Anyone tune a/f ratios for ethanol gas
Was just curious if anybody changed their desired a/f ratios for todays gas that contains 10% ethanol? I think I will tune WOT to compensate for that a little bit.
Ethanol needs a/f ratio of 9:1, less air than gasoline. In theory you could lean out the WOT ratio more than the normal 12.8:1 target. I wonder if this is why some tuners say the LS1 runs best with WOT a/f of 13.1:1?
