MPG oddity on 2021 RTL

[ollicat]

The strangest thing happened to me this last week. I filled up my gas tank and reset both Trip 1 and Trip 2 back to zero. As I rode for the next 100 miles, Trip 2 was accurately reporting miles driven and approximate MPG. Trip 1 on the other hand was completely crazy. It started out saying I was getting 3 - 4 MPG. Then after over 100 miles, it made its way up to 7.4 MPG. Obviously that was way incorrect. Trip 2 was reading 31 MPG which is about right. I have 3500 miles on my Spyder and this is the first time I have seen the trip counter do this. Has anyone else experienced this oddity? I will reset it on my next fill up and see if it does it again.

I have a 2020 RT LTD and it will from time to time take its sweet time resetting back to zero, or better put reading from zero after a fill up. Put your exact symptoms no.

I had this happen one time on my 2020 RTL. Only difference I can remember in my routine is that I reset both meters BEFORE turning off the ignition after pulling into the gas pump. Normally I fill up, then turn on the ignition and reset. Never had the issue again (knock on wood).

That is EXACTLY what I did. I was waiting in line to gas up and thought I might as well reset the trip meters. Let me try next time doing it AFTER I refill.

I have noticed this too on my 2021 RTL. It seems that the trip screen that is active gets the calculations and the others do not. I noticed that if I ride with Trip A active it will calculate the numbers but if I leave the Total screen active Trip A has goofy values. I track my mileage using the Fuelly app so I pretty much ignore MPG that is calculated.

Why not just reset it now. See if it fixes itself.

Because my OCD won't let me reset a trip odometer half way through a tank. LOL

I found that if I fill up then start the engine and wait until the phone connects and the radio starts I can reset the trip meter and the mpg reading seems to work properly

No problems with my 2021 RTLtd. I just stop, fill up with gas, pull to the side of the station to get out of other people's way, then reset Trip A and Trip B to zero.
I have double-checked my mpg with the hand calculator against what the Spyder is telling me the mpg was ... sometimes might be 1 mile difference but usually the same.
