Power commander v distance to empty.
Hey guys just curious with a piggyback unit like the power commander v if the fuel distance to empty is still accurate or not. I have not tested it out yet and this bike is new to me but when I filled up the other day it said 411km to e. That seems pretty good! I just want to know if I can trust it with having my power commander installed and adding fuel.

Only one way to find out. Put a small gas can in one of the bags with a little fuel in it next time when you're relatively low on fuel and then ride around until you run it out. Different bikes can have different results. YMMV

It is a constantly changing number.
It will usually be pretty close, but it will never be 100% accurate.
Example would be if it listed 250 miles to empty, and you rode 10 miles.
If those 10 were under ideal conditions (level interstate for instance, with average speed), then the distance to empty could very well still read 245 or so.
But if those 10 miles were in hilly terrain under heavy load, the distance to empty might read 230.
So, as the number is calculated the new distance to empty is accurate at that instance.

Keep in mind that "distance to empty" is a calculated number (based on current fuel usage, speed, engine load, etc).

Yes I reliaze it constantly changes, just want to make sure it still calculates somewhat close. Just didn't want to find out the hard way that it's way out because of the power commander.

have the PV2 and when I view the Trip A (which I reset at each fuel stop) it is 100% accurate with respect to the amount of fuel I used - I would think their PC would be the same but there is only one way to find out.

Thats the mileage I get on my 11 RG Ultra... so I'd say it's pretty damn accurate. I don't have a PC V........yet....!

Don't know what the PVC would have to do with it. The "till empty" is calculated on distance you have traveled and how much gas is flowed for that distance. The calculation is constantly updated based on this. Flow more gas for less distance and the "till empty" mileage get less. Flow less gas for the same distance and you will have more miles "till empty". The computer knows how much gas is left in the tank and includes that in the calculation.
The PCV might give you more or less mileage, but the "till empty" will still be calculated the same. I know that my "till empty" is pretty accurate with the PCV, just like it was without it. This calculation is not 100% on the bike anymore than the same function is on your car.
I did find on the one time I ran out of gas that you usually get a few more miles than what the computer says you are going to get.
