How does Unichip increase engine power? 
Every engine requires optimum ignition timing
and air fuel ratio at all RPM and load conditions.
unichip gives the experienced Dynamometer technician
the access to and ability to adjust and optimize
both the ignition and fuel system. Unichip has
17 RPM sites between 500 RPM and 8000 RPM and
12 load sites between zero throttle position and
wide-open throttle position. This equates to 204
possible adjustments for fuel and a further 204
adjustments for ignition timing.
How much extra power can I expect from Unichip?
Power gains of 10 KW to 30 KW are common place,
as measured by an accurate chassis dynamometer.
Whilst less common, power gains of 50 KW have
been verified. The exact power gain however depends
on the design and condition of the engine and
the factory calibration of the engine control
unit. No two engines are identical. The Unichip
results represent the optimization of each individual
engine. Unichip results are verified by before
and after dynamometer tests measured at 100% throttle
opening across the entire RPM range.
Will Unichip improve my car's
fuel economy?
Yes. In most driving conditions, Unichip will
improve fuel economy. Many modern fuel injected
engines waste fuel by running very rich air fuel
ratios at part throttle openings. With Unichip,
it is a simple procedure to correctly adjust the
air fuel ratio over 12 throttle positions and
maximize the fuel economy for cruising at part
throttle.
How is Unichip different from "performance
chips"?
Unichip is a supplementary engine management
systems. As such, it is far more advanced than
"generic plug-in performance chip" products.
It is individually programmable to meet the requirements
of engine and driver. Being fully adjustable,
Unichip can cater for non-standard, current and
future engine modifications. Best of all, unichip
can deliver the most personalized power result
every time - uniquely tuned for fuel type and
rating, and even particular ambient conditions
of operation.
What are the engine management advantages of
Unichip?
Unlike many other engine management systems,
Unichip does not alter the cold start, knock sensors,
water temperature sensors, air temperature sensors
or oxygen sensors. All remain genuine components.
A major advantage of Unichip is that it works
in harmony with the factory ECU to enhance and
unleash the best possible performance result without
compromising engine durability.
Is the original factory engine
control unit modified by installing Unichip? 
No. Unichip is a supplementary computer which
is programmed to contain the optimum fuel and
ignition adjustments for each individual engine.
the factory engine management control unit is
not altered in any way. The Unichip is simply
installed by connecting to the wires of the original
factory ECU.
Is Unichip suitable for al EFI
cars?
Most EFI cars, whether normally aspirated, turbocharged,
supercharged, with 4, 5, 6, 8, 10 or 12 cylinders
respond brilliantly to Unichip enhancement.
Unichip real-time tuning - What does this mean?
Real time tuning describes the process whereby
adjustments are made to the ignition timing and
air fuel ratio whilst running the vehicle on a
dynamometer. In doing so, the technician can optimize
power output at any RPM point. For example, if
we run the vehicle at 2,000 RPM, we can increase
the ignition timing to the point of maximum power
before reaching combustion detonation. The same
practise applies to the air fuel ratio. We can
clearly see, by watching the dynamometer power
graph, what air fuel ratio produces the highest
power at 2,000 RPM.
Is it safe to tune my car on a Dynamometer?
Yes, it is safe. A dynamometer does not create
any greater load on the engine than what you experience
in normal driving conditions. Very efficient cooling
fans are utilized to ensure safe engine temperature
control.
Does the Unichip need to be serviced or retuned?
There is no need to readjust the Unichip unless
the engine has been modified. It is nearly impossible
for the Unichip data to change after the Unichip
ECU has been programmed, causing the engine to
be detuned. It is possible however for the fuel
pressure to drop (if the fuel pump deteriorates)
which would cause the engine to run a leaner air
fuel ratio than normal. Other items such as fuel
injectors and spark plugs will need servicing
from time to time which will also change the state
of engine tune.
Should I use unleaded or premium unleaded fuel
with unichip.
Your engine should always be tuned using the
fuel which you intend to use day to day. Premium
unleaded fuel will always produce the best power
result, as it will allow the engine to use all
of the ignition timing in the timing map. As most
modern EFI engines utilize knock sensors, if you
change from premium unleaded to standard unleaded,
the engine's knock sensors will detect detonation
and reduce timing accordingly, resulting in a
loss of power.
Where is the Unichip installed?
The Unichip ECU is usually fastened to the factory
engine control unit using velcro tape. The Unichip
ECU is marginally larger that a cigarette pack.
Dimensions are 160mm length x 80mm height x 20mm
width.
