If you’re using an OBD2 Bluetooth adapter with apps like Torque Pro to monitor your car’s performance or diagnose issues, you might want to be aware of something important: pirate or cloned versions of these adapters. It’s a common issue, and you might unknowingly be using one right now.
These clone adapters often mimic popular devices like the ELM327, which is a microcontroller at the heart of many OBD2 tools. According to Wikipedia and experiences shared by users, early versions of the ELM327 chip were copied, leading to a proliferation of “pirate” OBD2 adapters in the market.
The problem with these clones isn’t just about ethics; it’s about functionality and reliability. These pirated adapters are often based on outdated and bug-ridden versions of the original ELM327 firmware, specifically version 1.0. Even worse, they frequently misreport their version number, sometimes claiming to be a non-existent “Version 1.5” or even later, to appear more legitimate. In reality, their capabilities are limited to those of the very first, and flawed, ELM327 version.
Many users who purchase inexpensive OBD2 Bluetooth adapters online, especially from large marketplaces, may unknowingly receive these clones. They might seem to work initially, connecting to apps like Torque and providing some data. However, you might encounter inconsistencies, limited functionality, or even incorrect readings because of the outdated and potentially buggy firmware within these pirate devices.
If you suspect you have a clone, especially if your adapter reports “Version 1.5,” it’s a strong indicator. ELM Electronics, the creators of the ELM327 chip, have never released a version 1.5. This misleading version number is a hallmark of many fake adapters.
While incredibly affordable OBD2 Bluetooth adapters might seem tempting for use with Torque and similar apps, the potential issues with pirate versions are something to consider. For reliable car diagnostics and accurate data, especially when using apps that depend on consistent OBD2 communication, it’s worth being cautious about extremely cheap adapters and verifying the source if possible. Unfortunately, distinguishing between genuine and fake units can be difficult, highlighting the importance of purchasing from reputable sources when acquiring your OBD2 Bluetooth adapter for use with apps like Torque Pro.
