Step 1: Choose an End User Tuning Device

To get started, you need one of the dedicated personal ECU flashers designed specifically for end users. These devices are actually connected to your car's diagnostic port, also known as OBD2, and allow you to reprogram the Engine Control Unit (ECU or EMS) through them.

Step 2: Read Your ECU at Home

Once you receive the device:
