Well Jedo it depends on how old your car is.
The scan gauge reads all that your on board computer knows. If you have a car too old - i.e. no onboard computer you can't use a scan gauge.
On their website they list all the vehicles you can plug into.
IF you have a car with on board computer under the driver's area there has to be a plug for manufacturer and service centres to plug into with their computer. You use this plug. It is meant to be easy to find. Look around under your steering wheel area. The plug picture is on their website.
Once plugged in follow your instructions to set you car engine size, fuel tank, etc. Also get a GPS
and calibrate you actual speed. Most car speedos run about 4 to 8 km more than you are actually doing - good so you won't get a speeding ticket. A bit misleading on calculating fuel economy and distance times etc.
Hope this helps.
