EBP question
Hi Guys. I'm a diesel dummy and got a question about my EBP readings from my Scangauge II.
2004 F350 drw SCLB 4x4 4.10 gears 5Rauto stock exhaust w/cat. 130K mi.
Truck runs great, deltas range 5-7 @ 65mph flat interstate no load.
At 74 mph on cruise, EBP ranges from 27-30. Cold start @ idle 13-16. Idle after 65 mi drive home from work 14-17. Are these ranges normal, a need for concern or a need for maintenance. Thanks in advance for your replies & input from a diesel dummy that is learning as I go.

Is there a relationship between map, bst, and ebp?
I'm thinking map (atmospheric) + bst is going to give a rough equivalent to ebp? I've watched all 3 on my SG2 just don't remember if there was anything obvious going on.. I might watch them along with vgt tonight to give myself something to do while driving home..

EBP
Most manuals I have read and systems I have datalogged pretty much coincide.
The PCM compares a number of values and their relationship with each other to determin how it will run.
Think of it as breathing in and out.
All sensors associated with air intake, Map; Maff; IAT1 and 2 and baro deal with the intake side. EBP deals with the exhaust side or how it breaths out..
Relative comparison of these sensors deternins how much boost [additional air} that may be needed to obtain optimal combustion conditions. The primary purpose of the whole shebang. LOL
