I have been using mine for years and really only keep it on MPG, VOLTS, TRANSMISSION TEMP and COOLANT TEMP. I did have it on RPMs for a while but saw no use. My 03 has no tach either. I don't like the distraction of changing gauges either. Do any of you use some of the other gauges to achieve better MPG and how?

Using it on a DP with a Cat C7 and Allison, I watch the:Oil PressureTrans TempAir Intake TempEngine TempWe're usually out west in the mountains so I'm watching for any rising temps. You may wonder about the air intake temps. If the outside air temp goes up while you're pulling steep grades, the engine temps will usually rise also in a little while.When I had an alternator going bad I watched the voltage output - it was fluctuating a lot.Bill

Monitor GPH, which is fuel consumption, instantaneous. All you need to know. Look at your MPH on the dash gauge, and divide by GPH and you'll know your intantaneous MPG.I monitor all kinds of different parameters on my TDI... Turbo boost pressure, Exhaust Gas Temperature, Diesel Particulate Filter temperature, and Soot Load % in my DPF, which tells me when a DPF regeneration burnoff is about to, or is occuring, usually close to 90 to 95% when it cooks off the carbon, EGT's and DPF temp hit 1200F, you don't want to stop driving with that kind of heat up against the firewall, need to keep air circulating under the hood for a good 5 to 10 minutes afterwards to get rid of the heat soak surrounding the turbocharger and bearings, so the oil doesn't burn and coke in there... no synthetic motor oil can withstand that kind of heat, without burning up, so you drive until the regen is over 5 to 10 minutes, keep the air from motion moving over the extremely heated up parts.

When I am driving, I watch the road. Keeping an eye on a plethora of gauges, then calculating what is different and what is normal for EACH gauge is distracting. You know, you could even get your cell phone and record the gauges while driving. Just add to the distractions!

These are the ones I watch with my Scan Gauge.Oil PressureTrans TempEngine TempBoostThe first three I watch very carefully.I suspect if one of the first three were to get out of hand and you did not do something about it then you will have plenty of time to watch the road while waiting for a tow truck.I also watch an EGT gauge which is separate from the Scan Gauge.Of the 5 items the EGT in my mind is the most important and the one I use to decide when I need to back off the throttle. The Trans Temp and Engine Temp will normally stay in line if the EGT's are kept inline.

Which Scangauge II gauges are you monitoring? | Good Sam Community

Bought mine primarily for trans fluid temp. I run our 2012 E-350 V-10 24' Class C with trans temp, coolant temp, average mpg and real time mpg. The trans fluid temp will tell you when it is time to engage Tow/Haul for max efficiency. Love the Scan Gauge, would not run without it!

Scan GaugeD:

Boost pressure
Instant MPG
Coolant temperature
% Throttle

Dash gauges already cover voltage, etc.

Thank you so much RCMAN46, that Xgauge code worked! Really appreciate the info.

Oil Pressure is now one of my regularly monitored gauges.

Otherwise, I track Transmission Fluid Temp, Engine Coolant Temp and then I vary between Load, Intake Air Temp and Voltage.

Here are two xgauge codes you can try.

Oil Pressure (PSI)
TXD: 6C10F1221470(01)
RXF: 046205140670
RXD: 3008
NAM: 001D00320000
NAM: OIL

2006 and up
Engine Oil Pressure
TXD: 6C10F122115C01
RXF: 04620511065C
RXD: 3008
MTH: 007300FF0000

Transmission fluid temp (before the cooler), water temperature, instant mpg, rpms (because there was nothing else I cared about).

Depends on the vehicle. The x-code needed does not exist for all vehicles.

Tell us which vehicle you need oil pressure for and someone may have the required x-code.
