D300 to D350 | JLR 3.0L Ingenium MHEV Diesel OEM Performance Unlock
JLR mechanically equips D300 and D350 variants with matching turbo, cooling and fuel system components. Factory CCF and PCM software limits cap D300 power output for trim level separation.
Our professional DoIP programming activates the dormant factory D350 calibration. This pure OEM coding requires no hardware swaps or aftermarket ECU modifications.
It retains full dealer diagnostic access, SOTA updates and factory emission compliance for daily road use.

- Stock D300 output: 300 PS / 650 Nm peak torque
- Unlocked D350 output: 350 PS / 700 Nm peak torque
- Genuine performance gain: +50 PS power and +50 Nm torque
- Compatible platform: EVA2.0 3.0L Ingenium MHEV Diesel (MY21–MY25)
- Updated control modules: PCM, CCF, IPC and central gateway ECU
- Fully retains DPF regeneration and factory emission system logic
- Preserves all factory safety limits and thermal protection protocols
- 100% reversible coding with secure pre-programming CCF backup
JLR Diesel Powertrain Engineering Logic</h2>>
JLR designs the 3.0L Ingenium diesel platform with unified hardware for D300 and D350 trims. All turbocharging, injector and mild-hybrid components carry identical OEM specifications.
Factory software calibration restricts boost pressure and fuel delivery on base D300 models. These limitations create tiered performance levels without mechanical differences.
Our dealer-approved CCF configuration edit removes restrictive parameters. It enables the authentic D350 PCM calibration preloaded within factory firmware.
No safety maps, emission controls or DPF functions are modified during the process.
Real-World Driving & Towing Benefits</h2>>
The D350 OEM calibration improves low-end torque for stronger initial pulling power. Mid-range acceleration becomes more responsive for overtaking and highway cruising.
Heavy-load towing capability sees noticeable improvements for commercial and leisure use. The integrated MHEV e-boost system syncs perfectly with upgraded power parameters.
Stock fuel economy and engine refinement remain unchanged after coding. No aftermarket tuning compromises long-term engine reliability or DPF health.
The instrument cluster updates to display accurate D350 performance metrics for full OEM consistency.
OEM PCM & CCF Programming Procedure</h2>>
Our certified technicians complete a full pre-programming network diagnostic scan. We log all existing DTCs and back up the original factory CCF file.
A compliant DoIP VCI tool connects for secure JLR Pathfinder gateway access. We enable factory D350 powertrain flags and flash official PCM calibration data.
Updated parameters sync across all CAN/Ethernet linked vehicle modules. We clear residual fault codes and validate full network stability.
A final road test verifies smooth diesel power delivery and fault-free operation before handover.
Gain improved acceleration, torque and towing performance without aftermarket compromises. All programming is reversible, dealer compliant and emissions friendly.
