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.

Waste of money. Cheap clone of real ELM 327 module. Not work on all vehicles. My scanner died just after a single scan. Totally garbage.

Nice product good working little bit advertisement

Very useful and compact diagnostic tool for car owners. The Bluetooth connection was quick to set up, and it worked smoothly with the Torque app on my Android phone. I was able to check engine parameters, read error codes, and monitor real-time vehicle data without visiting a service center. The device is small, easy to carry, and offers excellent value for money. Highly recommended for anyone who wants to keep an eye on their car’s health.

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!!

Initially Torque Pro (already installed condition in Android Head Unit) was not able to connect to MCU of Maruti Spresso. I uninstalled above. Identification of website was done through QR code given on ODB2 and the same was typed on chrome on Android Head Unit. Downloaded from website (not from Play Store) and installed. It started working flawless. But it was observed, it will be on evenafter ignition key is removed and reduced battery level by 0.1v in 12 hours. Hence i returned as it has no Auto sleep. Instead of refund they sent another, but this time it is not getting on. Returned. I may go for obd2 with Auto Sleep function so no need to remove from socket.

The product does relay all sorts of information that can be useful for a diagnosis. Although further consultation could be required. For example for a 2011 hyundai, spark plugs were misfiring but the scanner didn't show any warnings or errors possibly because the car's ecu didn't register it or the scanner was unable to understand the information. So I still had to rely on intuition and engine behavior.
