RPM Activated Switch – CamSwitch3

225 145

This RPM Activated Switch can trigger up to two 12 volt circuits independently.

Each circuit can also use up to two 0-5 volt analog inputs as well as RPM, if need to control the circuits with more precision.

How Is it Programmed?

The CamSwitch3 RPM window switch is mounted in the engine bay and is programmed via Bluetooth using the CamSwitch3 Android App

General Usage Examples

  • Camshaft activation eg VVL/VTEC
  • Fan activation
  • LED activation
  • Additional fuel pump activation (with external relay, not included)
  • Active aero parts eg diffusers, spoliers

NOTE: The CamSwitch 3 rpm activated switch can trigger circuits with current requirements less than 3 amps directly.

For circuits requiring more current, external relays must be used. These relays are not included.

**Not suitable for use with Nitrous**

Features

Trigger up to two 12 volt circuits independently using up to two sensors and/or RPM

Customise the activation of 12 volt circuits according any 0-5 volt sensor input. For example:

  • Circuit activation according to engine load, steering angle and RPM.
  • Switch a 12 volt circuit based on engine load, RPM and coolant temperature
  • Switch a 12 volt circuit according to engine load, RPM and intake air temperature

Benefits

  • Optimise performance of 12 volt circuits by activating the circuit only when it is required
  • Optimise engine performance by only activating 12 volt circuits based on user specified engine operating conditions eg activating CO2 spray on an intercooler when intake temps and engine load above user programmed thresholds.

Note: the app will only work when connected to the unit. Check the video below to see how the app works.


Specific Example Usage

Camshaft Activation Conditions

-Camshaft 1 activation at 30% MAP sensor signal & over 5000 rpm & coolant temp sensor over 70% signal

-Camshaft 2 activation at 30% MAP sensor signal & over 5500 rpm & coolant temp sensor over 70% signal

Camshaft Deactivation

Deactivation for both camshafts will happen at the same time one second after MAP sensor signal drops below 30% MAP or RPM drops below 5000rpm.


Wiring

Inputs

1 x power 12-24 volts with 1 amp inline fuse (fuse not included) to battery positive

2 x 5 volt sensor inputs

1 x 5-30 volt switched timing signal (eg coil on plug activation signal). 0.5 or 1 spark signals per engine revolution

Output

2 x 12 volt switched ground signal output. (3 amp per circuit max)

2 x 5 volt output (0.5 amp max). For external sensor power eg you want to use a MAP sensor but engine does not have one.

FAQ

FAQ

Q. Do I have to trigger two camshafts?

A. No. If you just need to trigger one camshaft, just connect one camshaft!

Q. Can I use it to activate other things?

A. Sure but you need to familiarise yourself with the way the relays are activated and how they are deactivated. From an electrical point of view the maximum current draw for the relays in 3 amps per relay, 5 amps total. Download the instruction manual for more information.

Q. Do I need to connect my phone to the Cam Switch 3 every time I use the Cam Switch 3?

A. Absolutely not! Connecting to your phone is only for adjusting the trigger settings and to troubleshoot.

99.999% of the time the Cam Switch 3 is a fit and forget device. Wire it up, tune your engine to find the optimum settings and your done, no need to do anything with it until you want to change your settings.

Q. I only need to trigger the camshaft using RPM and one 5 volt sensor signal. Is that possible?

A. Absolutely. Set the trigger threshold for Sensor 2 to zero. If the sensor value for Sensor 2 is bouncing around unacceptably connect the Sensor 1 signal to Sensor 1 and Sensor 2 input on the Cam Switch unit.
