Excellent update to the existing AF-XIED platform for BMW water cooled bikes. BMW changed the software for their engine management computer sometime in 2016. This update is applied to earlier WC bikes when serviced by the dealer. With this update, the AF-XIEDs would not function properly. With the delay box(s) installed, the system now functions as designed and offers a substantial improvement to the engine's drive-ability, response and smoothness. The delay box(s) may require an additional harness(s) to install depending on bike model.
