from what i see stan made a laser distributor.. it uses infrared light to detect the cycles the distributor rotor is doing.. it is runnig on a frequency of around 10 khz which gives real time response in acceleration the signal the distributor is putting off resembles alternating current (high ans low logic states) that signal is creating its gate duty cycle. for the analog and frequency circuits. the frequency pulse 10khz is determind when finding waters resonance. the scanning circuit searches for voltage spikes(resonance) and relays it to the frequency gen to lock onto....... the gas managment is set to control analogs output to vic.. to override gas production if max pressure is reached..
KISS
the laser distributor simply sends a signal to the solenoid for each water line to the injectors so they fire at the right timing for each piston cycle
thats why he used the distributor rotor and not a sensor on the crankshaft because the distributor is set up to turn 1:2 ratio with the crank
4 cycle engine, clue... sparkplug firing matches cycles for injection !
dont over think this stuff...
