My first actual test of lean burn at idle. I try outrageous Air to Fuel Ratios and insane timing. Spoiler: It only kinda works.
I demonstrate real closed loop timing at idle by measuring the Peak Pressure Point (PPP) with Ion Sensing. If I can get this working in boost it should add HP vs a conservative tune, and if I can get this working in cruise it should increase fuel economy.
I talk about the Mods currently on my turbo Rx8 as well as what other mods I’m developing and what to expect in the future.
My first attempt to process a combustion chamber ion signal to find perfect ignition timing. Needs a lot of work, but it’s a good proof of concept.
Today I’m bench testing an Ion Sensing circuit as well as a Ignition
coil and igniter. Eventually I hope to use this for real closed loop
