6.6 REQ_FUEL = 2429cc displacement, 750cc injectors, 12:1 A/F.
What is the significance of the A/F for the equation? Is it asking the highest, lowest, or average A/F I want to run or what? I don't get it, so I've generally put in 12:1 cause I know that its safe.
2K4Night,
I don't know if you ever got this straightened out, but I'm guessing not at this point. The AFR you entered into the Req_Fuel calculator is wrong, and will make it calculate a required fuel amount that is too rich unless you're using E85 or something?
The calculator wants to know the AFR ratio at stoichiometric for the fuel you are injecting. If that's gasoline, then you need to enter 14.7. To get your engine to run properly with the amount of safety you desire in your AFRs, you just tune your VE table appropriately.
By the way, I'm betting you've fouled your plugs pretty badly by now by injecting that much fuel. Put in a new set of plugs, correct your ReqFuel amount, and it will probably fire up pretty decently so you can begin to tune.
Good luck!
