Just wondering is my "HPOP pump" pressure looks right for 268k miles on oem injectors and
and
Hot shots stiction oil additives, work or not. did have a rough start last week when it was a bit cooler.. like a gasser with a missing spark plug or bad plug wire.. next morning cranked up and ran down road longer,, my usual drive for teh past couple month at harvest job is like 3 miles to shop to get truck for harvest stuff...have run motorcraft, delo, walmart oil more or less so thinking the striction oil addative could be good to help clean out the bit of slug that can build up over the years.
screen shot at 60 mph no trailer. Wot shows 2300 psi on hpop.
only driving 3 miles?
the engine Oil Temp has not even begun to get warm yet.
that is a good way to muck up a good engine, not letting it get warm before you take off fast.
when I have to go quick, I let it idle a minute or two, and then just put it in gear, and let it idle out of the driveway, and then take a side road and go about 20 mph until things get warm enough to push it harder....
Your map sensor is reading incorrectly also. It says minimum was 20.something. It should read 14.4ish at minimum like the ebp sensor. So it's 5-6 psi high.
so i guess the engine oil temp at 144 have not bearing on your comment. the outdoor air temp was around 63 or so when i started and this was couple mile later .. all i was asking does the HPOP pressure look decent for the rpm and speed.. as i mentioned the intake temp is not show correct.. it was NOT 39 degrees.. good job dumping your "tare" in the middle of the driveway..

This is extremely hard to give an opinion on in regards to hpop health, we have zero info on what tune, throttle input, pulse width, etc. just cruising along at low load is not the best way to determine the health of the hpop, or hpo system that it is supplying.
so what is better.. towing with load pulling hills?? during this run I did do a hard mash and saw 23-2400 psi pressure on pump.. but that was with so stuff in bed , level road, warm temps. etc.. truck runs fine when loaded and pull hills 5-6% grades no problem.. just wondering on age and miles on pump heath and not sure how to tell.. what is high pressure when load I should see?? tune was 80 hp DD tune and i run a 60 HP tow tune when pulling.. Tony Wildman 5 pos chip..
PS what is pulse width.. I don't see this on sensors in torque app..

Duty cycle is a good indicator on HPOP health. But the value depends on load, amount of go pedal applied and what not. Does it hold steady while under load?
pulse width is shown as IPW if I remember correctly
the only thing i could find was InjPW.. is that same as IPW
I see one what is [FORD] Fuel Injector Pulse Width, PID 221410.. is that the correct one.

Yes I believe that is the injector pulse width PID you're wanting. As for over all hpop health these simplest measuring stick, so to speak, is to monitor the IPR duty cycle % and the ICP during a moderate WOT pull. If there's long grade on your route that would be the spot I'd choose. Your stated WOT ICP of 2300 is on the low side but not by a lot, but what it the IPR DC% doing at that 2300 psi? If it's hanging out down in the mid to low 30's then that's all the PCM is asking for and everything is doing what it's told. If the DC% keeps climbing or pegs out the factory 64% or something like that then the PCM is asking for more but not getting it. Even still none of that is definitive of a bad pump. Those same symptoms can be caused by even the smallest of leaks in the system. At 2300 psi even a small leak is big. If you're having a long crank cold issue I would be checking the glow plug system before even thinking about pump problems. The batteries and cables would be high on my list too.
Thanks that what I was thinking on the IPW sensor.. I will take you number in mind when we start some long pulls.. I usually while watching EGT when it start to hit around 1200 and speed is around 55 mph I hit the OD button to down shift the trans to 3rd and run up the hill at around 2-2200 rpm no problem.. ;When i get on one of these i will check IPR and the IPW stuff to see..
as for cold starts today with temps around 40 deg, I let teh WTS light go off gave it a second, turned key counting one thousand one , one thousand two and it fires up and blow out a puff of black smoke like normal.. not sure it there is a problem just going off the miles and seeing like bitterroot say at 200K or so they might need to be rebuilt, replaced etc.. so do some don't i guess.
