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?
- Naturally aspirated owners who want a little more response and a more efficient, relaxed drive. Every map we list stays above standard.
- Drivers who want the small gain on offer without chasing peak output.
- Anyone who would otherwise take the full Stage 1 map but wants it tuned with economy in mind.
How Stage 1 Eco compares with Stage 1
Full Stage 1 on this BMW 2 Series is expected to give 436bhp and 622Nm (+101bhp, +122Nm). The Stage 1 Eco keeps about 75% of that power gain and 92% of the torque gain, so you get 411bhp and 612Nm: 25bhp less and 10Nm 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 335bhp and 500Nm.
What this means for your 2 Series
Naturally aspirated petrol engines have no boost to raise, so gains from software alone are more modest than on a turbocharged car and come from fuelling, ignition and throttle response.
The ECU recorded for this variant is a Bosch MG1CS003. Newer ECUs often protect their software, so we read the exact unit and version on the car before confirming the figures on this page.
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.

Do I need to tell my insurer about a remap?
Yes. A remap is a modification, so you should declare it to your insurer.
