There's no question I'm buying this as soon as it trickles down to Ultra distance style race mtb bikes (shorter travel ~130 front/100-120 rear). This past year I used the Quarq shock wiz to analyze and tune the shocks on my current mtb race bike it made a huge difference. Mount it to the pressure valve, ride the bike, review the results and suggestions, modify, repeat. In 2 sessions I had it riding great. The Fox system takes this up a whole nother level though and the reviews so far have been great.
I spent many time consuming hours of try and test re-valving of the Bilstein 7100s on my previous truck and Radflos on my current. In the end I got them where they were performing great, but at least having electronic data logging would make it so much quicker to dial in. I know this is in use in motorsports generally but it doesn't seem to have trickled down yet.
