SOFTWARE

Firmware updates/upgrades are, despite the manufacturers advertising new features, better battery management etc., at the same time gateways for their unwanted features, which take away or limit the choice for tuning. At present, no upgrades/updates of the engine firmware should be carried out in order to preserve the choice for tuning/original condition. This also applies in particular in connection with workshop work on the e-bike.

Conclusion: If you have installed the BOSCH sensor, you now also have a great option for tuning.
