I have added a ScanGauge II to my Class C Born Free. I presently monitor, water temp, transmission fluid temp, RPM and fuel volume flow. I would be interested in what other people monitor with their ScanGauge.Thanks

You can probably improve your gas mileage by 8 to 10% by monitoring average and real time current mpg. The game becomes trying to keep your real time mileage higher than your average. On the very first trip my right foot got quite and education and we improved 9% on a roundtrip we had made several times before.I also run transmission fluid temp and coolant temp, nice to see the digital display, no guesswork. We are currently negotiating on a new C purchase and you better believe I will be taking the Scan Gauge out of my truck and putting it in the new rig. :C

Oil temperatureCoolant tempTranny tempAnd I switch between battery voltage and FICM voltage (specific to the Ford 6.0 diesel engine).

I use Water Temp, Average fuel economy, LOD (Load), and Boost.Trans temp is not available on the Sprinter (bummer) or I'd be watching it.I use LOD to determine downshift points when climbing to go easy on the equipment. I will downshift manually at or before 90% LOD in a climb (if I haven't already in anticipation).

Also use it to tell how much pressure to put on throttle pedal to keep exhaust brake from kicking in on a downhill run.

I finally found the codes for my RAV4's transmission temp. In addition, I monitor water temp, real time MPG, and battery voltage.

On my F150, I monitor; horsepower, intake air temp, average MPG and inst MPG. Definitely has helped my fuel economy in finding how much that extra 5 MPH cost me in MPG. I monitor intake air temp to see how bad my aluminum tubed K & N cold air intake works in stop and go traffic even wrapped in header insulating wrap. Truck is really a dog off the line when intake temps exceed 140. Horsepower is entertaning to see how much is used at idle, uphills, passing and cruising though I'm not sure how accurate that reading is.

Also for those with windshield rear view mirrors, BlendMount has a nice mounting kit.

Monitoring Gallons Per Hour on a 31 ft RV on a F450 chassis is entertaining.

No need to buy a second ScanGuage-II cable.

My main ScanGuage-II cable is nicely coiled up and 100% stored right there by the OBD2 connector.

Mine is seriously routed/concealed and doesn't come out easily. I'm OK with sacrificing the double back tape holding the gauge in place but I'm not OK with disassembling the truck to get the cable out. That is the situation I was referring to.
Ah, I understand better now. I didn't realize your SG2 was already installed.

My main ScanGuage-II cable is nicely coiled up and 100% stored right there by the OBD2 connector. I simply unplug the RJ45 connector there and take out the entire cable. The cable between the OBD-II and my center mirror area is a simple computer internet cable. My ScanGuage-II is completely removed in seconds....cable and all.

I wish someone offered a 90 degree OBD2 adapter to RJ45 female connector without a cable or at least a short pigtail. That would be ideal for versatility. No coil of wire to store there.

Thanks,Mike

Scan Gauge has a listing of what vehicles can give a transmission temp. readout. http://www.scangauge.com/support/x-gauge-commands/

It takes 2 seconds.

The unit comes with a cable with the proper connector to plug into the OBD2 connector in your vehicle. OBD2 is On-Board-Diagnostics, Second Generation. Every vehicle made starting in 1996 has one. They are located under the dash board driver side.

The hard part is deciding where to mount the display. The cable is 6' long but you can easily extend it with a computer cable and connector.

I mounted the ScanGuage-II on my rear view monitor.

The cable was too short so I fished around a longer computer cable and connected it to the ScanGuage cable right by the OBD2 with one of these.

With the original ScanGuage-II cable nicely coiled up below, I can easily unplug it from the fished-thru computer cable, unplug the velcro'd display by the mirror, in a second the entire ScanGuage-II is out and can be used in another vehicle.
