Hi, peeps! As you know, I am an auto enthusiast, I follow a lot of tech-auto blogs to learn about new stuff in the market. Recently while surfing the auto section on Amazon India, I came across this ELM 327 OBD-II Bluetooth scanner. Despite the crude presentation and item listing, it piqued my interest and I decided to research about it.

What is ELM 327 OBD Bluetooth scanner?

Post research, I was able to infer that:

Now, I have had already researched about the position of OBD port in my car (Toyota Etios), which was on the lower right side of driver’s cabin, so it took me less than 60 seconds to get it to fit. It’s a unidirectional port, much like a VGA port. The scanner powers on immediately upon plugging, suggesting it takes an uninterrupted current from the battery.

Companion app(s):

Post plugging the scanner, I downloaded Torque and OBD Car Doctor as they are the top rated apps for the diagnosis and went out for a night ride with a friend to take screenshots. We went for a short run and both of us were mesmerized by the quantity & quality of data you can using this nifty little tool. It’s amazing how the response time in a few milliseconds.

Torque is a better-rated app but I found OBD Car Doctor to be more intuitive both in terms of UI & UX. Here are some screenshots for you to validate the same:

Verdict:

ELM 327 OBD-II Bluetooth Scanner is a really cheap and value for money microcontroller produced by ELM Electronics for translating the on-board diagnostics (OBD) interface found in most modern cars.

You can even inspect the error codes yourself to know in and out of your machine. It can be really helpful from knowledge purpose as well as to prevent you from getting duped from car mechanics.

Straight out of Minority report?! 😉

ELM 327 relies on your smartphone’s display to show up the data, though if you are more interested, you can also invest in these cool looking HUD – Head Up Display which will sit on the dash of your car and project data straight to the windshield. They look really cool, especially in the night. 😎
