PLUG-IN HYBRID 3.0 PETROL POWER UPGRADE FROM P440E TO P510E

Factory JLR calibration. Genuine P510e performance. Fully reversible.

Your P440e already carries the hardware. The P440e and P510e 3.0-litre straight-six plug-in hybrid powertrains share a 100% identical technical configuration — same engine internals, same 105kW electric motor, same 38.2kWh battery, same 8-speed automatic transmission, and same driveline[reference:0]. JLR differentiates the two variants exclusively through engine control module software. This upgrade activates the dormant P510e factory calibration already resident within your vehicle’s OEM firmware[reference:1]. You gain the full factory P510e specification without altering a single mechanical component.

Performance Transformation: P440e vs. P510e

These figures reflect JLR’s published factory specifications for both variants[reference:2][reference:3]. The P510e calibration sharpens throttle response, sustains torque delivery across a broader rev band, and leverages the electric motor’s instantaneous torque fill to deliver a measurably more urgent driving experience. Fuel consumption under normal driving remains close to the P440e factory baseline because the upgrade preserves OEM fuelling behaviour[reference:4].

What the Upgrade Delivers

• Genuine factory calibration: We upload JLR’s own P510e software map — not a third-party remap, piggyback, or custom tune. The calibration originates from JLR’s production database and maintains manufacturer specifications[reference:5].
• Dormant OEM map activation: Every stock P440e PCM already contains the higher-output P510e mapping. The upgrade unlocks this pre-loaded calibration through precise recalibration of powertrain control and hybrid control unit logic[reference:6][reference:7].
• Complete reversibility: The process modifies only the software calibration within the engine control module. You can restore the original P440e calibration at any time[reference:8].
• No physical modifications: The upgrade requires no hardware changes, no bolt-on components, and no engine disassembly. Your vehicle retains its original mechanical integrity.
• Hybrid system integrity: The calibration manages battery discharge rates and hybrid power delivery to P510e factory parameters, preserving the plug-in hybrid system’s operational envelope[reference:9].

Technical Process: JLR DoIP and Pathfinder Standards

We perform the upgrade using the same diagnostic protocols and software infrastructure that JLR dealerships and production lines employ. The procedure runs through the vehicle’s ENET diagnostic port using JLR Pathfinder DoIP (Diagnostics over Internet Protocol) standards[reference:10][reference:11]. This approach ensures the correct factory target calibration reaches the PCM and HCU, maintaining diagnostic integrity and long-term powertrain reliability[reference:12].

Before any calibration upload, we conduct a comprehensive compatibility analysis. We compare engine hardware, boost system, fuel supply, cooling, intake, exhaust, emission controls, transmission, driveline, high-voltage battery, inverter, and charging system to confirm the vehicle supports the factory P510e target version[reference:13]. We verify your VIN against the JLR database to guarantee the correct software package for your specific model year and market configuration.

Vehicle Compatibility and Requirements

This upgrade applies to JLR vehicles fitted with the 3.0-litre petrol plug-in hybrid powertrain in P440e specification, primarily 2022MY–2023MY Range Rover and Range Rover Sport (L460/L461) derivatives[reference:14][reference:15]. Because JLR produced multiple PHEV variants across model years and markets, VIN verification is mandatory before purchase. Submit your VIN during checkout, and our technical team will confirm compatibility and the correct factory target calibration before processing your order.

Warranty and Compliance

JLR’s warranty terms exclude unauthorised performance modifications that alter engine management systems[reference:16]. This upgrade uses genuine JLR factory calibration data and JLR-approved diagnostic protocols, preserving the vehicle’s OEM software architecture. The procedure leaves no physical trace and remains fully reversible. We recommend reviewing your specific warranty terms and discussing the calibration with your authorised JLR dealer before installation. We provide full documentation of the calibration process for your records.

Ordering and Installation

1. Submit your VIN — our team verifies compatibility and identifies the correct P510e factory target version for your vehicle.
2. Receive your calibration package — we prepare the JLR factory software and provide installation guidance.
3. Remote or in-person installation — the calibration uploads through the ENET diagnostic port using JLR Pathfinder standards, typically within a single service session.
4. Post-upgrade verification — we confirm successful calibration and provide documentation.

Unlock the performance your P440e already possesses. The factory P510e calibration is already inside your vehicle. This upgrade simply activates it with the precision and reliability that JLR engineering demands.
