I bet it won't : 12.5 - 12.8 is pretty good!
OK, I'm talking V8 engines, but I can't imagine that different engines are different about AFR. I also tuned it with water alone exactly in the same range as yours, then switched to 50% ethanol (same quantity) and had the feeling the car was running better. On the dyno I changed timing (from 17 to 23*) and AFR (up to 13.:1) but I saw no power difference, I guess there is an optimum. Please let us know about the result, Im curious!
