If you were to run 94 gas which here in calgary has ethanol, would you pick the 91 OTS map on 93 OTS map.
This is for stock M2 with just MPE. proTUNING Freaks |

94 Petro is great gas, I run a 13:1 compression coyote on it and the timing is very aggressive with 0 knock for pump gas and such high compression. I wish we got gas here with higher ethanol content - 10% maximum is the worst.
I tried various brands of 91 including Shell with 0 ethanol and had to dial timing WAY back. |

Funny just recently I had issues with rough running on full tank of shell v power 91. Car is still stock. Added 1/3 tank of husky 94 and it smoother out. I was told that 10% ethanol is ok for fuel pump but higher numbers like 30% will gum them up. |

Your results will obviously vary considering you're further west!
