The bare minimum I'm looking for in control is complete control over DFCO. I want the engine to PLUMMET as if it had run out of gas when letting off the throttle.
I built a map sensor modifier box. Doesn't seem to affect mileage one way or the other, but I have discovered something recently. If I increase the voltage it technically runs a bit richer and retards timing, hard to say for sure without other diagnostic aids. But with increased voltage it will fuel cut pretty much right away. Normally it is a rare occassion to get it to fuel cut.
