I don't understand why everyone is so worried about A/F ratios. They mean nothing, as no two engines need the exact same one to make the most power or to get the best fuel mileage. And you have to pick one over the other with most if not all of them, unless you also have a way of measuring load on the engine.
You guys that have dyno tuned very much know that a 13-7 A/F ratio will get you good mileage but won't get you good power. You need something in the 12.5-1 ratio to do that. If you dyno tune strictly for A/F ratio you're giving up something somewhere, which is why you don't want a unit that controls it to just one static A/F ratio. It's good to see a nice smooth A/F ratio line, but if it's at the wrong ratio for your engine you're losing the power you could potentially be getting.
If this thing truly looks at crankshaft acceleration or deflection and tunes it to get the most power, it would be the best thing out there. There would be no guessing as to what A/F ratio to tune it for, as it would just adjust fuel to whatever is needed for the most power. My concern is how it then compensates for cruise conditions, where max power isn't the best for max mileage. If it constantly tunes for max power then it can't run near the 13.7 to 14-1 A/F ratio you want for best mileage.
Am I missing something?
