Scan gauge readings

Well Guys and Gals, my scan gauge II at idle is reading EBP 18.5, IPR 9.0, and ICP 525. Chris and I were discussing it after looking at his with the scan gauge II. He thinks mine might be low on the IPR and ICP and high on the EBP. I defer to the grand knowledge. Let me know if I need to worry about anything, or check anything.

PS: I am running a diablo predator tuner on 85E. Truck is running smooth, starts right up, accelerates fine. Just curiosity.

9.0 on IPR DC is a little low. I have seen 9.0-9.5 on other rigs though. Mine usually sits at 10 when warmed up.

ICP is a touch higher than usual of 480-500 psi. Nothing to sweat though.

What is your EBP with engine off? It should be right at 14.5 give or take, depends on elevation.

17.5 is the EBP. Chris and I Both are going tear into cleaning the EBP sensor and tube and try again.

Okay on the drive home, level ground running 70, rpm approx. 2k. EBPV sitting around 25, IPR sitting around 24, ICP sitting around 1550. Do these levels sound about right.

My EBP reads ~15 when off and ~16 at idle. What was your boost reading at that time?

I didn't see any mention of the new EBP reading after the cleaning (key on, engine off). I just had an EBP read high and replacing it bounced my MPG back where it belongs. It needs to match your MAP sensor reading. My EBP was at 16.8 (bad), now it's at 14.2 (good).

Thanks Tugly. Mine is running high as well. Chris and I are going to try and clean it up this weekend. After 200k, its the little things that work on the pocket book.

Ted, it sounds like you just need to "blow the soot outa it". Hopefully, she'll be all good afterwards.

ICP and IPR sound good. EBP sounds High. As Tugley said EBP and MAP should be within a pound of each other.

Okay, looks like I will be tearing into the EBP this weekend, if the weather holds out. Maybe it can all be cleaned out. Maybe I need a new sensor and tube. We shall see.

Well cleaned the tube out. The EBP reading dropped to 15.4 at KOEO. At idle it is at 16.3. Have a new sensor on order. Will install when it arrives.

Well this morning after receiving a new sensor, I figured that I would try cleaning the old sensor and wow that thing was full of soot. I cleaned it up and put it back on and the EBP reads 14.5 KOEO. Sits around 15 idling. I will keep the other sensor and change it out the next time or have it on hand in case someone else needs it.
