I'm currently playing with the 0.86 version of the code on my arduino-based MPGuino. There's a section commented out:

//#define dispadj 1000
//#define dispadj2 1250

//#define injhold parms[injectorSettleTimeIdx]

Which I used. I've noticed something very strange though - my instant mileage appears to be calculated correctly but my trip mileage seems to be 1.25x my instant mileage - for instance cruising along at 36mpg will give me an average trip mileage of 45. What variables do I need to change to correct this?
I haven't checked tank mileage against instant yet. What other factors might be affected?
