Lexus UX Generations
Engine options and ECU hardware change between Lexus UX generations, which is why the catalogue splits here. Choose the one that matches your car.
The 1 Lexus UX generations below each open onto their own engine list. Chassis code or build year from the registration document is usually enough to tell them apart if you're not certain.
Frequently asked questions
Do all Lexus UX 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 Lexus UX generations?
Not meaningfully — most Lexus UX files across generations are handled within a few hours of upload, regardless of which ECU the generation uses.
Is my Lexus UX 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 Lexus UX 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.
