I noticed an oscillation at about 3500, the car standing no load, if i rev it fast it goes through all rpm range with no noticeable problems, but if I rev it slowly it oscillates between 3400 and 3500. I am happy with the daily driving performance just somewhat rich at idle. Any advices before I start messing with the map?

UPDATE!!! The oscillations were caused by launch Control. LOL At least I m figuring this ECU and its fun! I still want to lean it a bit more.
