APPLICATION #4 ()
Convert an 8000ppm signal from an aftermarket signal generator to a 4000ppm or 2000ppm to run
an OEM cruise control or fuel injection computer.
Either two wire or three wire sensors can be recalibrated with this unit. Two wire sensors will
typically have one wire as a ground and the other as the signal. Three wire sensors will have an
additional power wire. You must first determine which wire is the signal. The signal wire will be
tapped into so the SGI-5 E can read it. The sensor signal wire will go to the SIGNAL IN terminal.
Connect the POWER terminal to a 12-volt accessory wire and connect the GROUND terminal to a
good ground location. If using a Jeep or Chrysler 3-wire, 8000ppm generator, the Sensor Power wire
can be used to feed power to the POWER terminal If nothing else is connected to a two wire sensor,
then connect one wire to the GROUND terminal also. The output connections will depend on your
particular application. Here are some typical examples:
OUT3, 4000ppm AC:
OUT4, 4000ppm oc:
OUT5, 2000ppm oc:
APPLICATION #5 ()
Convert a 16000ppm signal from a Hall Effect signal generator to 8000ppm, 4000ppm, or 2000ppm
to run a cruise control or fuel injection computer.
The Hall Effect sensor will have three wires. The white wire is the signal. The signal wire will
be tapped into so the SGI-5 can read it. The sensor signal wire will go to the SIGNAL IN terminal.
Connect the POWER terminal to a 12-volt accessory wire and connect the GROUND terminal to a
good ground location. The output connections will depend on your particular application. The CAL
ratio should be set to 0.500 as a starting point. Here are some typical examples:
OUT1, 8000ppm AC:
OUT3, 4000ppm AC:
OUT4, 4000ppm oc:
OUT5, 2000ppm oc:
