The dynojet really has a solid product. If you take it to a official "Dynojet" shop, you put your bike on a dyno with all your aftermarket goodies and they dial in the FI for your specific bike. From my understanding most factory bikes run a bit fat on the fuel so generally after you get it mapped it will be leaner but will be optimal for your setup. They will have some maps you can download from the website which will have different setups that will be considered the most "popular".
Hopefully there will be a timing adjustment within the 3 demensions of the map. We were tuning a buell a while back and found that Harley was using only about 3 degrees of timing at idle, thus making the motor lope and giving it a nice rough idle. That's about the only gripe I have with this motor is with louder pipes the idle is so smooth it doesn't really match the bike.
