Renault Laguna (II) 2001-2007 1.9 DCi 93bhp remap figures

Who is the Stage 1 map for?

• Drivers who want stronger pulling power for overtaking, hills and towing, with no parts to fit.
• Daily and motorway drivers who want the engine to feel less strained at cruising speed.
• Anyone who wants the biggest software-only change we list for this engine.

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.

The ECU recorded for this variant is a Bosch EDC16C0/C3. 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.
