Who is the Stage 1 map for?

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 Zafira Tourer

On a diesel the biggest change is normally torque: the remap changes how much fuel and boost the ECU allows across the rev range, so pulling power arrives earlier and holds on longer.

The ECU recorded for this variant is a Bosch EDC17C59. 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.
