I dont hang much on this site, suppose I should frequent it more here -- But ForScan, at least the PC version can operate the turbo vanes -- you can operate from 0 to 99 -- at the 99 to 100% value the turbo swings from closed to open(bug in ForScan I think) - this is handy to see/feel the workings of the turbo vanes, because moving the control just one point completely swings the turbo -- and the EBP an MAP sensors, since the air system can be easily pressurized with the turbo
The "normal" working range for the turbo is 15open to 85% closed -- but ForScan will swing the turbo all the way to 99% -- there is a definite difference in engine load from 85 to 99% -- I am thinking this could be used as an engine brake, but was not implemented by Ford
You might as well pull the EBP sensor and verify it is clean and the tube is clear.
Any way to know if you have the updated dummy plugs and standpipes before you tear into it? Same question for the HPOP discharge fitting?
Tomorrow I will look at the EBP sensor, and no I have no idea. As far as I know they are orginal. The guy I bought the truck from was the original owner, all he told me was he did the EGR delete and Coolant Filter at 10k miles. Other then that he had not done a thing minus wear item . Brakes etc... he did change the oil every 3k miles.
After thinking a bit, the EBP is "supposed" to be in psia units according to the PC/ED manual. As such it should read the same as barometric pressure at KOEO.
His KOEO EBP reading is 0 instead of 14.2 psia. I know the Edge does some funny things w/ the EBP value and I had thought that one of the odd things was that it reported the value in gauge pressure (and if so, the "0" reading would be good at KOEO). What if his CTS2 is actually reading the EBP in psia as it should and it is reporting it as zero? Doesn't make sense to me to do that, especially since he sees actual EBP values when the engine is running - but I was just doing a "what if" moment.
Yall are getting real technical on me here haha. But hopefully on monday when I get it hooked up to the scan tool I can get you guys some better reading. If there is anything specifically that I need to be looking for or that you guys with more knowledge then me would like to see let me know and I will make sure to get you the numbers.
So this afternoon I will be doing my Air test. However I drove the truck this morning about 20 miles and it did run really well the whole time. I got some numbers I would like to share with you all.
Just off the top of the head all that looks not too bad. Except, if you were WOT of any lenght of time the boost is low, the VGT% is too high And EBP again is off. If you were under hard acceleration the boost should be above 20psi the vgt maybe in the mid to high 30's and EBP30+ or so.
What happened to the ICP pressure you could not get more than 1000 or so at 85% now nearly 3000 at 64 % IPR, bap pumps and leaks don't usually fix themselves? You might find that the air test is a waste of time. Is is hard to find things when they are not broke. Maybe hold up on the test and save that for later ? Right now you do have a problem that is "broke" and should not be too hard to fix. The EBP needs to get sorted;. Besides wiring, which you can look at later, try to post EBP voltage say at KOEO and KOER. I don't think the 15 degree negative bias would be caused by a clogged tube leading the the sensor. Save the cleaning out the tube for later. I would guess that the either the sensor is bad or the two wires that go from the sensor to be PCM are comprised. Testing that is a little more complicated. you will need to ohm check them for continuity and short to ground or power. I don't have a wiring diagram for an 05 put I can post the pin numbers for an 03, later.
ps, did you have any part of the oil system apart before you got the code of low pressure ICP?

No I didnt have anything apart what so ever. Only thing done recently was the oil change and fuel filter changes. My egr delete hose(little blue hose) was leaking and I fixed that. That was a while back though. I dont truly know when I got the code bc my check engine light never came on.... and I will get you those numbers you requested shortly.
All the EBP numbers seem to me to be consistent with the CTS2 reporting it in gauge pressure, not absolute (ie when you add 14.2 to all the EBP readings, they then look reasonable as compared to the boost number). For now I am inclined to assume that Edge scan tools just manage the EBP reading in their own special way!
Interesting that the high pressure oil pressure looks a whole lot better now (unless you were trying for WOT as knotreel pointed out).
Definitely agree that the VGT number is still a little off.

I was not trying for WOT I was simply merging on the interstate. If need be I can do another WOT test a little bit late . I will post some more KOEO and KOER numbers from my edge here in a little bit. My buddy is still bring home his scanner today so I will take the truck over there and hook it to the scan tool as well to get reading from a different type of monitor. What should I have him look for? Anything different than what the edge will show?

KOEO KOER
So the EBP voltage is that somethi g I have to check at the sensor with a meter? Bc I dont see that as an option on my edge PID's
I think bismic has a good point, I know my AutoEnginuity diagoniscis gave me fits until Bismic advised forscan. As for EBP, maybe it's not an issue. As for the VGT, I know on mine it takes awhile under hard Accel (WOT) for in to lower into the 30's.. Maybe all is right?
Maybe a WOT view of your Edge in the 2000-3000 range might make all this look right? Mosly it would be good to see the ICP at at least 3500psi or at least see what it can do WOT at 85%.
Not sure how applicable since I am tuned, but here is a table of my VGT numbers I recorded a while back.
Hey Mark,
Are there additional values like this posted in the Tech folders? I've been looking to create a spreadsheet that shows all kinds of info are varies states (idle, coast, WOT, ect.). I'm getting to know "my" numbers but I couldn't necessarily say if they are in acceptable ranges.
1st pic is movin. 80- 85. 2nd back home idle. 3rd is just fired up. Don't know if it will help. But my truck runs great. I know the order is whacked. Took multiple pics and had to sort.
