**UNLOCK CODES – To get your unlock code after purchasing this product, we will need your VIN and ECU serial #.  The serial # can be obtained physically by taking a picture of the bottom layer Magnetti-Marelli sticker on the ECU itself, or electronically with GuzziDiag or the Aprilia diagnostic computer  (AKA PADS) software.  

Reply to any of your Akra pipe order emails with your VIN and ECU serial #, during our normal business hours and we will typically reply with the unlock code within two hours.

Your dealer will use their PADS and that unlock code to load RACE mapping.  That allows the proper RACE mapping to be installed with dealer software.

If you have no dealer, we can input the RACE mapping code you by mail-order.  Ride by wire re-calibration will still have to be performed. GuzziDiag is a popular way for the home user to recalibrate the Ride-by-Wire.
