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 a sharper throttle and a small, honest gain from software alone.
  • Owners who would rather keep the car standard in every other way.
  • Anyone who wants the fullest software-only map for this engine, accepting that the gain is modest without a turbocharger.

What this means for your X7

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.

This car is listed with a Bosch MG1CS201 engine control unit. 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.

Stage 1 questions

How much power does the Stage 1 map give the BMW X7 40i MH 375bhp?

We expect 455bhp and 615Nm against 375bhp and 540Nm as standard: up to +80bhp and +75Nm. 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 BMW X7 40i MH 375bhp?

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: 435bhp and 609Nm expected. The Eco map is economy first: 429bhp and 605Nm. Both still sit above the standard 375bhp and 540Nm.

Do I need to tell my insurer about a remap?

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