Step 1 of 7 - Preparation
Open your vehicle’s bonnet, and close and lock the doors.
Wait about 10 minutes before starting Step 2, as all current consumers must have
switched themselves off.
• For cars with “Keyless Go”: after locking the car, place the key out of signal range
(about 10 m from the car).
• If an alarm system is tted: disable the alarm before starting installation.
• Some cars will not lock completely if the bonnet is open and electrical consumers
are still active. If this is the case with your car, push the bonnet catch over manually,
lock the car again and wait ca. 15 minutes. When you have nished the installation,
do not forget to release the catch again by pulling the bonnet release lever.
• If you have any questions or difculties during the installation, please refer to
Trouble Shooting for hints and tips.
• Our Customer Service is of course always ready to help. See Contact for details.

Before installing the RaceChip, please wait for your engine to cool down. Otherwise
there is a risk of sustaining burns.
Generally speaking, you do not require special tools to perform the installation. If you
need a tool, we will tell you when you get to the relevant step in these instructions. You
will probably nd wire cutters useful for clipping off the loose ends of cable ties.

Step 2 of 7 - Removing the engine cover
• Remove the engine cover and place it next to the car. You may have to jiggle the cover slightly
to release it from the holding clips.
• In some vehicles it is necessary to loosen one or more screws before you can remove the
engine cover.
The engine cover is held in place by clips (A) or screws (B).
• If there is no cover on your engine, you can proceed directly to step 3.

Step 3 of 7 – Connection to common rail sensor
• First locate the common rail sensor connection in your engine bay.
• The common rail sensor connection is located either at one of the ends of or
centrally on the common rail and can be clearly identied by the large union nut.
• The best way to nd the common rail itself is by following the injection lines. These
always lead directly from the injection system to the cylinders, i.e. they can be
traced back from the engine block.

• Position the RaceChip and the wiring harness safely in the engine bay. Do not  x
anything in place yet.
• Switch the ignition on. DO NOT start the engine.
• Check for the following:
- Control lights on the dashboard light up and go out as normal.
- The Power ON light on the Digital User Interface of your RaceChip lights up (see
Overview of the RaceChip).
• If all the above happens, you can start the engine. It should start as normal and should
react to the throttle when idling.
• Switch off the engine and ignition.

• If your car will not start as normal, please refer to Trouble Shooting for hints and tips.
• Our Customer Service is of course always ready to help. See Contact for details.
• If the Digital User Interface lit up as soon as it was connected, this means that there
was still power in the system during the installation.
• In some cases, this can lead to an error message during the  rst function test. Please
refer to Trouble Shooting for a solution.

Step 6 of 7 – Fixing RaceChip and wiring harness
• If you need to remove the RaceChip at a later date, you can simply release the clips and do
not have to cut any cable ties.

13
• When selecting a fastening point, make sure that the RaceChip is protected from
exposure to water, heat, and vibrations.
• Do not wrap the RaceChip in an airtight bag as this can lead to a built up of
condensation.
• Do not route the cable in areas in your vehicle that become overly hot during
operation (e.g. the exhaust system, turbocharger, etc.).
• Do not route the cable along movable parts.
• Never fasten the cable onto hoses (e.g. a brake hose) as this could result in
abrasion.
3 Installation
Step 7 of 7 - Completing the installation
• Re-attach the cover of your engine and close the bonnet.
• The installation process is now complete and your RaceChip is ready for use.
• Take your car for a test drive. If you have any questions, do not hesitate to contact our
Customer Service department (see Contact for details).
• Route the cable along a suitable path (for example, along existing wiring harness) and then
fasten it using the supplied cable tie.

