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

    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?

    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.

    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!

    Thanks Guys, we can look to add it, but everyone is asking for it over many different PCM's and TCM's, it's going to take time and I'm sorry to say can't be classed as a high priority add.
    Need official EFILive help, please go here.
    For tuning support please post your questions on this forum (or other auto forums).
    Sorry if I don't respond to your PM, don't take it personal.
