Land Rover ECU Tune | Viezu USA

These tunes are built to match the engineering precision Land Rover puts into every platform — and to unlock what these vehicles are genuinely capable of.

Tune Types Available

Stage 1 — OBD Tune
No hardware modifications required. Tuned directly through the OBD port. The most accessible entry point across all Land Rover platforms. Meaningful torque and power gains on 3.0L, 5.0L, and diesel variants without a single hardware change.

Stage 2 — Supporting Modifications Required
For vehicles running upgraded supercharger pulleys, intercooler upgrades, exhaust, or other supporting hardware. Stage 2 extracts everything your modifications have to offer with a calibration built around your exact setup. Contact us before ordering to confirm your build is Stage 2 ready.

3.0L Supercharged V6 Performance Tune
Purpose-built for the AJ126 3.0L supercharged V6 — the engine found in Range Rover, Range Rover Sport, Velar, and Discovery models through 2021. Improved throttle response, stronger mid-range torque, and better overall drivability in a way you'll feel from the first drive.

5.0L Supercharged V8 Performance Tune
Built for the AJ133 5.0L supercharged V8 — powering the Range Rover, Range Rover Sport SVR, and Defender V8. These calibrations are developed around the supercharged V8's broad torque curve, delivering stronger output across the entire power band with a more immediate throttle character.

3.0L Mild Hybrid I6 Performance Tune
For the newer P360 and P400 Ingenium inline-6 mild hybrid platforms found in 2020+ Defender, Discovery, Velar, and the L460 Range Rover and Range Rover Sport. Improved power delivery and throttle response from the electrified drivetrain's calibration.

Diesel Performance Tune
Purpose-built for the Td6 V6 diesel (2016–2019), D300, and D350 inline-6 diesel platforms. Improved torque delivery, stronger throttle response, and better pulling power — purpose-built for towing, off-road, and high-mileage operators who depend on their diesel's reliability.

Diesel Economy Tune
Calibrated specifically for fuel efficiency on Land Rover diesel platforms. Real-world MPG improvements without compromising drivability. A strong option for fleet operators, high-mileage Discovery and Range Rover owners, and anyone using their Land Rover as a daily driver or tow vehicle.

Economy / MPG Tune
Optimized for real-world fuel efficiency on petrol platforms without sacrificing drivability. Popular with Range Rover and Range Rover Sport owners looking to reduce fuel costs on the supercharged V6 and V8 platforms.

Important Notes

• 2020+ Land Rover platforms may require an ECU unlock before tuning can be performed. The ECU must be bench-flashed to remove the factory security layer prior to calibration — additional charges and turnaround time apply. Contact us before ordering so we can confirm the unlock process and total cost for your specific vehicle before you spend a dollar.
• Defender V8 5.0L SC (2022+) is a newer platform with specific calibration requirements. Pre-order consultation recommended.
• P360 / P400 mild hybrid platforms require calibration that accounts for both the combustion and mild hybrid systems working together. Contact us before ordering to confirm the correct approach for your specific variant.
• Stage 2 requires a pre-order consultation. We also stock Land Rover and Range Rover performance parts including supercharger pulleys and supporting hardware — ask us about combining a hardware and tune package for maximum results.
• Emissions compliance is your responsibility. Tuning may affect emissions output. Off-road and track use only where applicable by law.
