COP, rx8 mode, ms2v3
i am curious what some people are using for their dwell settings on this type of setup? i am chasing some break up issues above 6500 rpm i logged a pull and i am seeing dwell as low as 2.0 ms. i am using GM ls2 coils. the current settings worked well when i was NA but now that i am boosted i am having issues. my AFR are a pinch rich around 11-10:1 in boost, after talking to some guys at the track who were running an 8second rx3 they recommended i tune closer to 12:1 until 15lbs. seems a pinch lean but i am not scared to try. the car will free rev to the rev limiter 8500rpm

I have tried 2 new sets of plugs. 14s and 9s. Same result. I data logged my battery voltage and it is @14+ across the board. I have my static dwell at 6ms and i am seeing 2ms around 7k rpm. Verified plug wires are helthy.
