The fuel right out of the tank, especially when you got your "dongle' to work . Was able to successfully pair a 10 dollar one to my phone..THANK GOD. Any chance i had, i was "put'n the hammer down, harry'...to see if numbers increased/decreased..

Now, i'll post adequate numbers tomorrow morning, but i swear, iwas seeing 36xxpsi in ICP, and 55.16% d.c.? Can this bee possible? I've looked around, and found a saying that a stock hpop will not see more than 2900psi, and that if something was bad..ipr, icp, hpop...it would be low icp and high ipr d.c...??? (new ipr and icp within last 2yrs. No oil in plug either)

MAP, i was at 13.79(cold) idle, 14.5 idle closer i was to the beach with engine warm. WOT runs, saw tops 26.xx....??

Ears are open guys.

 

Pardon my ignorance, but what are you trying to say?

 

It is a different language, aint it? He is using an application for a smart phone called Torque Pro, I believe. The dongle is a device that plugs into a receptacle hidden under the dash by the steering column. The dongle acts as a transmitter/receiver between the smart phone (in this case) and the communications buss in the truck. It enables you to read many different data points available on the buss from the IDM, PCM, etc. Torque Pro is available (I beleive) only for Android phones at this time, not I-Phones.
You can search out all of the acronyms on this forum, there is a list of the acronyms which someone will no doubt refer you to. These acronyms talk about what is happening in the engine/transmission at a given moment. HPOP is a high pressure oil pump. The PCM (power control module) can control how much fuel is injected at a given moment by 1) adjusting the oil pressure from the HPOP to drive the injectors with more or less force, 2) adjusting the length of time (pulse width) that the high oil pressure is applied to the injector (this is an electrical signal -115 volts dc). The timing of the injection event is also controlled.
The 7.3 and 6.0 diesels use hydraulically powered, electrically controlled injectors unlike newer engines that use only electrically powered and controlled injectors. Many older diesels use injectors that are fed by a high pressure fuel pump that controls the amount of fuel, the fuel pressure, and the timing.
I left out lots of information, because I don't know much, but others will chime in, I am sure!

Set your Torque to record all your monitored parameters, then we can graph the data.

To answer a couple of questions - the stock HPOP can go really high, but under the right (or wrong) circumstances. 3600 PSI ICP and 55% IPR leads me to believe you had a Stinky Spike, but only a log would verify that.

26 PSI max MAP at WOT? I'd be curious about the EBP - but you may have a big leak or some turbo damage.

 

Thanks Tug.

About the icp, it will hover/stay dormant at that number and never fall. D.C. will "spike" at the blip of the throttle, and continue to rise to that number then flatlines at the 55%mark until i lift the pedal...everytime.

I'm running the Car Gauge Pro, and cannot find the EBP parameter. Turbo rebuilt 4yrs ago, and tried a purchased/rebuilt turbo as well, hunting for loss boost. Still same outcome. EBP and tube, replaced about 2yrs ago...(turbo feels/spins good)

Not ruling boost leak out, but did just install cac boots off IC and didnt change #'s/performance. Only thing left to take a gander at is the plenums themselves and/or get my butt off couch and install the bellow uppies..(even though theres absolutly no soot on/around the coolector)...

Buzz test sounded "even". I found the CCT log, but will not record??

To enlighten the issue...turbo went 4+yrs ago, prior to that, truck would burnout in 2nd gear(going thru intersection), now, it wont even break loose with standing water, lol

 

Where did you get the PIDs from?

 

When I tried CGP, everything was in there - but I only tried a few things before it pi55ed me off.

 

ok..i'll go now and fire ur up. I'm under the "powertrain" tab. There is a "powertrain 2" tab as well, but it wouldnt pair to it. Maybe i did something wrong...wouldnt be the first. Also, i know what you mean about CGP being temperamental. Did the CCT run, wouldnt communicate and BAM, truck wouldnt kick back over, lol...

 

alright, didnt fireup truck to get readings but just KOEO setting, can not find the EBP tab. Is it labeled under something different..i.e. egr..etc Thanks.

 

I can't remember, it was so long ago. Sorry. I'm not about to load it back up to find out... I already met my lifetime exposure limit to "appstration" with that one.

 

no worries Tug, appreciate the help . WIth limited use of CGP from members, i installed T.P. on wifes' phone, but want to have T.P. as well. With that said, is it as easy has..buying a cheap tablet, downloading T.P. and pairing up with bluetooth, and be able to drive around? OR, will i need some type of device(phone) to enable wifi to the tablet, for it to work correctly..(connect to dongle)...

 

Torque Pro doesn't need outside data to run if that's what you're asking. It just bluetooths with the dongle and you're set. I got a cheap tablet and did like you are talking about. Unfortunately I also got a cheap Bluetooth from China, POS.

 

Torque Pro has a feature where you can share. I haven't used it yet, so I don't know if it's sharing the BT, forwarding the BT out via WiFi, sharing the data, or what... but it has it.

 

Sounds pretty normal to me. Duty cycle is a worry when hitting the 60's so 55 is fine. If you are WOT at higher RPM a sudden lift of the go pedal will spike the ICP as all the demanded oil suddenly rushing to the 8 exits has the door snap shut. I see a brief 3300psi under those conditions, and I chalk that up to known o-ring leakage. So 3600 is within the realm of normal. I read on the internet the system can take up to 5000 before things start blowing out.


Try building a leak down detector?

 

Thanks for the responses, idear'rs and answered questions

Will let my itchy finger blast away on my pee-shooter buckzooka . Biglots gots a cheapo here for 50 bones

Leakdown detector? Think im pick'n up what ur throw'n down, but where to connect to...plug at hpop?

Alrighty...winning numbers are...(drumroll)

ICP/wot = 3851.11..flatlines
IPR/wot = 55.4%..flatline
......flatlines until lift on go pedal

ICP/idle = 608.11
IPR/idle = 26%
...not continuous, but every soooo often until i think, when temps are normal, i get a quick stumble on ICP..405.xx psi, then quickly back to 608.11. IPR has a .xx diference

MAP/wot = 27.xx
MAP/idle 13.78
