– Preparation

Before installing the RaceChip, please wait for your engine to cool down. Otherwise
there is a risk of sustaining burns.

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.

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.

• 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.

Step 2 of 6 – 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.

• If there is no cover on your engine, you can proceed directly to step 3.

Fuse

The Fuse

The fuse allows the vehicle to be restored to its factory settings without the need to
remove the RaceChip wiring harness. When you look at the cable harness, you can see

a blue fuse on the red „+“ cable. As soon as you remove this fuse, your car is reset to
the original condition (without tuning).

Before you decide to put the vehicle to its factory settings, please ensure that there is
no electrical voltage present (see notes on step 1).

• 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.

• 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.

Step 5 of 6 – Fixing RaceChip and wiring harness

• Before  xing the RaceChip in place in the engine bay, ensure that the wiring harness can also
be routed and  xed securely without putting it under excessive tension.

• Use the 360°  xing clips included to  x the RaceChip and thread the cable ties through the
 xing clips to hold the wiring harness in place.

Step 6 of 6

• Route the cable along a suitable path (for example, along existing wiring harness) and then
fasten it using the supplied cable tie.

• 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.

• Re-attach the cover of your engine and close the bonnet.

• The basic installation is now complete and the RaceChip can be used.

• 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).

Opening the RaceChip

4 Fine tuning

The RaceChip has been calibrated specifi 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 jumper bar (see Overview of the RaceChip) allows you to fi ne tune the RaceChip quickly and
easily, letting you get the best from your RaceChip-enhanced engine.

Fine tuning may be necessary if the following occurs:

Using an 8 TORX key, unfasten the two screws on the font side and two screws on
the back side of the RaceChip. You can now open the housing.

Engine idles more roughly than in stock tune.

Use the jumper to change mappings only with the ignition switched on but without
the engine running.

• When delivered, the red jumper is at the middle mapping-step.

• First go with the red jumper two mapping-steps to the left.

• Take your car for a test drive. If the engine performs as smoothly as you want, i.e. no

hesitation or knocking, go one mapping-step to the right and go for another test drive.

• If the engine still performs as smoothly as you want, repeat the previous step and go one
mapping-step to the right.

• If the engine does not perform as smoothly as you want with one of the mappings, go one
mapping-step back to the left – 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).

Making the enhanced performance more noticeable

Use the jumper to change mappings only with the ignition switched on but without
the engine running.

• When delivered, the red jumper is at the middle mapping-step.

• First go with the red jumper two mapping-steps to the right.

• Take your car for a test drive. Go only one mapping-step to the right if you do not experience

the enhanced performance strongly enough.

• If the engine does not perform as smoothly as you want, go one mapping-step back to the
left.

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

B

).

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

A

).

• 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 A).

• 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.

• Select the next lowest mapping and go one mapping-step to
the left(see Fine tuning, section A). 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.

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. 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
remove the orange fuse on 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 A). 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, switch the engine off while leaving the
ignition on, follow the steps described in Fine tuning (section

A

) 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

A

) to activate the right mapping.

• If the fault light is still on, please remove the orange fuse on
the wiring harness. 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).

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 matches the description but you still
do not see any fuel savings, please select the next highest
mapping and go one mapping-step to the right (see Fine

tuning, section B). After selecting a new mapping, check the

actual consumption to see if there has been any reduction.
