In this guide, we’ll walk you through the steps from Dynojet’s latest instructional video on how to use PV4 AutoTune with Dynojet App.

What is AutoTune & Why Use It?

AutoTune is a feature within the Power Vision PV4 that helps adjust and refine your bike’s fuel map in real-time. Whether you’ve installed a new exhaust, intake, or camshaft, AutoTune allows your EFI system to make necessary adjustments based on live sensor data, improving throttle response, fuel efficiency, and overall performance.

Step-by-Step Guide to Using PV4 AutoTune with Dynojet App

1. Connect Your PV4 to the Mobile App

• Ensure your Power Vision PV4 is connected to your bike’s diagnostic port.
• Open the Dynojet Mobile App on your smartphone or tablet.
• Use Bluetooth pairing to link the PV4 with the app.

2. Start AutoTune Mode

• In the app, navigate to the AutoTune feature.
• Select your current fuel map or load a new one if needed.
• Tap Start AutoTune—this activates the feature and allows it to begin gathering real-time riding data.

3. Ride & Gather Data

• AutoTune works best when riding through a variety of throttle positions and RPM ranges.
• Take the bike for a short ride, allowing the PV4 to collect data and make fuel adjustments as you ride.
• You’ll see real-time adjustments on the app, helping to fine-tune your fuel map.

4. Save & Flash the Adjusted Map

• Once you’ve gathered enough data, return to the app and review the suggested changes.
• If satisfied, tap Apply & Flash to upload the optimized fuel map to your ECM.
• Restart your bike and let it idle to ensure the new map is properly loaded.

Pro Tips for Best Results

Start with a base map – Using a Dynojet preloaded map close to your setup will improve AutoTune accuracy.
Ride in different conditions – Try highway cruising, stop-and-go traffic, and aggressive acceleration to gather a full range of data.
Check your modifications – AutoTune works best when paired with a well-matched exhaust and intake system.
