QLaunchr is a lightweight Windows utility for offline editing of launch-related RPM parameters inside supported ECU calibration files.
It provides a simple workflow to load a file, select vehicle make and ECU type, enter a launch RPM setpoint, and adjust an RPM cut speed value, then save an output file for controlled evaluation.


Highlights

• Offline file workflow with Load File and Save File actions
• Vehicle make and ECU selectors to match supported profiles
• Launch RPM setpoint input field for quick parameter entry
• RPM cut speed adjustment control with faster and slower guidance
• Summary panel to review the prepared output information
• Built-in warning about checksum correctness and the risks of incorrect file writing

Compatibility notes
This is an offline file utility and it does not diagnose a vehicle by itself.
Results depend on the ECU family, file type, and how the file was read.
Use only professional writing tools that support correct checksum handling.
