    Tuning for torque converter non pwm 4l60e

    So I just want everything that can be done on the pcm side. My gears are 373 with correct shift points and Solomon bumped up line pressure.

    I have the Solomon power tune FYI.

    Can someone help me in this area? My stall is 3400 yank power adder on a 94 Z28 NON pwm


    Thanks

    Lane

    I am relatively new so I don’t know for sure, but from a glance as someone who messes with ECUs, the question of what exactly you’re asking for comes to mind. Specifically, what sort of adjustments are you looking to make? What is the car doing now, and what is it you expect it to do after the changes are made?

    Forgive me if I’m just missing something obvious. Best of luck with the new transmission!

    OK here's what I am asking for. First, thank you for respnding
    The 94 so no pwm. I have 373 shift points from Solomon. All that's been done for my transmission as far as I know his bump in line pressure that is it I've asked him to retune for a couple things he seems and I know what I'm talking about. I'm having trouble with stall wall. I would like better tcc cycle and better downshift response. Seems tcc is lazy. I have the ya k 3400 power adder with trans go, sonnex servo kit 2 and 4, tcc apply(installingntonight(sonnex boost valve kit BETTTER then transgo). And hd 2-3valve. I just feel it's not hitting like I've felt in tuned LT1S, but notmine. Feel as though midnshift it's revving to hi. Again this almost stock tune for the tranny.

    I want more performance over drivability and mpg.

    I've heard changing the VSS tables help some? Maybe make the TCC 100/0%? I know I am hitting stall wall for sure and I'm leaving some performance behind. Lol oh yeah also have external cooler.

    Any tips Justin's advice and maybe some things I could borrow from you you guys for the tune or that I can add to this tune I'd really appreciate it I want to go to see the trash about 5 days and one improve on my times. thank you

    i don't know much about automatic tuning but solomon can solve the stall wall for you, why don't you ask him for a touch-up? hes a pretty nice guy as far as that stuff goes and he's tuned way more LT1s than anyone here has.

    i do know from my other cars (with non-electric transmissions) that if it's a track car with a big converter, the TCC has nothing to do with performance at the track, you're always out of the range where that thing will help. just let your stall point do its thing.

    I did some reading about the "stall wall' before installing my converter - ended up not having any issues but I did bookmark this for reference:

    This is what Solomon did to my tune. Lemme know what you guys think. Just talking with him he's a nice guy but I fear a little conservative on this. Any changes guys please feel free.
