3.0 Ingenium I6 Diesel D300 Upgrade to D350 Factory Versions for Range Rover
Product Technical Overview
This exclusive factory power calibration service is developed for all 2020 Model Year and newer Range Rover models fitted with the 3.0 Ingenium AJ20D6 inline-six 48V mild hybrid diesel powertrain. JLR equips identical full mechanical hardware for both D300 and D350 variants, including twin variable geometry turbochargers, 2500bar high-pressure fuel injection systems, standard intercoolers, DPF exhaust aftertreatment assemblies, shared cooling circuits and matching drivetrain components. The only performance limitation is locked factory ECU power mapping, which we unlock with genuine JLR-compliant programming without any physical hardware modification, engine teardown or aftermarket remapping.
Stock D300 factory calibration delivers 300 hp / 650 Nm peak torque with a 0–100km/h acceleration time of 7.4 seconds. After official D350 mapping activation, the powertrain unlocks full factory-rated 350 hp / 700 Nm torque, cutting 0–100km/h sprint to 7.1 seconds. Throttle response, low-end pulling power and towing capability are significantly improved, while all OEM emission limits, DPF regeneration logic, engine protection parameters and original vehicle warranty compatibility remain fully preserved.
Before carrying out any factory ECU flash, our technicians conduct a full vehicle hardware audit covering the complete engine assembly, boost system, high-pressure fuel & injectors, cooling package, air intake, exhaust DPF/catalyst, emission control modules, automatic gearbox, prop shafts, transfer case, differential units and factory brake system. Only after passing full system compatibility analysis will we proceed with the D350 calibration activation, eliminating mechanical mismatch risk and post-upgrade fault codes.
Service Operation Rules & Tool Support
This is a software-only OEM upgrade solution. All on-site wiring, adapter connection and ignition setup work must be completed independently by the customer, who bears all operational risks during remote programming. Two official activation channels are available for clients:
- Local activation: Use JET Pro / JET Master JLR Engineering Tool paired with genuine Enet DOIP adapter to complete ECU mapping offline;
- Remote activation: Submit support ticket to our technical team for encrypted online remote programming via TeamViewer.
OEM spare part shipping fees will be calculated separately based on the delivery address if hardware add-ons are required. Full technical documentation covering equipment specs and operation steps is accessible via the dedicated information link on our website.
Step-by-Step Remote Activation Process
- Submit your full vehicle VIN for factory build sheet cross-check and hardware compatibility validation;
- Complete secure online order confirmation via PayPal payment channel to lock VIN-exclusive D350 calibration file;
- Install TeamViewer desktop software on your Windows laptop and share the secure remote ID + password to our certified JLR technicians;
- Switch vehicle ignition to ON power mode (engine off), connect genuine JLR Enet adapter between laptop and vehicle OBD2 DOIP port;
- Our team executes factory-standard ECU map flashing, full module network synchronisation and DTC fault clearing, then completes automatic system self-test;
- After calibration verification, your Range Rover runs on full D350 factory power output with all original vehicle functions intact.