4 Fine tuning
The RaceChip has been calibrated specically for the engine in your car, and further adjustment
is generally not necessary in order to get the best performance. However, performance
tolerances or the condition of the engine sometimes mean that Fine tuning is needed after
installing the RaceChip.
The Digital User Interface of the RaceChip (see Overview of the RaceChip) lets you carry out the
Fine tuning yourself to get the best from your RaceChip-enhanced engine.
Fine tuning may be necessary if the following occurs:
AEngine idles more roughly than in stock tune.
The Fine tuning mappings can be changed using the +/- buttons only when the
ignition is switched on but without the engine running.
• Mapping 5 is the factory setting.
• First activate Mapping 1.
• Take your car for a test drive. If the engine performs as smoothly as you want, i.e. no
hesitation or knocking, please activate Mapping 2and go for another test drive.
• If the engine still performs as smoothly as you want, repeat the previous step.
• If the engine does not perform as smoothly as you want with one of the mappings, go back
to the previous mapping – this is the right one for your engine.
If your engine does not run smoothly with any of the mappings or if the engine control
light is permanently on after making all the adjustments (and after switching the
ignition off and waiting 15 minutes), please contact our Customer Service (see Contact
for details).
Mapping step -1 Mapping step +1
Engine runs roughly, knocks or “pinks” under load, or the engine warning light comes on.

Mapping step -1 Mapping step +1
4 Fine tuning
Making the enhanced performance more noticeable
The Fine tuning mappings can be changed using the +/- buttons only when the
ignition is switched on but without the engine running.
• Mapping 5 is the factory setting.
• First activate Mapping 6.
• Take your car for a test drive. Activate Mapping 7 only if you do not experience the enhanced
performance strongly enough.
• If the engine does not perform as smoothly as you want, activate the next mapping down
the scale (e.g. from 6to 5).
• Mapping 0 puts the engine into stock tune with the RaceChip installed.
• You can also use the deactivation plug to return you car to stock tune without
having to remove the wiring harness. In order to use the deactivation plug, you need
to remove the RaceChip from the wiring harness connector and replace it with the
deactivation plug.
• Before replacing the RaceChip with the deactivation plug, rst ensure that there is
no residual charge in the car’s electrics (see Step 1).
If the driver does not experience the extra performance, it means the driver cannot feel
the difference from stock tuning.

5 Trouble Shooting
If the RaceChip does not function as it should, you can nd some initial assistance here. If the
suggestions here do not solve the problem, please contact our Customer Service (see Contact).
Description of problem What to do
No extra performance
or performance not
noticeable enough
I am not satised with the
performance level of my
vehicle.
• You can nd detailed instructions on how to make the extra
performance more noticeable in Fine tuning (section ).
Knocking/ rattling
The engine knocks or
rattles (diesel engine)
more under load. It runs
less smoothly than in
stock tune.
• If you have the impression that your engine knocks or rattles
more than in stock tune, please take the car for a few test
drives to be sure that your rst impression was right. On the
test drive, pay special attention to the engine’s behaviour
under load – the RaceChip only works then.
• If your rst impression was right, you can nd detailed
instructions on how to make the engine run smoothly again in
Fine tuning (section ).
• If the knocking/rattling is very noticeable, you can carry out
the steps described in Fine tuning immediately.
Jolting
With the RaceChip
installed, my car jolts,
stutters or hesitates in
situations where it did not
before.
• You can nd detailed instructions on how to make the engine
run smoothly again in Fine tuning (section ).
• If that does not cure the problem, please contact our
Customer Service; if you can describe the circumstances
when the problem occurs, our Customer Service can make
further adjustments.
Quality of gear shift
reduced
The shift behaviour
and/or the shift quality
has worsened since
the installation of the
RaceChip. The gearbox
sometimes cannot seem
to nd the right gear.
• Using the Digital User Interface (see Overview of the
RaceChip), select the next Fine tuning mapping down the
scale. Repeat this procedure until you are happy with the
gear shifting.
• If that does not cure the problem, please contact our
Customer Service; if you can describe the circumstances
when the problem occurs, our Customer Service can make
further adjustments.

