ELM327 Mini is capable of reading CEL codes and tells you where and what the problem is. However, the scanner’s code is complicated for a beginner to understand as it contains letters and digits.

Freeze Frame Data: This feature helps to keep the emission system of a vehicle in good shape. It’s a screenshot that contains useful PID information for the shown DTC codes.

In other words, it saves the codes in the memory when a problem in the emission system occurs so that you can view a detailed side-by-side report on various codes.

You can also share this information with professionals for their inputs.

Live Data: With this feature, you will be able to determine how the vehicle performs as you drive. It gives a live data feed of your car using built-in sensors.

  • Ignition Response: It will tell you about the time taken to ignite the fuel mixture. A long delay indicates that the car has ignition problems.
  • Speed: Problems in the emission system can be picked by looking at the speed of the vehicle. If your car is running slower than usual, there could be a problem with the emission system. You can pull up live data on the speed sensor and see your car’s running speed.
  • Revolution Per Minute: This information can help you gauge the overall condition of your vehicle.
  • Throttle Position: It shows data related to the engine air intake.

Mass Air Flow: There’s a sensor inside the engine that reads the airflow that enters into the combustion engine. You can see this data live using ELM327 Mini.
