I've been doing some tuning lately to adjust for the baffle I put into the Jardine slip on that I have and I'm a bit confused. It's running good and the AFV seems to stay put quite well on any given data logging session. I've checked the AFV after a bunch of rides and it seems stable except for temperature variances. Last week when it got into the mid 90's the AFV was staying at about 105. I tuned it when it was in the mid 70's and it will stay at 100 in those temps. Last couple of days I've checked it running in the 60's and it's dropped to 95.

In my mind I would have expected lower AFV values as the temp goes up. I fear the ECM is more complicated than my mind though and it is probably working correctly. (The ECM that is.)

Anyone know how theirs reacts to temp changes?

Thanks Tom. I know that there's many variables that I don't have the data on, but big temperature swings. I just wanted some reassurance that there wasn't something else causing it to react in a bad way. Sometimes the ECM is hard to get your mind around.
