early 99 pcm question

[adavis11]

I have an early 99 7.3 4x4, with auto transmission and I am wanting to upgrade to the newer pcm. I just have no idea where to start. What pcm do I need to get, how do I install it, and do I have to do new injectors and high pressure oil pump also or can I just do the pcm.

does your truck still have the XLEV pcm code?

You don't have to do new injectors or anything. Pcm swap is easy. Look in the tech files under the 7.3 mod section, and there's a post by Marty I believe that is about installing a chip in a computer. It will tell you how to take your computer out. Pmt1 or the like is wanted over the xle pcm codes like the early 99s have. Easier to tune, more capabilities. I dunno how or why, but its just what's always been said. But really, if you kept your early 99 pcm, its not bad. I ran mine for as long as i have had my truck. Until recently, and not due to really anyone's fault I switched over to a pmt1. But it wasn't because mine wasn't capable or bad.

I heard the old pcm on the early 99's run on 110 current and the newer pcm is 220, in which the 110 pulls more amps and can burn up the wires that plug into the injectors. I don't know if this is true or not, but that is my main concern. I am getting ready to install an edge evolution programmer and was wondering if this would make the wires burn up faster.

WRONG!

The IDM on the OBS and "some" E99's is a 110v, the L99-03 have a 120v IDM

So am I ok to run the original pcm with my progammer?

[HVAC SuperTech]

Yes, of course

IDM's say 110 on them. It's a common misconception that they are 110v.

The IDM's from 94-03 powerstrokes are interchangeable.



For the OP's sake, you want a Late 99-01 automatic PCM. Any of the DPC-422* pcm family... IE: PMT1, PMT2, etc...


*Don't hold me to that number... just off the top of my head.
