I've recently read that HP Tuners added tables that now allow the tuner to prevent the 80e TCC from unlocking when the throttle goes to 0%. I downloaded the latest version of EFI live and quickly looked, but I don't see any new TCC tables. Any chance for EFI live to add this ability?
Can you pm me a link to that (regarding HPT)...
Subscribed! Any updates?
Well, long time but here's an update. HPTuners has a new table called "minimum throttle release." Tq converter no longer unlocks at 0% TPS. This would be highly beneficial to have for those of us with EFI live.

OK, thanks for posting back.
Yes, this would be a HUGE addition for all supported PCMs (even the LS1, Id kill for a P10 update with this in it. Tell me where it is in the code and Ill build a .cax if need be.) and the T42!
I'd be all over helping to test those T42 files!Quote:

I would love to see this added. (LS1b for me)

+1 x2 on LS1B.
LS1B and T42 would cover most everyone...any thats a ton of OSs I know. :(
+1 x 3-1/2 on the LS1B!
+1 for ls1b and t42
Another vote for LS1B !
I'll throw in my 2 cents worth ... LS1B would take care of most of my vehicles I tune.
Been a few weeks....any updates?
LS1B as well. Seems to be an issue for anyone with an 80E and an aftermarket torque converter.
I need this !!
Bump...would REALLY like to see this. If it can only be for 1 PCM/TCM, Id say T42 first then T43 (dont know if these do it or not, havent tuned enough of them) then LS1B.
Word! I second what Erik said.Quote:

Yes that would work, but HPT only has it defined for a few OSs at this point so if EFILive defined them for the majority of OSs that'd be fantastic.Quote:

Post your tune ... I can set the TCC to stay locked at 0% TPS on coast down for you.Quote:

For Gen IV OS - I had chased down these parameters on my own - no small amount of time involved. I charge a fee to patch Gen IV OS - to help recover my R&D costs.
HPT has just released these parameters for a handful of Gen IV OS - only one of these OS was used in truck applications though.
Good to hear. I'm doing an 80E trans and segment swap soon and was hoping to be able to prevent the TCC from unlocking when letting off the throttle, without using the 60E segment and relay mod. I did hear that it can be done in HPT, but was not aware that it was now possible with EFILive.Quote:

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!
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...
Any updates on this? Working on my 4l80E tune now and would like to work on this.
its simple.... anyone have paypal????
i can fix all up those tunes.
How much?
Curious as well what you would charge?
