I know this is designated as a subforum for the Cobb ST, but I think the ecu gurus in here may be able to explain this for me.

I have an 05 STI, currently running a STG2 OTS cobb ap map. Recently purchased a tactrix cable and have been educating myself and reading anything I can get my hands on. After pulling some 4th WOT logs, engine load was peaking around 3.2 ish around 3K RPMS, and holding above 3 until it tapers around 6K RPMS.

From looking at the stock ECU image tables , and others, it appears the fuel and timing tables only have parameters up until 2.75 load (g/rev). My question is what does the ecu look to running WOT with loads greater than 2.75 to provide fuel/timing? Or does the 2.75 load column just go to infinity?

I attached a log for reference.
