Did some tuning on the 928. Seems there are 6 maps that need to be tweaked. The cat map, non-cat map, immediate o2 adjustment, the adaptive o2 adjustment, the ignition advance map, and the idle ignition advance map. I can tweak the cat map and non-cat map, but all I can do is reset the o2 adjustment maps. So...have to reset o2 adjustment maps, then tune a little, then reset the o2 adjustment maps.

Finally got the idle nice and smooth. Another 928 tuning guy happened to be in town today and dropped by. He didn't know about resetting the o2 adjustment and claims my car is now idling smoother than his.

Now on to the tuning sessions to maximize performance!
