Nissan Teana ECU remapping
6 files available
About remapping
The Nissan Teana accounts for 6 files in our catalogue, entirely naturally aspirated petrol: the 2.5i V6 leads, with 2.0i and 2.3i units also present. It is a mid-size saloon sold primarily in Asian markets.
Stage 1 accounts for all 6 files — a completely clean profile with no maintenance work at all. The ECU is a single reference across the whole catalogue: SH72531. Being naturally aspirated, the gains here are modest by nature.

How much does a naturally aspirated engine gain?
Considerably less than a turbocharged one — there is no boost to adjust. We are honest about this: expect refinement in delivery, not a large power figure.
Does it affect the CVT gearbox?
The work is done on the engine ECU. On CVT vehicles we work with particular care to keep delivery within what the transmission handles well.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
