Engine management, transmission control, and all-wheel drive modules for Jaguar and Land Rover. ECU, TCU, PTU, and chassis control units with flash programming support.
The powertrain control modules are the brain of your Jaguar or Land Rover's engine, transmission, and drivetrain. We supply, program, and support the full range of JLR powertrain modules.
The primary engine management module controlling fuel injection, ignition timing, emissions, and throttle response. JLR ECUs are programmed to specific engine variants and emission standards. We offer ECU replacement, cloning, and flash programming for petrol, diesel, and hybrid powertrains.
Manages automatic and dual-clutch transmission operation, shift points, torque converter lockup, and adaptive learning. A failed TCU can cause harsh shifting, limp mode, or complete transmission failure. We provide tested TCUs with pre-loaded transmission calibration.
The all-wheel-drive control module that manages torque distribution between front and rear axles. Common in Range Rover and Discovery models. PTU failures often manifest as AWD warning lights and reduced traction. We supply replacement PTU modules and control units.
Comprehensive engine control solutions for all JLR petrol, diesel, and hybrid engines.
When an ECU is damaged beyond repair, we can supply a replacement and clone the original configuration data to the new unit. This preserves immobilizer matching, VIN data, and calibration parameters. Compatible with Bosch, Continental, and Magneti Marelli ECUs used in JLR vehicles.
Update or downgrade engine calibration files using genuine JLR DOIP VCI and official software. Flash programming is required after ECU replacement, for emissions updates, and when retrofitting performance upgrades. We support all JLR engine variants including Ingenium and AJ-V8.
After ECU replacement, the immobilizer system must be synchronized with the BCM, KVM, and key fobs. This requires security access and official JLR software. We provide remote synchronization services for workshops that have the hardware but lack the security credentials.
Engine remap and performance calibration files for select JLR models. These are not generic tunes — they are developed specifically for JLR Bosch MED17 and MG1 ECU architectures. Power and torque gains vary by engine and model.
TCU modules and programming for ZF, Jatco, and Getrag transmissions used across the JLR range.
Replacement transmission control units for ZF 8HP, 9HP, and dual-clutch applications. Each TCU is tested and loaded with the correct transmission calibration for your specific model. Pre-programmed and virgin options available.
Update transmission software to resolve known shift quality issues, jerking, or premature clutch wear. JLR periodically releases transmission calibration updates. We can flash the latest approved version or a specific known-good version.
After TCU replacement or major transmission work, the adaptive learning values must be reset and relearned. This process teaches the TCU the clutch fill times and shift characteristics of your specific transmission. We guide you through the procedure or perform it remotely.
Modules and programming for AWD, terrain response, air suspension, and dynamic chassis systems.
Power transfer unit control modules for Range Rover, Discovery, and Evoque AWD systems. Manages torque split, differential locking, and terrain response integration. We provide replacement modules with pre-loaded terrain response calibration.
Controls air spring inflation, ride height adjustment, and damping. Common failure causes vehicle to drop to bump stops or display suspension fault warnings. We supply replacement modules with height calibration data.
The DSC module coordinates ABS, traction control, and stability intervention. It communicates with steering angle sensors, wheel speed sensors, and yaw rate sensors. Replacement requires sensor calibration and steering angle initialization.
The terrain response control unit manages drive modes: General, Grass/Gravel/Snow, Mud/Ruts, Sand, and Rock Crawl. Each mode adjusts throttle response, transmission behavior, and differential settings. Replacement requires terrain calibration programming.
Powertrain modules require precise programming. We provide the tools, software, and expertise to ensure every module is correctly configured.
Genuine JLR DOIP VCI programming using official Pathfinder and SDD software. This is the same method used by JLR dealerships. Supports all powertrain modules including ECU, TCU, PTU, and chassis control.
For modules that cannot be programmed in-vehicle, our SX-tool supports bench programming. This is especially useful for ECU cloning, immobilizer bypass, and forced programming of locked modules.
We can guide your workshop through powertrain module programming via remote desktop. You provide the vehicle and tools; we provide the expertise and security access. Available worldwide.
