Super Mini ELM 327 V2.1 OBD2 Bluetooth Auto Car Scanner Diagnostic Tool OBD Interface OBD Reader

I bought this Super Mini ELM 327 V2.1 OBD2 Scanner to fix a high RPM issue on my Maruti Suzuki Celerio VXI (2019), and it worked perfectly! The Issue: After I cleaned the throttle body myself, my car's idle RPM shot up to 1.2 - 1.4. The car was jerking at low speeds, and the exhaust manifold was getting red hot due to the high idle. Manual reset methods (battery disconnect/key cycles) did not work for me. The Solution: I connected this OBD2 scanner and used the Torque Pro app. I forced an error code by disconnecting the throttle body coupler while the engine was running. I used the app to "Clear Fault Codes." I heard a crackling noise from the throttle body (which meant it was calibrating). After a restart, the issue was 100% resolved! The Result: Idle RPM: Perfectly stable at 700-750 RPM. Drive Quality: Very smooth idling and no more jerking. Performance: The throttle response is now very sharp and much better than before. Savings: It saved me a lot of money and a trip to the authorized service center. I did the reasearch online and chat gpt and other AI were recommended v1.5 of this tool, I still decided to ahead with this V2.1 and it solved my issue in 10 minutes. If you don't know much, I recommend you to visit local garrage.

The most critical issue is connecting the device—it fails almost every time. Even after repeated attempts, it only connects occasionally, sometimes just once after an hour of trying. Additionally, the Bluetooth passwords 0000 and 1234 are rejected as incorrect.

Nice product good working little bit advertisement

Worked with my Triumph Tiger 800 got engine error codes. And also can read a whole lot of values from ECU. Cannot access the advanced triumph specific controls or change anything. But for 300 Rupees what can you ask for..

Why did you pick this product vs others?: Cheap and works good. I purchased it for my Nexon EV and it does work for electric cars. The details on battery, power usage, temperature, cell voltage and all is great. Connectivity: Connects via Bluetooth with the app in your phone. Works with most app. Fit: Size is small and can fit inside the fuse box and can be closed again. Red blue green lights lit up on power, connection and data transfer. Leave it plugged in into the OBD port of the car for a few hours and it will drain your battery DEAD! I had to call the RSA to jump start the car!!

My Ford Figo 2012 was showing the engine check warning. With this connector, was able to scan and clear the warning. Initially had difficulty in connecting to Bluetooth but tried with the settings from the app (sharing the app details in the pic which worked well for me) and was able to connect and scan and clear the alarm.

Really nice product. Just connect with the app, it will give all the error details. Just make sure if device has no indicator light then it will not connect. When I ordered this 1st delivery product don't have indicator light, maybe it's faulty. But when I get replacement item it's working fine.

The scanner doesn't work on my tata tigor. Tried replacement but still doesn't work. Suggestion: tata owners avoid buying this product as i have tried all tip and tricks from high and team bhp but doesn't seems to work. The adapter gets connected to phone but doesn't read the ecu.
