INTRODUCTION

This data is stored in memory even after power is shut off, and can be played back any number of times.
• Any Auto Meter Shift-Lite™, or Quick-Lite™ Shift-Lite can be used with this tach. Up to four different shift points can be used to activate the Shift-Lite.
• When a Shift-Lite is used, Auto Meter’s unique Launch Lite™ feature gives a visual indication that the staging/launch
RPM is either AT, ABOVE or BELOW a user changeable set point.
• The number of ignition Pulses Per Revolution (PPR) of the engine can be set from .5 PPR to 6 PPR.
