Yeah. You log the Raw ECU value.

Your IAM will most likely drop at some point though regardless. Alot of times there will be a singularity in the timing map that causes knock and the IAM's will drop and correct themselves within the same pull.

The IAM is only one of many things you need to focus on though. I consider the IAM the Dummy Light of logging. I generally check my IAM's for the entire run first, because it is the first clue of something going wrong. A/F, timing, knock, etc. any of these could be problematic or out of range of what you want, but IAM may not reflect this.
