How to Transfer Calibrations from a Modified Tuning Firmware to the Downloaded Firmware from the Vehicle?

Transferring calibrations from a modified tuning firmware to the original firmware of your vehicle is a task that may arise when you want to retain tuner-made adjustments during a firmware update. In this article, we will explain how to perform the calibration transfer using a special utility designed for this purpose.

What Are Calibrations?

Calibrations are parameters that control the operation of various systems in your vehicle, such as fuel delivery, ignition timing, boost pressure, and many other aspects of the engine and transmission. In tuning firmware, these parameters are adjusted to improve performance, fuel efficiency, or vehicle dynamics.

When you update the firmware from your vehicle, the original parameters are replaced with factory settings. However, with the right tools, you can save your tuning adjustments, transfer them to the new firmware, and preserve the results you’ve achieved.

How to Transfer Calibrations?

1. Preparing Firmware Files

First, you will need two files:

• The original firmware — this is the firmware you downloaded from your vehicle.
• The tuning firmware — the modified firmware containing your adjusted calibrations.

Both firmware files should be in a format supported by your editing and flashing software.

2. Using the Special Utility

To transfer calibrations from one firmware to another, you need to use our calibration transfer utility. This tool automatically analyzes the differences between the two firmware files and allows you to select which parameters you want to transfer.

3. Steps to Follow

1. Load the firmware files. Open the utility and load the original firmware from your vehicle and the tuning firmware.
2. Analyze the differences. The utility will analyze the files and display the differences in calibrations. These can include changes to fuel maps, ignition timing, and other parameters.
3. Select parameters to transfer. Choose the calibrations you want to transfer from the tuning firmware to the original firmware. You can select all changes or only specific parameters.
4. Apply the changes. After selecting the necessary parameters, press the button to transfer the calibrations. The utility will create a new firmware that includes the parameters from the tuning firmware.
5. Write the firmware to the vehicle. Once you have the new firmware with the transferred calibrations, you can flash it to your vehicle’s ECU (Engine Control Unit) using appropriate software for flashing.

4. Advantages of Using the Utility

• Automatic analysis: The utility quickly and accurately identifies differences between the firmware files, saving time and reducing the risk of errors.
• Flexible parameter selection: You can choose which specific changes to transfer, avoiding unnecessary parameters.
• Ease of use: The utility is designed for user convenience, allowing complex operations to be performed in just a few steps.

Conclusion

Transferring calibrations from a tuning firmware to the original vehicle firmware is essential when updating firmware. With our utility, this process becomes quick and easy, allowing you to retain all the necessary adjustments to your vehicle.
