anyone with a scanguage II can help me. I dont have my manual here, it's at my apt in PA. well I filled up today and tried to reset the gallons and price, but somehow screwed it up and now it says Im getting 200mpg. So i put the defualts back on and put everything for the box except tank size, I cant figure out how to do tank size and it still reads 200+mpg.

help please.

damn man i wish i could get 200mpg

 

Make sure you set the fuel type to GAS and set the engine size properly. The fuel tank size setting won't change your MPG, only the miles-to-empty and hours-to-empty readings. It should be set to your tank size, rounded down to the nearest setting.

Oh, and make sure your speed is calibrated properly. Most cars read out about 2-3 MPH faster than actual speed. You'll need a GPS to get a true reading.

 

Also, with the SG2 you can use the x-gauge function to create an average fuel economy reading in "gauge" mode. The MPG reading in gauge mode is "real time" which is useful for certain things, but I have found trip-average MPG to be much more useful. I don't have my SG2 with me, but I'll post the x-gauge codes for creating an average MPG gauge.

 

Lol I figured it out, Im not 100% on how I did it, but I works perfect now.

yeah I have it as gas and I calibrated the SG was off 5mph from my actual speed.

Thanks mcbrew and eltaco
