EA888 Gen3 Tuning

Flash a Stage 1 tune to your EA888 Gen3 directly from the simos.app. Connect the dongle, open the app, and you're tuned in minutes.

How It Works

1. Plug In

Connect the simos.app dongle to your car's OBD-II port. Turn the ignition on but don't start the engine.

2. Connect

Open the simos.app on your phone. The app connects to the dongle over Bluetooth automatically.

3. Purchase

Go to the Tune tab in the app and purchase Stage 1 for your VIN. The tune is built specifically for your ECU calibration.

4. Flash

Tap Flash and let the dongle write the tune to your ECU over OBD. The process takes a few minutes — don't disconnect until it's done.

That's it. Start the engine and enjoy the extra power.
