Choosing the Best ELM327 Interface

Do you want a ELM327 interface that is cheap, simple to use, and gives you all the live data and faults you need to identify your car’s issues fast?

We spend a lot of time researching different ELM327 interfaces to discover the best one. We wind up with either a scanner that damages the car’s ECU due to being a FAKE ELM327 interface, or one that does not even connect to the vehicle!

Save the hassle and stress! Our best pick ELM327 interface is the product you been looking for; it is the most affordable OBD2 ELM327 interface scanner out there that works well. I have personally used this scanner in my workshops and can say it’s the best ELM327 interface there in its price range. Guaranteed to work and be Genuine ELM327 interface

What is an ELM327 interface?

The ELM327 is a microprocessor programmed by Elmay, the company that produces it for translating our car’s OBD-II interface. This popular protocol has been implemented in many other devices as well! The ELM327 is a tiny computer that can be programmed to communicate with your car’s diagnostics port. It has become one of the most popular interfaces for converting between traditional diagnostic signals and newer OBD2 standards, which are found on cars made after 1998.

Difference between genuine vs fake ELM327 interface

genuine ELM327 interface

“Genuine,” “real version 1.5” ELM327 interfaces are based on the PIC18F25K80 chip produced by Microchip. In most cases, such interfaces are properly identified as “version 1.5” in online stores. You can use an Android app called ELM327 Identifier to analyze the device and verify it.

Fake ELM327 interface

When you’re looking for an interface, make sure it’s not “Fake.” Fake interfaces are built on cheap microcontrollers like the STM32F042 and YM1130. They usually come with a Chinese version 1 or 2 which can be impossible to use if your car doesn’t support those languages but many unfair sellers try selling these as V1 5 even though they aren’t really worth anything more than fake v1 4 commands that may not work!

In 2021, attention will shift to new types of fraudulent adapters produced in 2022 – which are built on a chip that has been relabeled as PIC18F25K80. Such relabelled chips have the following characteristics:

  • The fake chip (while the genuine chip has a clear and distinct logo) is blurred, making the Microchip logotype hard to identify.
  • On the counterfeit chip, the third line contains string 14309MP, 1643URE, or 1850AAJ; the real chip has additional strings with an encoded production date.

Pairing ELM327 Bluetooth Devices

Pairing ELM327 Bluetooth devices with smartphones, tablets, and PCs is typically a simple process. The following are the most frequent actions:

  1. Connect the ELM327 Bluetooth device to the OBD-II port.
  2. Set the device to search for available connections.
  3. Choose the ELM327 scan tool.
  4. Pair with the device by entering the pairing code.

ELM327 Bluetooth pairing code

Most of the time, an ELM327 Bluetooth scanner’s documentation includes a pairing code and distinct instructions beyond the basic outline. If no documentation is included, look for one of the following phrases:

  • 0000
  • 1234
  • 6789
  • 9999
