Hi team

I have been searching through numerous other threads in regards to LS1A to 0411 ecu swaps, but have found no definitive answers.

What operating system are people using for this conversion? I have tried 12221588 (2002 C5 LS1) but have communication issues with the BCM and IPC, from what I understand
the 1997 BCM and IPC wont communicate with 12221588 2002 software due to different class 2 data handling. I have been told that 12212156 would be a better OS to use this is from a 2000 C5 corvette.
I have 12212156 from a camaro but Im not sure if this would be ideal? Does anyone have 12212156 stock file from a 2000 corvette I can use?

Also in regards to VIN swap, apparently VIN needs to be changed in ECU to match other modules in the vehicle, but Im unable to to do a vin swap as the 1997 VIN obviously does not pair with the later model operating systems. What is needed to be done to change VIN to original VIN in 0411 ECU? or does it even need to be changed.

Any help would be much appreciated

thanks