5 Trouble Shooting
Description of problem What to do
Engine fault light or
other warning light
comes on and stays
on after installing the
RaceChip.
A warning light on the
dashboard comes
on and stays on after
installation of the
RaceChip.
• If a warning light (e.g engine fault light) comes on, it does
not automatically mean something is wrong with the engine.
The lamp can simply be a measure programmed by the
manufacturer to protect the engine; it can be triggered if a
cable is disconnected from a sensor when there was still
power in the system, for instance. (An indication that this
might be the case is if the Digital User Interface lit up as
soon as it was connected to the car’s electrics; it should only
receive power when the ignition is switched on). Please follow
the steps below carefully until you have found the cause of
the warning lamp and xed it.
• De-install the RaceChip wiring harness to the point that you
can reconnect all the connections in your car as they were
before you started installing the RaceChip. Lock the car and
wait ca. 30 minutes before starting the engine. If the warning
light still stays on, stopping and restarting the engine several
times or waiting for even longer can sometimes help.
• If the warning lights have gone out, you can re-install the
RaceChip. Make sure the ignition is off and wait at least
15 minutes before disconnecting the sensors. When the
installation is complete, double check all the connections to
ensure the connectors are joined correctly and tightly. Please
connect the Deactivation plug to the wiring harness and start
the engine again.
• If the warning lights do not come on, switch off the engine
again and wait for 15 minutes. You can now replace the
Deactivation plug with the RaceChip and start the engine
again.
• If the warning lights come on again now, please contact our
Customer Service (see Contact).
Soot generation
My car produces (more)
soot since installing the
RaceChip.
• You can nd detailed instructions on how to make the engine
run smoothly again in Fine tuning (section ). The steps will
also help stop the engine producing excess soot.

5 Trouble Shooting
Description of problem What to do
Engine fault light comes
on after a while and
stays on
After driving with the
RaceChip (including
acceleration) for while,
the engine fault light
comes on and stays on.
• Please park your car and switch the engine off while leaving
the ignition on. Activate Mapping 1 (see Fine tuning,
section ) and then turn the ignition off. Lock the car and
wait ca. 30 minutes before starting the engine again. If the
warning light does not come on again, you can follow the
steps described in Fine tuning (section ) to activate the
right mapping.
• If the fault light is still on, please activate Mapping 0 or
replace the RaceChip with the Deactivation plug (supplied).
This returns your car to stock tuning. Lock the car and wait
ca. 30 minutes before starting the engine again. Please
contact our Customer Service (see Contact) and tell them
what you see (warning is on/not on).
The car does not start
The car’s ignition does not
work after installing the
RaceChip.
• Something probably went wrong during the installation
procedure. Please follow the steps below to check that the
RaceChip is installed correctly.
• De-install the RaceChip wiring harness the point that you can
reconnect all the connections in your car as they were before
you started installing the RaceChip. (You can leave the wiring
harness in the engine bay; the important thing is that it is not
connected to the vehicle electrics). Lock the car and wait ca.
30 minutes before trying to start the engine again.
• If the car starts, you can re-install the RaceChip. Make sure
the ignition is switched off and wait at least 15 minutes
before disconnecting the sensors in the engine bay. After
installing the RaceChip, double check that all the connectors
are correctly and rmly xed. Go through all the steps
described in Installation again. Finally, start the engine.
• If the car still does not start, please contact our Customer
Service (see Contact).

5 Trouble Shooting
Description of problem What to do
No noticeable fuel
savings
I do not notice any fuel
savings
• Make sure you are comparing before-and-after fuel
consumption based on the vehicle’s actual consumption –
on-board computers often display incorrect values.
• It is important that your driving style remains the same, i.e.
you do not accelerate harder or drive fast more often than
before. You will not see any fuel savings either if you often
drive at or near maximum load – you need to adopt an
economical driving style at least some of the time in order to
save fuel.
• If your driving style is at least partly economical and you still
do not save fuel, please select the next Mapping up the scale
via the Digital User Interface of the RaceChip (see Fine
tuning, section ). After selecting a new mapping, check the
actual consumption to see if there has been any reduction.
