Prices at a glance
Three distinct options: BMW ECU unlock only, the complete BMW package or a standard Stage 1. Your vehicle and ECU details determine which option is suitable.
BMW ECU unlock without Stage 1
Standard: €150 per approved ECU, including removal and refitting; following the preliminary check, the work is completed on the same working day. S68 is excluded: €500 per ECU or €899 for both; turnaround is confirmed separately. Stage 1, a map and an app licence are not included.
BMW ECU unlock in detailBMW same-day package
A clearly defined scope for BMW vehicles with B47, B48, B57, B58 or S58 engines — including locked ECUs from around 07/2020. Vehicle identification determines whether the package is suitable.
BMW package in detailStage 1
The starting price applies to technically suitable vehicles with straightforward ECU access. The ECU, access method, vehicle condition and diagnostic work determine the final price, which is confirmed before work begins.
Stage 1 in detailOur range of services
MG AutoTech’s work extends beyond near-standard Stage 1 tuning. Alongside everyday optimisations, we support performance models, supercars and individually built high-performance projects. Decisions are based on hardware, software version, fuel, thermal headroom, transmission limits and intended use — not blanket power promises.
ECU and TCU software, diagnostics, unlocking, data analysis and vehicle-specific calibration work together — for standard cars, performance models and supercars alike.
Vehicle-specific software tuning for near-standard petrol and diesel cars. The focus is usable torque, responsiveness and a result suited to everyday driving.
Stage 1 & software optimisation02AMG · M · RS · PorschePerformance calibration for powerful production platforms and existing hardware upgrades. ECU and TCU are considered together, not in isolation.
Performance Engineering03SupercarsTechnical project assessment and software solutions for Ferrari, Lamborghini, McLaren, Aston Martin, Bentley and other exotic cars. Control unit, software version and vehicle condition are checked before any commitment.

Most enquiries begin with a warning light, a dashboard message or a car that will not start. Choose what matches your situation and we will help identify the right area.
An engine warning light, dashboard message or fault code from a diagnostic tool.

Our approach
Vehicle software, diagnostics and control-unit services depend on the vehicle in question. That is why the process starts with data, symptoms and a technical assessment.
Make, model, year of manufacture, engine and the issue or objective are recorded in a structured way.
MG AutoTech assesses whether diagnostics, software, coding or control-unit work is appropriate.
Only then is the right route agreed: an on-site appointment, further contact, shipping or the B2B platform.
Your starting point
Send your vehicle details and a description of the issue. MG AutoTech will then establish the appropriate technical route for your enquiry.
