Continuing to sort out my CIS system

[blpetry]

I installed a AFM gauge and it appears the engine maybe functioning correctly. At idle, 12.5- 13.5, cruising, 14.0 -15.9 and acceleration 12.8-13.5. Of course this is fluctuating rapidly. But in theory the CIS system and the O2 system are doing what they are supposed to?

On my 82 SC, my AEM wideband shows a steady 14.7 in closed loop (warm) idle, which is what CIS is designed to do. You're running rich and fouling plugs I bet. BTW BPR7ES is the correct plug for our motors.
