Today, car enthusiasts are looking for different solutions to enhance their vehicle’s performance and take their driving experience to the highest level. This is exactly where we come in! As XirDecoder Chip Tuning, we specialize in engine optimization and software updates. We aim to provide our customers with the best performance and lead the industry with our advanced technologies and professional team of engineers.

We are excited to introduce XirDecoder, an innovative chip tuning platform that’s revolutionizing automotive performance with the power of AI. Whether you’re a professional tuner or a car enthusiast, XirDecoder offers a robust solution for optimizing engine and transmission control units.

Key features and functionalities

• DTC (Diagnostic Trouble Code) Removal: XDecoder allows users to disable or remove specific DTCs from the ECU, which can be useful in resolving issues related to certain sensors or components, according to OBDII365.com. This feature is also described as “DTC OFF” or “Fault Code Removal”.
• Chip Tuning/Performance Optimization: The platform enables performance enhancements by modifying parameters like fuel injection timing, turbo boost pressure, and air/fuel mixture settings in the ECU It offers solutions for Stage 1-2 tuning
• Emissions System Management: XDecoder can be used to disable or manage components like DPF (Diesel Particulate Filter), EGR (Exhaust Gas Recirculation), AdBlue, Lambda, and CAT (Catalytic Converter) systems.
• Transmission Optimization: It also offers transmission optimization features, including DSG (Direct Shift Gearbox) optimization for smoother gear changes and launch control adjustments.
• Wide Compatibility: XDecoder boasts a large database of over 130,000 files with unique DAMOS mapping technology for various vehicle makes and models
• Additionally, if the uploaded file is not original, XirDecoder will detect non-original maps such as DPF or EGR and notify you. If desired, you can convert only the DPF and EGR maps back to their original state

How it works

• Read ECU File: A master device is used to read the ECU’s file from the vehicle.
• Upload to XDecoder: The read file is uploaded to the XDecoder software platform.
• AI Analysis and Optimization: The platform’s AI analyzes the file and suggests tuning options, or you can select specific modifications.
• Download Modified File: The system processes the file based on the selected options and provides the modified file for download.
• Write to ECU: The modified file is then written back to the ECU using a suitable device

Considerations

• Legality: The legality of modifying emission systems (like DPF, EGR, AdBlue) may vary by region and can have serious environmental and legal consequences. It’s crucial to understand and comply with local regulations before considering such modifications.
• Risks: ECU tuning carries inherent risks, and improper modifications can potentially damage the engine or other vehicle components.
• Support: XDecoder provides support for its users, including a system for creating support requests and chat with tuners
• Software Activation: The software license is activated online and is linked to a specific computer.
• Renewal Fees: Annual renewal fees may be required to maintain account activation.
