98-00 Vortec and LS1 Computer Swap Custom Tuning

[winford hackworth]

Thanks for the info. I was wondering about the LS swap and keeping a/c going. Do you know if I do the LS swap will you have to change out the complete harness

There are different variations. If you do the 0411 ecm swap, then you are most of the way there as far as the harness. When swapping to the LS its a matter of adding a few wires and changing some pigtails. I have not done the swap yet but researching as much as I can before I proceed. Found a lot of info on a FaceBook group: LS Swapped 88-98 OBS Trucks/SUV. Its a closed group so have to ask to be a member. Once in look at the pinned posts and info section. Lots of good info in that group as well as good info on this current site. Again you will need to ask Lextech here for ecm pinouts and you will be well on your way for a swap. He wil need your vehicle specifics.

No problem. The file section on the FB group is where all the good info is as far as the swap.

Alsocan you program the 4l60e to shift very firm at wol ?

Speaking from experience here... Unless you want that 4L60E to die pretty quickly, don't mess with the tuning for it.

Sorry I missed your question. I have not been on here in a while. I have been on the swap page more. Sorry, no i do not have ecm's or a way to program them. There are many people that can do this. Me personally, not only did i get the wiring pinouts from Lextech but i contacted him to set up and program an ecm for me. I have a later model Blue/Green ecm from my 2003 donor that i will be sending him and he will be programming for me. The green/ blue ecm's are more a drive by wire ecm versus the 0411 red/ blue ecm's are more a drive by cable ecm. Some of the green/blue's can be set up for drive by cable, but not all of them can.

Yes, The 12200411 PCM can be installed into a 96 truck. PM me your e-mail address and I will send you the wiring file for the PCM swap.
