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.
