Hey FoPar, if you ran E98 instead of 85, would you end up with even less of a fuel requirement than the standard 98? I got to thinking and wondered if E98 had more energy value or is it just detonation threshhold?
what engine do u have in ur car? i was just looking at the 98 and E85 tunes at WOT and 21psi, 25% more E85 is used than. the E85 tune reads 11.4 AFR and the BP98 reads 12.2 AFR
