NDesign - B58 Valvetronic Locker

NDesign B58 Valvetronic Locker is a valvetronic shaft locking device for BMW B58 engines, designed to mechanically lock valvetronic shaft in its fully raised position.
This part locks the valvetronic shaft at its uppermost position, which is required when replacing factory engine control unit with a standalone/aftermarket ECU — such as Link, Motec, ECUMaster, or similar. These controllers do not manage Valvetronic mechanism, so it must be mechanically fixed in a single position for the engine to run correctly.

Includes / Notes:
 1. O-rings are included to prevent oil leakage at installation point.
 2. The valvetronic shaft itself is not included — you'll need to remove it from your old, factory valvetronic motor and use it together with this locker.

Important:
This part is intended exclusively for engines running a standalone/aftermarket ECU (Link, Motec, ECUMaster, etc.). Do not use this locker on an engine with the factory engine control unit — it will disrupt the normal operation of the Valvetronic system
