JLR KM to MPH Conversion Module Programming & Coding for Land Rover & Jaguar

JLR KM to MPH conversion programming changes your Jaguar or Land Rover display units from kilometres to miles. Vehicles imported from Japan, Europe or other metric markets often reach their new home with a speedometer that reads in kilometres per hour. The hardware performs perfectly, yet the display no longer matches local road signs, speed limits or odometer conventions. LR-Retrofit performs this conversion through licensed software coding within your vehicle’s Central Configuration File (CCF) and Instrument Cluster Module (IPC). We use official JLR diagnostic tools and calibration data. Your vehicle then displays speed in MPH, distance in miles and related values in the units your market expects.

What KM to MPH Conversion Delivers

The conversion changes how your vehicle presents measurement data rather than how it operates. Every gauge, warning lamp and control function continues to work exactly as before. The display units shift instead, which brings your vehicle into line with its current market.

The service adjusts the primary displays that drivers read every journey. The speedometer dial or digital readout switches from KM/H to MPH. The odometer records distance in miles. The trip computer reports fuel consumption in MPG, range in miles and journey distance in miles. The navigation system follows the same change, with route distances and speed limit displays presented in miles.

We also align the secondary displays that owners notice over time. Temperature readouts switch between Celsius and Fahrenheit where the platform links the two settings. Tyre pressure displays adopt the correct unit. Climate control, fuel economy and service interval displays all adopt the convention your market uses.

Displays We Convert

Display	Before Conversion	After Conversion
Speedometer	KM/H	MPH
Odometer	Kilometres	Miles
Trip computer distance	Kilometres	Miles
Fuel consumption	L/100 km	MPG
Range display	Kilometres	Miles
Temperature	Celsius	Fahrenheit where platform links units
Navigation distances	Kilometres and metres	Miles and yards
Tyre pressure	kPa or bar	PSI

How the System Works

Your vehicle’s Instrument Cluster Module (IPC) manages the primary display output. The module reads unit and market parameters from the CCF at start-up, then renders every value according to those settings. The Accessory Protocol Interface Module (APIM) holds the corresponding parameters for the navigation and infotainment displays.

JLR assigns each vehicle a market code at the factory based on its original destination. That code determines the default unit set across every module. When a vehicle moves to a different market, the code no longer matches local conventions. We modify the relevant CCF parameters and write the updated configuration to the IPC, the APIM and any dependent modules.

Odometer handling requires particular care. The stored distance value remains in the unit your vehicle originally recorded, and the display converts it for presentation. Your true vehicle mileage therefore stays intact, and it simply appears in miles after the conversion. We record the pre-conversion and post-conversion readings in your written summary for complete transparency.

KM to MPH Conversion and Speed Limiter Correction

Some markets apply a maximum speed restriction alongside their metric display convention. Japanese-market vehicles commonly carry a 180 km/h limit, for example. Where your vehicle needs both the display conversion and a market specification correction, we complete both during the same session. This combined approach leaves your vehicle fully aligned with its present market, and it avoids a second workshop visit.

Activation Process

LR-Retrofit performs KM to MPH conversion programming through professional software coding. This approach delivers several clear advantages:

• Software-based conversion — your existing cluster and display hardware stays in place.
• Factory-compliant coding — we modify your vehicle’s CCF using licensed JLR diagnostic tools and official calibration files.
• Complete in under one hour — the process is fast, efficient and fully reversible.
• Full documentation — you receive a written record of every value we change, including odometer readings.

We complete the work at our workshop or through remote coding, depending on your location and vehicle setup.

Note: This service changes the unit of display and does not alter the vehicle’s true recorded mileage. We document the odometer reading before and after conversion for complete transparency. Please confirm local registration and disclosure requirements before booking, because several jurisdictions regulate odometer and import documentation directly. Drivers remain responsible for lawful and safe vehicle operation at all times.
