Step-by-Step Installation Process
Step 1: Prepare Your Vehicle
Before starting the installation, ensure your BMW 335i is parked on a flat surface and the engine is turned off. Gather all the tools and materials you will need for the process.
Step 2: Connect the Tuner
Locate the OBD-II port in your BMW 335i, usually found under the dashboard near the steering column. Plug the tuner into the OBD-II port securely.
Step 3: Power Up the Tuner

If your tuner requires software installation on a computer, follow the manufacturer’s instructions to download and install it. Connect the tuner to your computer using the USB cable if necessary.
Step 5: Upload the Tune
Using the software, select the appropriate tuning options for your BMW 335i. Upload the tune to the vehicle’s ECU. This process may take a few minutes, so be patient and do not turn off the ignition during this time.
Step 6: Disconnect the Tuner
Once the upload is complete, disconnect the tuner from the OBD-II port. Ensure all connections are secure and tidy.
Step 7: Test Drive
Start your BMW 335i and take it for a test drive. Pay attention to the vehicle’s performance, acceleration, and any changes in engine behavior. Make adjustments as necessary based on your driving experience.
