Request a vehicle-specific Stage 1, Stage 2, Stage 3, economy or TCU calibration using the untouched original ECU/TCU read, exact software and hardware identifiers, vehicle information and reading-tool details. Our online file service supports equipped enthusiasts, independent tuners and professional workshops in the UK and supported international markets. Reading and writing require compatible equipment and competent handling; the customer portal accepts the file and enquiry without a workshop visit.
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.
Standard and remapped power. Torque across the rev range.

Original or near-standard vehicles
Stage 1 ECU calibration is considered for a compatible engine and original hardware. DPF and EGR deletion/removal requests are assessed separately and only for independently verified lawful non-road use.
Software-file request only. No physical DPF or EGR removal is included.
Request a combined file quotationModified engine and supporting hardware
Stage 2 ECU calibration is designed around declared and verified hardware changes. Any requested DPF or EGR software changes require ECU identification, a technical review and confirmation of lawful non-road use.
Software-file request only. No physical DPF or EGR removal is included.
Request a combined file quotationBespoke competition and advanced builds
Stage 3 ECU calibration requires an individual engineering assessment of the vehicle, supporting hardware and intended use. DPF and EGR requests are considered only where legal and technically suitable.
Software-file request only. No physical DPF or EGR removal is included.
Request a combined file quotationDPF delete/removal and EGR delete/removal are not road-legal options for UK public-road vehicles where the modifications defeat required emissions controls. Combined file requests are accepted only for genuinely lawful, verified non-road applications and are subject to the law in the vehicle's destination and place of use. SGTM does not supply these bundles to bypass emissions requirements on road vehicles. Ordinary road vehicles can be assessed for emissions-compliant Stage 1–3 tuning and appropriate DPF/EGR diagnosis or repair.
Online file requests can combine compatible tuning and software options after the original file and diagnostic context have been reviewed. Mechanical, electrical and safety faults must be repaired; a modified file is not a substitute for vehicle diagnosis.
Vehicle-specific torque request and limiter calibration, coordinated with the engine and transmission limits.
DPF-related file work is offered only for lawful off-road, motorsport, export or other permitted applications.
Targeted EGR calibration after the correct ECU file, fault context and intended legal use are confirmed.
