SGI-5 E
UNIVERSAL SIGNAL INTERFACE UNIT
The Dakota Digital SGI-5 E is designed to recalibrate a speedometer signal or correct
sinewave(AC)/squarewave(‘oc’) signal incompatibilities. Here are some typical applications:
1. Recalibrate a high speed (32,000ppm
– 250,000ppm) signal for an OEM speedometer.
Do not
use this unit to adjust a signal going to an anti-lock braking system.
2. Recalibrate a low speed (32,000ppm
– 4,000ppm) signal for an OEM or aftermarket speedometer
or fuel injection computer.
3. Convert a high-speed signal found on newer GM transmissions down to a low speed signal to run
a speedometer, cruise control, or fuel injection computer.
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.
5. Convert a 16000ppm signal from a VDO Hall Effect signal generator to an 8000ppm, 4000ppm, or
2000ppm to run a cruise control or fuel injection computer.
6. Convert a 4000ppm signal from an OEM transmission speed sensor or ECM output to an
8000ppm signal for an aftermarket speedometer.
7. Convert an 8000ppm or 16000 ppm signal up to a high-speed 128,000ppm signal for a newer fuel
injection computer.
