93 octane vs E85 on a BMW E46 M3
“I used to tune cars for E85 for a living, but my tunes were always off in the real world because E85 at the pump is never a consistent percentage of ethanol. That’s when I invented the PROFLEX Commander. E85 tunes are insufficient and now obsolete. This is the best way you can run E85 and always make maximum power safely.”
