Description
Unleash the full potential of your BMW B58 engine with the dAHLer Engine Performance Tuning Module, engineered in Switzerland and manufactured to the highest standards in Germany. This advanced plug-and-play power upgrade is designed to deliver seamless integration with your factory ECU, enabling substantial horsepower and torque gains—up to 56 horsepower at the wheels on a stock vehicle—without triggering faults or error codes.
Unlike traditional tuning methods that require DME removal or permanent alterations, the dAHLer module uses a direct in-line connection with OEM-style plugs at the boost pressure and camshaft position sensors, along with appropriate 12V power and chassis ground connections. The entire installation process takes less than an hour and is fully reversible, allowing you to restore your vehicle to stock at any time.
Control the tuning module wirelessly via your iOS or Android device using the free dAHLer mobile app. Through the app, you can choose between three distinct performance maps, update firmware remotely, toggle performance on or off in real-time, and configure a warm-up timer to delay power delivery until the engine reaches optimal operating temperature.
This tuning solution is fully compatible with all factory drive modes and retains smooth drivability, emissions compliance, and factory diagnostics. With no impact on fuel economy during normal driving and features like a valet plug to instantly revert to factory settings, this tuning module provides the perfect balance of power, safety, and convenience.
