it has taken me a hour, but I finally found the golden egg answer.... I have seen too many people associate Race 1 and Race 2 with what is called Race 3 Kit, but this is completely wrong.
BMW HP Race Calibration Kit 3
Part number : 77 53 8 546 642
is a complete rework for the 2015 and what should be beyond, because the ECU is completely all new. It is the new microprocessor Bosch ECU controller.

Details
The HP Race Calibration Kit can be used to customise the following parameters of the engine management system and DTC (see the user guide for details):
Fuel injection quantity and ignition timing:
Allowing for track-specific ambient conditions such as relative humidity.
Custom adaptations to allow for modified powertrain components such as exhaust system, air intake ducting and camshafts.
Custom adjustment of response in accordance with rider preferences and track profile (engine power and power development).
Traction control:
Adjustment of tyre parameters such as circumference, shape and slip to customise the response of the DTC system (control timing/rate).
Mode-dependent definition of an angle of heel below which traction control is deactivated to permit wheelies.
Total of 9 characteristic maps for adjustment.
Custom settings possible for each individual riding mode (Rain, Sport, Race and Slick). Shift response of the HP shift assistant (OE/OA):
Adjustment of intervention speed (torque build-up after gearshift). Speed limiter for the pit lane:
Maximum engine rpm for 1st gear with starter button pressed. Delete adaptation values:
Restore adaptive parameters of the engine management system to the default settings. Adaptation values are settings that the engine management system "learns" automatically to allow for certain motorcycle components such as the throttle-valve assembly and the exhaust system. If the components in question are changed the adaptation values have to be deleted so that the ECU of the engine management system can learn the new values for the modified or new components.
