I was wondering about closed loop mode. If I set the injector pulse width for a lean condition then the ECU based on O2 input will try to compensate?

I can disable closed loop mode. But I would need to have my maps dead on. I've also been reading that lean AFR's should have more spark to ignite. Also higher compression helps. However, melting pistons is possible since the piston tops are not as strong as a diesel. Diesel engines run as lean as 100:1 at idle.

he, he, he... how about use some diesel pistons in a gas block and make a stroked motor with high compression? Or, use a diesel block with a gasser head! That would be easy.

I know that a Crane Hi-8 CDI box can fire a plug multiple times at the compression stroke. I bet many of the performance modes would help for a lean burn motor.
