The stock ECU sets fueling on many more factors like temperatures, throttle demand changes, demand rate of change, pressures, etc not to forget our very advanced RBW system on the RSV4 which definitely comes into play.

Those add-on boxes are more of a fine tuning device and they have limits. They cannot alter ignition timing or any of the RBW settings. All those Parameters get changed with the RACE mapping. Full power ignition, full power RBW settings, and full power fueling. The RACE mapped ECU is the only way to change those parameters from stock.

The bottom line is you still need the ECU putting out good information to the Bazazz or Powercommander and then you custom fine tune it on a dyno or a self learning setup.
Bloody aprilia aint cheap when it comes to getting a system fitted and mapped
I would think secondhand values of akro systems will be low due to having to purchase a new race ecu to make it work right
