So I was thinking, I lose lean burn when I plug in an Arduino which tells the computer the hybrid battery is empty. One way to solve this is to tell the car the battery is not in fact empty, as long as I'm moving at more than ~22mph (otherwise I'd get auto-stop with no IMA, which is very bad when driving around town), and to have it switch over to saying the battery is empty when I get below a certain speed so as to prevent auto-stop. I tried this for a while and while it works, it doesn't work all that well.
However, the IMA system also disables auto-stop under two other conditions: when outside air is below 40F, and when the climate control is set to "auto". I'm thinking I might feed the computer a 50% battery signal all the time and disable auto-stop by either telling the computer it's cold outside, or by figuring out what signal the climate control sends to keep auto-stop off. I suspect it's actually just going to require cutting a wire.
