I'm new to EFI Live and wanted to look at transmission tuning but there's no trans icon in navigator. When I click on the two gears that says "Engine" behind it, it says "NOT USED, this segment not used in the Duramax LB7 ECM" at the bottom of the navigator box. Maybe this is a dumb question, but I'm lost. Thanks for your help.
You need to read the TCM tune to tune it.. It;s not in the PCM like a gasser. So when you go to read the tune instead of reading the LB7 ECM in the pull down menu select LBY/LLY Allison TCM instead.
Wait do you have an LBZ or LB7. you say LB7 in the post but in the thread title you say LBZ?????
LBZ, that's why I'm confused
when you read select LBZ ECM then LBZ/LMM Allison TCM...
Ok, I got it now, thanks!
