If you’re running custom tunes on your 2011-2016 Duramax, the Edge 98653 EAS Shift On The Fly Accessory is the clean, modern solution you’ve been waiting for. Instead of reaching for an old-school rotary switch and drilling into your dash, this system connects directly through your Edge CTS2 or CS2 Insight monitor for seamless tune switching. You get the power to flip between tuning levels with just a tap on the screen or a quick press of a button. That means no more guesswork, no extra switches cluttering your interior, and no permanent modifications to your truck. Whether you’re adjusting for better fuel economy on the highway or dialing up more power for towing, this setup makes it simple and fast. It pairs with the Edge EAS Starter Kit (98620), which most users already have, making installation even easier. Best of all, it integrates smoothly into your existing system so you can focus on driving, not fiddling with wires or knobs. If you’re serious about custom tuning but want to keep your interior clean and factory-looking, this is the way to go.

Smart Integration That Connects Directly To Your ECM

The Edge 98653 EAS SOTF Accessory is built for Duramax owners who want reliable, on-the-fly tune control without the hassle of traditional wiring. Designed specifically for 2011-2016 GM Silverado and Sierra 2500HD and 3500HD trucks with the 6.6L LML Duramax engine, this accessory connects to your ECM pin harness using a 5-volt input signal, with voltage variations between 1 to 5 volts. This is the standard method most custom tuning platforms like EFI Live and EZ LYNK use to recognize power level changes. Once installed, it works directly through your Edge Insight CS2 or CTS2 monitor, allowing tune changes right from the screen interface. That means no splicing, no dash drilling, and no need for bulky switches. This accessory is part of the Edge EAS (Expandable Accessory System) lineup, ensuring plug-and-play compatibility when used with the EAS Starter Kit. It's a smart addition for any tuned LML Duramax looking for precision and clean integration without compromising factory aesthetics or system reliability.
