Hello, I am trying to change the vin to a 2020 ECM but it keeps giving me this error " Response $12 "sub-Function not supported or invalid format" im using the 7.5 scan tool. I also tried using the regular V8 scan and tune one and it doesnt want to change. Please Help! I have it hooked directly to ECM using the CM2350B and the EFILive tool
