Welcome to the Iron Loader V2 Installation Guide! Built to unlock improved vehicle‑level performance, this tool lets you load custom tunes conveniently via your smartphone or tablet. The Iron Loader V2 connects wirelessly to your vehicle over Bluetooth and works alongside the PowerGate app, delivering a smooth, hassle‑free tuning experience. Follow the step‑by‑step instructions below to get started!
Step 1: Preparing Your Device
Before you get started, please confirm you have all of the following items ready:
- A smartphone or tablet running iOS or Android.
- A stable Wi‑Fi connection to upload and download your tune file.
- The PowerGate app installed on your mobile device. You may download it from the
App Store or Google Play using the links provided below:
Step 2: Connecting the Iron Loader V2 to Your Vehicle
- Plug the OBD2 cable into the Iron Loader V2 module (insert the serial‑end of the cable into the female serial port on the unit).
- Connect the OBD2 connector on the cable to your vehicle’s OBD2 port.
- Enable Location Services and Bluetooth on your iOS or Android device to establish communication with the Iron Loader.
- Allow the unit to power up; you will know it is ready once the LED indicator illuminates and turns BLUE.
- After the device has booted up, launch the “PowerGate” app on your smartphone.
- Complete the Bluetooth pairing between your phone and the Iron Loader through the application; you may need to open your phone’s Bluetooth settings to finish this connection.
- You will also need an active Wi‑Fi connection during this workflow to successfully tune your vehicle.
- Once the Bluetooth and Wi‑Fi connections are active, the device will begin an automatic software and firmware update. Do not disconnect power until this update finishes.
Step 3: Reading Stock File
- Keep your phone connected to the Iron Loader V2 over both Bluetooth and Wi‑Fi.
Launch the PowerGate application. - Follow the on‑app prompts to start reading the original stock file from your vehicle’s ECU.
- Set your vehicle’s ignition to the “ON” position (engine off) for the entire reading process.
- Make sure virtual reading is selected during the ECU‑communication phase.
- Allow several minutes for the app to finish the read‑out process.
- When reading completes, the app will prompt you to save the stock file. Save the file locally to your phone by following the screen instructions.
Step 4: Uploading and Downloading the Custom Tune
You are now ready to submit your stock file and retrieve your finished custom tune:
- Right after saving your stock file, the PowerGate app will automatically prompt you to upload it to our tuning server.
- Maintain a reliable internet connection while the file uploads.
- Once the upload succeeds, you will receive an in‑app notification when your custom tune is available.
- Download the completed custom tune file to your phone through the PowerGate app.
Your custom tune file is now ready to flash onto your vehicle!
Step 5: Writing the New Tune to Your Vehicle
- Use these steps to flash your new custom tune to the vehicle ECU:
- Reconnect the OBD2 cable between the Iron Loader V2 and your vehicle’s OBD2 port, exactly as you did in Step 2.
- Confirm the device powers on and its LED light shows blue.
- Open the PowerGate app and verify the unit remains connected over Bluetooth and Wi‑Fi.
- The app may ask you to redo Step 2: Connecting the Iron Loader V2 to Your Vehicle. If prompted, revisit the connection instructions above.
- Tap the write button inside the application.
- Select the custom tune file you previously downloaded from the app file list.
- Follow the on‑screen prompts to write your new tune to the vehicle ECU. Keep the ignition switched to “ON” (engine off) throughout the flashing procedure.
- Do not cut power or close the app mid‑process. Wait for a success confirmation from the device.
- Once flashing is finished, turn off your vehicle ignition and unplug the OBD2 cable.
