If you drive a modern Land Rover Defender, Discovery 5, or Range Rover equipped with the 3.0L straight-six Ingenium diesel engine (AJ300), we have some incredible news.
For years, these fantastic mild-hybrid (MHEV) luxury powerplants were locked down tight from the factory. Equipped with highly encrypted, ultra-secure Bosch MD1-series ECUs (specifically the MD1CP007), traditional tuning methods simply couldn't touch them. Many owners were stuck with standard performance or forced to resort to risky, generic "tuning boxes" that fool factory sensors.
The wait is officially over. EvoTorque Performance Tuning has cracked the code.
Thanks to a massive software development breakthrough, we can now safely, reliably, and completely rewrite the calibration files directly via your vehicle’s OBD2 diagnostic port—no physical ECU removal, no opening the casing, and zero risk to the hardware.
The Secret JLR Doesn't Want You to Know
Whether your vehicle has a D200, D250, or D300 badge on the tailgate, you are sitting on an identical 3.0-litre straight-six mechanical block.
Jaguar Land Rover limits the power on lower-tier models entirely via factory software maps to separate their retail price points. The D200 is heavily restricted, meaning you are paying premium road tax for a engine that is running at a fraction of its true capability.
Because our custom remapping works directly with the core engine management map, EvoTorque can safely unleash the exact same premium performance across the entire range.
Real-World Testing: The Defender 110 on the Dyno
We don't deal in generic files or guesswork. Every single software upgrade we install is fully calibrated and live-data logged. When putting the iconic Land Rover Defender 110 through its paces on a 4WD rolling road dyno, the results are nothing short of breathtaking.

The Performance Gains: What Can EvoTorque Achieve?
By removing JLR’s artificial software restrictions, our Stage 1 Custom Remap transforms how these heavy vehicles drive. Throttle lag is completely eliminated, and mid-range overtaking power becomes relentless.
