how do i reprogram the pcm and where might i find it? what does pcm stand for?

 

PCM stands for Powertrain Control Module. It is the computer that runs the engine and transmission.
It's located behind the passenger's kick panel. The connector is on the engine side of the firewall, below and behind the battery.
Why do you want it reprogrammed?
Your dealer can reprogram it for calibration updates that Ford comes up with. For more power it can be reprogrammed with a programmer such as the Superchips and Diablosports ones that www.motorhaven.com sells.
