Learn me on Fuel pump duty cycle

[theunseenclass]

There are 2 different PID's for reading FPDC. the one your using you have to multiply by 2 so im pretty sure your maxed out.

My car is hitting what seems like a rev limit or fuel cut right around 5000rpm as well, I just got my Diablo Predator and logged my FPDC and it seems to max at 50.000% so I'm guessing my fuel pumps are fine, what else can I do? If my fuel filter was clogged, wouldn't my FPDC be way up? Plugs are fresh TR6's gapped at .034. Tried it with the stock tune and the diablo tune and it still does it??

Log your fuel pressure,

Datalog fuel injector d/p - there is no obd absolute or gage fuel pressure sensor, the frps measures differential pressure between the rail and manifold. Also log actual fuel pump voltage, the lookup table voltage, stft's, ltft's, maf counts, load, relative throttle position, batt voltage, ect, iat, iat2, both bank upstream o2 sensors off the top of my head.

And just how does one do this? My Predator can only datalog certain parameters and pump voltage, and lookup table voltage are not on the list.
