So I installed my pcv and autotune and flashe sbu ecu. I have completely removed and capped off the stock o2 connector and removed the 02 sensor. So it suprised me today to see my mpg counter working. I was like wtf?? The only o2 sensor on this bike is through the autotune so the pcv must be sending the ecu mpg data... from what what I can tell it's accurate too lol. Fing werid man.

No. The ECU calculates mpg on its own...it knows how much fuel it is injecting and how far you have gone...mpg...has nothing to do with having an O2 sensor...
