Fuel Flow Rate on CAN channels

Each cylinder has two fuel injectors.

The injectors alternate injecting on alternate piston strokes.

One injector is controlled by each lane A and B.

There is NO actual flow meter.

The ECU calculates the equivalent flow rate based on the engine rpm and the pulse width duration that the injectors are firing at.

Each lane reports the amount of fuel it is delivering.  ~50% from A and the other 50% from B.

If one lane goes down, the other lane takes over on every cycle.

At that point, the bad lane stops reporting and the good lane's fuel rate will double as it is now operating 100%.

The fuel flow is sent on the can bus in the form of pulse counts equivalent to a mechanical paddlewheel type fuel flow sender.

The K factor is typically 3500 pulses per gallon.
