Fuel Indicator not going up - OFT
 

Anybody experiencing their fuel indicator not going up after filling up? After flashing with the OFT tune, I was at about 3/4 full and went to top it off. Needle didnt move at all. Drove about 75KM and topped it off again and still not moving. I know there's gas going into the tank.

The fuel level indicator has nothing to do with the ECU flash/OFT. If the problem persists, I'd take it to the dealership. Perhaps the fuel level sensor (in the tank) is damaged or faulty. It would be the first time I ever heard of that problem in this car though.

Thanks Shiv! Didn't mean to really point fingers at the OFT (Awesome device BTW). I didn't have a chance to fill a full tank after I got the tune so I assumed there might be some relation to it.

Do you recommend me flashing back to stock before bringing it to the dealer?

Very unlikly they would pick up tune but it only takes a few minutes to flash back to stock ,
.Also if they happen to update your rom at the dealership you can erase your oft and marry up to new rom calibration.

Common FRS/86/BRZ issue, fill up at quarter tank and you'll never run into this

I have had this before when putting in just a little bit of gas for autox.

This happened to me as well before... if you disconnect the battery and wait a while (or reset the ecu with a reflash) it might go back up.
