Default 2011 STI Open Loop fueling maps Question

Hey guys:
For the 2011 STI MAIN Open Loop Fuel Maps...
Are the Primary Open Look Fueling KCA Additive B LOW & HIGH the same as the old Primary Open Look Fueling Map A & B..?

I know the 2011 STI definitions are still Experimental and just want to make sure I'm not missing anything here.

I posted examples below.
Thanks

I figured this out myself.. Just made some small changes to the Primary Open Loop Fueling KCA Additive B LOW map... Logged AFR with a wideband and saw the AFR change..

Hopefully this will help other CAUTIOUS folks.

ideally you make larger adjustments using the MAF table and you can scale in percentage. the Open Loop table will make smaller changes at a less drastic rate

Stuff like this makes me that my LGT only uses one set of tables.

Is there a parameter that you can log that will show you which set of tables the ECU is using?

Without a clear understanding of how the ECU alternates between the different sets of tables, it seems best to tune them all identically. Unless you are sure it uses one set 99% of the time, in which case you could just focus on that set, and leave the others set up very conservatively - like 0.5 richer, 4 degrees less timing, no WGDC, etc.

^ you could log the final fueling target....or click the help tab and it should tell you

iirc the KCA High table = IAM of 1 and KCA Low = IAM <1 and the failsafe table is for limp mode

That table is probably still not fully figured out. Ususally with alternates they are just an alternate to the A map. So mode the alternate the same way you mod the A map. Best way to check this is to check out the stock tune. If the two are the same, then you know your answer.
