10% ethanol's affect on afrs

[shift_down]

Has anyone noticed a difference in their afrs when using a 10% ethanol gas vs a pure gas on their turboed motors?

In europe we already have 10% ethanol in our regular gas. I suspect you do, too.

Anyway, it should lean out something like 0.5 to 1 AFR point, at most.

Ya, most of the stations in the US have 10% ethanol. Ok thatnks for that information. My car is a little on the lean side, so I'm going to see if 100% gas fixes it a little.

I'm thinking, nothing comes to mind. If 10% ethanol is making my car run slightly lean, 100% gas will richen it out a but. Right?

At idle and constant speed you got the AFR closed loop that kicks in and should give around 15:1 AFR though, which is perfectly normal. You need to be rich when accelerating and on high load, if you are already lean or just stoeich at these times, you got a fuel system issue (most of the time it is the fuel pump or its wiring). If your car is not stock and you did not have it mapped... get it mapped.
