Would like to know what it would take to make this 2wd os to an 4wd os. I converted my 2011 v6 4x4 to an 6.0 4x4 everything is working but I can't make it change when set to 4low. I'm sure it needs the 4wd os, but how do I go about it?07tahoe2wd.hpt

Probably going to have to write a new file to the computer that was suppose to have 4WD from the factory.
I'd use a GM tool do to something like that, then license the new file and adjust the computer for the 6.0 swap.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
I thought that I could do a segment swap thing or write entire a diferente os into this ecm. But it?s not that easy?
Not sure if the segment swap stuff even works on the GEN 4 computer. The file you posted doesn't even have the transmission TCM read out either, it just has 2 tabs under the transmission tab and says trans type auto.
Flashing another file will cost you 2 more credits, then it might ask you for 2 more afterwards because you created a new VIN/OS on the computer you just flashed.

12614088 is OS for 07 Tahoe PCM (E38) 5.3 Z71 4x4
24235341 is OS for 07 Tahoe TCM (T42) with 4L60E 4x4
Hope it helps.
Can that info be written to my ecm and tcm?
