Can you figure out mileage if you know the vehicle speed, rpms, fuel
pressure and injector pulsewidths? This way I could figure out the best
cruise gear/rpms for my Camaro... Everyone's mentioned best cruise at
max torque, so should I be cruising at 3,000 rpm (off dynojet runs)? Do
I want the most vaccuum? If I go WOT at 3,000 rpm, my torque peaks at
475 ft-lbs, which propels me up to ludicrous speed in no time... I get
nervous cruising at more than 90 anyways... TIA!
