Edge EAS Shift-On-The-Fly Module for 2011-2016 GM 6.6L LML Duramax Custom Tunes - 98653

The Edge EAS Shift-On-The-Fly module 98653 lets a custom-tuned 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD 6.6L LML Duramax change tune levels from the Edge Insight CTS3 touchscreen instead of a switch mounted in the dash. It connects where the conventional SOTF or driver-selectable-tuning switch would and steps the signal through 1, 2, 3, 4 and 5 volts, which is how most custom tuning software selects power levels.

It does not include or load any tunes. The truck must already be running custom tuning from a third-party tuner with a voltage-switch input; this module replaces the switch and shows the current level on screen.

What it does

• Change tune levels with a tap on the CTS3 power level screen
• Current level displayed on the monitor
• Steps the level signal through 1 to 5 volts
• Plug-and-play into the EAS chain; no hole drilled in the dash

Installation and limitations

Connect the module where the conventional SOTF switch would be wired or plugged in, connect it to the EAS chain on the CTS3, then flash the tune that enables the SOTF or DST function. The Duramax module connects at the ECM and must be wired as instructed with ground and signal in the correct pins; it controls only tune levels switched through those pins. Custom tunes are created by third-party tuners and are not affiliated with Edge.

Frequently asked questions

Does this come with tunes?

No. It only switches levels on a truck that is already custom tuned with a voltage-switch input. Tunes come from your tuner.

Do I need the EAS starter cable?

Yes, if this is your first EAS accessory. It connects the EAS chain to the monitor OBD-II cable.

Will it work with a CTS2?

The current SOTF modules are designed for the Insight CTS3. Check with us before ordering for another display.

Can I still use my dash switch?

The module replaces the switch. You control levels from the monitor screen instead.
