So helping a friend and we came across this 2 bar VVE table.

Is it just me or is this just plain wrong. I'm taking it the only way this could work is if PE modifiers are fixing the fueling over about 80kpa???

Hey Antony,

The 1-bar VVE table is correct... the 2-bar and 3-bar (whichever one will be used) need to be fixed up and corrected

( and you will have to redefine the VVE zone boundaries ).

Yes it is horrible, but Holden never needed to account for 2bar so it does taper off pretty bad beyond 100kPa.

The car is meant to be tuned for 9 psi.....

The map sensor was incorrectly scaled to around 1.1 bar and kind of runs although a bit rich and lean at times.

So in theory if I was to take the 1 bar and stretch it in to the 2bar. (I know what kpa is really against the incorrect scale.) it would be fine once the map sensor reads right.

I take it there will be some adder tables a bit messed up. What else? I'm doubting all the tables are scaled down. Timing maybe.

Thanks all.
