I only made 3 changes when going from 93 octane to E85 on this car.
I tried to keep things as close as possible without changing too much on the vehicle to do a true comparison!
1) Changed the alternate injector size to accommodate the extra fueling demands from the E85.
2) Setup the ALT maps to turn on when the input is enabled AND to use the ALT injector size
NOTE: I did NOT turn up the boost pressure, the boost controller was left at the same exact setting as it was with pump gas.
When all was said and done I did add at most 1-2 degrees to the 8-15psi columns (peak timing was actually the same above 6500!), but this is not pictured in the graphs above .. the timing was exactly the same as the pump gas tune for this comparison.
