“Just plug it in and data starts coming out. Not flashy, but extremely useful. Can be used to replace expensive gauges as well as perform diagnostic work. Your frends will want to borrow it to check out their own vehicles. Variable color backlighting is very cool. One word of caution. Do not reset the error codes and then bring the car in for service if you think you have a real fault. The dealer will not be able to diagnose your car if you have reset everything. Also, telling the repair place what the error code was will not help. For example, MINI and BMW have an entirely separate set of error codes (not the government mandated P codes) that are only read using their proprietary diagnostic equipment. I use the ScanGauge as a supplemental gauge set since many modern cars with gauges do not display information in a straightforward way. The water temp may be “filtered” so that the gauge reads normal unless there is a wild excursion. Real temp variations are suppressed to avoid service calls.”

“I saw a review on Mojo channel where the reviewer used the MPG display to increase mileage. Based on this I bought one and I’m not disappointed. I can see this easily paying for itself in less than a year. The real time MPG display allows you to tame that lead foot and get awesome mileage on a long run. I did an 8 hour drive last week and must have got conservatively 5MPG better fuel economy. You do have to work at viewing the display and feeding it back to that right foot. Very easy to install – under 5 minutes. If you’re not a gadget fan then don’t buy it.”

“At first I justified buying this because in the long run, i could change my driving habits for better fuel economy, saving me money. The instantaneous fuel economy and throttle % indicators have helped me accomplish this. I am now getting better than the EPA rated fuel economy on my car. EPA city: 20 Highway: 27 Combined: 23. I am using this to get an average of 33 mpg. This is great now that gas prices have soared, and that is with no other modifications to my car than plugging this into it, and adjusting my driving style. Considering the amount of driving I do (90 miles/day typical), the Scangauge is priceless.
Not only does it give fuel economy, It also has a variety of other sensors. Anything the car’s computer knows, it can tell you. Coolant temperature, RPM (great since my car doesn’t have a tachometer), MPH, gallons of gas/hour, and many more. It also stores trip data, such as top speed (great to know if you have a kid driving), avg speed, top RPM, total distance, gallons of gas used, and avg fuel economy, not only for the current trip, but for that day and the previous day, and also for the tank of gas. It also lets you know if it has been disconnected from the car’s computer at any point during the day.
In addition to these functions, it also provides error codes that can easily be referenced online, allowing you to diagnose and fix your own problems instead of taking it to a mechanic who will probably charge a fee just to plug it in. I printed them out so i can easily decipher whats wrong in case something happens while I’m on the road
I’ve had this for 3 weeks, and I think its a great product which is consistent and indispensable once you have one.”
