    Question accel thresh LTG Camaro

    I want to make power beyond 5.5k rpm but idk where to start i found accel thresh do i just set that 0 and start there, where should i start with? i found one thing on it and it was guy on laggy laptop he set his to 0, but i couldnt hear what
    mods are pretty simple, CAI, DP, and some cooling and fuel mods.
    Engine > Fuel > Cutoff, DFCO > Acceleration Based > Accel Thresh

    You want more power past 5.5k, or you can't rev past 5.5k?

    The quick help for that table is pretty useless if you ask me, so maybe try dropping the values by 25%, or 50%, see what happens. Some ECU's don't even use this table from what I've read so you may just have to change it and see what happens. If you're limited to 5.5k you may need to look at the transmission shift schedule tables.

    What else have you done? MAF/VVE dialed in? Cam adjustments? Injection/spark timing?

    I want to make power beyond 5.5k from the logs after that torque just kinda drops and i was wondering where that was coming from around ~400@5300 tq to ~290@5600, only ideas i had was the Accel Thresh table and Virtual Torque, i have my VVE all good and my spark tables aswell, i haven't done much with the cams yet but will soon

    Update: On a E80a ECM, I dropped the values by 50%, results, cut a tenth off my 0-60 havent tested any other metrics yet, and it still dropped off torque pretty fast, BUT it was slightly later on in the rpm range around 5800ish i would get 290, Ive done a couple logs over the last 2 days, and results were pretty similar,@5600 the min torque was 294@5632 max was 310@5614.

    Both could just be luck since i only logged around 40ish minutes of driving,

    I will do more research to see how much i should change it, i will also log a zerod out table to see if there's any major change

    Accel threshold is a limiter and you can safely zero out the whole table .
