'13 Freightliner M2 106

Put this in my '13 Freightliner M2 106 and it is wonderful! It takes a few passes over the manual to get used to all the settings, but setup and installation were a breeze!

Great Tool!!

I use this in a 2006 Freightliner Columbia with a 14.0L Detroit Diesel. It's a great tool for for saving fuel.

GREAT customizable engine monitoring gauge

Very easy to customize and monitor various engine elements. Installed on a 2015 JayCo Seneca 37TS (6.7L Cummins ISB-340 engine).

Better results then I expected!!

I was debating whether to buy a different more expensive engine monitor but talking to a number of RV diesel owners was convinced that this would give me the best bang for the buck. Main reason i purchased was to monitor engine and transmission fluid tempature. Suspected that the gauges on my coach were giving me false readings. Hooked up the ScanGauge and within an hour knew that my gauges were off by as much as 20 degrees F. In addition, this gauge gives you instant and average mpg. It helped me to be a better fuel conscious driver. Prior to the installing the gauge, I would run with traffic and averaged 6.0mpg, with the gauge monitoring the instant and average MPG I was able to determine the best fuel enconomy speed was 62 mph. Maintaining that speed my average fuel consumption went up to 7.6MPG. If this continues, and I haven't any reason at this time to think otherwise this gauge will soon pay for itself.

Does what it says

I have a CAT C9 and this gauge tells me almost everything I need to know, especially boost. Only issue, though not specifically a flaw in this unit, is that the plugs do not hold themselves together and I had to use a tie strap to keep the unit plugged into the diagnostic port on my RV.

Customer service is OUTSTANDING!

I bought this for my 1998 Holiday Rambler motorhome with Cummins ISB engine and had an issue where the unit would always power off after about 12 seconds. A replacement unit was sent that did the same thing. Then we found the problem was the unit cannot read RPM from my engines computer for some unknown reason and that was causing the unit to shut off. ScanGauge then sent me a CUSTOM programmed unit that ignores the RPM signal and it works GREAT! WOW what service, highly recommend!
