I have a 1972 Mercury Comet I was originally going to put a coyote in but I have an opportunity to buy a complete(engine, trans, harness, computer) 2.3 Ecoboost setup from a 15' mustang for $2500. Considering I'd have that into the front suspension to fit a coyote in there, I figure I'll try something new.
I looked at a stock tune from the repository and the PATS option is available, can I confirm that I will NOT need the factory key to make this work? I need to know what other computers/wiring I will need from the donor car(it's still available).
Thanks.
