05 pcm

Any of the Florida guys happen to have an extra 05 pcm? figure its worth a shot to ask. Want to give something a try, or if anyone outside of Fl that has one thats ok too haha.

Curious if it really is as simple as a plug an play for an 04. I don't believe I've read of an 04 doing the upgrade just always 03 to 05. But I'm sure if it is that simple. Mine will lock up like Keith an Don's did, but if I can get a trans tune in beofe that happens on Diablow I may be in luck. The stock shift schedule for these trucks SUCK!

If you want to just try it out and can't find a free one, eBay has a ton of them for $50-150. Mostly junkyard pulls and wrecked trucks

I used a salvage yard pcm at one time without flashing it. It worked flawless for a couple years. Then i had it flashed with manual trans software. Was told part of my 03 tuning woes were because the auto pcm when flashed with manual software there are problems with some hardware termination. Not knowing better, i bought a 03 manual pcm from my local parts store and had it flashed with vin for someting like $225. IMO that is pretty cheap solution. Of course still being a 03 pcm it didnt tune any better than the previous flashed pcm. It was just another step in Red's evolution.

This is the harness i made to install the two additional o2s. One plug is forward sensor and the other is the rear. You can see something like three wires that are pinned. They will go into empty holes in the plugs. Two wires are spliced to existng wires anf the rest go to the ground stud near the pcm.
