First thing for me to consider is the required fuel calculation.

Density and AFR constants aquired from here http://www.wp-motorsport.co.uk/res/E85_uk.pdf

Desnity 0.79 g/cc

AFR 9.32 :1

The full required fuel calculation can be found here http://www.vems.hu/wiki/index.php?page=GenBoard%2FManual%2FConfig%2FInjectorOpening

For Petroleum this is expressed as.... req_fuel = D / N * 0.0012 / 14.7 / 0.755 / I * 60000 and gives us the familiar req_fuel = 6.49 * D / N / I

For E85 this is expressed as.... req_fuel = D / N * 0.0012 / 9.32 / 0.79 / I * 60000 and gives us req_fuel = 9.78 * D / N / I

Constants for calculating req_fuel are as follows

Petroleum.....6.49

E85...........9.78
