dAHLer’s Engine Performance Tuning Module for the G29 Z4 M40i and A90 Supra 3.0 Turbo is a formidable tool in adding horsepower and torque to the B58 engine.

Developed in Switzerland and made in Germany – dAHLer’s module is the perfect tuning tool for vehicles with locked ECUs of any age! It integrates flawlessly to extract maximum power and torque without faults and errors. The harness has OEM style plugs to connect in-line with each boost pressure sensor, camshaft position sensor and rail pressure sensor on the engine.

Controlling of the dAHLer Engine Performance Upgrade via your smartphone is just one of the awesome features of this tuning module. With dAHLer’s tuning module you have the option to choose your own and 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 free updates are released. If desired the extra power can be easily switched on or off with your smartphone, even while driving. The dAHLer app includes a configurable warm-up timer, so the driver can decide how long warming up is needed before using the engine tuning. A separate Mobile app purchase is not required.

dAHLer’s Engine Performance Tuning Module is completely reversible to OEM specs and installs in less than 1 hour just in a few simple steps. This is a safe upgrade which is the easiest and most effective power upgrade you will ever make on your new M240i. Inside the dAHLer Engine Performance Tuning Module is an advanced control unit that is 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.

If BMW updates the computer software of the vehicle, this Engine Performance Tuning Module is not lost or overwritten. This is where competitor tuning modules fall short! This is just another key aspect of our module because BMW is constantly releasing small software updates. All of the factory diagnostics and service access is retained. The dAHLer Module is undetectable to plug-in diagnostic readers and it leaves no traces behind. 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.
