CF4 Injector Coding into a CF3 ECU
I've got new (CF4) injectors. I'm trying to code them using FES in my (CF3) ECU.
I get message "FAILED TO EXECUTE". If I use one of the 4 codes stored in the ECU in any of the 4 cylinders it works fine, descarding software/cable problems.
Not knowing a thing about IMA coding, my guess is there is at least one check digit in the 9-digit injector code. A CF4 injector probably uses a newer version of coding my ECU does not recognize.
Does anyone have a solution/workaround for this?
