Land Rover Td5 ECU Services – Immobiliser Removal

We offer a complete professional service for the Bosch MSB and NNN Td5 ECUs fitted to Land Rover Discovery 2 and Defender Td5 models. Whether you’re experiencing immobiliser issues or looking for improved performance, we can help.

Services Offered:

Immobiliser Removal (“Immo Off”)
Removes the immobiliser function from the ECU, eliminating common no-start issues and allowing the vehicle to run without matching the original security system.

Convert Auto ECU to manual
Extra components are needed for the ECU to understand the input from the clutch switch to help with smooth gear changes. These components are added to the ECU before it is returned to you.

Performance Remapping
Tailored ECU remaps for improved torque, smoother power delivery, better drivability, and potential fuel economy gains. Options available for Stage 1, Stage 2, and custom tuning depending on modifications.
