HEY GUYS, I JUST PURCHASED A NEW PCM FOR MY 01 GT. ALL THE NUMBERS ON THE UNIT MATCH SPECIALLY THE ID NUMBER (GIZ2 IN MY CASE). DOES IT NEED TO BE FLASHED OR REPROGRAMMED? APPRECIATE YOUR HELP.

to properly do it yes it must be programmed to the vehicle. you download the data from the old one with teh IDS, and then upload it to the new one. or else you have to go by as-built data with the IDS.

PCM/Cluster PATS programming!

Why are you replacing the PCM?

Reminder, the replacement PCM will NOT have the PATS key ID's. Therefore, the PCM will not start the car.

The PCM and Cluster also need to be programmed to know each other. Otherwise, PATS will keep the car from starting.

Optionally, PATS can be disabled with a tuner.

i am replacing it cuz its failing to send siignal to cyls 1,2,3 and 7 to fire (cops). i ran all test available (wiring, cops,plugs, etc) per ford maintenance and troubleshooting manual and sends me to problems w the pcm. im going to take the new one to ford ($94 to reprogram) hoping that this will solve my problem.
