Send your untouched original ECU read with the complete vehicle, ECU, tool and hardware details. SG-Tronic Motorsport can assess Stage 1, Stage 2, Stage 3, torque-limiter, TCU and supported specialist software requests for professional workshops, mobile tuners and equipped trade customers.
Every calibration request starts with the original ECU read, vehicle specification, fuel type, transmission and hardware modifications. The correct stage is determined by the mechanical setup—not simply by selecting the highest number.
A vehicle-specific performance calibration for a mechanically standard or near-standard vehicle. Depending on the application, the file may optimise boost control, fuelling, ignition, throttle response and factory torque limiters while respecting sensible operating limits.
Stage 2 tuning is developed around compatible supporting hardware such as intake, intercooler, exhaust or turbo-related upgrades. The exact specification must be supplied so the calibration matches the physical vehicle.
A specialist calibration for substantially modified, motorsport-focused vehicles with upgraded turbocharger, injectors, fuel system, engine hardware or transmission. Detailed logs and controlled testing may be required.
Upload an untouched original ECU read to request a custom economy tuning file for a supported car, van, pickup, motorhome or light-commercial vehicle. The calibration is matched to the vehicle, engine, ECU software, transmission, declared hardware and intended everyday use.
This online economy remap file service is suitable for professional workshops, equipped mobile tuners and trade customers who can read and write the ECU safely. Supply the exact ECU identification, reading tool and method, vehicle details, diagnostic codes and any modifications.
Before ordering: economy and MPG results depend on vehicle condition, load, route and driving style. A tuning file is not a repair for mechanical, electrical, sensor or emissions faults. Previously tuned files do not include checksum correction.
Vehicle-specific eco map development based on the original ECU file rather than a generic calibration.
Economy ECU files for supported diesel vans and working vehicles, with usable low-RPM torque and drivability in focus.
Supported torque and throttle strategies are calibrated for progressive delivery and efficient normal-road operation.
The software version, ECU family, read method and vehicle specification are reviewed before the request is accepted.
