The Dimsport Mygenius OBDII ECU Tuner is a renowned tool in the automotive world, empowering you to effortlessly tune or detune your vehicle. This comprehensive guide provides a step-by-step walkthrough of the ECU tuning process using the Dimsport MyGenius, specifically focusing on flashing a Mercedes Benz C63 W205 with a VR Tuned ECU flash.
Preparing for the Tune: Updating and Connecting
Before starting, ensure your Dimsport MyGenius device is updated with the latest software by connecting it to a Windows 8 (or newer) PC. A crucial step is connecting a battery charger to your vehicle throughout the process, as ECU tuning demands significant power. We maintained a constant 12 volts on our C63 during the procedure. Turn on your vehicle’s accessories to power the ECU tuner and then connect the Dimsport MyGenius to the OBDII port.
Reading Your ECU’s ID: A Crucial First Step
Navigate to the “Work” menu on the MyGenius device and select “PRT Identify.” Choose the “ID” option to read your ECU’s unique identifier. Once the device displays “Task completed Successfully,” turn off your vehicle and disconnect the device. Connect the MyGenius to your computer and open the MyGenius client software. Click “Download from MyGenius” to extract the ID file and save it to your desktop. This file will be used to create your custom tune file.
Obtaining and Uploading Your Custom Tune File
Upload your saved ID file to VR Tuned (link provided in original article). We will modify your file to optimize performance and return it to you within 24 business hours during typical weekdays. The returned file will include both your stock and tuned files, allowing seamless switching between them. Upon receiving the modified file, open the MyGenius software and click “Upload to MyGenius,” following the on-screen instructions to transfer the files to your device. This ensures both the original and tuned versions are available on the MyGenius.
Flashing Your ECU: The Transformation Begins
Reconnect the MyGenius to your car with the accessories turned on. Access the “Work” menu and select the VR Tuned modification. This writing process takes approximately 15 minutes and involves several ignition cycles. Caution: Interrupting this process can potentially damage your ECU. After successful completion, start your vehicle and check for any warning lights. If all is clear, you’ve successfully tuned your car!
Enjoying and Managing Your New Tune
Allow your engine to warm up and experience the enhanced performance. A quicker rev climb is a common indicator of a successful tune. To revert to your stock tune, simply reconnect the MyGenius and follow the same steps, selecting the stock file instead. The Dimsport MyGenius can store up to ten tune files, offering flexibility for future modifications.
Conclusion: The Power of Dimsport MyGenius
The Dimsport MyGenius OBDII ECU Tuner is a user-friendly and powerful tool for enhancing vehicle performance. Its ease of use, combined with extensive online support and the ability to hold multiple tunes makes it an excellent choice for both beginners and experienced tuners!
