Longacre AccuTech SMi Stepper Motor Memory Tach White

Stepper Motor Racing Memory Tach


The next generation in instrumentation

SMi stepper motor gauges use a small electronic motor that turns a tiny fraction of a rotation to drive the pointer. It's electronically controlled and is much more precise than traditional mechanical instruments.  Many professional race teams - NASCAR, etc. – are switching to this style of gauge for the improved accuracy.  Approved for use by IMCA.

TWO-STAGE High RPM Warning Light

First warning can be set for just over your normal maximum RPM. The LED lights up to give you a heads-up.  The second warning can be set at your redline, where the LED begins flashing.  You get a warning of too many revs before you blow your engine.  Can also be used as a two-stage shift light.

Choose white or black dial face.

Available with black anodized aluminum panel featuring clean, cool graphics (choose option above).



  • Maximum RPM recall, ,just push the "Recall" button.
  • LED back light shows through the dial face and the pointer is LED illuminated to make this the easiest-to-read (sharpest looking) tach available.
  • Stepper motor precision tach at an affordable price


NOTE: This electronic tachometer is not intended to be waterproof. Cover the tach if the car interior is to be washed down.
