Range Rover P38

No trade off between fuel economy and increased power!

Replacement ECU chip to improve power and economy on the GEMS engine 4.0 and 4.6 in the Range Rover P38. Fitting this chip will increase economy by approx 15% and power by 10%. Once fitted, it helps makes a big difference to the driveability of the vehicle by improving throttle response and mid-range pull.

Accelerate technology
Limitations and restrictions exist which prevent your vehicle from achieving optimal performance. The manufacturer's emissions test is extremely rigorous due to inclusion of all parts of the driving cycle, especially warm up and full load operation, which is where problem emissions are at a maximum. To meet these they compromise performance and efficiency of the engine - this chip helps redress that balance.

Off roaders in the driving seat
Your requirements are met through a stable and predictable idle quality, good engine braking and an engine which has plenty of midrange torque. Perfect idle control for hill descents and winching, with no possibility of stalling. Total reliability ensures you never lose control.

Greater expectations
By comparison we know climate conditions and fuel quality your vehicle experiences and can therefore improve efficiency by reducing fuel consumption and optimising the engine to get its best performance on full load, which is less than 10% of the time.
