Differences in AFR and timing requirements between E10 and MTBE
Like the title says, what kind of differences can I expect? Here in NJ, we seem to have both E10 and standard with MTBE. IIRC they dont require the complete phase-out of MTBE until 2009 here.
Whats the stoich AFR with MTBE? Low 14's? Ive set the calibration up to run with a stoich AFR of 14.1:1, and the EFI is precise enough to track along the desired AFR to within +/- 2% across the board, but its stort of wasted if each tank of fuel has a different AFR requirement.
What about timing? Does E10 need a little more over standard gas with MTBE?
