Interesting......yep,understand what you mean about the map order.
If theres one thing ive learnt about these cars,its that the fuel guage under reads the amount of fuel.....according to my book the guages arnt 'linier' and states that empty is around quater full,quarter is half and so on.
I can well believe this because in my old WRX that had the old 50L tank,it stayed on full on the guage for ages,then dropped.
Also even when it was on less than empty i could never fit more than 40 L in the tank.
But as you say,if you do the map order correctly,it should be no probs.
Does it run a little rich if there is more than meth dregs left of V power map?
Have you got some spec on your car on here (ie projects thread)
Mines a built lump too and would be interested in what you've done.
Cheers dude.....
