What AFR's do u run with W/I??

[Tony35]

I just wanted to get an insite on what everyones AFRs were. Im running between 11.3 when boost is around 16psi and like 11.7-12.0 when its at like 20psi. I dont have a knock detector so i know some of u do and will know when it starts to knock if it even does with W/I. I know people say its bad to tune with meth because if the pump goes out or what not ull be running really lean and hurt the engine. The thing is i figure that u can see those lean AFRs and not boost untill the situation is resolved. Im not trying to debate what AFRs are good i just want to know what everyones is running. Thank You for any information on your tune.

i just leave the fuel tune pretty mcuh where it is and boost it a little higher. reason is because the stoich for methanol is actually not even remotely close to the same as for gasoline, so if you are running a larger nozzle and injecting alot of meth, a leaner tune is not necessarliy better. the meth will help suppress knock, but since it has a different stoich and you are mixing the two "fuels" i would just leave it alone. just my 2 cents. just boost it up a couple pounds and it will put a smile on your face

stoich doesnt matter, if you using a wideband its reading O2 content(Lambda) so its doesnt care what fuel you have. It reads the same!

It definatley makes a difference. like when im running it at 11.3 the wheels just break loose but when its at like 11.7 the wheels are barley gripping and u can feel the pull.
