I installed my Bazzaz last year and love it. The AFM is worth its weight in gold. Having the ability to map for current real time conditions is priceless. The only gripe I have is when you run the bike with the AFM, and plug into your laptop after your run to see what the program suggest for a map tweak, if you hit "apply all" it adjusts both maps in the unit instead of the specific map you are working on. Beside that, this thing is the best thing sense bottled beer.
