F800GS computed range on full tank wrong?

The system cannot tell exactly
how much fuel is on board when
the tank is completely full.

A $15,000 bike cant tell if the tank is full? That's like the Space Shuttle not knowing the fuel level. Simply Unacceptable!

It does exactly what it needs to.
Your driving past a gas station, you know the next station is 40 miles away and it says >50. Do you push on, or buy gas now?

I am from the "be prepared" crowd so I buy gas now.

Migs,
Don't disagree.
But I hardly think you can equate a BMWF800GS to the Space Shuttle.
Maybe an average car...but not the shuttle.

I bet the F800 has more computer power on board then the Shuttle. Keep in mind the shuttle is real old, and they only use old proven technology (for proven reliability) at NASA.

"It’s true: The brain of NASA’s primary vehicle has the computational power of an IBM 5150, that ’80s icon that goes for $20 at yard sales. According to NASA and IBM, the shuttle’s General Purpose Computer (GPC)—which controls, among other things, the entire launch sequence—is an upgrade of the 500-kilobyte computer the shuttle flew with until 1991."

Like any gauge, it's just a ball park. But wait, I want to know down to the exact foot how far I can go on a tank durn it.

When the light comes on I know I should think about getting gas. When the gauge says < 37 miles I know that I should think about where I can get gas. It does the job it's supposed to do.

I usually fill up every 185 to 200 miles. Never let it go all the way to zero. Never had any need to.

ditto.

I had a Ford F150 in the 80's with dual tanks. I used to run 1 tank until the truck died, then switch tanks. Then Ford Warranty started having to throw replacement fuel pumps at it because the bearings were going bad.
I think I replaced both pumps 2X in 30,000 miles. Later it dawned on me, "a fuel pump is designed to pump fuel. As long as it has a fuel pressure load on it the RPM is limited by the load. But run out of fuel (or even get low where the pump pickup comes out of the fuel for an instant) and your pumping Air. With no load, the RPM will climb as high as the electric motor can run."

SELL IT and buy a Burgman scooter. You can tell how much gas is in that anytime you want buy picking it up and sloshing it around....with the lid open.

I have to go analog with my MV...open the cap and look.
