Thanks! I'll take a look at it tonight.

Hey Taz, it sounds like you have a solution to this issue, which I have been hoping to see for a while. First off big thanks for that! Especially since I am relatively new to this community, I don't want to come around looking for a handout so to speak from others' work. Is this something you have a .cax file for, or would you be able to apply the fix to my genIII tune file? Again, I understand if this isn't something you want to just give away after a lot of your own time, effort, and investment so if you do have any conditions or fee that would be in line feel free to PM me. Thanks!

Has there been an update to this? Does EFI Live support the TCC at 0 TPS? I am currently trying to figure this out with my Tuner...

depends on which transmissions... these enable the drag control on the trucks... not done so on the cars....

My application is a Sierra 2500 with the L29 454. I read where the member going by "Taz" had a solution to this, but I have been unable to find out how or if I could get him to look into my tune for me...
