Developed in Switzerland and quality Made in Germany – The tune works with cars before and after production 06/2020! The Engine Performance Tuning Module for the BMW B58 integrates flawlessly to extract maximum power and torque without faults and errors – just flawless. The harness has OEM-style plugs to connect in line with each boost pressure sensor and the camshaft position sensor on the engine.

Controlling the dAHLer Engine Performance Upgrade via your smartphone is just one of the excellent features of our tuning module. With our tuning module, you can choose your own fully customizable driving program. Wirelessly connect the dAHLer engine tuning performance module to your Bluetooth 4.0 compatible iOS and Android device via the free dAHLer Mobile app.

This option allows you to change 3 different performance maps, and update the firmware worldwide as we release free newer versions with updates, and more powerful maps. If desired, the extra power can be easily switched on or off with your smartphone, even while driving.

Our app includes a configurable warm-up timer, so the pilot can decide how long warming up is needed before using the engine tuning. A separate Mobile app purchase is not required!

Our Engine Performance Tuning Module for the BMW B58 is entirely reversible to OEM specs and installs in less than 45 minutes, just in a few simple steps. This will be a safe upgrade which makes this the easiest and most effective power upgrade you will ever make on your BMW. For a substantial increase in power output, with minimal downtime for installation, complete serviceability, and can be reverted back to stock, this Engine Performance Tuning Module power upgrade is best!

Inside our dAHLer Engine Performance Tuning Module is an advanced control unit designed to optimize and work with the factory BMW ECU. The BMW B58 maps and algorithms within the control unit have been elevated for this BMW engine, sending improved fuel and ignition parameters to the stock ECU to control boost depending on load, engine speed, and other factors.

Also included in the scope of delivery is an adapter that, when installed, returns the vehicle to its original state without having to remove the cable harness of the dAHLer engine performance upgrade. This can be used, for example, at a workshop appointment.

If BMW updates the computer software our Engine Performance Tuning Module is not lost or overwritten. This is where competitor tuning modules fall short! This is another critical aspect of our module because BMW constantly releases small software updates. All of the factory diagnostics and service access are retained.

The dAHLer Module is undetectable to plug-in diagnostic readers and leaves no traces. A valet connector is included and installs in minutes to bypass the Module and revert the car to factory settings. With the valet plug installed, the BMW engine computer will use the stock maps instead of getting modified data from the Engine Performance Tuning Module.
