Thread: Autotune started stopping.

  1. #1

    Default Autotune started stopping.

    My auto tune keeps saying Learning then about 5 sec later says not learning, and never goes over 12%? I've been driving around, steady speed, stoplight to stoplight and even some highway bursts.

    When the Learn Table values stop making significant changes, the ECU is finished self-tuning. The purpose of the Learn Table is not to achieve similar values, high/low values (0% or 100%), or any value in particular. It's simply indicating the amount of tuning applied to the Base Fuel Table. Read this thread (LINK), that's what it's all about.

    Thanks for all your help. One other question. I'd like to lock out timing under boost, like 15° from 1 psi up. I can just set all cells from 0 psi up to 20 psi across from 1800 to 7000 RPM? The WOT timing table only retards x amount of timing per boost when your WOT? By setting all the cells in the Base Timing Table this would limit timing to 15° when your getting into boost, but not WOT?

    The Base Timing Table is fully user programmable. Program it as you'd like.
