OMEX Rev Limiter TWIN COIL, Rev Limiter SINGLE COIL Installation And User Instructions Manual

OMEX

PERFORMANCE ELECTRONICS

Please ensure that you read this manual thoroughly before you install this unit. In conjunction
with this Rev Limiter, we recommend the use of a high quality shift light, such as the Omex
Shift Light Pro or Sequential.

This Rev Limiter is suitable for most 4-stroke petrol engines and most ignition types, but not
capacitor discharge (CDi) systems or positive earth vehicles. It should only be used to limit
engine revs, never a vehicle’s road speed.

INSTALLATION

Ensure that the ignition is turned off before starting installation.
Remove the backing from the adhesive pad on the back of the unit and mount it to a clean,

flat, grease-free surface. Keep the unit away from hot or exposed areas. Ensure that the

unit and all wires are kept as far as possible from the HT parts of the ignition system.

The unit is connected to the engine using the attached colour coded wires and the supplied
cable connectors.

BLUE WIRE Connect this to the coil negative (-) terminal
RED WIRE Connect this to the coil positive (+) terminal. If this is not easily accessible

then this wire can be connected to any positive feed that is switched by
the ignition switch.

BLACK WIRE Connect this wire to any good electrical connection on the car bodywork.
A self-tapping screw and spring washer are supplied for this purpose if no
bolt heads are within easy reach of the wire. It is essential that a good
quality connection is made.

Keep wires clear of hot or rotating parts using the supplied cable ties.

SETTING UP

The two buttons and LED indicators allow you to set and control all the functions on your
Rev Limiter Clubman. During manufacture, the unit is programmed to the most common
settings. These may be changed by the following procedures:-

CUSTOMER CARE

As part of our commitment to providing the best possible products and after sales service, we operate a telephone Help

the problem.

WARRANTY

OMEX TECHNOLOGY SYSTEMS LTD (OMEX) warrants that if the whole or any part of the REV LIMITER CLUBMAN is
defective as to materials or workmanship, provided that such defect is notified to OMEX as soon as the customer
becomes aware and in any event within one year of purchase from OMEX or one of its distributors, OMEX will make good
the said defect without charge by repair or, at the discretion of OMEX, by replacement. The warranty does not extend to
defects caused wholly or partly by improper use, failure to follow installation or operation instructions, wilful default, act of
God, or accident.
OMEX will not be held liable for any injury, damage, direct or consequential loss, however caused relating to the OMEX
REV LIMITER CLUBMAN.

RESETTING THE REV LIMIT - in order to provide a reference point, you may wish to reset the
unit back to 6,000 RPM and the launch limit to 5,000 RPM. To do so, switch the ignition to the
‘off’ position. Press and hold down both buttons, then turn the ignition on, but do not start the
engine. Both LEDs will flash twice to show the rev limit has been reset. Release the buttons
and the unit will automatically enter into the ‘set’ mode (see previous page).

LAUNCH CONTROL

INSTALLATION

The push button may be mounted anywhere but in the majority of applications the best position
is on the steering wheel within easy reach of the driver’s thumb. It is essential that the wires
have enough slack in them so that they do not become tangled as the steering wheel is turned
from lock to lock.

SETTING UP

To set the launch limit turn the ignition to the ‘off’ position. Press and hold down the launch
button. Whilst still holding the launch button turn on the ignition, but do not start the engine.
The LED indicators will flash three times to confirm this has been done. Release the launch
button. The ‘+’ and ‘-’ buttons can then be used to increase or decrease the launch rev limit.
When the launch rev limit reaches its maximum or minimum (1,000 RPM) possible setting,
both LEDs will flash. When you have reached the required setting either start the engine or
turn the ignition off.

LAUNCH CONTROL USE

Just before leaving the start line it is necessary to bring the engine up to ‘launch’ speed. Press
and hold the launch button (both LEDs on the rev limiter will light to confirm this). Increase the
engine RPM so that it just hits the launch rev limit. Do not use more throttle than is necessary
as this can cause the engine to over fuel. When ready to leave the start line, keep the button
pressed and use as much throttle as is required. When the wheels have stopped spinning let
go of the button and drive as normal.

Do not hold the engine on the launch rev limit for more than 15

seconds as this can cause overheating of the rev limiter

SETTING THE NUMBER OF CYLINDERS

During manufacture, the unit is set to four cylinders. To change this, turn the ignition to the ‘off’
position. Press and hold down the ‘+’ button. Whilst still holding the ‘+’ button, turn the ignition
on, but do not start the engine. The two LED indicators situated between these buttons will
show the cylinder setting (see table below). Let go of the button.

SETTING THE REV LIMIT

The rev limit can be increased or decreased in steps of 100 RPM, allowing for an extremely
accurate rev limit, irrespective of tachometer error. The unit is set to 6,000 RPM during
manufacture. To prevent accidental change of the rev limit, the unit must be put into ‘set rev
limit’ mode. To do this, turn the ignition on -but do not start the engine - then press and hold
both buttons. Both LEDs will flash briefly. Release the buttons.

The ‘+’ button will increase the rev limit by 100 RPM each time it
is pressed and released. LED 1 will flash to confirm this.

The ‘-’ button will decrease the rev limit by 100 RPM each time it
is pressed and released. LED 2 will flash to confirm this.

When the unit reaches its maximum or minimum possible setting, both LEDs will flash. When
you have finished, either start your engine (the new setting will be fully operational) or turn off
the ignition.

For example - The Rev Limiter has a factory setting of 6,000 RPM. So, if whilst in ‘set’ mode,
the ‘+’ button is pressed 10 times (i.e. + 1,000 RPM), the new limit will be 7,000 RPM.

The Maximum Rev Limit is 20,000 RPM (4 cylinder), 12,000 RPM (6 cylinder), 10,000 RPM
(8 cylinder) and 20,000 RPM (2 cylinder).

The Minimum Rev Limit is 1,000 RPM for all number of cylinders.

SETTING HARD / SOFT CUT

The unit is equipped with either a ‘hard’ or ‘soft’ cut - it is set to ‘soft’ at the factory. On soft
cut, the unit will begin to gradually limit engine power 200 RPM earlier than the set limit.

To change the setting, switch the ignition to the ‘off’ position. Press the ‘-’ button and keep it
held down whilst turning on the ignition, but do not start the engine. LED 2 will light,
indicating that soft cut is set. Release the button. To change to hard cut, press the ‘+’ button
LED 1 will light. To change back to soft cut, press and release the ‘-’ button. To exit the
Hard/Soft mode, turn the ignition off or start the engine.
