    Normalizing them effectively disables all knock control.

    but why are people doing that if you not knocking seams silly vs just doing your high octane map. I made a post on hp tuners but it's tumble weed in the toyota section. why not just change the base timing so it's not effected at all? I am just trying to find out the highest timing you can run on base by just plus 1 the whole chart or max on high ocatain with the base left alone ? i can find peak numbneers on lots of motor but not the 1grfe

    Let’s just say not everyone invests the time to do their own testing, find and read patents to understand how the operating system actually functions. The timing maps don't function like a typical LS, so doing "LS things" doesn't always yield the results you're looking for and can come with unintended consequences.

    for example my supra a 7mgte you do not go over 12 dagress on base safe is 8 dagress 10 is stock and then at peak is 12 to 15 including the base map when running big boost then once ya know the numbers it's on to the dyno tell ya see your torq drop and then back down ect ect ect
