Steyr 4120 Generations
Engine options and ECU hardware change between Steyr 4120 generations, which is why the catalogue splits here. Choose the one that matches your car.
We split the Steyr 4120 into 1 generations because engine options — and the tuning ceiling that comes with them — genuinely change across the model's production run.
Frequently asked questions
Do all Steyr 4120 generations support the same tuning stages?
No — available stages depend on the specific engine in that generation, not the model as a whole. Once you pick your engine, its performance page shows exactly which stages apply.
Does turnaround time differ between Steyr 4120 generations?
Not meaningfully — most Steyr 4120 files across generations are handled within a few hours of upload, regardless of which ECU the generation uses.
Is my Steyr 4120 generation supported for safe remapping?
If it's listed in our catalogue, yes — every engine in every generation shown here has been worked before, with stage limits set to stay within that engine's mechanical margins.
How do I know which Steyr 4120 generation I have?
Check your vehicle registration document for the build year, or look up the chassis code — both narrow it down to one of the generations listed here.
