5.10 Cam1 Sensor
If an engine is to control the injectors sequentially or ignition coil-per-plug, it needs information about
what part of the engine cycle it is in (there are two crank revolutions per engine cycle for a 4 stroke
engine). The cam sensor provides this information (as there is only one cam revolution per engine
cycle for a 4 stroke engine).
Cam1 Lo Gain Above
Some VR cam sensors give too high an output at high engine speeds.
This feature allows the sensitivity of the ECU to be switched to lower
above the set engine speed to allow for this. Typically 1500rpm.
Cam1 Hi Gain Below
High channel sensitivity when below this value. Should be set below the
on value (hysteresis). Logic level sensors (hall effect) set to 0
Cam1 Rising Edge
rising edge of the crank signal is used as the significant edge if ON.
Typically OFF
Cam1 Falling Edge
falling edge of the crank signal is used as the significant edge if ON.
Typically ON
The cam input can be from either a MVR or Hall sensor. Jumpers on the board must be set to allow
for these two sensor types.
