...well for my car at least...km before refill on the center console read 740km left! This after driving highway from 'sauga to scarborough. Just got the fuel sending unit replaced and put my spare stock ecu back in.

just thought i would share. I never thought it could read that high =) It has never read anything over 590km since the day I got the car =)

..with the car in gear but without on the accelerator. I've seen 800+... but only lasts for a second :-)

i got 680 km after filling a full tank yesterday too, and i thought that was weird also....the highest readout since i got the car

and yes, i usually get around 580-600 with a full tank
