fuel reserve in tripometer EFI

[Richie M]

I have a 09 fatboy and would like to know how the reserve works on the tripometer. I understand that when you fill it up you have this__ ex. amount of miles until you go into reserve. "or" do you have this__ ex. amount of miles until you run out of gas?? I have seen it go "rL0" flashing how much gas do I have in the tank when this happens 1/4 or 1/2 gal? or even less!

most fuel gauges are a semi close guestimate. Best advice I could give is fill up. reset trip odo to 0 and ride til you think you need gas. Fill back up and check your milage. Figure out how much fuel is left (how many gal the tank holds) And do the math about how much further you could go. The fuel calculator in the ecm changes by riding style updating at regular intervals but would I trust it to keep me from walking? Never. The day you trust it is the one day you will run out. 180 miles on the duece and I have 1/2 gal to .9 gal left give or take depending on touring or stop and go. I realize you should be able to trust the gauge but don't. Just my opinion. Congrats on the new bike.

ALWAYS trust the odometer. Mine comes on at .9 gallons left. I can go roughly 40 more miles until I run out. But I always watch the odometer, because it doesn't change.......

I have an '08 SG, and the reserve is an estimate of miles remaining on the gas in the tank, when it goes to low you have about 10 miles remaining till empty.
