Product Description
EDGE PRODUCTS 98653 EAS SOTF – SHIFT-ON-THE-FLY CONTROL FOR 2011–2016 LML DURAMAX
The EDGE PRODUCTS 98653 EAS SOTF (Shift-On-The-Fly) Accessory gives you on-screen control of your custom tunes on 2011–2016 Chevy Silverado and GMC Sierra 2500/3500 trucks equipped with the 6.6L LML Duramax diesel. Instead of drilling the dash for a rotary switch, you use your Edge Insight monitor to change tune levels while you drive for a clean, factory-style interior.
- Designed specifically for 2011–2016 GM 6.6L LML Duramax 2500/3500 trucks
- Integrates with Edge Insight CS2/CTS2/CTS3 for on-screen SOTF tune changes*
- Replaces traditional 5-position mechanical SOTF/DST switches
- Outputs 1–5V signals to select up to five custom tune levels**
- Duramax-specific harness connects at the ECM – no cutting or splicing required
*Edge Insight monitor required (sold separately).
**Requires custom tuning that supports voltage-based Shift-On-The-Fly (SOTF) or Driver-Selectable Tuning (DST).
FITMENT – EDGE 98653 EAS SOTF (LML DURAMAX)
- Engine: 6.6L LML Duramax V8 diesel
- Platform: GM HD trucks
- Vehicles: Chevrolet Silverado 2500HD/3500HD, GMC Sierra 2500HD/3500HD
- Model Years: 2011, 2012, 2013, 2014, 2015, 2016
- Drivetrain: 2WD & 4WD

This kit is aimed at LML Duramax owners using custom tuning that expects a 1–5V input for power level selection. It plugs into the ECM pin harness on the LML so you can keep the factory wiring intact while gaining smooth, electronic tune control through the Insight screen.
HOW THE EDGE PRODUCTS 98653 EAS SOTF WORKS
Many custom Duramax tuners use a voltage signal (1V, 2V, 3V, 4V, 5V) to pick between multiple tune files. Traditionally this is done with a physical rotary switch mounted in your dash. The 98653 EAS SOTF replaces that switch with your Edge Insight monitor.
- The EAS SOTF harness connects the Insight monitor to the ECM SOTF/DST pins on your LML Duramax.
- The Insight outputs one of five voltage steps (1–5V) that your custom tuning is set up to read.
- Your ECM interprets those voltages just like it would a mechanical SOTF knob.
- You select power levels right on the Insight screen instead of reaching for a separate switch.
Important: The 98653 is not a tuner by itself. It does not flash or add tunes to your truck. It simply gives you a cleaner, digital way to control existing voltage-based custom tunes using an Edge Insight monitor.
KEY FEATURES & BENEFITS
- LML-Specific Harness: Purpose-built for 2011–2016 6.6L LML Duramax with an ECM pin-harness connection—no cutting or splicing required.
- On-Screen Power Level Selection: Select tunes from the Insight CS2/CTS2/CTS3 display instead of using a separate dash switch.
- Cleaner Interior: No extra holes in the dash, no bulky rotary knob—just the factory look with more capability.
- Custom Tuning Friendly: Works with most EFI Live, EZ Lynk, and other voltage-based SOTF calibrations when properly configured.
- Plug-and-Play EAS Design: Built on Edge’s Expandable Accessory System so your wiring stays neat and modular.
WHAT’S INCLUDED
- Edge 98653 EAS Shift-On-The-Fly Accessory (LML-specific)
- Duramax ECM harness/interface wiring
- Installation instructions
Note: Edge Insight monitor and custom tuning are not included. You must already have, or plan to purchase, compatible custom tunes and a supported Insight monitor.

FAQ
Does the EDGE 98653 add horsepower or tuning by itself?
No. The 98653 EAS SOTF accessory does not contain any tuning files. It simply gives you a way to command different power levels for existing custom tunes using your Edge Insight monitor.
What monitors are compatible with the 98653 EAS SOTF?
The 98653 is intended for use with Edge Insight CS2, CTS2, and CTS3 monitors that support EAS accessories. Always confirm compatibility and make sure your monitor firmware is up to date before installation.
Will this work on a stock 2011–2016 LML Duramax without custom tuning?
No. Your truck needs custom tuning that is specifically configured for voltage-based Shift-On-The-Fly or Driver-Selectable Tuning. On a completely stock ECM, the SOTF accessory will not provide any benefit.
Do I still need a separate SOTF switch with this kit?
In most installations you do not. The purpose of the 98653 is to replace a mechanical SOTF/DST switch and let the Insight monitor handle tune selection electronically.
Is the EDGE 98653 emissions legal for on-road use?
Emissions compliance depends on the custom tunes you run and how the truck is configured. The accessory itself only provides a control signal, but many custom calibrations are intended for off-road or competition use. Always follow federal, state, and local emissions laws.
