This ECU is "unlocked" and can be updated to newer RACE maps by your dealer (if newer maps become available). This ECU is pre-programmed with the official Aprilia the RACE map for use with aftermarket full system or slip-on exhausts. AF1 Racing strongly recommends purchasing this RACE ECU in if you have installed an exhaust system with no catalytic converter or a removable dBkiller. When using exhaust systems without catalytic converter but with the dB-killer installed (such as when riding on circuits with noise restrictions), using the RACE ECU is still recommended. The ECU is loaded with the three maps R, S and T, all of which full power maps. This ECU is compatible with the V4-MP / V4 AMP accessory ECU. *Please Note: Dealer installation is required, due to throttle and handle learning procedures (ride by wire re-calibration) that must be done with the Aprilia dealer only PADs diagnostic computer.
