ive had VERY few problems with uberdata. and ive noticed the more familiar i got with the program the less bugs it seemed to have. most programs have slight bugs in it. i know hondata has had quite a few as ive learned from first hand experience, even aem ems has bugs in it, its just part of the game and working around the bugs to fit the needs of each car. all the systems work great and im sure if uberdata had the financial backing that hondata had it would have some of those better features that hondata possesses, but it doesnt, and thats why its free. just make sure whoever tunes your car is confortable and familiar with the system that both of u choose and u should not have any problems.
