    I'll check the torque pid, if you're running anything that's significantly increased horsepower the estimated torque is going to be way off unless you've adjusted the map accordingly.

    For the spark pids, are you logging, SAE or common identifiers?

    Sorry for the late reply buddy got held up at work, anyway regarding the torque issue the car is mostly stock the only modification is cold air intake + about a 100 hp NOS shot and they is no way it makes 1500 nm torque at part open throttle so there is definitely something wrong with the PID it self, wrong source for the calculation or something.
    Regarding the spark i am logging both the SAE is right on the spot the other one is in a deferent planet but its ok never mind that i have another question about the knock value ( feedback, threshold & count ) can i rely on the values displayed the reason why i am asking is that i did a couple of runs twice with the timing advanced stock timing with a 100 hp NOS shot 3 and 4th gear all the way to the limiter yet it did not register any knock at all like absolutely nothing which is a bit strange to me coming from a Hemi background so can i rely on that feedback?

    Update to latest beta and repoll, i spotted the error with your torque PID. Sorry about that. It's still going to be a direct reflection of the Estimated Indicated Torque map though.

    The knock feedback/count PID is after considering the knock threshold table. So it may be filtering out if you believe there is knock, but for just a CAI and spray it should be pretty reliable from the stock table

    Thanks buddy yup the knock feedback does seem to work fine i pushed it just a bit more than i should to see weather it would read something and it sure did so its all good so thanks again brother have a good one
