Professional ECU file solutions across 145+ ECU and TCM models — VAG (VW, Audi, Škoda, SEAT), BMW / MINI, China cars, GM, Ford and KIA / Hyundai — plus JLR MDG1, Ford SID208 and Porsche BCM services. Bosch, Delphi, Magneti Marelli, Siemens / Simos, MD1 / MG1, ME / MEV and transmission control units. Send us your ECU file or unit and we process it professionally with full checksum correction.
All solutions are file-based — read your ECU, send us the file on WhatsApp, and receive a clean, checksum-corrected file ready to flash back.
Immobiliser removal
We disable the immobiliser in the ECU/TCM so the unit will start and run without the original key, IMMO box or BCM handshake — ideal for engine swaps, replacement ECUs, cloning and repair work.
Diesel particulate filter
Software removal of the Diesel Particulate Filter function — disables regeneration, soot/ash counters and related DTCs after a filter is gutted or replaced with a straight pipe. Restores driveability and prevents limp mode.
Exhaust gas recirculation
Disables the Exhaust Gas Recirculation valve in software so it no longer recirculates hot exhaust gases — reduces intake carbon build-up, improves throttle response and eliminates EGR fault codes.
SCR / DEF system
Deactivates the SCR / AdBlue (DEF) system in the ECU — removes NOx monitoring, urea dosing and the AdBlue countdown/no-start strategy. A clean solution when the SCR system or NOx sensors fail.
Note: DPF, EGR and AdBlue removal are intended for off-road, motorsport and export vehicles. Please ensure compliance with the emissions regulations in your country before requesting a solution.
145 ECU / TCM models and protocols supported for IMMO / DPF / EGR / AdBlue solutions, by vehicle group.
Total immobilizer delete via Flash/EEPROM modification. Perfect for E36, E46 and E39 engine swaps (M52, M52TU, M54) or custom track builds where the original EWS module is removed.
Pure software-based IMMO OFF file patch. Completely bypasses the EWS/CAS hardware handshake in the code so the ECU never immobilises itself again — no physical emulator hardware required.
IMMO OFF for the Tricore generation of BMW / MINI engine control units and related modules.
Professional immobiliser removal and checksum correction for the Continental SID208 engine control unit used across Ford Ranger and Transit platforms. File-based service — send us your ECU read and receive a clean IMMO OFF file with correct checksums, ready to flash.
Solution for Bosch MDG1 ECUs in post-2020 Jaguar Land Rover vehicles — Defender, Discovery, Discovery Sport, Range Rover, Range Rover Sport, Velar and F-Pace.
Compatible ECUs
Complete immobilizer data recovery, synchronization and cloning for Porsche Body Control Modules — including Cayenne, Panamera and Macan. Expert processing for both Continental and Delphi BCM architectures.
Our IMMO OFF tooling is updated continuously with new ECU and TCU coverage — including many world-first and exclusive releases.
