I would guess it would lean out much sooner if I upped the methanol mix. Don't think it really matters though, I was running near 15 degrees of timing in the mid-range on that E45 mix and nary a peep out of my knock sensors, so there is a bit of diminishing returns at play here. |
Hey guys.. What does it mean to lean out? Im fbo, g5 iso n i run 50/50 e85... Just curious
