4l80e parameters to prevent TCC from disengaging in 4th gear

[Taz]

... I did hear that it can be done in HPT, but was not aware that it was now possible with EFILive ...

That is an oversimplification of what I had posted - and is not accurate.

An "off the shelf" version of HPT has some (many Gen IV are missing) of the 0% TPS TCC lockup parameters. An "off the shelf" version of EFILive has none of these.

Some tuning softwares allow the user to add their own parameters - thankfully, EFILive is one that allows this user specific customization.

I have invested the time and money to add many additional parameters to my version of the EFILive software. I have added parameters (guessing more than 100 by now) to operating systems from 1998 to 2014 - a necessity of operating a successful commercial venture.

Taz,

Here is my 4l80e tune. If you can set it so the TCC stays locked on decel I would greatly appreciate it. Thanks for your time!

[Taz]

Done ... per our previous discussion.

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...
