L460 P400 Power Upgrade | Range Rover Sport L460 OEM Coding
Land Rover New Range Rover Sport L460 Activates P400 Power Upgrade
This professional JLR OEM coding service delivers a factory-grade P400 Power Upgrade for the latest Range Rover Sport L460 MLA-Pro 3.0L inline-six MHEV platform. Many entry and mid-level L460 petrol models feature identical B24 engine hardware as the official P400 variant. However, JLR applies strict factory software detuning to limit horsepower and torque output for lower trim levels. For this reason, stock vehicles leave significant factory performance potential locked. Our pure OEM software coding safely unlocks the official P400 calibration map without any hardware modifications.
Unlike risky third-party ECU flashing, this upgrade uses only authentic JLR factory parameters. It preserves all stock engine protection limiters, GPF emission systems and hybrid MHEV logic. In addition, it retains full dealer diagnostic compatibility. As a result, owners gain full P400 power with complete factory reliability and long-term stability.
Technical P400 Upgrade Overview
The L460 3.0L inline-six MHEV engine uses robust forged internal components. It supports far higher performance than stock detuned calibrations allow. Factory restrictions limit turbo boost pressure, fuel delivery and torque output to match lower trim specifications. These software limits cause dull throttle response and weak mid-range acceleration in daily driving.
After our professional P400 activation, the ECU enables full factory power parameters. The engine delivers improved low-end torque and sharper throttle feedback. Meanwhile, it enhances mid-range pull for highway overtaking and dynamic driving. Notably, all factory safety protocols, thermal management and emission controls remain fully functional. Therefore, the upgrade delivers enhanced performance without sacrificing OEM durability.
Vehicle Compatibility & Pre-Check Rules
This coding service supports 2022–2026 Range Rover Sport L460 3.0L inline-six MHEV petrol models. It perfectly upgrades factory lower-powered petrol trims to genuine OEM P400 performance specs. It fits all original hardware configurations with no turbo, intercooler or fuel system upgrades required.
Before every service, we complete a full VIN validation and ECU software inspection. This step confirms current calibration status. It also rules out existing coding conflicts or outdated firmware. Thus, it guarantees a fault-free, stable power upgrade result.
Professional JLR Coding Workflow
Our workflow follows official JLR factory technical standards strictly. First, we create a full backup of your original ECU and CCF calibration data for emergency rollback. Next, we apply targeted OEM parameter tuning via Pathfinder and DoIP professional tools. This process removes factory detune limits and activates the native P400 performance map.
After coding completion, we perform full module resets and system diagnostics. We test idle stability, boost delivery and throttle response across multiple driving cycles. Finally, we confirm zero DTC faults, no dashboard errors and full compatibility with future dealer software updates.
