Since 1957, AutoMeter has set the standard in performance, accuracy and durability with their legendary Tachometers. Built for a lifetime of service under the harshest conditions, this is the no compromise tach for no compromise builds. Record up to 80 seconds of engine RPM data and playback at slow motion speeds to analyze vehicle and driver performance following a run. Identify key performance data such as burnout, launch RPM, tire spin, gear changes and engine speed through the traps to fine tune your setup and trip the win lights.
