Tuning Box Tunit Upgrade Chips
DA4507
Tuning box for the Defender - Puma 2.2Tdci
Power increases by 27bhp (20kw)
Torque increases by 71Nm
The 2011 onwards 2.2 Tdci model Defender has new
style piezo injectors and requires specialised tuning
solutions. It is currently not possible to remap the ECU
through the OBD port. This substantial new tuning unit
is designed to plug directly into the wiring loom and
requires no modification to the vehicle. Contained in
waterproof housing so can be safely located in the
engine bay.

The Power Box houses a digital microprocessor which
intercepts the fuelling signals being transmitted from the
ECU to the fuel pump; it then modifies them to ensure
the exact amount of diesel required for enhanced
performance. Such efficient use of the fuel optimises
consumption, reduces smoke emissions and there is less
engine stress, enhancing engine life in many cases.
The Power Box improves torque enabling the vehicle
to change gears earlier and hold higher gears at lower
speeds, making driving more pleasurable.
The unit fits using the original manufacturers plugs; these
existing plugs are opened and the Power Box is secured
in between. Full fitting instructions are included with every
unit.

Tunit Diesel Performance - The Diesel Tunit has been
forged from many years of experience to bring a
world class unbeatable range of diesel performance
solutions.
Tunit Features - Tunit possesses many advantageous
features not seen in other tuning solutions such as
chips, eprom serial reprogramming (flashing) or other
types of fixed map devices. It is interchangeable
between vehicles and able to be upgraded. External
to the ECU or `Plug and play` as it is often called
means no interference with the original manufacturers
engine equipment. Its option to adjust power and
performance provides easy manual adjustment for
the novice or finer electronic alterations for the more
dedicated tuner.
Fuel Savings - Tunit has become advantageous in
reducing fuel costs for a variety of applications; not
just improving performance but now helping with
saving fuel costs.
Installation - The Tunit is normally connected to
original plugs on the vehicle and can either be selfinstalled
or by a professional mechanic.
DA4497 Range Rover P38
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.

No trade off between fuel economy and
increased power!
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.
