How to get more resolution from ve table numbers mspnp2
I saw a post floating around here where someone was messing with the required fuel and multiplying the ve table numbers by a certain percentage to how much he changed the required fuel. It was confirmed by another well knowledgeable member here that his method was correct. What I would want to know is what is the formula for doing this? His application was non boosted so what would I need to do for a required fuel of 2.6 and a max kpa of 190. My highest ve number goes up to 111

3) Divide req fuel by multiplier, this will make req fuel smaller.
Since our equation now is:
PW = DT + (ReqFuel * [Multiplier] * MAP * VE[RPM,MAP] / [Multiplier] * AirDen * BaroCor * corrections)
So the * mult and / mult cancel out, we inject the same amount of fuel, but we have greater resolution in our VE table..?
