I would appreciate it if someone could let me know if there are any special procedures when replacing an ECM in a '91 Olds Cutlass Supreme 3.1 V6..?
Do you just need to exchange the MemCal from the Old ECM into the New ECM..??
I picked up an ECM from the wreckers out of an '88 Cutlass Supreme International.., I just want to make sure I am doing this correctly before proceeding with the replacement.
Please advise.., thank-you.
