Renault Laguna (III) 2010-2012 2.0 DCi 128bhp Stage 1 Eco remap figures

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 Renault Laguna is expected to give 200bhp and 433Nm (+72bhp, +113Nm). The Stage 1 Eco keeps about 75% of that power gain and 92% of the torque gain, so you get 182bhp and 424Nm: 18bhp less and 9Nm 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 128bhp and 320Nm.

What this means for your Laguna

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.

This car is listed with a Bosch EDC17CP58 engine control unit. We read the ECU on your car and compare it with the software listed here before any work starts, so you know what to expect before you commit.

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.
