For owners of older vehicles still running on OBD1 systems, the desire to access modern diagnostic and tuning capabilities is understandable. While OBD1 served its purpose in early automotive diagnostics, OBD2 offers a standardized and significantly more advanced platform. If you’re looking to bring your older car into the modern era of engine management, converting to OBD2 might be on your radar. However, the path to Obd1 Obd2 Conversion isn’t always straightforward, especially when it comes to tuning. Let’s explore the options available for upgrading your system.
Exploring Your OBD1 to OBD2 Conversion Choices
When it comes to obd1 obd2 conversion, you have a couple of primary routes to consider, each with its own set of advantages and considerations. Your choice will largely depend on your goals, whether you’re primarily focused on enhanced data logging or if you’re also aiming for advanced engine tuning capabilities.
Option 1: The BlackStealth MUT to OBD2 Converter for Logging
If your main objective is to gain access to OBD2-compatible data logging tools, the BlackStealth MUT to OBD2 CANBUS converter presents a viable solution. This converter acts as an intermediary, translating the MUT (Mitsubishi Unique Transfer) protocol from your OBD1 system into the standardized OBD2 protocol. This allows you to utilize popular OBD2 logging applications like Torque on Android or iOS devices to monitor your engine’s performance.

This option is particularly appealing for those who want to keep tabs on engine parameters without delving into complex ECU modifications. Furthermore, the BlackStealth converter often includes provisions for integrating external sensors, such as wideband oxygen sensors or boost gauges, expanding your data acquisition possibilities. However, it’s important to note that this solution primarily focuses on logging and doesn’t inherently unlock advanced OBD2 tuning capabilities. Tuning with this setup is typically achieved through piggyback systems, which intercept and modify signals to the factory ECU.
Option 2: ECU Swapping for Comprehensive OBD2 Functionality
For those seeking full OBD2 functionality, including advanced tuning alongside logging, swapping your OBD1 ECU for an OBD2-compatible ECU is the more comprehensive approach. Two main paths exist within this option:
- Chrome ECU: The Chrome ECU, often available from specialized vendors, is designed as a plug-and-play solution for obd1 obd2 conversion. These ECUs are pre-configured for specific vehicle models, simplifying the installation process and providing immediate OBD2 logging and tuning capabilities. The Chrome ECU is often favored for its ease of use and pre- настроенный nature, making it a relatively straightforward upgrade for those less comfortable with wiring modifications.

- ’99 ECU Swap: Alternatively, a more budget-conscious approach involves sourcing a ’99 ECU (or an ECU from a compatible OBD2 vehicle) and creating a custom wiring harness to integrate it into your older car. This method requires more technical expertise, particularly in automotive wiring, but can be more cost-effective for those willing to invest the time and effort. Regardless of whether you choose a Chrome ECU or a ’99 ECU swap, both options typically involve running Chrome firmware, which unlocks a wide array of tuning possibilities beyond basic piggyback systems.
Tuning and Logging Post-Conversion
Once you’ve completed your obd1 obd2 conversion, the landscape of engine tuning and data logging opens up significantly. With either a Chrome ECU or a ’99 ECU setup, you gain access to advanced features not typically available with OBD1 and piggyback configurations. These features can include:
- Launch Control: Optimize your launch for improved acceleration.
- ECU Controlled Boost: Precisely manage boost levels directly through the ECU.
- Larger Injector Control (E85 Compatibility): Accommodate larger fuel injectors for higher horsepower builds and alternative fuels like E85.
- Enhanced Safety Features: Leverage the built-in safety protocols of the stock ECU, often improved in OBD2 systems.
To fully utilize these capabilities, you’ll need appropriate logging and tuning tools. EvoScan for PC is a popular choice for data logging, while BlackStealth’s converter can also provide logging functionality. For tuning, ECUflash software, combined with an Openport 2.0 cable, is commonly used to flash and modify your ECU’s software. It’s important to acknowledge that DIY ECU tuning has a learning curve. However, resources are readily available, including guides from Chrome ECU developers and information from the broader Evo tuning community. Merlin’s Flash Guide is also a valuable resource for understanding ECU flashing and tuning principles.
Conclusion: Choosing the Right OBD2 Conversion Path
Deciding on the best path for obd1 obd2 conversion hinges on your specific needs and technical comfort level. If logging is your primary concern, the BlackStealth converter offers a relatively simple and cost-effective solution. For those seeking comprehensive OBD2 functionality and advanced tuning capabilities, ECU swapping with a Chrome ECU or a ’99 ECU provides a more robust upgrade path. Regardless of your chosen method, upgrading to OBD2 unlocks a new realm of diagnostic and performance tuning possibilities for your older vehicle.
