Fuel computer accuracy
#1
The 14 models have a trip computer which tells ( in two modes A& B ) mileage, gas used, average fuel mileage, and amt of gas left. I am continually amazed by the accuracy of this little computer, I mean being an old guy, I have to wonder how it measures the gas I use? Is it by weight? Or does it actually measure the fuel as it's fed thru the 4 throttle bodies? Or is there some other magical thing only young people would understand? Because it amazes me.

At any rate on last nights ride I was down to two bars and passing a station with a fairly good price on gas so I stopped and topped it off. Same procedure as every time, bike on the side stand, filling from downhill side with my left hand as I peer into the neck of the tank, fill until gas comes up into the neck and shut it off. I turned around and hung up the pump handle and the pump said I used 2.5 gals. Close cap, put key back in ignition, put tank bag back on, collect my receipt, fire it up and reach down to reset B mode which I use for the amount of miles on the tank ( A mode is for amount of miles driven daily as I record this figure in my log ). Anyhow B mode says I had driven 137.5 miles, push the button again and it said I had used 2.5 gallons ( exact same amount of gas I had just put back into the tank), push it again and it says I averaged 55 mpg. Same results I get when I plug the numbers into the calculator in my phone. Push the button again until miles on B mode pops up, and push and hold until it zeros, then push it back until I get to odometer. Ready to ride again.

I mean I can remember when we used to see how much gas we had left by opening the gas cap, rocking the bike back and forth between our thighs and listening for the volume of slosh we heard in the tank. Back when the bike would start sputtering and you'd reach down and turn it to reserve, Then when it quit altogether, you'd lay the bike down on it's left side to get the gas trapped on the right side of the tunnel over to the left petcock side. Then stand it back up and fire it up and ride another couple of miles, hopefully finding a gas station before you ran completely out.

Now your bike accurately keeps track of every drop in the tank. Like I said, these computers are simply amazing.

It's amazing this system Ferret!
In my Shadow 600 the marker it's the power loss, and in this moment change your mode to reserve tank , and search the near fuel station
Sorry for my english translate style

It's not the computer, the import thing is, that the sensors, e.g. to measure current volume of fuel, current speed and covered distance have become much more accurate. The computer then just adds numbers.

regarding the fuel.....
is there a sensor to measure the fuel in the tank that feeds the computer or does it keep track of the fuel usage from the fuel pump?

Here's how they work in cars: "The fuel economy gauge makes a calculation by counting the number and duration of pulses made by the fuel injectors as they squirt gasoline into the combustion chambers of the engine. The onboard computer system divides the distance the car travels by this estimated fuel consumption". and also "Honda uses additional inputs to calculate trip mpg. We look at the fuel-consumed data that comes from the engine-control computer, but we also track the float sensor measuring the fuel level in the tank".

It is pretty amazing.... mine has always matched what the pump says too!

I have the 2014 Standard. My "B" button seems to be inoperable. Can someone tell me for sure? The Owners Manual does not differentiale the standard vs. the DLX that I can tell.

I thought the 2014 std gauges were same as 2014 DLX only with black faces. It should cycle odometer (total miles on bike), A distance traveled, A gas used, A mpg ave, A fuel left in tank... B distance traveled etc each time you press the left button. Hold button down on distance traveled to zero either A mode or B mode.

Look in your owners manual and it should show that. In the meantime another 14 std owner should chime in

It does all that, and mine also shows instant fuel economy.

I haven't figured out what that instant fuel economy number is, but it always seems high, like in the high 60's
