aswell can somebody look at my datalog here and confir, that my mapdot looks allright ? actually looks pretty noisy to me.. but I cant tell whether it is mechanical or electrical noise... jumps durning idle normally +-10, but sometimes like +-15... if my map AE treshold is 20 then it is often falst triggered... best if I set it up that mapdot treshold to 40....
