I recently bought a scan gauge, trying to keep better track of my mileage, plus some of the other features are kind of cool. My only concern is the mileage indication while in MDS mode. The scangauge is onlfy indicating around 10-12 mpg while in mds. I figure it must be halving the milage or something, maybe it isnt taking into account the fewer cylinders firing. Just wondering if anyone out there has any insight into this.
i have a dual setup for my truck but i bought it so i could reset my speedo for the bigger tires on the truck and to monitor other metrics, but if you go on there website they have a forum on there where you could get an anwser
