Land Rover engines tuning specialist, B.A.S, has been offering performance remaps for all Land Rover post-1999 using its B.A.S Box device. Recently they introduced a new tool, the BAS2 Remote Remap Control that is not only much smaller and convenient but offers much more options on top of letting you install the performance tune on and off at will.

We tried it on our 3.6L TDV8 Range Rover Sport with great result. The twin-turbo V8 becomes much punchier with 320hp (compared to 272 hp) and torque rises to 513 lb/ft. from 472lb/ft.

When we do not use the extra grunt, the mileage progresses by about 8 to 10%, an achievement itself. We did try to ‘hyper mile’ it with the tune on, you can get to 26 mpg (instead of 24) – but then why would you get a Range Rover – honestly, you’d rather use the extra torque! The tune effectively gets rid of turbo lag but it also gives a significant extra torque in the middle rpm – perfect for overtaking for instance.


That said the tool is much more than a tuning module, it offers engine management diagnostic functionality – best of all, you control it from your phone or tablet! It may be used with Apple iDevice along with all Android ones via Bluetooth. From then, you can read and deleted detailed engine faults, log live engine data (with numerical and graphical charts that you can save as PDF or CSV files.)

Also, the RRC allows the programming of the latest engine calibration files on the ECU (saving a trip to the dealer when updates are needed). Last the tool works on several registered vehicles (fees applies), ideal for multi Land Rover families. Note: Aging Range Rover L322s and Sports now commonly showing intercooler hose failure, B.A.S strongly recommend installing their upgraded silicon hose when opting for a tune.

Verdict: Extra power, the easy way.
