Universal Tachometer Signal Interface
The NEW SGI-8E Tachometer Interface Unit is designed to allow a factory tachometer to function accurately after performing an engine swap to an engine with a different number of cylinders or tach signal. If you are swapping out a V-6 for a V-8 and you need to recalibrate the tach signal from the V-8 to make it read accurately on the factory V-6 tachometer, the SGI-8 will do the job. With adjustability up to 16x, the SGI-8 is capable of recalibrating tachometer signals for nearly any engine swap combination. All setup, calibration and diagnostic functions are handled with the use of a built-in 3-digit display and integrated pushbutton switches.
