what wire? one tank of ethanol fuel is okay everyonce in awhile, just follow it with premium NO ethanol.

theres a black squar wire that goes to the cu that you unplugg when u run ethanol fuel it richens up the mapping about 10% but i wana lean it out a bit without a fuel box as i have been running 94 and have a barble occasionaly in the mid range but it clears out right away. just want to try runing some regular and see what it supposed to run like.

Stop running 94 and it'll probably go away. Mine doesn't even like 91! 87 is all it needs. Most M7's prefer the stock can & intake too.

I believe Shell has the lowest ethanol content, but don't quote me on that. It's always worked fine for me. :d

thats what i thought to because iw as running 92 esso marked and it wasnt as bad. so i was trying to find a station without ethanol but esso says theirs dont and shell 87 has up to 10% so i was thinking shell 89 with 5%
or do you run without the plug?
thanks again

Nope, it's plugged in and runs fine on Shell 87. EGT's never over 1100F. Stock intake, stock exhaust.

This is from the 2008 serivice manual, it says its ok to run fuel with ethanol.
