Encountering issues connecting your BAFX Bluetooth OBD-II reader to your ’99 Miata can be frustrating, especially when it works perfectly on another vehicle like a ’98 Civic. Many Miata owners, particularly those with NB models (1999-2005), sometimes face unique challenges with aftermarket OBDII readers. Let’s explore common questions and potential solutions to get your BAFX reader working or help you decide if exploring other options, possibly a “Bafx Obdii Reader For Sale,” is the next step.
One common concern revolves around compatibility. While OBD-II was standardized in 1996, subtle differences in implementation across car manufacturers and models can lead to connectivity hiccups. You’re right to question if the ’99 Miata has specific protocol needs compared to your Civic. It’s unlikely you need to manually specify a protocol initially, as most readers, including BAFX, are designed to auto-detect. However, this is something we can revisit if initial troubleshooting steps fail.
Another point of confusion often arises with the location of the OBDII port itself. You mentioned finding a port under the fuse box cover to the left of the driver’s knee. While this is indeed an access point, the actual OBDII port on the ’99 Miata is typically located lower in the driver’s side footwell, often near the steering column. Mechanics usually access it from this lower position, which might be what you observed. Using the port under the fuse box cover might be inconvenient for prolonged use with devices like trip meters, and it’s worth double-checking you’re using the correct, standard OBDII port underneath for reliable connection.

Regarding your concern about NB Miatas being particularly picky with OBDII readers, it’s a valid point. While BAFX readers generally receive positive reviews for their compatibility, some vehicles can be more sensitive. Before considering a “bafx obdii reader for sale” and switching brands, let’s try a few more troubleshooting steps. First, ensure you are indeed connected to the lower OBDII port in the footwell. Try different OBDII apps besides Torque and Car Gauge Lite; some apps might handle protocol negotiation slightly differently. If you still encounter “No response from vehicle ECU” errors, even after verifying the port and trying alternative apps, then the issue might be reader-specific compatibility with your Miata.
In conclusion, while your BAFX reader works on your Civic, its lack of connection with your ’99 Miata could stem from the port location or specific Miata compatibility nuances. Double-check the OBDII port in the footwell, experiment with different apps, and if problems persist, exploring other OBDII reader brands or considering a “bafx obdii reader for sale” might be necessary to find a reader that reliably communicates with your NB Miata’s ECU.
