Converting your older Mitsubishi to OBD2 opens up a world of possibilities for advanced engine diagnostics and tuning. While Mitsubishi’s tuning scene might not be as straightforward as some other makes, several viable options exist to bring your vehicle’s capabilities into the modern era. Let’s explore how you can equip your Mitsubishi with OBD2 and delve into the tuning potential it unlocks.
Option 1: BlackStealth MUT to OBD2 CANBUS Converter
For Mitsubishi owners primarily interested in data logging, the BlackStealth MUT to OBD2 CANBUS converter is an excellent plug-and-play solution. Specifically designed for older Mitsubishi models, this converter bridges the gap between your car’s MUT (Mitsubishi Unique Transfer) system and standard OBD2 protocols. By simply plugging in this device, you gain the ability to use popular OBD2 logging tools like Torque on your Android or iOS device. Beyond basic logging, the BlackStealth converter also accommodates additional inputs for external sensors such as wideband oxygen sensors and boost pressure, expanding your data acquisition capabilities. While tuning with this option typically involves piggyback systems, the enhanced logging provides a solid foundation for optimizing your engine’s performance.
Option 2: Chrome ECU Swap for Plug-and-Play OBD2
If you’re looking for a more comprehensive solution that facilitates both OBD2 logging and advanced tuning, swapping to a Chrome ECU is a highly recommended path. Chrome ECUs, readily available from specialized vendors, are engineered for easy installation in various Mitsubishi models. This swap provides native OBD2 functionality, eliminating the need for converters for basic logging. The Chrome ECU is pre-configured for your specific vehicle, ensuring a straightforward plug-and-play experience. This option simplifies the process of accessing and interpreting engine data, making it significantly easier to monitor performance and diagnose issues.
Option 3: ’99 ECU Swap with Custom Harness
For the technically inclined and budget-conscious Mitsubishi enthusiast, retrofitting a ’99 ECU offers another route to OBD2 compatibility. This method involves sourcing a ’99 Mitsubishi ECU and creating or purchasing a custom wiring harness to integrate it into your older vehicle. While potentially more cost-effective in terms of parts acquisition, this approach demands a greater degree of technical expertise and time investment in wiring and configuration. Successfully implementing a ’99 ECU swap provides similar OBD2 logging and tuning capabilities as the Chrome ECU, but with a steeper initial learning curve and installation process.
Unleashing Tuning Potential with OBD2
Regardless of the OBD2 conversion method you choose, upgrading your Mitsubishi unlocks access to powerful tuning capabilities. Chrome ECUs, in particular, open doors to advanced features beyond simple piggyback tuning systems. These include functionalities like launch control, ECU-controlled boost management, support for larger fuel injectors (essential for E85 fuel), and the inherent safety features of the stock ECU.
To fully leverage these tuning capabilities, you’ll need appropriate logging and tuning tools. EvoScan for PC is a popular choice for comprehensive data logging, and when combined with BlackStealth’s converter, it provides in-depth insights into your engine’s operation. For tuning itself, ECUflash software, coupled with an Openport 2.0 cable, is commonly used to flash and modify ECU maps. While self-tuning requires a commitment to learning and understanding engine management principles, abundant resources and guides are available, including those from the Mitsubishi and Evo communities, to assist you in mastering the process.
In conclusion, upgrading your Mitsubishi to OBD2 is a worthwhile endeavor for enthusiasts seeking enhanced diagnostic and tuning capabilities. Whether you opt for the simplicity of a converter, the plug-and-play convenience of a Chrome ECU, or the DIY approach of a ’99 ECU swap, the benefits of modern OBD2 access will significantly improve your ability to monitor, maintain, and optimize your Mitsubishi’s performance.
