Details

Recording engine and driveshaft RPM enables you to analyze torque converter and clutch performance, tire slippage or shake, shift points, and more. Pause playback on the LED to directly compare engine, driveshaft, and engine-to-drive ratio. Use the Tach Facts software to further analyze this data to 1/100th of a second.

The mini shift light has four shift points for optimum control. You can dial in on the anticipated RPM rise for each gear, increasing consistency and guarding against unnecessary RPM spikes.

Short shift protection means the tach knows to activate the next shift point if you short shift.

A clear 100 samples per second provide .01 second accuracy on the LED during playback.

The recording settings are Pre-Race/Burnout with Intelligence, Unlimited Pre-Race, and 20-Second Burnout and Run. Triggered by an adjustable RPM threshold, burnout recordings stop when RPM go below the threshold. Post-burnout data is automatically erased until 2 seconds before launch.

The Peak/Valley Mode freezes playback at the highest and lowest points of each gear. The time difference between the peak and valley shows whether clutch or transmission slippage is a problem.

Download data to a laptop or PC, or view each pass in real time on the tachometer.

Tach Facts software allows for an in-depth engine, driveshaft, or engine-to-drive ratio analysis.
