Originally posted by Tired2 Say at 100% Duty cycle for an injector (or any constant value), will a 1:1 FPR keep the same amount of fuel flowing from -80kPa up to 80kPa? (Full Vac to 'full' boost)? If that is the case, does the stock FPR just not handle the kPa > 0 (pressures above atmospheric)? If I'm on track so far.... Can I simply use my Cartech 12:1 adjustable FPR and set it for 1:1, lock it down, and tune the motor with megasquirt?
What is your 'full' boost your talking about? 80kpa is still basically Vac. Anything above 102kpa is +positive boost pressure considering if your at sea level. And No the fpr flows more fuel the higher the pressure gets so it does not flow the same amount of fuel through 'vac to full boost'. And the stock fpr just holds the fuel pressure at 43.5psi. And I wouldnt use those adjustable fpr. Just get a good quality 1:1 fpr.
