Oil pressure t444e

Anyone know what the desirable oil pressure is on these engines? My computer is reading oil pressure at about 55psi and as low as 35 when warmed up at idle. Do I have anything to worry about? No computer codes...

most 444E's when hot at idle read in the 20s.. navistar sets of the Oil pressure alarm if its below 8 PSI at idle for more than 10 seconds... full RPM Lube oil pressure when hot (by hot I mean 195 oil temp) is typically in the low-mid 40s.. but they can run Ok in the high 30s.. I think 30 is the oil pressure alarm for above 2000 RPM..



your computer has it in the parameters in servicemaxx as to what the alarms are set at.. yours sounds like its running great oil P's

Thanks Christopher! I switched over to the Bluefire digital gauges and I'm in the yellow (verses the red or green, according to their stock settings) at 35 psi so I wanted to make sure it was okay. Dude ... I LOVE these gauges.

bluefire makes hard gauges that run off J1708? I always thought they were standard sender gauges or you used their app.. im interested to know more

it's a bluetooth sender ... they recently designed a gui dashboard that I pull up on my tablet. I tore the old cluster out and exclusively use that now. Tablet boots right up into the app.

got it! so you are using the app.. nice! I have my old cluster. and my tablets are up high.. on my bus the original cluster is nearly unviewable anyway.. and will be more-so if i have A/C vents and duct in the areas under the defroster ducts..



is the layout and styles on that app editable or is it fixed? also interested to know if it reads HPOP data.. my VMSpc doesnt (I know the data is sent I see it in the raw strings..)

Sounds higher than the oil pressures I've had on any of my buses. Kudos to you!

App is editable... you can change the size and position of the gauges. I believe he's working on adding color schemes too. If you email them they'll add the hpop data (I too can see it from the servicemaxx software) in a couple days. So far great customer service and response times. Actually you can download the bluefire for trucks mode and use it in demo mode to see how it works, without the hardware.

super!! HPOP is PID 164. where these porograms die it seems is multiple PID's in one frame. the J1587 spec allows it but like my VMSpc doesnt see it, I verified it was there when I wrote my own app to read and show the J1587 data.. I parsed the multi-frames..

What are these BlueFire gauges you speak of? I'm intrigued.
