Logging fuel pump?
2013 5.0, I use a SCT Livewire. What PIDS do I want to log? I've logged Fuel Pump Duty Cycle, Fuel Pump Percentage, and Fuel Pump Module Duty Cycle. From what I understand Fuel Pump Duty Cycle maxes out at .50, so basically .50 = pump maxed out .5x2 = 1.00. At Wot on 93 I'm at .48 pump duty cycle, .87 pump percentage, and module duty cycle is at 60%. I know logging afr and trims is part of this, but just want to understand logging the actual pump. Thanks.
Can't log fuel pump on gen1 coyote.
None of those PID's will tell you if fuel pressure is dropping, which is what you actually want to see, just that the pump's duty cycle is high, which is completely normal.
