For owners of the Mitsubishi 3000GT and Dodge Stealth (3si), upgrading from the older OBD1 system to OBD2 can unlock significant benefits, especially when it comes to modern engine diagnostics and tuning. While not as straightforward as on some other platforms, converting your 3si from OBD1 to OBD2 is achievable and opens up a range of possibilities. This guide will walk you through the options available to make this transition and enhance your car’s capabilities.
Understanding OBD1 and OBD2 in Your 3si
OBD1 (On-Board Diagnostics 1) was the early standard for vehicle diagnostics, while OBD2 is the more modern and comprehensive system mandated in later vehicles. For 3si models produced before 1996, they came equipped with OBD1. Upgrading to OBD2 isn’t just about having a newer system; it’s about gaining access to enhanced data logging and tuning potential that OBD2 offers.
