General Discussion / Re: explanation of basic gauges ! importand
« on: August 01, 2012, 08:48:09 AM »
Makes me think I have the % engine load but have no idea what it really indicates. Since the % load goes as high as 100% but no higher even though the throttle is not fully on the floor what am I really looking at?

Need a somewhat technical explanation.


General Discussion / Ultragauge for KIA Optima SXL
« on: August 01, 2012, 08:40:53 AM »
Will the Ultragauge work on the 2013 Optima SXL? I have no idea if it is ODBII complaint and in any case don't know where the plug is located.

I have one on my 2012 Sprinter and use it all the time since there are so few gauges on that machine; just speedo, tach and fuel gauge (that's a laugh 10 bars in decreasing size). No oil pressure/temp, tranny pressure/oil pressure. Oh, it does have an ambient air temp readout.

In any  case I do want an Ultragauge for the Optima, which I assume is compatible.

Thanks, Robert

I wouldn't worry too much about it; when I ordered one they were supposed to be on back order for a month but I got mine within two weeks. They seem to be good folks.

General Discussion / Trouble codes UG to MB
« on: January 24, 2012, 07:42:44 AM »
2011 MB Sprinter 2500 w/3L? engine.

Last Wednesday while on a trip the check engine light came on while idling along side the road (problem with trucks brakes, not mine, the load drivers).

Turned the engine off and restarted, light still there. Checked codes (there were two which I didnít write down). No apparent loss of power and the next morning the light didnít come on. Checked the codes again and there was one pending P20B8.

Yesterday went to local MB dealer to check but they donít have any cross references to any other sources.

Is there, somewhere, a cross reference from the UG codes and other vehicle brands (specifically UG to MB)? Or can someone tell me what the UG code is in MB speak? What Iíd really like is UG to MB code reference for Sprinters.

VE is ignored on vehicles with MAF sensors.

So why did you suggest I enable it in an earlier post?

your sprinter has a maf

did you get the fuel economy calc to work?

Yes I did, unfortunately it didn't bring the average (or instantaneous) up any where near my calculated average. The calculated average is running just over 19MPG (over 6000 miles of fill ups) while the average MPG on the UG is about 10.8. The  (on the highway) runs from about 8 to 15 with the normal about 10 (16 to 21 down hill).

Oddly enough when I first start to decelerate the instantaneous goes way up but under continuous decel ( like long hills) the number starts to drop by a large amount.

The fuel economy calc was over a 20 mile stretch of winding, hilly roads ( I-84 in NY). They aint no straight roads in the north east.

The next time I get to PA going to or from a job on I-80 I'll try for a 200 mile calculation.

Haven't tried the VE enable yet as the UG ADMINISTRATOR suggest so will have to try that, I can always disable it if nothing changes for the better.

If you vehicle has a MAF sensor, then the VE is unimportant.  If you do not have a MAF sensor, then I would lean toward enabling the volumetric efficiency first.

Thanks again, I'll check for a MAF sensor first thing in the morning then go from there.

Thanks. I'm going to start tomorrow but one question; with a diesel engine (turbo charged) have to do the volumetric thingy first or just the mileage calibration? On the one hand the instruction say to do that first and on the other it says not to bother with diesel engines. So far the instructions (in some places) seem to be confusing.


Since you have a Diesel, you must calibrate it otherwise UG will be way off.  The calibration process is simple.  Just follow each step listed in the manual.

General Discussion / UG's average and instantaneous MPG way off

Got the scare of my life the other day. Iíd finally installed my UG and was testing it. Worked great.

Set the engine size and fuel tank capacity ( 3.0 L and 25 USG [BTW it is a 2011 2500 MB Sprinter high top 144 inch wheel base]) and when I left my bumpy gravel road and got onto pavement, up a 8% or 9% grade the instantaneous MPG read 1.5 or so, scared the bejesses out of me.

Out on the road on a 400 mile trip the average MPG got up to slightly over 8.6 while the instantaneous MPG ran from about 5.6 to 9.5 (or there abouts).

Now I keep meticulous fuel records so know that over the life (a whole 5900 miles) that the average MPG is slightly over 20 which doesnít jibe with the UG figures.

I have not yet ďcalibratedĒ UG yet but it seems to me those figures are a bit (lot) low. Obviously Iím going to have to get out on the road to do the calibrating but reading the instructions it seems extremely complicated. Added to that I live in Connecticut where there are no straight, flat roads and few mile markers. I will have to go over the border to New York and do a ten mile calibration and see if that works miracles.

So I ask is the calibration process going to bring UGís figures nearer to the calculated average MPG?

The $78.95 Ultra-Guage.

If it is OBDII compliant and it (should be) then yes. I just installed on in my 2011 Sprinter and it works great though with some odd readouts I'll mention in another thread.

