For NB Miata owners, understanding your car’s diagnostics is crucial for maintenance and performance tuning. A key component in this process is the OBD2 port. But where exactly is the OBD2 port location on an NB Miata? Knowing this location is the first step to accessing a wealth of information about your vehicle using an OBD2 scanner.
Finding the OBD2 port in your NB Miata is typically straightforward. You’ll usually find it located under the dashboard on the driver’s side. It’s often near the steering column or in the vicinity of the fuse box. Once located, this port becomes your gateway to connecting with your car’s computer system.
Why is this OBD2 port so important? It allows you to connect diagnostic tools and scanners to read trouble codes, monitor engine performance, and even customize certain vehicle settings depending on the software and adapter you use. As mentioned in a forum discussion, there are various OBD2 adapters available, each with its own set of features and compatibility.
One popular and affordable option is the ELM327 Bluetooth adapter. These adapters, readily available online, can connect wirelessly to smartphones or other devices. Paired with the right app, like Torque for Android, or Rev for iOS, you can access real-time data from your Miata’s engine and systems.
Lol. That’s really expensive; and I’ve seen no proof that my friend’s $100+ adapter works any better than my ELM327 Bluetooth adapter, which is much much cheaper:

Need a bluetooth-compatible smartphone; then you need an app, I’m a big fan of Torque, but the Rev app is probably fine too. Not sure how they compare. Torque cost me a few bucks.
As highlighted in the forum excerpt, ELM327 adapters are a cost-effective entry point into OBD2 diagnostics. They offer a wide range of functionalities when combined with suitable software. While basic adapters can provide essential diagnostic information, more advanced options like the Kiwi adapter cater to users with specific needs, such as iOS compatibility.
I had a Elm327 BT adapter first and used it with my Windows Netbook. It worked fine, but I thought all of the software I tried was clunky. I don’t have an Android device but I do have an iPhone so the Kiwi came on board. There’s only two or three apps that work with the Kiwi/iPhone combo. Rev2 is probably the most popular. It does all the same stuff any of the Elm327 stuff will do. The one thing it does that none of the PC/Elm327 stuff does though is overlay your position on a track map using GPS. This can really help you visualize what you’re doing right and wrong. It’s not as good as a dedicated track position unit, but it does work pretty well. One thing that Rev2 is NOT so good at is the number of times it samples per second. Generally this isn’t a bad thing. But in talking to the people at DPTune they say that the resolution of the Rev2 data logging isn’t fine enough for them to feel safe about throwing an aggressive tune (worth about 14hp over stock compared to about 9hp for a standard tune) into the stock ECU. So I may have to either buy a better piece of software for the Kiwi/iPhone combo or reinvestigate the PC/Elm327 software question.
For NB Miata owners interested in performance tracking, apps like Rev2 offer features like GPS-based track mapping. This can be a valuable tool for visualizing driving performance on a track. However, it’s worth noting that for advanced ECU tuning, the data logging resolution of some apps like Rev2 might be a limiting factor, as pointed out by tuning specialists.
In conclusion, locating the OBD2 port on your NB Miata unlocks a world of diagnostic and performance monitoring possibilities. Whether you opt for a budget-friendly ELM327 adapter or a more specialized tool like the Kiwi, understanding your OBD2 port location is the first step in taking control of your NB Miata’s health and performance. Exploring the various OBD2 apps and adapters available will allow you to find the perfect setup for your needs, from basic diagnostics to in-depth performance analysis and track day insights.
