Hi there guys,

I have already managed to calibrate the speed in accordance to my vehicle however the mileage is wrong in MPGuino.

I build my own PCB mpguino, however I used a 20Mhz crystal instead of 16mhz.

Is this the reason why my mileage is wrong in mpguino?

My ATMega328 was bootloaded on Duemilanove, and I saw the crystal on it was 16Mhz.
