MPGuino metric version bugs?
Hi!
After using MPGunio for a while I found a problem. VSS is calibrated and works well, but consumed litres and average consumption does not match. If I calibrate it using consumed litres, average consumption is off, if calibrated by average consumption, litres consumed are off...
also there is a difference between instant consumption, current and tank average. I hooked my mpguino up to a signal generator at home to have constant speed and injector input and after reseting tank and current and after `driving` for a while I collected the readings and this is what I got:
cruising at 100 kilometers per hour:
instant consumption - 12.66 l/100km
tank average and current - 10.27 l/100km
after 10 kilometers consumed fuel showed 1.27l, so that means instant cons. is correct.
why are current and tank averages incorrect?
Is that a calculation mistake in the code from converting mpg to l/100km?
Thanks
