First I want to give a BIG THANKS to Dan, Milwaukee1979f150 for being kind enough to hook up his AE and do this for me he even calibrated my speedo and its as close as it gets . He spent about 2 hours going threw my truck telling me things I didnt know and teaching me the entire time. Also did a buzz test, thats cool, I now know why its called a BUZZ test. Hell of a guy.. Reps sent as soon as he gets on

A few things jumped out at Dan that I need help figuring out and if I word it wrong sorry but Im new to AE first time seeing it in action (awesome)
My ICP pressure was holding around 700 at idol, Dan informed me that that is WAY too high. What would cause that?
Second is my hpop was around 2400 at 72% duty, Ive got a feeling the answer isnt going to be good...
Last thing is that my oil was aerotor and he also said that that can cause high duty % and less pressure. and its known to be that the oil pick up tube is cracked or the seal leaks.
Any help would be great and very much appreciated

 

Reps to him when he comes around

700psi at what duty cycle, and was this at a cold start, after warming it will usually settle in around 500.

Obviously this HPOP was in a tune, what tune? 2400 is not terrible depending on what is commanded in a high tune.

Yeah if your oil is getting aerated it is generally overfilled or getting air possibly in the pickup tube.

 

It was around 728-750 psi at HOT idle.

Before I knew about turner I check Fuel volume usage. I immediate notice it consume too much so I ask him he say it had DP turner. Turn to Stock it drop little.


I would say it hard for me to know if power loss cause 38" tires/3.73.

Only thing I am concern it PEG 72% duty and only provide 2400 max it was bounce from 2000-2400 psi.

Oil he use is 5w40 Shell roatillea SYNTH. My old 00 F350 with 225K miles hit 2400 psi with only 39-45% if I can remember. It stock everything expect junkyard computer that I suspect programmer.

 

Dan lives about an hour away from me or so, so the truck was plenty warm when I got there, I dont know what % on that, hopefully he jumps on and help fill in the blanks for us.
I was in 80economy at WOT.
Oil was 1500 miles old and at the full mark.
EDIT: Thanks for jumping in Dan. I should note that I run a set of 315/75-16 snow tires during the winter and I could tell there was a power loss between the first year I ran them and this last winter. Gears are up high on the top of the list, Im recovering from a 2 month lay off

 

Yes it wasn't that far more likely 30 mins if you use I75.

I ask him if fuel filter was black he say no. Reason I ask because I thought there oil leak in injector system cause loss pressure.

I am pretty sure it was 11% with 728-750 icp psi. It way HIGH than it should be. My f350 only do 8.75-9% with 450-480 ICP PSI.


Forgot to ask you did it use oil lately or any smoke out exhaust on cold start? Let check fuel filter to see if it isn't black. Just try save you $$ from throw parts and not able fix.

 

Yeah that is a high duty cycle for a warm engine, any chance you guys looked at EOT? Might have a biased sensor. It should be like Dan's at around 500psi with around 9%

 

It was 158oF but with weather we had almost like 80-90oF something with humidity.


When I notice 158oF I thought something fun it should be 200-220oF and he had aftermarket temp gauge that saying 165oF I thought something funny.

Check hose on radiator it was very HOT. My idea pop and told him put aftermarket temp sender's wire in hose to keep heat inside for accurate temp.

 

I change the fuel filter around 10K I used to change it at 5K until I got to know the truck and its been clean every time Ive changed it, nothing in the bottom of the fuel bowl either.
Nope doesnt use any oil for the most part maybe a quart in 5K miles.
If its chilly out on cold starts Ill get a little white smoke but clears up fast

 

First... I hope he recorded the data.

That idle ICP is a little high, but what was the ICP DC at idle? My ICP is about 575 PSI with the ICP Duty Cycle at 11 % and the RPM at about 675. The Throttle Position Sensor Volts could be one thing to look at, my voltage is 0.65 while sitting there... all lonely and stuff.

2400 WOT with the ICP DC at 72%? Excellent! The problem is not likely to be the pump or anything else in your truck... you have just stumbled into what others have learned with AE and a DP Tuner. There is something in the PCM that reacts to the tune and makes the FIPW go to 5ms (a bit wide). A wide PW is like opening a faucet too far and the pressure behind the faucet starts to drop. A drop in ICP pressure triggers the ICP DC to come up in an attempt to compensate. If you look at the run on a graph, the Duty cycle likely starts at about 50% and climbs through the run until you drop out of it. With a peak of 72% Duty Cycle, I'm guessing you're reaching about 80-85 MPH before you bail (just say it was on a closed track).

This PW issue is not uncommon and it is a work in progress, but it's not a serious issue. It's just not optimal. Remember - how much time do you spend at WOT?

AE settings for a proper WOT test: All sampling rates no more than 50ms and make sure the vehicle is good and warmed up. Keep the number of tested parameters to an absolute minimum - this gets you the best resolution (more detail) on the important stuff.

• Throttle Volts - Max 5
• FIPW - Max 6 ms
• ICP DC - %
• MPH - Max 100
• RPM - Max 3500
• ICP - Max 3500

With the high gearing some of these trucks have, we need to get up there on the speedo for elevated RPM in overdrive. Do your test in stock and your favorite tune, you'll learn something... as I did.

 

Clarify clear again

When it hit 2400 psi it was 60% Top speed will be 60-65 we did with overdrive off to prevent damage transmission. It was 2000 psi when Duty hit 72% that was really highest I see out 10 powerstroke 7.3l did.


Idle ICP was 728-750 psi with IPR duty 11%

 

I was in 80e and I got up to 70-75 mph. Tugly roughly 10 seconds at WOT. My SES light also comes on at WOT

 

Damage the transmission? Hard shift? I let fly in OD because OD is where the magic happens (great acceleration), but my tune is dialed to my transmission.

Ever since I put that T500 in, I have to be real ginger on the right foot to keep it out of overboost. 0-60 in 7 seconds, 0-70 in 10 seconds, 0-80 in 14 seconds - according to AE. Click the first link in my sig to see the gauges move.

 

So do I have anything to worry about with these numbers?

 

Your getting what I'm getting and everything has been great on my rig so far. There will always be room for improvement, but there's this whole diminishing returns thing. SES is supposed to come on. I didn't know that for the first 18 months because my MAP signal was grounded by the previous owner to stop the SES light. Unfortunately, this also inhibits some of the performance and economy. I snipped that short on the MAP signal and I get lightning in the dash and thunder out the tailpipe.
