Edge's all-new EAS Shift-On-The-Fly (SOTF) allows you to change custom tunes* on the fly utilizing the Insight CS2 or CTS2. Change tunes right on the screen! Many companies use a voltage signal to change between their 5 tune levels, when tuned with custom tuning software. Instead of drilling a hole in the dash, add the EAS SOTF accessory to an Insight monitor to control custom tunes* while driving down the road.
Here is how it works:

Here is how it works:
1. The EAS Shift-on-the-fly accessory, connected to your Insight CTS2, will control your tune levels for vehicles requiring a switch to control the power levels.2. Switching occurs by changing voltages between 1v, 2v, 3v, 4v, 5v. Most custom-tuned vehicles run within these parameters.3. Wire or plug the switch in just as you would your normal Shift-On-The-Fly (SOTF) or Driver-Selectable-Tuning (DST) switch. Then, flash the tune into your vehicle that enables the SOTF/DST functions.4. Enjoy changing your power levels right through the Insight CS2 or CTS2 screen!
Note:
a. The Power Stroke EAS accessory plugs into the Fuel Temp Sensors. Onlycontrols tuninglevels that changevoltageresistance through that sensor.
