I know the formula for gasoline engine, mostly using MAF+VSS.

For diesel, MAF can not help, but using MAP, IAT, RPM and LOAD we can evaluate the MPG.

Anyone know the formula? I understand that LOAD for a diesel engine is based on current fuelflow / peak fuelflow @ sea level, but I miss something somewhere :-/
