Mpguino says 309.72 tank miles and 7.7 gallons. 309.72 / 7.7 = 40.22. Mpguino tank MPG calculation says 50.25.

Is there something else that needs factored in?
Hi! If I remember, I noticed the same problem some 3 years ago. If I calibrate mpguino by average readings, averages are precise since then, but tank litres (yes, I used metric version) are way off, and if mpguino is calibrated by consumed litres, litres will be displayed correctly, but averages wont...

I solved the problem my multiplying instant, current and tank readings by a constant (I think it was 1.2 or 1.25) and calibrated mpguino with consumed litres and averages were correct too. I dont remember why, but multiplying only worked in Instant/current, instant/tank, and big screens, but in current and tank displays, average readings were a lot lower than they should be, but litres were correct. since I always used mpguino with instant/current display, it did not matter.
Now I want to update my mpguino with improved code found here. I tried alin151 code, but it has some strange bugs and now I will try t_vago's code as recomended here...

good luck
