Hypertech knock -can it update??
Hypertech is supposed to work with a 93 octane fuel so it should not knock because I only run 93. I know a professional tune is better and probably when I'm done with my car I will have Frost do a tune.
For now I just wanted to use Hypertech to lower the coolant temp which it did great.
I heard that Hypertech can update certain programmers and pull the timing a bit to reduce knock retard which I am getting a max of 2.9. Any insight into this is appreciated.
