tire size (Does ScanGauge have adjustment for different sizes)
 

Santa is stopping at my place first this year.....as I sit on my porch wanting for my scangaugeII......:D......

I run 255x45x18 tires. the factory size is 245x45x18. I know that the car odometer and mpg gauge is off by about 3% because on my last long roadtrip i used my garmin nuvi gps to track my true mileage.

Does the SGII allow for adjustment for tire size?:confused:

Yup. There's a "speed" offset which you can use to correct for gearing/tire changes or OEM errors in the speedometer/odometer.

FYI, you can view the ScanGauge user manual online:
