Key Features & Functions
- Reset Working Hours: Allows you to reset the internal operating time (working hours) of the DME. This is often a necessary step when adapting a used DME to a new vehicle to ensure proper function.
- Change Power Class: Easily change the Power Class of the DME to match your vehicle's engine variant. This is a critical function for engine swaps or performance upgrades (e.g., converting a 523i to a 530i).
- Code Decat Variant: Apply a "decat" patch directly to the firmware. This is used to prevent Check Engine Light errors related to the catalytic converter after installing a catless downpipe or performance exhaust system.
- File Validation & Checksum Correction: The software automatically validates the loaded file size to ensure you are working with a correct MSV80 dump and handles checksum corrections after patches are applied.
How to Use
The workflow is designed for simplicity:
- Open your full flash file read from the MSV80 DME.
- The software will analyze the file and show its status.
- Apply the desired function (Reset Hours, Change Power Class, etc. - functions applied automatically or via context menu depending on version).
- Save the patched file and write it back to your DME.
