Trip Computer accuracy

i was just trying to get some ideas from GP owners with a trip computer. on fuel used or anything dealing with fuel...how far off is from what it really is?

 

here's mine: 14.1 fuel used....fill up was 14.9

I get about the same thing you do. I don't rely on it with my life, but its close enough for my use. My econ. and stuff is always great.. but my fuel used and trip are always slightly off. Trip isn't bad... with the odo reading about 400 miles... the trip computer will read something like 405.6.. something in that area.

i think that .8 difference could be from fuel in the pipe that goes to the tank.

 

if the the fuel consumption goes off of the gas gauge it wont start lowering until the fuel is burned form the gas intake pipe.

 

if not..

leaky injectors? or causes from any alteration from stock. meaning performance parts
