BMW s1000rr ecu sync with cluster

[Haso]

Does anyone know how to sync the cluster with the ecu on a BMW s1000rr? I'm have used my ecu on 2 bikes and now I want to sync my cluster with the original ecu, but the mileage is blinking.

Only possible with ista as far as I know and mileage will go to the higher value

PM me please, thanks
