Part of the reason I'm doing this is to work out lean burn on a rotary. I previously tried lean burn by adjusting the MAF sensor voltage until the throttle was wide open and power started dropping off. The biggest problem was that I had no way of controlling timing, and a lot of energy was wasted out the exhaust with higher EGTs.
With this I hope to have enough control to run >20:1 AFR with proper timing and get some solid data. My end goal is 40MPG+ cruise, and then to implement a control strategy to bring me into and out of lean burn smoothly.
