I have pretty much finished swapping V8, transmission, power train, and PCM into a V6 chassis. My question is this, I have the keys to both cars. Can I swap in the PATS detector and key cylinder from the donor into the engine recipient? I am not opposed to getting a tune to deactivate the PATS but it seems that all of the tuners that I have checked require a custom tune. I would like to at least be able to start in my garage and see if everything is working OK. I am waiting for a cold air intake to arrive and do not want to have to pay for a custom tune twice. So can I just take the little pats thing and the key cylinder out of the donor car and move it into the recipient? (I have a wrecked Mustang GT that I took all of the parts out of and put them into a former V6) Thanks!
