Does the old pcm have to be in the car to do this? Because I made an appointment with honda and it's fairly cheap. I have my old pcm out the csr and I have another pcm that's gonna get reprogrammed
@@BestCarFixes yeah but don't you need the Vin number and all that from the original car? Not only that honda told me to bring in the old one as well so they can transfer data from the old one to the new one, but im also sayin does the PCM. Have to be in the car for programming or can it be taken out to program it?
