Tech Talk VMSpc and my oil temps

I Cant seem to figure out my oil temps..

When I am on flat ground it goes to 202-206 any slight grade and it clime's to 210 +

Once its up it doesnt drop down maybe a degree or two while driving.. If I stop naturally it goes down.

So here is my problem/question

see the pics.. Alarm/color change comes on at 200 degrees and goes back to green at 199. I seen 220 in the green and today I sen 205 in the green. What is the problem? programming? sensor? or the unexplained?

Also for giggles.. updated to the new version and my mileage goes up sporadically.. after I close and open back up it is fine.. new version glitch I guess.. back to the oil

The outside temps are in the mid 80's today and you can see the coolant temps.. but this oil thing is bothering me

Several threads on VMSpc, maybe this one will help.....

When Does Data Become Information, VMSpc

I recall that Roger wrote you can adjust the alarm colors, if you wish.

I have nothing much to offer you, being too new to the data collection.  But your temp experience on the oil is different than mine, I would be lower under the conditions you wrote about.  I do fluctuate around 199/200 green to yellow.  Highest I have seen is 208 and that only for a moment, usually 205 is highest.  Was pretty hot day, 96+ when I saw the 208, lasted about couple minutes.

David,

Adjust the high Yellow and High Red settings to what you want them to be.

The yellow should come on at about the upper end of what you normally see in your coach in everyday operation.  Every coach is a bit different so there is no perfect number but what you ware seeing is pretty normal.  The red should come on to let you know it is outside a normal operation range.

On the VMSpc Menu select Advanced and then Parameter Editor.  Scroll down to the Oil Temperature Gauge.

Set the High Yellow to what you want, in this case it is 206 degrees.  Set the High Red a bit higher, in this example it is at 212 degrees.  You want the Yellow to let you know you have reached the upper you want the Red to alert you that you should be doing something about it.

I attached a pdf file on editing VMSpc screens and setting parameters.

Let me know if you want some help.

Roger, part of my interest is in this pic.. how does the warning come on at 200 but at 220 it turns green again.. is 220 degrees ok?

I also see it do the same thing with the 205.. yellow then green then back to yellow..

Also I believe my temps are high but I have not had the data long enough to be sure..

When I first plugged in my VMSpc I never seen it hit over 200 degrees on baker grade in california coming home in 115 degree temps

but now I am seeing them. consistently. I think I might have a problem with the turbo so I will watch it and see what it does..

85 degrees outside and running 210 on the oil with a slight grade I would say is a little high. Just my opinion though

Turbo 11.9 but load showing 92%.  That a function of 5th gear?  When i am at such as turbo 28, load then in 90+ range as I recall.

David, check the high red setting,  it should be higher than the high yellow. 

I can't say what your oil temps mean or why.  I would ask a Cummins tech.  After my last oil change it seemed to me that my oil temps went up a bit.  Next one will be at Cummins.

Let me know what happens. I can always check in and have a look on-line.

Mike, I don't know why turbo is low and load is high.  None of these readings are simultaneous so a screen shot can be confusing.  If you are trying to track some specific readings then turn on data logging for the gauges you want to track and set the frequency you want.  You can download the logged data into a spreadsheet for more detailed analysis.

Part of problem is rpm, appears you could be in eco mode because at 92% load at 1024 rpm, your engine has a hard time building boost at that low an rpm. You are basicly overloading your engine because in it is well below the best torque range [1200 + rpm] and has trouble building much boost at that speed. With that type of load on engine, in 5th gear, it should have shifted down gears to increase engine rpm which will increase torque and horsepower, and of course increases oil pressure, [oil circulation speed] and water pump speed, [water circulation and oil cooling ability]

David,  Jcus has a good point. Econ mode or not at that engine load and speed you are at the very bottom of the 5th range.  Better to step on it a bit to force a down shift or do it manually.  Higher RPMs are good for just about everything under higher loads.

One of the benefits to having a VMSpc system is that these data and how they interact are pretty easy to see.  When you change the way you drive or shift or brake you can see the results.  We have done a lot of mountain driving in the last four years and seeing this in real time helps you learn to be a better operator.

Been working on this problem here and there..

I never use the ECO mode on the trans... Changed out the Turbo, took a while to relearn but seems to be  back to the hp ratings and adjusted finally... still running high oil temps (I feel anyways)..

After changing the turbo temps seemed to drop a few degrees but still are high (might be normal, might not.. not sure what normal is)

Where is the oil cooler? Part of the trans area or other side where the AC fan is? I am thinking of taking it out and draining it blowing it out to see if something is stuck in it.. anything else I should look at? Again the new turbo seems to have helped... trip to Grand Canyon temps hit 220 on the oil.... pulled over and let it rest for a bit and it hung around 215 or so.. A lot of uphill climbing.

Ideas?

David,
It should be hid up behind the engine coolant filter. Below and behind the alternator.

David, 220° oil temps seem high to me.  Cummins can tell you if that is OK, not sure.  The highest oil temp I have ever seen is under 210, maybe 208 and not for long.  199-201 is typical. 

Every engine is going to be a bit different.  Your temp sender might be calibrated a bit different.  The important thing is to know what is typical for your engine and watch for variations outside of an expected range.  The high yellow and high red indicators can be set for every gauge based on your experience and expectations.

Eco mode on the transmission changes the shift points.  Upshifts a bit sooner, downshifts a bit later.  It seems to work best on relatively flat roads, lots of up and down hills or in the mountains probably not as well.  Try it out and see how it works for you.

David my 99  320 is on passenger side about even with bottom of radiator and about half way between engine and radiator. It is round and about 30 inches long with water hose in each end and oil hoses through side

Chris,

You are describing the trans. cooler. 

@ David,
Which are you hunting the oil cooler or the trans cooler?

David,

With the version of the M-11 you have it still should be hid behind the alternator and in front of the coolant filter on drivers side as the engine is setting in the coach. This is one thing that is almost impossible to get to to replace the "O" rings as the framerail is in the way.  Remember I said "almost" it can be removed without cutting the fraim rail or pulling the engine.

This link should show a diagram of the drivers side of an ISM motor. Though it is not labeled the oil cooler is above the oil filter and below the turbo. It is cylindrical and has coolant connections at the front and two lube ports at the bottom.

My ISM oil temp. runs about 205 degrees in normal operation.

On my 2003 U320 40' 2 slide, towing Honda Fit, "normal" oil temp in "normal" weather is 203 degrees.

I have yellow "alarm" set for 210, red for 220.

This past week we have been driving in 100 degree plus temperatures. My yellow warning light came on several times in climbing hills. 211 to 214 degrees max.  Took a while to come back down once the road leveled out.  With temps at 100 weather, sun beating on pavement, the roads are HOT! 

Side note: Never seen so many big rigs and even cars on the side of the road with shredded tires before this week. (I 10 between Tucson and now just west of San Antonio TX).  The most road "alligators" (shredded tire pieces) I have ever seen in my entire life were between El Paso and here just west of San Antonio. Makes me happy I did new tires a couple of months ago and use tire pressure sensors.

My latest yellow and red warning light settings I selected on VMSPC:

oil temp 210/220  (saw yellow this past week a couple times climbing in 100 plus ambient)
coolant temp 200/210 (saw yellow this past week a couple times climbing in 100 plus ambient)

Trans temps 220/240 (no occurrence yet that I recall)
retarder temp 235/275 (routinely see yellow on long steep downhills even using judiciously and intermittently as needed).  More common this week even on hills with the high road temps

NOTE: the above numbers are only my parameter settings in VMSPC for yellow and red warning lights on the laptop screen).
