Thread: demon throttle body reason for throttle cut??

    demon throttle body reason for throttle cut??

    11 challenger, fully forged, procharger, midrange cam with phase limiter, nothing crazy.
    lots and lots of these have been done.
    for me this is first one with demon tb and it's the only thing i can see different from others i've done.
    i look at airflow tables, diagnostic tables, the trans limit tables and i can't find anything different about this file but i'm getting an extremely consistent throttle cut at 4500. dyno or street.
    i'd appreciate any help. i've moved all kinds of tables every which way and it's always there. starts, idles, drives fine. just this wot cut. and no code or flashing bolt in the dash either after it happens.
    thanks

    only big change i see is you put neural network back on.
    changing fan speeds and speed limiter and some afr couldn't possibly close the throttle.
    and i've done lots without NN, but i'll give it a try.
    i can't see what codes you changed in compare mode. what did you change there?

    you missed the part "fully forged".
    long tubes, no cats and 175 degree Tstat also.

    leveled the speed of the automatic transmission after 80%. from your data. Also for the test

    Nevertheless, I do not recommend lowering temperatures. The most extreme is low 95, medium 97, high 99.
    Why is nothing done in the program to work without catalysts?
