I have a '97 Suzuki TL1000S with OEM fuel injection. From what I gather, it uses ignition pickups on the stator(crankshaft speed) to trigger spark and injector timing but also uses the Cam Position Sensor to orient it for no wasted spark or injector firing at a closed intake valve (power stroke).
Is this a common way of "orienting, indexing, letting the ECU know where the engine is in its cycle"?
Does microSquirt take all of this into account? I'm asking because if my assumptions are correct then I will try to rig a Cam Position Sensor on the bike I will be converting to FI.
Also, the small wheel that the Cam Position Sensor uses has springs on it and looks like the centrifugal advance wheel on many distributors I've seen over the years. Is this a common way to provide advance/retard?
Cam position sensor.

It looks like your cam position sensor may actually be a spark trigger for a non-computer controlled timing.
For Microsquirt, you can use a single cam sensor with no advance mechanism, and a toothed wheel on the crank / stator with all the teeth equally spaced. This is a pretty common trigger setup.

According to those in the know on another site, if the cam position sensor is unplugged while the bike is running it will continue to run but if shut off it will not restart. This is one of the first bikes Suzuki had fuel injection on, a 1997 TL1000S, so it may have had some quirks.
So basically if I wanna create a cam position sensor to use on a bike without one and using microSquirt, will I need to have two trigger points or just one? On on each cam or on just one cam This is a SOHC oddfire V-twin. It looks like I'd be able to mount the magnet on the cam sprocket and then mount a hall sensor in the housing that goes over the cam.
