    Spark source Torque control

    I've read and read and still don't understand why my car pulls spark from torque control rather than borderline MP's. I also only get this from 3300-3800 rpms. After that it's all borderline. It's basically right when I snap the throttle. I have read about changing max torque 1 and 2 and setting the spark cut torque ratio to 1 and that should solve it. I have not tried it, just wanted to verify since I am getting mixed answers that I've read within the forums. Also I log knock and it almost always has a value from -1 to -3.5 throughout the rpms at wot. I'm assuming this means there's a little bit left of timing I can further advance. Car is a '20 GT m6. Thanks

    I could not get a current log due to the weather here but Here is a log after making the first timing changes. The torque control is there as you can see. This is a longer driving log with a couple small WOT pulls near the middle of the log.
    The v4 log is the same tune in the evening after work. Similar log, same tune, just in the evening.

    Alright so i was able to have the spark source pull only from the borderline MPs by turning off anti-shuffling. My next question is as ive been adding timing slowly to some of the MPs and ive noticed on the knock correction the car has been adding even more timing compared to the first initial timing log. Off the stock tables it would add somewhere up to 3.5*. Now its showing around 5* of being added. To me, this makes no sense. You think it would get less and less as i added more and more but it seems to be the opposite effect here. Am i missing something?

    It depends on which tables you're adding timing to and what your knock advance limit is.
