[james workman]

02 4wd tahoe currently 12216125os checked drop box with no luck does anybody know where i can find a matching os for a 80e to do a segment swap, and then i have a efi live and i have 0 experience if someone could tell me where i can find information on doing the segment swap from the beginning, alot of information assumes i would know the basics but i dont any help would be extremely helpful thanks in advance

There may not be a 12216125 4L80E file... you may have to run a 12212156 4L80E file instead.

Thanks i appreciate the reply, i searched all weekend and when i would try to open a different os number for comparison, my unit told me it was wrong and wouldnt open it, so i ordered a harness that will operate the 80 off of the 60 tune hopefully it works as it says it will thanks again

The 2002 Express van with an L31 5.7L engine had a 4L80E as an option. This should be in the database somewhere. If you can't find it, I can upload it.

I can't find this. I'm needing a 4L80e equipped 12216125 OS

Avalanche with the 8.1 had an 80E behind them, were DBW, and used this OS. You might need to bench flash a PCM, I havent found any tunes in EFILive format with this OS and 80E trans segment.

Sorry about the delay. Here it is.

[joecar]

Close... but he's looking for 12216125.

[WhisperPC]

Sorry. I must have misread the OS number ... twice.

I know, I have xidlesia on those two calibration id's

12212156 vs 12216125

and I sometimes type this

12212165

so now you can't tell which one I really meant
