Fuel Pump Monitor Duty Cycle Questions

[xfrosty63x]

I was datalogging with my Predator tonight for the first time on the way to a car show, and I noticed a problem with my Fuel Pump Monitor. The reading for the FP M (Fuel Pump Monitor Duty Cycle) bounces back and forth between 88% to 100% to 114% and then back down again every few seconds. The FPM (Fuel Pump Monitor) switches back and forth from On to Off nearly every second.

Anyone know what this means exactly? How do I go about fixing this? First the IAC Valve tonight, and now this.

why log this??? wouldn't you be better using FP (Fuel pump duty cycle)

with the predator you have to multiply by 2... so if it shows 45 X 2 = 90%

The FP was fine. Showing between 32% and 38%.

I was looking through all parameters since I had time to kill on the road. Boyfriend was driving since I was holding my dog in my lap, so I wanted to watch everything and see what was going on.

Sorry for a bit offtopic, but how do you datalog Fuel pump duty cycle? I have predator as well, do you go to real life time data and then fuel? Also when you're done datalog how do you view it?

Anyone have any new thoughts?
