Features are meaningless if you dont use them or if you dont know how to use them. ScanguageII could be used for multiple purposes. If you do not understand how your car works, i suggest you learn first.

What i use it for is for fuel consumption. Like many people who uses it, they monitor their mpg. With the other readings such as Throttle position and Engine load, you can refine and optimize your driving technique by observing how your driving habits affect the multiple variables that ultimately affect mpg. You can also use it to evaluate how the driving environment affects your vehicles performance. For those who use it for mpg. i suggest you follow the directions on calibrating your gas tank: Use the same gas station. After calibration, the scanguage told me my mpg was 33.4, manual calculation was 33.1. so it was pretty accurate. Its never gonna be perfect as there are so many variables that affects mpg calculation, including your tank shape and piping.

I wish the cable was a bit thinner so its easier to route, since most port for the OBDII are under the steering columns, the easier the routing the lower chance the lower the chance the cable will affect the pedals. The build quality could be improved too, the buttons and the housing feels like a hobby or two bit operation, not something that was manufactured with care. I also wish the auto start would turn the device on when the car starts, no 2-3 seconds after the car starts.

It does what it says, very easy to hook up, adjust, and see. even my wife likes it, and does not like any of my toys. It would make a great Xmas present.

I had been wanting a trip computer/info center for quite some time. This product is great. Even though the directions seem to be confusing, it is very easy to setup and use.If you plan to use to trouble shoot a vehicle other than the one you install it in, it would be advisable to purchase an extra cable.

When I first installed it, the side port didn't work, so I pluged it to
the back. I left it in the car, it was hot that day (85F), the display locked up. Then it worked fine for a week. Today it locked up again, so I unplugged it and plug it back again, I got a blank screen, I tried the side port and it worked again. I called the company (manufacture)several times with no answer, I also emailed the tech support, no answer. I am returning it to Amazon.

The ScanGauge was everything I wanted and more. Once I set it up and calibrated it, it worked great. Like everything else in life if you spend a little time setting it up iniatally it will work great which only takes a few minutes with the manual in hand.
