Ok, I am going to have 4.11's and a trutrac installed hopefully in the next few days.. I am also(as money permits) putting in a 4l80E..

From what I understand, on HP tuners it is rally just replacing the engine codes(ses light infos) and the transmission tables from a 4l80E tune over the 4l60E codes/tune file data.. Correct?

As for the 4.11's and the locker.. Will I have to change anything in the tune for the locker? How do I adjust it for the gear size on HP tuners? I just want to have the PCM's transmission/rear end settings correct enough to break in the tranny and rear end gears properly. I will be having it tuned later on a dyno but that is still months away.

I do own HP tuners and it is unlocked from the last tuner still.. I dont do my own tuning, but am competent enough to make basic changes like the tranny tables and (hopefully) the rear end tuning.

Thanks guys I appreciate it! The trucks slowly getting back together lol.

The new rear-end/gear change will be easy. The 4l80e will be a bit harder. You have two choices, segment swap (done by ec tune on the HP Tuners forum) or start with a completely new bin file from a 4l80e equipped truck. It's not as bad as it sounds though as you can copy and paste all your current engine tables on the new "4l80e" bin...

 

If you had EFI Live I could do it for you relatively easiely, I do have HP Tuners but I am not as famaliar with it as I am with EFI Live...

 

I just played around with it a minute ago and found the gear settings and everything.. not that bad at all. Ill have to play around with my pcm files for the tranny later. I should be dropping off my axle today to have gears and locker installed, then I can finally drive my truck again(although I will be stuck in 1st, 2nd and occasionally 4th lol) at least enough to go buy some gas for her when theres no traffic on the road.
