Complete control of camshaft activation for Nissan VVL/Honda VTEC and any camshaft switching/solenoid that uses 12V for ON-OFF activation.
Activate up to two camshafts ie intake cam and exhaust cam independently
Activation based on up to two 5 volt sensor signals and/or RPM
Settings inputted via Bluetooth App
Cam Shaft Activation Example
Intake cam activation
At 50% MAP signal and 5000rpm and 50% MAF signal
and at the same time
exhaust cam activation based on
60% MAP signal and 5200RPM and 70% MAF signal
Deactivation of both cams occurs simultaneously according to Intake cam parameters.
Example (using the above data)
When MAP signal reaches 45% (ie 5% less than the MAP/sensor 1 trigger value), BOTH cams will be deactivated together.
Adjustable delay for switch off.
Choose between 0 & 5 seconds. If you have periods of part throttle but you want to keep the cams activated for next application of the throttle.
Any 0-5v crank or cam signal can be used for RPM. CamSwitch App allows the user to calibrate the RPM easily
CamSwitch App includes seperate menu to test cam activation when engine is not running.
External Sensor Power
Power an external 5v sensor with the CamSwitch eg use it to power a MAP sensor for cars which do not have one from the factory.
Customise the name of the Intake and Exhaust cams if you are using CamSwitch to trigger things other than 12v camshaft solenoids eg intercooler sprayer, exhaust valve
Customise the bar colours which indicate sensor percentage
Customise the colour of the display which shows when cam/solenoid is activated.
Bluetooth Cross Checking
We see many Bluetooth products which simply send the signal to the device and assume the device has received the signal solely based on the fact that the two devices are connected. In our experience this can be unreliable and can lead to large differences between anticipated setting.
The CamSwitch App will send the signal to the main unit, it will then wait for the unit to reply with the new setting BEFORE displaying the new setting on the CamSwitch App. This way you know that the setting displayed on the CamSwitch App is real. The downside of this cross checking is a display that is slightly slower to update but we believe accuracy is worth the tradeoff.
Max current for main control unit 1 amp
Max current for each cam/solenoid activation channel 3 amps
Max input voltage for main control unit 15 volts
Max input voltage for cam/solenoid activation 24 volts
Product is not water proof. It should be mounted away from obvious sources of heat and moisture with connector facing down. Do not enclose in a plastic bag as it can trap moisture.
-Trigger up to two 12v solenoids
(Maximum amp draw 3 amp per solenoid)
-Trigger each solenoid independently according to MAP and/or RPM and/or MAF (or use any two 5 volt sensors you wish)
-On board power for one 5 volt sensor (if you need an extra sensor, eg MAP on normally aspirated car)
-Fine tune RPM signal
-Customise the name of the sensors
-Customise the delay for the cams closing eg when trigger conditions are no longer met, how long should system wait before closing solenoids (eg to keep cams/solenoids on between gearchanges)
-Test solenoid activation without engine running
-Visual indication of cam activation through Android App (primarily for diagnostic purposes)
-Visual indication when thresholds met through Android App (primarily for diagnostic purposes)
12 volt power supply
5v timing sensor signal, Hall (for triggering according to RPM)
Up to two 5 volt sensors
Android mobile phone with Bluetooth
CamSwitch Android App
How it Works
All settings are done through the CamSwitch Android application
Trigger points are set by selecting a percentage of 5 volts (so product is compatible with 5 volt sensors)
RPM trigger points is set use 200 rpm increments
An example. You want to trigger the intake cam with minimum 50% throttle (MAP) at a minimum of 4000 rpm with a minimum of 50% of maximum flow according to the MAF sensor.
CamSwitch will first look at the MAP signal. When it reaches 50%..
CamSwitch will look at RPM to set if that meets the minimum condition. When RPM also reaches its minimum threshold…
CamSwitch will look at the MAF sensor & when this reaches the minimum threshold, the intake cam solenoid will be activated
The exhaust cam will follow the same procedure.
When SENSOR 1 falls below the minimum threshold BOTH solenoids will be turned of together. ONLY when sensor 1 drop below the minimum threshold will BOTH solenoids be deactivated.
What is Included
The CamSwitch control unit
CamSwitch Android App
System works as SENSOR 1 and SENSOR 2. You can use whichever sensor you want as each sensor eg SENSOR 1 can be a MAF sensor or a MAP sensor or any other 5v sensor you wish.
You can customise the name of each sensor in the App
When connected to the App, the more sensor readings and the more information you want displayed on your Android device, the slower the response of the unit. This is limit by the Bluetooth connection speed.
In normal driving we recommend not using the App or only using the App to display sensor readings and NOT trigger settings. Due to the amount of settings available, they will slow the response of the unit. CamSwitch is not a substitute for dedicated gauges
