Renault Megane (III) 2013> 1.2 16v TCE 128bhp Stage 1 Eco remap figures

Who is the Stage 1 Eco map for?

• Drivers who want a quicker, more responsive car, tuned with economy in mind.
• Daily drivers who want strong mid-range pull without giving up efficiency.
• 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 Megane is expected to give 155bhp and 236Nm (+27bhp, +31Nm). The Stage 1 Eco keeps about 74% of that power gain and 94% of the torque gain, so you get 148bhp and 234Nm: 7bhp less and 2Nm 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 205Nm.

What this means for your Megane

On a turbocharged petrol engine a remap adjusts boost, ignition timing and fuelling together, so both power and mid-range torque rise and the car pulls harder out of corners and junctions.

Engine management is by a Siemens EMS3150 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.
