I am trying to replace my ecm on my 2003 f150 4.6l v8 xl triton truck but I am confused on the whole programming and calibration part. First, where on the picture I attached is the calibration code? Second, if I am going to buy a used or re manufactured ECM, what do I need to do programing and calibrating wise to get it to work with my car? I am confused on the whole process. Any help would be appreciated

the info is on the pcm label. You'll need a scan tool to reset the cluster and pcm before it will start. You may need a minimum of 2 keys too.

Where is it on this pic then?

You can order it by the part number 3L3A-12A650-DD (engineering number) or the "tear tag" DOI3. You'll still need a perameter reset between the HEC (Instrument Cluster) and the replacement PCM. You'll probably need to see the dealer for that.

will it need any calibration? or does it already come ready to install?

cjcnomor4

If you buy new it will probably need a program. If you find the right one used it wont.

what about the PAT system? Will i need to take one to the dealer or authorized mechanic to reset it?

You'll have to get the truck to a dealer for the perameter reset.

interested in cost of having the dealer flash one. Mine went bad probably getting a new one. but I am far from a ford dealer and will have to tow it. so also wonder what people have paid to re-flash it.

Cost varies shop to shop, the industry standard amount of time for such a process is 1hr labor.
