The Forbidden Supra·
I thought I was being extra-safe by keeping my timing a little low... But I noticed if I turn my timing lower than about 16 degrees at peak torque (up to 22 psi) with race fuel, it appears to be knocking like crazy. I just checked my knock data with my AEM and it's going up to 4 volts even at 4000-4500 rpm! It looks pretty bad. Is it detonating b/c the timing is too low? Or are those just misfires? How dangerous is that? The last time I dynoed my car, I had the timing set even lower at first b/c I wanted to log some good knock data so I would have something to compare to, and the same thing happened. The car would barely even run at 13-14 degrees. It kept popping and didn't want to accelerate smoothly. My car loves timing it seems.
