Maximum Vehicle Speed Limit Correction for Jaguar & Land Rover

Name: Maximum vehicle speed limit correction
SKU: 1187
Price: 100.00 USD
Availability: InStock

You drive a Jaguar or Land Rover engineered to perform far beyond the speed your factory configuration currently allows. Whether the factory set a 155 mph (250 km/h) limit for your market, or a lower threshold tailored to a specific tyre specification or regional regulation, the vehicle carries hardware that can deliver more. Maximum Vehicle Speed Limit Correction from LR-Retrofit unlocks that capability through precise software configuration — no hardware swaps, no ECU replacement, no compromise on vehicle integrity.

What This Service Delivers

This service corrects the maximum vehicle speed limit stored in your vehicle’s Car Configuration File (CCF). JLR stores the speed limitation value at CCF address 0x0727 (block 0x07, byte 2), alongside the Powertrain Elements 2 flag at 0x3F44. We edit these values against your vehicle’s As-Built record and code them to your VIN over the OBD diagnostic port[reference:0]. The correction holds through ignition cycles and integrates seamlessly with your vehicle’s existing powertrain and chassis management systems[reference:1].

You select the target speed limit that suits your driving environment. Common configurations include:

250 km/h (155 mph) — the standard JLR high-performance ceiling
210 km/h (130 mph) — a balanced touring setting
190 km/h (118 mph) — a conservative highway setting
Custom values — we work with you to define the correct parameter for your requirements

Vehicle Coverage

This correction supports the full current JLR model range. The service applies to vehicles where the speed limitation parameter exists in the CCF and the supporting hardware is fitted. Coverage includes:

Model Line	Platform	Model Years
Range Rover / Range Rover Sport	L405 / L494	2013–2022
Range Rover / Range Rover Sport	L460 / L461 (MLA)	2022–2026
Discovery / Defender	L462 / L663	2015–2026
Discovery Sport / Evoque	L550 / L551	2015–2026
Jaguar XE / XF / F-Pace / E-Pace / I-Pace	X760 / X260 / X761 / X540 / X590	2015–2026

Availability depends on market specification and fitted hardware. We verify your VIN before any change and confirm the valid range for your vehicle. This ensures we apply only values that match your vehicle’s factory-supported configuration[reference:2].

Why You Would Choose This Correction

Several scenarios make this service the right choice for JLR owners:

Autobahn driving — if you regularly travel on unrestricted German motorways, the factory setting may hold you below the speed your vehicle can safely sustain
Tyre specification changes — JLR applies different speed limits based on factory tyre fitment; a change in wheel specification may warrant a matching revision of the limit
Track use — closed-circuit environments allow speeds the road-going configuration does not anticipate
Regional market differences — vehicles imported across markets often carry a limit that does not match the owner’s new operating environment

In each case, the vehicle’s powertrain, braking system, and chassis components retain their full engineering capability. The correction simply aligns the digital limit with the physical reality of what the vehicle delivers.

How the Process Works

We complete the entire process remotely. You need three things: a Windows laptop, an ENET or DOIP-compatible OBD adapter, and a stable power supply for your vehicle. We handle the rest through a secure remote session.

VIN verification — you send us your VIN; we check the As-Built record and confirm the exact parameter values valid for your vehicle
Secure order confirmation — we confirm the correct target limit with you before proceeding
Remote session setup — you connect the adapter to your OBD port, establish an internet connection, and share the session
CCF edit and verification — we write the corrected values over OBD, then verify the change against your As-Built record
Test and handover — we confirm the setting holds through an ignition cycle, and you drive away with the corrected limit active

No parts are required. The entire correction is a software configuration change coded to your VIN[reference:3].

Technical Foundation

This service relies on JLR’s own configuration architecture. The Car Configuration File is the master feature list stored in your vehicle, and every JLR model from 2010 onward supports CCF-level parameter editing through the engineering interface[reference:4]. We work with the same parameter addresses and value tables that JLR uses in production and in-service configuration. Your vehicle’s As-Built record remains consistent because we write the change back against that record, preserving the integrity of the VIN-linked configuration[reference:5].

Where your vehicle requires Engineering Mode access to reach the speed limitation parameter — common on Jaguar XK/XKR and certain F-Type models — we handle that elevation as part of the service[reference:6]. You do not need to source your own tools or software.

Compatibility Notes

This correction works on vehicles with the factory speed limitation parameter present in the CCF. Some very early or very late production variants may require an alternative approach; we confirm compatibility by VIN before accepting an order. Vehicles fitted with Intelligent Speed Limiter (ISL) or Automatic Speed Limiter (ASL) retain those driver-assistance functions — this service corrects the underlying vehicle maximum speed, not the driver-selectable limiter settings[reference:7].

You should always drive in compliance with local traffic regulations. This service corrects a vehicle configuration parameter; it does not authorise you to exceed any legal speed limit. We provide it for owners who operate their vehicles in environments where higher speeds are lawful and appropriate.
