Electronic Box Engine Control Module by Rbw Skull

The RBW SKULL Engine Control Module is a plug-and-play electronic box designed for EURO5 and EURO5+ motorcycles equipped with a competition exhaust system. Its integrated Autotune helps prevent the engine warning light from activating due to the exhaust, while maintaining the lambda sensor behaviour and original safety parameters.


Design and Materials

  • Designed for EURO5 and EURO5+ motorcycles, the module supports the installation of a competition exhaust system on the relevant generations.
  • Designed and tested in Italy by a manufacturer certified to IATF 16949 and ISO 9001, the module benefits from an identified manufacturing framework.

Installation and Mounting

  • The OEM plug-and-play connection is completed in seconds to reduce installation time.
  • No reprogramming of the ECM is required, simplifying the commissioning of the module.
  • Two connection versions are identified to match the configuration present on the motorcycle.
  • The version 10204267 uses a red DLC connector with a lambda sensor downstream of the catalyst.
  • The version 10204268 uses an OBD2 connector.
  • Sold individually.
  • Manufacturer reference SN25HONDA00

Usage and Performance

  • The integrated Autotune adjusts the module's operation to support the installation of a competition exhaust system.
  • The exhaust signal management prevents the engine warning light from activating due to the installed system.
  • The lambda sensor behaviour is maintained to preserve the intended operation of the injection system.
  • The safety features related to RPM, the limiter, and emission parameters remain unchanged to retain the relevant settings.

Safety and Standards

  • Usage exclusively reserved for track and competition.
