If you’ve purchased a Dynojet Power Vision 3 (PV3) and plan to use a current Fuel Moto or Dynojet tune (.djt), it’s essential to update the tune file correctly. Otherwise, you may encounter error code 419, preventing you from flashing your tune. This process requires a Windows computer. Follow these straightforward steps to ensure your tune file is properly updated before sending it to your PV3 device.
Step 1: Download the Dynojet Power Core Software
First, ensure you have Dynojet Power Core software (version 1.12.5 or later) installed on your Windows computer. You can download it directly from the Dynojet website. This software is necessary for the update process.
Step 2: Save Your Tune Files
Next, save your .djt tune file to a convenient location on your computer, such as your desktop. This file may have been downloaded from www.dynojetpowervision.com or emailed to you by Fuel Moto.
Step 3: Open the Tune File in Power Core
Launch the Power Core software suite and select C3 Tuning Software from the available options.
In the upper left corner, click on “Open” and browse to the location where your .djt tune file is saved.
Select the tune file, and C3 Tuning Software will automatically install the appropriate tune definitions and update the tune file.
After the update, click “Save” to ensure the tune file is properly updated.
Step 4: Transfer the Updated Tune to Your PV3 Device
With your tune file now updated, it’s time to transfer it to your PV3 device:
Close the Power Core software.
Connect your PV3 device to your computer using a USB cable.
Right-click on the updated .djt tune file and select “Send Tune > Dynojet Power Vision.”
Alternatively, you can drag and drop the .djt tune file directly onto the PV3 device.
Step 5: Flash the Tune to Your ECU
With your updated tune file successfully transferred, you’re ready to flash your tune to your ECU. Follow your PV3 device’s on-screen instructions to complete the process.
It’s crucial to also save a copy of your original ECU read .stk file in the same location. This step ensures you can easily access both files during the update process.
By carefully following these steps, you’ll avoid the common error code 419 and ensure your Dynojet Power Vision 3 device can seamlessly communicate with your Harley-Davidson. This process keeps your tune files current, ensuring the best performance for your bike. Now, you’re ready to hit the road with confidence, knowing your tune is perfectly dialed in!
