I thought most fluctuation was due to lag from the O2 sensor measurement to the ECU adjusting fuel/timing, but I'm not a tuner, and Subarus are rather new to me.

Well it's been a slice, but I have my post count up enough so I can formally introduce myself elsewhere. Then I'll need a few more so I can see web addresses and the like...

Have fun with this. (Was this just over someone calling you an ass in the AirCare thread?)
