Real engineers.
Engine calibration, software development and vehicle technology grounded in practical experience.
QNTUM21 · Engineered in Germany
Your vehicle.
Your decision.
We develop technology that allows people to retain control over their own vehicle – independently, transparently and through genuine engineering.
Experience became a mission
We did not found QNTUM21 to repackage existing software.
We founded QNTUM21 because vehicle owners should be more than users of closed systems. They should be able to understand, decide and remain in control. At a time of growing dependencies, technology should return that control to its owner.
Our first major step
Q21 Flasher.
A newly conceived software platform for BMW Group vehicles. Q21 Flasher combines calibration, diagnostics, software updates and data analysis in one application.
Not a file service. Not anonymous software. Vehicle-specific, technically traceable and developed by people who understand the engine, transmission, electronics and software as one system.

Real technology.
Measurement data, protection functions and vehicle architecture instead of generic software files.
Your control.
Tools that let people determine the possibilities of their own vehicle.
