[cbradley]

I sure this is out there somewhere but how do I find out my Pcm code and where is it

[cbradley]

Nobody just trying to figure if a used chip will work on my truck but most have a code that thy will work on but I don't know my code or how to get it

On the side of the PCM?

[cbradley]

I don't know that's why I am asking . Where is the Pcm ?

[jesilvas]

OOOOHHHHH ok. Beside the parking brake. Just a box in a plastic cradle.

Video - DP-Tuner Install

Diesel Movies - I install a DPTuner F5 chip in my buddies truck. Positions were Stock hi idle 60tow 80econo 120 race 140smoke.

Watch the video, it shows you how/where to remove the PCM.

Mine had the sticker in 2 places, on the part of the PCM plug in the firewall, and on the plastic cover you have to remove to install the chip.

The PCM is down by the emergency brake pedal. Simply unbolting it won't help you much. On the other side of the firewall there's a large plug with a rather huge bundle of wires going into it. The plug is held in place by a 10 mm bolt. You have to loosen that bolt and unplug the PCM before you can take it out. This plug is a bit difficult to get if you have big hands and arms.

Once you get the plug off the code is actually readable if you have good eyesight and a mirror. You can get to it easier if you unbolt the fuse box. You can also unbolt the fender and pull it to the side. I didn't need to do that to get to the PCM, just removing the fuse box was enough for me.

Thanks for the help

confusion along the same lines here. i hear the PMT1's came our around 01? and then i dont recall the model, but there was one for the e-99.

anyway, in my org searches i cant find what PCM a late 99 or 00 would have... does anyone have a simple year to truck (f250 and 350 only, not amblance, etc.) chart? i ahev an auto.

U really should pull it so you know FOR SURE which PCM is in it. It it ever had one fail, or a PO upgraded it, a different one may have been used.
