    i hear ya, but i thought people were making a big deal about bringing the laptop? you can view graphs and edit on the AP w/o laptop?

    AP is nice in a pinch, but is no replacement for a laptop, being able to view the run on a graph right afterwards is awesome. Too bad I don't have an old tablet laptop where it was a touchscreen that flips around, that would be perfect and worth building some kind of mount for it.

    It appears based on this diagram that when this fuel mass valve (4) opens high pressure is able to push the plunger up allowing high pressure to bleed off back to the vacuum side of the high pressure pump (to position 2). What stops this pressure from pushing all the way back to the in tank pump?

    Not to be a smart ass, but is it #2? It seems to be the feed with a check valve to prevent backflow. Seems #2 and #9 are employed in a fashion to ensure that the pressurized fuel only flows forward.

    I mentioned this before even a really low frequency sampling into a circular buffer would be sweet, where is the JB4 Flight Recorder feature Click here to enlarge

I do know in car during deceleration it's running 100% duty cycle so if the DME is sinking current that means it's in the at rest position. At idle it's running around 75% (or 25% open). And at full throttle the lowest I've seen is 50% open.

    i assume 0% DC is limp mode allowing fuel to bypass the HPFP. Otherwise it regulates volume to the HPFP.

    It looks like all the feed travels through 5. I guess the basic question is can fluid go from 7 back towards 6. Looking at the solenoid in front of me I can't really tell but there is a pressure seal on the tip that makes it look like it may be sealing itself in 7.

    What's this little piece of trash labeled #8 (Supply passage, pressure limiting device)? That sounds like the fun police to me...
