Re: PCM replacement – need some insight/help
The remand from local parts store or even a pick & pull should be model specific. I had a PCM sent from parts_.com for a Picifica and had a buddy of mine flash it with his Autel. If the PCM is guaranteed from a local auto parts store to be compatible to your vehicle then why spend hundreds more thru a dealership? As far as a performance and mpg issues, if it weren't compatible to run your vehicle, then it wouldn't probably even start. Just my opinion, from experience.
As far as reprogramming a unit you install, sure, but be prepared to open your wallet. In my area, the minimum to just flash/enable is $90 and up. Good luck.
