It will be a logging issue with OFT.
if KC Learned logs ok you can derive IAM from that.
look at your log here
http://www.datazap.me/u/lemonzz/log-...zoom=1274-1474
look at the log at rpm =6800, load = 1.1, KC Learned = 2.34 or around that area.
then look at the Knock Correction Advance Max A table in your tune as below
look up the same rpm/load value you get 2.81
if IAM =1 and no FLKC knock then the value in the Knock correction table should match the KC Learned value
yours is less so IAM is not 1 or you have FLKC (fine learning knock control ) active which you have not logged
If we assume FLKC =0 then
IAM = (KC learned value - FLKC) / (Knock correction Max A Value) at the load rpm point
IAM = (2.34 -0) / 2.81
IAM = about 0.8
the ECU interpolates values between cells so this is only a rough guide and we dont know what FLKC is (which may not logg correctly either.)

Talk to the openflash guys about the logging they should be able to fix it up for you. email or call them.
