Introducing the Just Map It Tool
TD5 diagnostics and supported remote tuning
Just Map It combines TD5 diagnostic, programming and supported tuning functions in Windows software with an Empire OBD cable. Choose the hardware/software package, a custom-tune package or a dual-mapping package according to the work you need.
Compare Just Map It packages and current prices. Check the selected package, immobiliser option and switch before ordering; the lowest displayed price does not include every option.
Check the ECU first
Diagnostics and writing tuning files are different functions. A standard MSB ECU may need preparation or an upgrade before remote flashing; NNN and upgraded MSB ECUs need the appropriate supported configuration. Send us an ECU-label photograph and details of previous work if you are unsure.
For on-site assessment or ECU work, see our TD5 remapping service. Postal turnaround depends on the work and workload and is confirmed when booking; ask us about priority availability and price.
Key Features that Redefine Td5 Tuning
Unlike other ECU flashers, the Just Map It tool goes above and beyond with a comprehensive, menu-driven interface that simplifies complex tuning and diagnostics. Let’s break down its most remarkable features and how they can transform the way you interact with your Land Rover Td5 engine.
High-Speed Engine Data Logging
At the heart of tuning and diagnostics lies the need for live data logging, and Just Map It excels in this area. The software allows you to log high-speed engine data with selectable parameters for in-depth performance analysis. Real-time data is displayed in an intuitive format, making it easier than ever to monitor your Land Rover’s health and performance. You can also save this data and export it directly to us so we can help in tuning/diagnosing your TD5 remotely!
In our YouTube video, we show how quickly you can set up the data logging interface and begin capturing key engine performance metrics.*
Read and Clear Fault Codes
No more guesswork when diagnosing issues with your Land Rover Td5. With Just Map It, you can read and clear fault codes in seconds, and even view sensor voltage levels for more precise fault-finding. This feature ensures that any potential problems are caught early, saving you time and money on repairs.
Programming, dual mapping and recovery
Supported NNN programming functions include VIN programming and full ECU file handling. Immobiliser functions depend on the ECU and selected service; confirm what is required before ordering optional work.
Dual-map switching requires a suitable ECU configuration, the purchased dual-map package and the correct external switch. Remote setup may be possible on a prepared ECU; do not assume every standard MSB ECU can be updated remotely without prior work.
Recovery support depends on the ECU configuration and the nature of the fault. A recovery function cannot guarantee that a physically damaged ECU can be repaired or that replacement will never be necessary. Contact us before attempting recovery if you are unsure.
Full ECU Read, Write, and Verify Capabilities
With full ECU read/write/verify functionality, you can access and modify all maps and firmware on NNN Td5 ECUs. This feature gives you complete control over your vehicle’s performance, allowing you to fine-tune every aspect of your Td5’s engine management.
ECU Input/Output Testing
Testing your ECU’s functions is crucial for maintaining optimal performance. The Just Map It tool provides comprehensive input/output testing for all major ECU functions, ensuring your Td5 engine is running at peak efficiency.
10AS Immobiliser on Defender Modification
