Question, if the fuel used/mileage etc needs a calibration factor entered on the trip page in order to be accurate, how can the VE #s be correct??
If the system can't figure out how much fuel is being used, it can't possibly be able to accurately calibrate VE's can it??
Appears that mine was off approx. 9% based on what it says I'm using vs what I am seeing on fill-ups, are my VE's that I've gotten from Autotune runs wrong also??

I have to assume that the amount of fuel used is based on injector duty cycle, which I assume is also included in the VE calculations, not??
So if one is off they'd all be off by an equal amount.
It appears, based off of GPS readings that my speedo is dead on, or VERY close, depending on how much you believe GPS readings.

OK, I did my first auto tune data log session and, as I compare the original tune to the new one, the VE tables are the only thing that changed at all. No changes whatsoever in the timing. Is this normal? Also, I had assumed that it would modify the original tune but it made me save the modified tune to a different slot, so I assume I need to load THAT tune to the bike, and then do further auto tuning from that map? Sorry for the rookie questions...trying to learn.

OK, thanks. So we still can't make timing changes right on the PV itself? Still rely on a computer for that?
