Description
Unlock the full potential of your BMW with the dAHLer Engine Performance Tuning Module for N55 engines—a precision-engineered solution that delivers increased horsepower, torque, and control while maintaining factory reliability and drivability. Designed for a wide range of BMW models equipped with the turbocharged inline-six N55 engine, this tuning module is the ultimate plug-and-play upgrade for enthusiasts seeking noticeable performance gains without compromise.
Crafted in Germany and developed in Switzerland, the dAHLer tuning module integrates seamlessly with the factory ECU, delivering up to 9 horsepower gains to the wheels on a stock configuration. This tuning module works with BMW vehicles built before and after the production update of June 2022, and requires no DME removal or permanent modification. It connects directly via OEM-style plugs to the boost pressure sensors and camshaft position sensor, ensuring fault-free operation and simple installation in under 45 minutes.
Designed specifically for BMW models with the N55 engine, this includes a broad array of performance-oriented vehicles such as the BMW M2, 335i, 435i, 535i, and more. Whether you're driving a coupe, sedan, convertible, or SAV, the dAHLer module adapts to your model with full compatibility across all driving modes.
Control is at your fingertips thanks to the dAHLer Mobile App, which connects via Bluetooth 4.0 to your iOS or Android device. You can instantly toggle between three customizable performance maps, adjust the engine warm-up timer, or turn the tune on or off—even while driving. The firmware is updateable via the app, so your module evolves with future enhancements and power maps at no additional cost.
The module is completely reversible. A supplied adapter allows your vehicle to revert to OEM behavior without removing the harness, ideal for dealer visits or diagnostic work. A valet plug is also included, enabling quick bypass of the tune by reverting to factory settings. Unlike many tuning solutions, the dAHLer module is undetectable by standard diagnostic tools and unaffected by BMW software updates—preserving your upgrade across service intervals.
Whether you're carving corners in your M2 or adding excitement to your daily commute in a 335i, the dAHLer module transforms your BMW into the ultimate driving machine—just as it should have come from the factory.
