BMW M54 Plug and Play Adaptor

Replace the original ECU in your E46 BMW with this plug and play solution.
This controls all the standard modules in the car, including the dashboard, but makes it much easier to control a modified engine.
The ECU will have a base map loaded, but it will need to be tuned to match the engine.

This is the adaptor only. A matching ECU will also need to be purchased. We recommend a T8+ ECU, but a T12+ will also work.

This adaptor is for cars with drive by wire. If the car has a throttle cable, then please contact us first.
