Product Review

The NEW SGI-8E Tachometer Interface Unit is designed to allow a factory and many aftermarket tachometers to function accurately after installing an engine with a different number of cylinders or tach signal. For example, if you are swapping out a V-6 for a V-8 and you need to recalibrate the tach signal for the 6 cylinder tachometer, the SGI-8E will handle that!

The SGI-8E is capable of recalibrating tachometer signals from 1 to 16 cylinder applications and anything in between!

All setup, calibration and diagnostic functions are handled with the built-in 3-digit LED display and integrated pushbutton switches for a user friendly installation.

Unit measures 4" x 2" x 1" and is designed to be mounted inside a vehicle.

Product not compatible with most '86 to current European or '96 to current Jeep tachometers.
