ECU Remapping for Range Rover Sport 3.0 Supercharged Petrol V6
This Range Rover Sport 3.0 V6 supercharged petrol ECU remap is built for drivers who want sharper throttle response, stronger mid-range pull, and smoother power delivery in real UK driving.
We install a VIEZU ECU remap and apply a vehicle-specific calibration for your engine and software version. This is a professional remapping service carried out by Powerhouse technicians, not a generic one-file-fits-all flash.
This listing is for petrol 3.0 V6 supercharged models only. Diesel Range Rover Sport remaps are listed separately.
What ECU Remapping Changes
The ECU controls key engine strategies including throttle mapping, ignition timing, torque request, and boost control. Manufacturers keep factory calibrations conservative to suit worldwide conditions and long service intervals.
A properly built ECU remap optimises these settings for UK driving and fuel quality. The goal is a better driving Range Rover Sport, not unrealistic peak numbers.
What You Can Expect After the Remap
Most customers notice the biggest improvements in how the vehicle drives day to day.
-
Faster, cleaner throttle response
-
Stronger mid-range torque and smoother acceleration
-
More relaxed overtaking and motorway driving
-
Improved drivability, especially in normal road conditions
Fuel economy can improve when driven sensibly, but on a supercharged petrol engine it depends heavily on driving style.
Engine and Vehicle Fitment
This remap is for the Range Rover Sport 3.0 V6 supercharged petrol used across the 2012 to 2018 listing range. This engine is widely known as the AJ126 3.0 supercharged V6 and was offered by JLR in several factory power levels, with tuning potential across those variants.
If you are unsure whether your vehicle is the correct engine, contact us with your registration and we will confirm compatibility before booking.