Let's assume that there is an "oil quality" sensor.   Such a sensor might have an output range of 2V to 7V.  With 2V being good quality and 7V being the worst.   If the computer reads the sensor and finds a value of 10V, then you get a "Engine Oil Quality Sensor Circuit High"    Likewise if the computer read 0.5V, then it might output "Engine Oil Quality Sensor Circuit low".

Yikes! There is an "oil quality" sensor in all Mercedes Benz's according to my local MB service manager. Somehow it can tell the difference in viscosity from normal and tell if fuel or water is in the crank case.

I would avoid taking it to a shop.  They will just take your money and may or may no fix the problem.  Instead, purchase a factory shop manual.  Factory shop manuals are sold by the manufacturer.  Avoid the manuals found at the auto parts store.   A factory shop manual will have very detailed specific information and will cover the various sensors.   Buying factory manuals on-line is the way to go.  You can even find them on ebay.

Fortunately my Sprinter is still under warranty so won't cost me anything. Shop manual(s) sounds like a good idea but will have to wait for later.

Does it work on a Diesel Dodge (Mercides Benz) Sprinter van?

Sorry but what is the "it" you are talking about?

Engine Oil Quality Sensor Circuit High

Thanks, but what does that mean? I only have slightly over 5000 miles on it (bought it new).

How can "Oil Quality" be sensed/known by the ECM or whatever other computer is used, and what does it mean the circuit is high (voltage or current high)?

General Discussion / Trouble code question
« on: December 26, 2011, 10:40:13 AM »
2011 MB Sprinter 2500, 3.1v6.

After installing my UG I took the van out for a spin to check out the gauge and along the way began getting an alert that there was a pending trouble code, a bit later the check engine light came on.

At home I checked the code and found P252D which I cleared so light went out but it is still pending. What does P252D signify? Something with the power train but have been unable to find that code anywhere on the internet and believe me I've spent an hour or more searching sites that are supposed to give OBD-II codes with their meaning---no luck. Hope someone can help me before I spend money at the MB dealer in Danbury.

Problems solved. Plug was just extremely tight so it took extraordinary force to remove it but I got it done-no damage.

The other "problem" was "fixed" when I pushed the up button while the engine was running (should have read the instructions a little closer and I would have found those directions).

So all seems to be ok. I'll find out for sure on my next trip.

2011 Sprinter 3.1L diesel.

Installed my UG this morning, turned the engine on and set the UG up no problem.

Now for the problem. After setting it up (worked nicely) turned the engine off then to see how it works started the engine again and the UG was blank, no display.

Troubleshooting says possible fuse to the ODBII connector blown but voltage check shows 12+VDC at red wire in plug.

Troubleshooting also says to disconnect and try in another auto, and here's the problem, I can't disconnect the plug from the connector. I even removed the connector from the dash to see if I could see what was keeping the connector attached but no amount of light, prying with screwdriver or anything else did anything to help remove the plug (it is loose, wobbles when moved but refuses to come out [was that way before prying]).

Why would the UG work when first plugged in but not after restarting the engine? According to the directions it wasn't necessary to start the engine but neither do the directions indicate a potential problem if the engine was running. (It was freezing out was why I started the engine).


General Discussion / Recieved UG

Although the web page says the gauges will not be in stock until 12/27/11 I got mine yesterday 12/14/2011. Great service, thanks.

Printed the users manual this morning and will go over it later today, sort of "If all else fails....." before all else fails.

Looking forward to seeing how it works. I'm particularly interested in overall MPG and to a lesser extent instantaneous MPG. Other gauges will be added later.

As an Oversize load escort I put on anywhere from 3000 to over 5000 miles a month (the first week of escorting saw 2300 miles).

Have to find a place to put it, I have a 2011 MB Sprinter with a lot of stuff on the dash and don't know if I want to mount to the windshield or not. Can't put it over the steering column as it would obscure the readouts on the little screen. I'll find a place eventually.

General Discussion / Dead batteries
« on: December 09, 2011, 08:46:56 PM »
There has been a number of people who, after installing their UG's have had batteries go dead. I have doubts that it had anything to do with UG's. One of the major contributors to dead batteries is oxidization of the terminals. It is not always easy to tell if and how much there is as the outside of the connecting wire end looks clean, however when the terminal is removed the battery terminal is black. (Green fuzz is an obvious indication of course)

Over time ALL battery terminals become oxidized which results in the battery not being charged as it should (the oxidization produces resistance; that same resistance can cause difficulty starting the engine). If the battery is changed the problem goes away BUT may have wasted (often) a perfectly good battery.

So before deciding the battery is no good or the UG or any other consumer for that matter, ALWAYS CHECK THE TERMINALS FOR CORROSION (OXIDIZATION).

Mechanics are notorious for neglecting that simple maintenance item.


General Discussion / Re: Sprinter ODBII compliant
« on: December 07, 2011, 12:56:19 PM »
Ok. got the info from my loal MB dealer. The 2011 Sprinter is in fact ODBII compliant. The connector is supposed to be in the fuse box under the dash. Couldn't fine it before so will have to look closer.

Now I can order a UG.
