After reading my post I realized that I didn't post the reason behind all this.

What my goal is to make this a GCI engine at higher boost while running an A/F ratio of 14.7:1. I knew that my PC center electrode would light off before ignition spark with the hot #1 pre-chamber. The amount of knock in this case only 1.8 count is minimal and won't need a major jump in pre-chamber plug temp or leaner A/F ratio without coil ignition. My goal is to be able to tune with a certain amount of boost/load that will trigger an ignition shut off and go into GCI mode. The reason I want GCI mode is to give each cylinder its optimum combustion starting point that is based on load, A/F and combustion temperature before it starts auto compression ignition. This will give me individual ignition based on load, temperature and effective compression. The effective compression by my calculations is around 20:1 at this boost level of 36psi.
