My Fuel pump voltage table has all cells at max 15.
Returnless Fuel Pump --> Fuel Pump Voltage Table
However I will point out even with the stock returnless settings the FPDM will still activate the relay. It's just not suited for continuous use while driving because if the duty cycle goes to low the relay could turn off.
From that link I posted earlier
"I believe you will have to change the Returnless fuel pump mode scalar value in the tune to 0, and make sure the Return Fuel duty cycle is set to a reasonable value (70% is shown below), to have this work properly."
In advantage the return fuel duty cycle is a .6999 in AMZ2 did you leave that alone or adjust it any?
