Nissan Primera (P12) 2002-2008 2.2 Di 124bhp Stage 1 Eco remap figures
The Stage 1 Eco map for the Nissan Primera 2.2 Di 124bhp (2002-2008): 155bhp and 345Nm expected from a standard 124bhp and 279Nm, up to +31bhp and +66Nm. It keeps most of the Stage 1 gain (Stage 1 is 165bhp and 351Nm) and is tuned with economy in mind: the choice if you want the performance and care what each tank costs.

Stage 1 Eco remap figures
Stage 1 Eco is performance with economy in mind. It keeps most of the Stage 1 gain, so the car still pulls well, but the map is shaped for efficient, relaxed driving rather than flat-out output. It is above the standard figures. We don't quote mpg, because economy depends on the car and how it is driven.

Who is the Stage 1 Eco map for?
- Drivers who want the pull of a remap for overtaking, motorways and towing, with the engine tuned with economy in mind.
- High-mileage drivers who want better performance and a more efficient everyday car in one map.
- Anyone who would otherwise take full Stage 1 but cares what each tank costs.
How Stage 1 Eco compares with Stage 1
Full Stage 1 on this Nissan Primera is expected to give 165bhp and 351Nm (+41bhp, +72Nm). The Stage 1 Eco keeps about 76% of that power gain and 92% of the torque gain, so you get 155bhp and 345Nm: 10bhp less and 6Nm less than Stage 1, with the map shaped for efficient, relaxed driving, so it suits you if you want the pull and care about running costs. Both sit above the standard 124bhp and 279Nm.
What this means for your Primera
Diesel remaps work mainly on boost pressure, fuel delivery and torque limiters, which is why the Nm gain is usually the figure you feel in everyday driving, particularly when overtaking or towing.
The ECU recorded for this variant is a Denso. Older engine management is simpler to work with, but age matters: worn sensors, leaks and tired components can hold back what a remap delivers, which is why we run a diagnostic check first.
We remap at our Belgrave Gate workshop in Leicester, or at your home or work within 30 miles, and every job starts with a diagnostic check.
Please note: these are expected figures, not guarantees. Real results vary with the condition of the vehicle, the ECU software version, fuel quality and the hardware fitted. Some options - including Stage 2 and anything that needs extra hardware - are for off-road or competition use only. We check every vehicle first and confirm what is achievable before any work starts.

How much power does the Stage 1 Eco map give the Nissan Primera 2.2 Di 124bhp?
We expect 155bhp and 345Nm against 124bhp and 279Nm as standard: up to +31bhp and +66Nm. These are expected figures, and we confirm what is achievable on your own car after a diagnostic check.
How does Stage 1 Eco differ from Stage 1 on this engine?
Full Stage 1 is expected to give 165bhp and 351Nm. Stage 1 Eco gives 10bhp less and 6Nm less, in exchange for a map shaped with economy in mind. It still sits above the standard figures.
Is Stage 1 Eco or the Eco map better for me?
Choose Stage 1 Eco if you want the performance (155bhp and 345Nm) and still care about running costs. Choose the Eco map (151bhp and 342Nm) if economy matters more than pace.
Will the Stage 1 Eco map save fuel?
It is tuned with economy in mind while keeping most of the Stage 1 performance. We do not quote mpg figures, because economy depends on the car, its condition and how it is driven.
Do I need to tell my insurer about a remap?
Yes. A remap is a modification, so you should declare it to your insurer.
