    Trophy trip computer.

    The Trophy computer calculates fuel used and average fuel mileage per trip. When I compare fuel used as per the computer to fuel I add at the pump, the pump adds more fuel per fill up than the computer says the bike used since the last fill. So, the computer says I get better mileage as compared to when I calculate miles per gallon using the fuel receipt.  What is more likely: the computer calculates better mileage than the  bike achieves, or,  I am being robbed at the gas pump. Ideas?

    Here in the USA, the government requires periodic certification of fuel delivery equipment, and I believe most are quite accurate.   Vehicle computer calculations for mileage are notoriously optimistic; my TTSE included.  Usually ~ 1-3 miles per gallon optimistic.

    In a previous discussion about this I wondered whether the Trophy Trip Computer
    was using any of the speedometer data - which always reads faster than actual speed,
    to make such calculations, and if so whether this could explain the similarly optimistic
    MPG figures that the Trophy Trip Computer produces ?

    Gas pumps are also inspected and certified in Canada also. I suspect the Trophy computer is not accurate. Thanks.

    You can quit wondering coconut.  It's true.  Mine is always off by about 1.5 to 2 mpg.  That makes me think the odometer is accurate and the speed isn't.  Makes since if the odometer is run off the driveline and not the computer.  I think next time out I'll check the mileage and trip time and see if the avg speed is off by approximately the same as the speedo.  My aren't we getting deep into this.  :018:

    On mine, it depends on how I ride.....

    All highway very accurate, riding in the mountains trip computer shows I used 1/2 gallon less than actual fill up.

    One tank was all 4 lane 65-70 mph for 200 miles, I was surprised the computer showed 48 mpg and it was dead on, I confirmed it with good ole math.

    I did an IBA SS1K last year in Sept and it was mostly 2-lane 55mph roads (55mph -- yeah right  :018:). TTSE's computer showed consistently pushing 50mpg -- 49.5 I think was my screen average at the end -- using gallons at the pump and miles traveled on the odometer (which is also within just a few of the ride coordinator's), I got 49 mph. For me, that's close enough to calling it accurate. For highway riding.

    Gas pumps have within a range to get a passing grade , one of my jobs many years ago was to calibrate the pumps.
    I was told to be on the low side in five gals you could be eight cubic inches low or high we set 4 low.
    That's one thing now how much gas do you get in the tank do you put it on the center stand or leave it on the side stand , will the pump let you top off the tank , most pumps will splash gas all over the tank if you try to top off the tank , don't ask how I know.
    My car is the same way it show better than it really gets , the better the mileage the larger percent you will be off to be on is to have had everything go right and that is never me.
    The good thing is once you know the percent it's off you know just how far you can go.
