Activate up to two camshafts independently on engines which use dual profile camshafts, specifically Nissan’s VVL/Honda VTEC
Camshafts profiles can be switched according to two 0-5v sensor signals and/or RPM.
CamSwitch 3 can also trigger any device which is switched on with a 12 volt source and which uses less than 3 amps.
Trigger up to two camshafts independently according to two sensors and RPM
CamSwitch3 Engine Bay Mounted Unit
CamSwitch3 Android App
Wiring Loom if Ordered
A minimum of one 0-5v sensor
Manual & App
-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
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.
1 x power 12-24 volts with 1 amp inline fuse (fuse not included)
2 x 5 volt sensor inputs
1 x 5 volt timing signal. 1,2,3 or 4 sparks per engine revolution
2 x 12 volt output with 5 amp inline fuse on positive (fuse not included). Permanent 12 volt to solenoid/motor, switch on negative side.
2 x 5 volt output. For external sensors eg you want to use a MAP sensor but engine does not have one. 0.5 amp current draw maximum per sensor.
The wiring diagram and instructions can be found in the user manual which can be downloaded in PDF
This video shows the process of setting up your cam switch points. The interface is from the CamSwitch1.
The CamSwitch3 interface is slightly different but the principles are the same
