Totally bonkers 'Miles to empty' on 2020+ Spyder - can it be fixed?

If you fill up a tank and ride at exactly the same speed for the entire ride it will be pretty close. The issue is that it is adjusting based on your current speed which is usually varying during a ride. Like was said, watch your odometer and use that as determining when to stop for fuel, or in my case, when Momma wants to stretch.

I'm averaging 30+ miles per gallon. So on a refill with a full tank (7 gallons) and 30+ mpg the estimated Miles to Empty should read 210+ miles, however mine only shows 170 miles? Any suggestions/ Oh, my bike is a new 2026 RT S2S and I've currently ridden 350 miles

It does this on my bike too. I assume it is computing the fuel range using the average fuel consumption I was getting in the past so many miles or so much a time period. My Range Rover does this too.

As I ride for a while, the predicted miles until empty seems to correct itself and make more sense. I'd love to know the algorithm.

The "miles to empty" feature is wildly inaccurate.
Best to keep track of miles on the trip meter and calculate in your head. The miles to empty has always been very pessimistic for me. I've been down to 30 miles on mine and barely put 5 gallons in. I get about 39 mpg, which tells me I really had close to 79 miles left in the tank.
I would not run it that low, but here in the western US it's important to know what's really in the tank. We often ride roads that have long distances between services.

I completely filled mine yesterday and it tells me It has 164 miles to go. I know this is pretty low.

The wife and I rode maybe 75 miles this morning and getting back to our home town the Spyder was down to one red bar on the fuel gauge and It was intermently flashing a low fuel message in the top right corner of the display screen. I pulled into the Shell station and was only able to put 5.2 gallons in the tank so with that said I could have easily got another 50 miles before running out. I think the gauge is calibrated to get the rider to fuel up way before the chance of running out occurs. I've been running 93 octane since new and don't like running the tank near empty so I kinda like the way the gauge is calibrated. 5.2 gallons is the most I have ever toped it off to.

Many of you seem to forget that you REALLY don't ever want to run out of gas in your Spyder, as doing that WILL damage things; and even if you are lucky enough to avoid your engine needing expensive repairs (or maybe scrapping) now, the damage caused by running out of gas, or maybe even just running low on gas, is irreversible, cumulative, and in the majority of instances, ultimately terminal!

You always NEED to have at least a couple of litres of gas remaining in your tank, as the fuel system uses that remaining fuel as both coolant and lubricant, and all the damaging contaminants end up in the bottom of the tank, meaning that if you get down too low in the gas remaining, bad things will start to happen to your engine, or maybe even happen now! So if you think you could've still run for about 50 miles on what gas was remaining in the tank, that's about right if you don't want to damage things! Anything much less than that is getting pretty risky!

There's a lot more discussion on this that's already been posted here on the Forum, so I won't re-iterate it, Search is your friend; but seriously, don't be the sucker who continually runs their tank down to empty or even almost empty, you should definitely be starting looking to fill up by the time it hits about 1/4 of a tank remaining, and if you're looking at buying a used Spyder, don't be the poor sap that buys a Spyder that's been run down too low in the gas remaining too often! I'd suggest steering well clear of one that the seller admits has ever been run dry!

Just Sayin' - Again!!

Just set one of the trip miles to zero when you fill up and when it gets to around 250, fill up again. Do that every time you get gas, or if you stop for gas early, set it to Zero then. That is the way we kept up with it before bikes had gas gauges. It you ride more in the city or pull a trailer some, it will make the miles really stupid on the Can Am miles to empty numbers. Anything that changes the normal routine will confuse the computer, which was not that bright before it got confused. Mine will take about 4.5 to 5 gallons somewhere around 235 miles. It depends if I've been pulling the trailer much or riding the crooked roads where you drop down to 3rd and power back out of the curves.

That's 47+ mpg. How on earth are you getting that mileage???
