An OBD2 engine ECU diagnostics tool that utilizes a Wi-Fi/Bluetooth ELM327 adapter offers comprehensive vehicle diagnostics, allowing you to tap into the electronic control units (ECUs) of your car. This powerful tool not only displays real-time data from various vehicle systems but also lets you save and review this data later. It's perfect for diagnosing and resetting engine fault codes, also known as DTC trouble codes, ensuring your vehicle runs smoothly.

One of the standout features is the ability to set custom min/max values for each sensor/PID. This means you can configure an "alarm" to trigger when readings fall outside these thresholds, helping you stay on top of your vehicle's health. The tool supports both Bluetooth and Wi-Fi ELM327 OBD adapters, but for optimal performance, we recommend using adapters version 1.5, as version 2.1 has received numerous complaints about incorrect functionality.

Important Note: The ELM327 chips are compatible only with vehicles that support OBD2, which includes:

• Cars manufactured in the USA since 1996
• In European countries since 2001 for gasoline cars and 2003 for diesel cars
• In Japan since around 2000

In addition to standard OBDII parameters, this diagnostics tool supports special parameters for various car brands, including but not limited to:

• ZAZ - (MIKAS10.3/11.3, MR140)
• UAZ - (MIKAS10.3/11.3, MIKAS11/E2, M86CAN)

Please note that not all PIDs listed for a specific car brand may be supported by your vehicle. You can select the types of PIDs you need in the "Settings / PID types" section for convenience.

For certain car brands, such as some Mitsubishi models, you can control various systems like turning on the cooling fan or fuel pump. To read MUT parameters and control actuators on Mitsubishi models with a CAN bus (e.g., Montero/Pajero IV, Outlander 2), you need to create a profile with the ISO 9141-2 protocol. For reading CAN parameters, use the ISO 15765-4 CAN (11bit 500K) protocol or set it to automatic. Keep in mind that not all Mitsubishi CAN-bus models support ISO 9141-2 connectivity.

The tool also offers ample opportunities for creating your own custom parameters, enhancing its versatility.
