Frequently asked questions
Do all Mercedes-Benz CLA 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 Mercedes-Benz CLA generations?
Not meaningfully — most Mercedes-Benz CLA files across generations are handled within a few hours of upload, regardless of which ECU the generation uses.
Is my Mercedes-Benz CLA 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 Mercedes-Benz CLA 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.
