Stage 1 remap figures

A Stage 1 remap is a software-only change to the ECU on an otherwise standard car. It needs no extra parts, which makes it the usual starting point.

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 Megane

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.

Engine management is by a Bosch EDC17CP19 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.

Stage 1 questions

How much power does the Stage 1 map give the Renault Megane 2.0 DCi 172bhp?

We expect 226bhp and 447Nm against 172bhp and 359Nm as standard: up to +54bhp and +88Nm. These are expected figures, and we confirm what is achievable on your own car after a diagnostic check.

Does a Stage 1 remap need any extra parts on the Renault Megane 2.0 DCi 172bhp?

No. Stage 1 is a software-only change to the ECU on an otherwise standard car.

Is there a gentler map than Stage 1 for this engine?

Yes, two. Stage 1 Eco is performance with economy in mind: 213bhp and 440Nm expected. The Eco map is economy first: 208bhp and 436Nm. Both still sit above the standard 172bhp and 359Nm.

Do I need to tell my insurer about a remap?

Yes. A remap is a modification, so you should declare it to your insurer.
