Control your Trac-Pac(TM) Shift Light from Fast Lane Innovations with this companion app!

This device acts as a progressive shift light and RPM data logger to help you dial in consistency and diagnose issues like wheelspin, valve float, and determine your actual shift points.

Built-in analyzer function scans your log, determines when gear changes occurred, and calculates stats for each gear such as shift RPM, engine acceleration throughout the gear, shift time, time in gear, and more. This makes it easy to track performance improvements.

Set the performance optimizer to indicate your RPM and shift points that you set with red, yellow, and green progressive indicator lights.

Play back logs real-time so you can get a better understanding of your driving and the vehicle's behavior.

If you connect to your instrument lights, the brightness of the nameplate and gauges will dim when the headlights are turned on, and you can set how much dimmer the lights should be. The lights will dim further if you decrease the brightness of your instrument cluster as well!

WARNING: Do not watch your mobile device or the lights while you are driving! You can log your data while your drive and view it later when you're not moving. Distracted driving can result in serous injury or death to yourself and others.
