    Use of the BMW AFXIED is not recommended for 2014 and later liquid cooled R1200. Field updates to the ECM by BMW Dealers during routine service department visits are creating incompatibility between the ECM and the AFXIED. The field upgrade was something beyond our control, with no know issues prior to the new ECM load occurring in late 2016. With the field upgrade slowly propagating the change, the situation was not discovered until early 2017. This resulted in our de-certification of the R1200 LC models. We are in the process of developing an updated AFXIED for these bikes. Release date to be announced at a future time. There are no known issues with the older air/oil cooled engines.
