Got a question about datalogging fuel pressure with my Xcal2 if that is even possible? Where at in the datalog files would I choose to datalog it? I am curious because I just had Walbro Dual 255lph fuel pumps and 60# Injectors installed along with my KB 2.3 last week and want to see where it is at. Thanks, Jeff.

You cant. There is no rail pressure sensor for the computer.

You might see FRP in the PIDS, but its just an inferred value and will always stay at 39, so its useless.

A good fuel pressure gauge is a must on these trucks.

Hope this info helps,

Thanks JJ. I read a post on one of the SCT Forums and it stated something about datalogging it.

They must have been refering to a returnless system. Fuel pressure on an L is an assumed (although changeable) value.
