?Line Pr. PSI?
i've heard alot about the fpr mod and how and when to do it. so i was wondering if my edge evolution programmer would tell me what the current pressure is.
i plugged it in and went to the data stream option. it gives the current rpms, engine oil temp, transd fluid temp, exhaust back pressure, and line pr. PSI. i don't know if this refers to the the fuel pressure. does anyone know.
anyway cruising at 70mph the reading for this was around 30 and with the petal to the metal it reached 71 at the highest point.
on another note the exhuast back pressure never got over 28 psi. is this good?
any input would be good.

oh yeah sorry. You need to have the engine cranking or running., and Joe is right. two possible locations for the EBP sensor on the 97. Mine is the in the early 97 location.

I recently had to replace my steel hose for the BP sensor. Look in my pics in my sig for more info. It took several attempts to get the hose for the late '97's. they only used it 1/2 year.

Got a question on the fuel pressure check, is it better to hook the gauge up to it then start or when already running or does it matter?
Also I have used my gauge on a gas engine, is it ok to use on the diesel also?
Last question, for now anyways, can someone direct me to a good post with directions and maybe pictures of the fpr bb mod? Thanks for any help.
