Different engines, different rules
A 320d, 330d, 340i or X5 can share a badge family while using very different control systems and limitations.

PREMIUM OVERVIEW
Why this remapping page is different
ECU and software identification matter
Support is confirmed by ECU family, software version, emissions equipment and overall vehicle condition.
Matched to the exact car
SGTM checks the exact BMW hardware before discussing a suitable Stage 1, Stage 2 or economy route.
ENGINEERING FIRST · SGTM
BMW performance tuning is engine- and ECU-specific
A BMW 320d, 330d, 340i or X5 can use very different hardware and calibration strategies even within the same model generation. ECU identification and software security are more useful than a badge alone when confirming available services.
We assess supported BMW diesel and petrol platforms, along with the condition of the cooling system, boost control, fuel system and automatic transmission where relevant. The available stage depends on the individual vehicle.

Important factors for BMW ECU Remapping
The correct service is based on ECU identification, mechanical condition and the proposed road-compliant calibration.
Torque and driveability
N47, B47, N57 and other diesel-family enquiries require engine and ECU identification, not assumptions.
Turbocharged applications
Selected turbocharged BMW petrol platforms may support a vehicle-specific Stage 1 or hardware-led Stage 2 review.
TCU/EGS coordination
Certain BMW automatic transmissions may need separate gearbox programming or torque-limit considerations.

BMW ECU Remapping FAQs
Can you remap my BMW 320d?
Many BMW diesel families have tuning options, but the year, exact engine, ECU and software security determine what SGTM can offer.
Is BMW gearbox tuning included?
No. TCU/EGS tuning or programming is a separate assessment and quotation where supported.
Do you support BMW Stage 2?
Selected suitably modified BMW engines may be assessed for Stage 2. We must review hardware and ECU support first.
What do I send before booking?
Registration, VIN, engine code, year, modifications and any warning lights or existing tuning information.
