tbss 4l80e segment swap

[spent21]

i've run into a problem with the 80 swap...
I've got everything ready & repinned the harness; however, I can't find a tune for the hpt segment swap. my understanding is the Os must match, & i can't find one in the repository from silverados, suburbans, or expresses.


'07 tbss E67/t42 (12611938 -> 1250241 Speed Density - 2 bar) t42 with the 24238660 Os, but I can't find another tcu tune for the 4l80 with the 24238660 Os

any help here besides getting the pcmnc harness?

This was answered very well in the last thread you asked this in.

If you can't sort it out, send me a PM and I can try to help. May be easiest to just buy a TCM with the correct OS/segment swap stuff done, then you can just install, read it, and start tuning.

There likely won't be a tune file floating around with the combo you need, and if there is, you'll have to pay 2 credits to license it so you can flash the TCM unless you have unlimited 07 TBSS' unlocked.
