Fiat Marea 1997-2002 2.4 JTD HLX 130bhp Stage 1 Eco remap figures
The Stage 1 Eco map for the Fiat Marea 2.4 JTD HLX 130bhp (1997-2002): 168bhp and 379Nm expected from a standard 130bhp and 304Nm, up to +38bhp and +75Nm. It keeps most of the Stage 1 gain (Stage 1 is 180bhp and 385Nm) 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 Fiat Marea is expected to give 180bhp and 385Nm (+50bhp, +81Nm). The Stage 1 Eco keeps about 76% of that power gain and 93% of the torque gain, so you get 168bhp and 379Nm: 12bhp 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 130bhp and 304Nm.
What this means for your Marea
On a diesel the biggest change is normally torque: the remap changes how much fuel and boost the ECU allows across the rev range, so pulling power arrives earlier and holds on longer.
Engine management is by a Bosch EDC15C5 unit. 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 Fiat Marea 2.4 JTD HLX 130bhp?
We expect 168bhp and 379Nm against 130bhp and 304Nm as standard: up to +38bhp and +75Nm. 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 180bhp and 385Nm. Stage 1 Eco gives 12bhp 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 (168bhp and 379Nm) and still care about running costs. Choose the Eco map (164bhp and 374Nm) 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.
