a lot less of a pain then the doebeck!
Its actually rather simple. You download the map for your setup...you connect the PCIII to the laptop and upload it to the unit. DONE.
OR, when you order it from fuel moto, they can install the map that best suites your mods and activate the accel pump feature.
If you run it and still want to tune it better you can plug it back into the computer, and adjust in 250RPM increments where you think it needs to be changed. OR you can just highlite a whole section and increase/decrease by 2% or whatever you want.
With the PCIII you can also utilize the ignition module that is suppose to be coming out soon.
If money isnt a problem you should totally go with the PCIII
