Fuel Management XT22 Wrong?

Why does my fuel management software only list 35.5 gallons when I reset it to full?

I’ve had quite a few issues with the fuel management. It would say 80% full sitting still but the second I take off it would drop to 50 or less. It would also show 50% with 13gal. That doesn’t add up to a 65gal tank. Dealer said we should reset system and make sure software is up to date. Then fill up the tank, hit full, and go from there. Guess we’ll see if that works.

I could be wrong...but I think it has to do with MC not wanting us to run the fuel tank below 1/4 full (to ensure the fuel pump stays submerged).

When I fill my tank I push the fill button on the big screen, fuel resets to 100% for about 40 seconds, then goes back to zero. I tried resetting after the tank was down below half and that didn't help. My dealer just sent me a new sending unit, going to install tonight, will let you guys know what happens!!

It sure is frustrating when a manufacturer spotlights technology that doesn’t work! Based on my fill up today I showed 47% and the biat took 18 gallons to fill to full. Those numbers work out to the system thinking the tank is only the 35.5 gallons it shows as full. This kind of stuff drives me crazy!

First thing I did was turn that off. Not sure why it’s even necessary, or a big deal.

Weird you guys are having issues. I love it, one of the best features on the boat.

What your screen shows when full will not equal your actual tank size, as said above its so the boats never ran with too little fuel to keep the pump cool.

When my tank is completely full the sending unit shows 3/4 full, and fuel management shows half. I've just been trying to fill up every few hours!!

Are there still screws on the top of the new senders to adjust the gauge? If so, I need to do that.

Mine is an 2018 NXT22 and I had a similar issue. I topped off 2 times before I got below a half tank and it would not read full (it was full). Dealer said to run it close to E and refill so the meter in the tank could reset. That worked.
