It uses the Digifant computer, without it the engine would run like crap as
NG has a lower octane than gasoline so the timing changes between the two
fuels.  Very very simple kit.  Essentially when you flick the switch in the
cab the gasoline pump turns off and the natural gas regulator introduces
natural gas upstream of the air flow sensor.  The mixture of NG and air
then gets sucked into the cylinders and ignition takes place.  There is
compensation for load via a small computer that attaches to the NG
regulator.  This computer gets signals from the distributor and somehow
know the load state from that.
