PCM, option Force full program enabled. Flash aborted: "The calibration is not correct for this vehicle".
Managed to import Vette calibration data to the L99 file and then flash this .jcl to the PCM. I guess I now have L99 operating sytem with LT4 calibration.
Is the operating system on L99 box different from LT4 box? Am I good to go or should I take the box to dealer for updating the operating system?

Fuel Injected!
Use the PCM recovery option and your LT4 calibration. I've had that error pop up before and either I changed the vin to match or used the recovery option.

PCM recovery option resulted the very same error:
"The calibration is not correct for this vehicle".
