Infiniti FX Generations
Engine options and ECU hardware change between Infiniti FX generations, which is why the catalogue splits here. Choose the one that matches your car.
The Infiniti FX range breaks down into 1 generations in our system, each one a separate branch with its own engines and, eventually, its own dyno-tested performance figures.
Frequently asked questions
Do all Infiniti FX 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 Infiniti FX generations?
Not meaningfully — most Infiniti FX files across generations are handled within a few hours of upload, regardless of which ECU the generation uses.
Is my Infiniti FX 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 Infiniti FX 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.
