So is there any correlation between boost pressure ratio and engine load?
Max load for the tables in the software is about 2.0 but enters in as 1.989 or something like that.
I'm experimenting with this setup right now. I got the car running yesterday and I entered my first tune. It seemed to flash ok but it is throwing rich codes for both banks almost immediately.
I'm addressing that issue but I don't have any practical basis for the load values.



Looks like I'm a little late to answer this question.

I would however say that it's more related to density ratio then it is pressure ratio.

From what I surmise the ECU knows how much air the engine should consume via the setting saying what the engine size is. So more than 100% as stated above is a higher load.

Load values in my WRX (yeah.. I know different ECU) hit 2.4 (which with more assumptions is about 240% load.. which running 22 psi of boost could happen).

Anyway.. to sum things up.. yeah.. more boost equals higher load values which means you need to rescale your tables otherwise you'll get no real control over the higher load sites.
