Steady AFR will smooth the car by a little bit and timing at shift will shave off the 1/4 time by a noticable 0.2-0.3s. WMI can run use pure ethanol or pure methnol depends on which one is the cheapest available too. Here's some 17deg vs 19deg BEF screenshots and you can see the mid end timing I'm talking about. It's peaking at same timing but mid end(after shift) is night and day difference. That's why I say 19deg would be a problem and 17 might be just fine.Thanks.
I never thought about WMI. Today I saw on map0, that I have some timing deviation 0.8-1.5. I'm not sure if it is some adaptation or spark plug problem, I'll observe it.
From things I read, it's not only about psi- people claim, that after BEF cars feel better and run faster even with a lower map.
I'll start with 17deg. Always I can mix fuel with 99% alcohol to clean logs- we don't have 85 here![]()
