If everything looks good, you should be able to run up to E60 with the Dorch Stg 1 in the summer for more timing advance & power, and E50 in the winter. Altho, I’ll drop to E30-35 in winter so cold start cranking isn’t as bad.
Changing bn Emixes during the year and pump gas on road trips is where the ethanol sensor and Multimap become very convenient. |
Great info thanks. I do not have any kind of ethanol sensor at the moment so it would have to be a manual calculation but I figure if I stay on my 93 octane tune for now no harm in bumping up the octane a bit without knowing the exact content %.
So the stock LPFP is fine handling Ethanol?
Looks like you are in Maryland, I am in the NOVA area, any stations you recommend for E85?
