The freely configurable A.E.B. MP48 OBD Set is the further development of the established AEB2001N system. It is suitable for all 3-4 cylinder engines with sequential injection.

The compactly built control unit is easy to install even where space is limited.

During operation, the control unit measures the injection times and the gas pressure and calculates the optimal dosing time and quantity.

A diagnostic system is integrated in the control unit of the A.E.B. MP48 OBD itself, which monitors the function and status of the other gas components during installation and operation. The results can be called up via the calibration software. This option can prevent malfunctions and facilitates troubleshooting and error correction.

The calibration tool provides instructions to simplify system installation and setup.

You can download the installation instructions free of charge.
