Auto Enginuity Findings...
Hey guys,I got my Auto Enginuity in this week(thanks Clay),anyway,I figured out how to record and playback about the time my laptop went dead,but on my last run(I cant post it right now) and at WOT I was seeing ICP at about 1880ish and DC was in the 67 to 72% range....Please feel free to discuss while my laptop charges so I can go record a run and post it up...Thanks...Phil

Duty cycle is what the PCM is requesting. Basically, it is closing the IPR to build pressure. The higher the DC the more the IPR is closed. If you are only seeing 1880 psi, it could be related to several things. If you have a weak HPOP that could be one thing. Looks like you have original sticks, so it shouldnt be too much for the HPOP to supply.
Try a few more runs and see if it repeats. WOT runs take quite a bit of oil and you really need to make sure you hold it there for a few seconds to allow everything to catch up to it. Could also be a bad ICP sensor too!

If I'm reading the graph correctly the ICP spikes and starts to drop right when I nail it,it also spikes right when I let off,it also seems to peak out as far as usable ICP at about 1800ish at a gear change,someone please stop me if I'm off on my thinking...lol
So is this an HPOP issue or more likely something else,if it means anything the rotational velocity was at zero across all cylinders at idle(black CPS from Riffraff).

Alright you 2. Ya'll are sooooo ganging up on me so Phil will spend more of our precious hard earned money leaving me less to spend. My pocket book is feeling very very very light these days. But I guess I will forgive you guys just this once.

That sounds just like what you kept saying at RRE last year. Please tell me y'all are coming again this year.

So hopefully everyone has been able to view the graph,everyone think from that info it would be the HPOP and not say the IPR,or ICP maybe. At idle the ICP is in the 600 ish range,it starts pretty quick,it seems it could start a little quicker but my starter is still the stocker so I'm sure it's getting tired too.I want to order the T-500 but I'd like to know with some certainty that it's the culprit...Thanks

Wow...I'm sure you know more than I,but that's a vague/broad statement right? I know a set of singles will probably out perform a set of stock sticks,and I also know stock injectors have a bigger appetite for oil but to just simply say "your issue is AD injectors" isn't very productive is it?...

Sorry to be a stick in the mud, but from watching data on far more trucks than I can count, the biggest issue comes when the tuning commands more than about 3.2-3.5mS worth of injector pulse width on AD injectors while trying to maintain 2800+ PSI.
It's kind of complicated to explain, but the stock tuning commands about 3.2mS at 1600 PSI under full load (if the desired pressure is only 1600 PSI). The pulse width goes up when the pressure goes down. It's all an effort made by the PCM to maintain a specific "Mass Fuel Desired".
I can guarantee to you that your 80E program is calling for far more than that.
The ONLY way to diagnose a weak high pressure oil system is in the STOCK tune. What aftermarket tuning companies do after that throws a huge wrench in the gears.

OK I hear ya there,I just got AE this week and today was my first chance to play. My thinking was to run an HPOP check in one of my tunes since I'm running tunes while towing,so I thought the tax would show up better if there was an issue with the HPOP and such...

The tuning can skew results. As a tuner can demand more icp or less then stock. So if they only call for 2800 psi and your pump will carry 3000 without an issue your only going to get 2800 psi with a low ipr % because it can dump some oil back to the motor. But if you call for 3500 the ipr % is going to go up. With no change in pump just tunes can make it seem that your pump is weak. And that is just one parameter. Cleatus can go in to a LOT more detail then I can even begin to explain.
