OMRLC Rev Limiter Clubman Instruction Manual

OMRLC Rev Limiter Clubman

Product Information: REV CLUBMAN OMRLC

The REV CLUBMAN OMRLC is a rev limiter suitable for most 4-stroke petrol engines and most ignition types. It is designed to limit engine revs and not a vehicle’s road speed. The unit is not suitable for capacitor discharge (CDi) systems or positive earth vehicles. It comes with attached color-coded wires and supplied cable connectors.

Features:

• High-quality shift light recommended
• Two LED indicators
• Two buttons for setting functions
• Soft or hard cut options

Installation:

1. Ensure the ignition is turned off before starting installation.

2. Remove the backing from the adhesive pad on the back of the unit and mount it to a clean, flat, grease-free surface.

3. Keep the unit away from hot or exposed areas and ensure that the unit and all wires are kept as far as possible from the HT parts of the ignition system.

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

   • Violet wire: connect to the coil negative (-) terminal.
   • Red wire: connect to the coil positive (+) terminal. If this is not easily accessible, this wire can be connected to any positive feed that is switched by the ignition switch.
   • Black wire: connect to any good electrical connection on the car bodywork. It is essential that a good quality connection is made. Keep wires clear of hot or rotating parts.

Usage:

1. 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.
   • To change the cylinder setting, press and release the +’ button (or-‘ button).
   • The number of cylinders will go to the next (or previous) setting.
   • To exit from Set Cylinder mode, turn the ignition off or start the engine.
   •  Changing the number of cylinders automatically resets the rev limit to 6,000 RPM.
2. Setting Hard/Soft Cut:
   • The unit is equipped with either a hard’ orsoft’ cut – it is set to `soft’ at the factory.
   • 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. Release the button.
   • To change back to soft cut, press and release the `-‘ button.

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 color coded wires and the supplied cable connectors.

• VIOLET 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. It is essential that a good quality connection is made.
  Keep wires clear of hot or rotating parts.

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:-

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.

To change the cylinder setting, press and release the ‘+’ button (or ‘-’ button). The number of cylinders will go to the next (or previous) setting. To exit from Set Cylinder mode, turn the ignition off or start the engine.

Changing the number of cylinders automatically Resets the rev limit to 6,000 RPM

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. Release the button. 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.

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 both buttons. Both LEDs will flash briefly.

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.

RESETTING THE REV LIMIT – in order to provide a reference point, you may wish to reset the unit back to 6,000 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. The unit will automatically enter into the ‘set’ mode
(see above) as you let go of the buttons.
