Anyone tried to play with "Fuel System Voltage Min"?
Thesedays before I swap my Whipple to 2650, the main concern is "Fuel". So, I am playing with hptuners, and having some questions. Anyone tried to play with "Fuel System Voltage Min" in the pic attached? Can I put the higher numbers like 17.6V and does it work? Seems 17.6V is unrealistic if there is no voltage booster in my car. Is it working or just throwing some DTC? Actually, ZL1 has the higher number like the below. |

Yes, most of us running forced induction have cranked up those values to at least the ZL1 setting of 15.5V.
Not sure if anyone has gone higher?

Instead, I have the dropoff of max desired fuel pressure reduced progressively with higher flow rates in the FSCM (Fuel System > Pressure > Maximum).

There is a thread floating around here were we recently discussed this. Yes most FI guys have tuned those tables along with some adjustments to the switches below that tab. 15.5 volts is what mine is set at. I dont run it any higher since I have the JMS. On my brothers Z06(stock fuel system with no JMS) going higher then 16.5volts resulted in less low side PSI.
