Basically, it's a finished, yet limited version of what Flash Tune is doing.
Taken from your link:
Magnum Revolution Pro-II Push Button Programmable Motorcycle Rev Limiter also referred to as Motorcycle CDI Box is a special programmable Voltage-Controlled Crystal Oscillator VCXO with uniquely extended frequency range, designed to Motorcycles' ECU. This rev limiter can override RPM- & speed limit by up to 20% up or also down if necessary. This Rev-Pro rev limiter is supposed to override factory rev- and speed governor in order to get rid of suffering factory RPM or top end speed restrictions. In parallel it secondarily remaps injection timing to gain more horsepower and torque furthermore to deliver aggressive acceleration and throttle response. Magnum Rev Limiter plugs to the ECU's governor quartz. This Motorcycle ignition piggyback is available to all fuel injected Bikes. Installation is not complex but certain skill is still required.
Get rid of restrictions and achieve explosive performance levels.
Wait for ECU Unleashed or Stoltec Moto to finish their modifications and release them to the public, no sense in soldering wire or modifying the ECU in that fashion when it can be flashed to achieve the same results.
IMO the Power Commander is a better option. Ecunleashed is around $500 and you're set to one tune that they provide according to your mods. With an auto tune the price is a little higher, but you have the flexibility to tune on the fly with just about anything you would want to do. Yes there are some things you can do with a reflash that you can't do with a PC, but a proper tune is more important than anything. Making changes to increase top speed, engine braking or other things won't mean crap if you grenade your engine due to a crappy tune. I'm sure there will be a lot of flaming here, but who cares because I sure don't!
