Re: Base fuel pressure adjustments

I meant that the deadtimes affected it a lot at idle, often more than anything with huge injectors, I had just worded it poorly above.

Here is the formula to find injector flow with changes in base fuel pressure. Injectors are usually rated for 43.5psi.

SquareRoot(New Fuel Pressure / Old Fuel Pressure) * Old Injector Flow in CC = New Injector Flow in CC

SQRT(40psi/43.5psi)*1600cc=1534cc

1600/1534 = 4.3%
1534/1600 = 4.1%
