EDGE PRODUCTS 98652 EAS SOTF 2010-2018 DODGE/RAM 2500/3500 6.7L CUMMINS DIESEL

The EDGE PRODUCTS 98652 EAS Shift-On-The-Fly (SOTF) Accessory gives your 2010–2018 Dodge/Ram 2500/3500 6.7L Cummins the ability to change custom tune power levels directly from an Edge Insight monitor. Instead of drilling the dash for a manual switch, this plug-and-play EAS module uses the Insight CS2/CTS2/CTS3 display to send 1–5V signals to your custom tuner so you can move between tune levels on the screen while you drive.

• True shift-on-the-fly control for custom tuning on 2010–2018 6.7L Cummins trucks when paired with compatible SOTF/DST tunes.
• Uses the Insight monitor as your switch – no more drilling holes or mounting separate rotary knobs in the dash.
• Integrates with popular custom tuning platforms that use 1–5V inputs to select between multiple power levels (5-position style).
• Clean, OE-style install using factory-style connectors and Edge’s Expandable Accessory System (EAS) architecture.
• Perfect companion to Insight CS2/CTS2/CTS3 on a tuned 6.7L Cummins tow rig, street truck, or work truck.

How the EDGE 98652 EAS SOTF Works

The 98652 module plugs into your Edge EAS network and ties into the truck’s harness at the appropriate location. When your ECM has been flashed with SOTF/DST-capable custom tunes, each power level is selected by a specific voltage signal. The EAS SOTF simply replaces the physical switch and lets the Insight screen generate those 1V–5V signals, telling the ECM which tune to use:

• Voltage steps typically represent up to five custom tunes (for example: stock, tow, street, performance, race).
• You select the tune level on the Insight display instead of turning a manual knob.
• No extra holes, no clunky toggle switches – just factory-style wiring and a clean, digital interface.

Note: This accessory does not create tunes or function as a downloader on its own. It replaces the physical SOTF/DST switch for trucks already set up with compatible custom tuning.

Ideal Use Cases

• Daily driver: Keep it mild in bad weather or around town, then bump to a more aggressive tune on the highway.
• Performance builds: Pair with bigger turbo, injectors, and built transmission tunes for track or sled-pull setups while keeping clean control from the screen.

FAQ – EDGE PRODUCTS 98652 EAS SOTF

Does the EDGE 98652 add power to my 6.7L Cummins by itself?

No. The 98652 EAS SOTF accessory does not create or flash tunes. It simply replaces a physical SOTF/DST switch and lets your Edge Insight monitor select between existing custom tunes that are already loaded in the ECM.

Which monitors work with this SOTF accessory?

This kit is designed to be used with Edge Insight CS2, CTS2, and CTS3 monitors that are equipped with the EAS harness. If you don’t already have an EAS cable, pair 98652 with the EDGE 98602 EAS Starter Kit and an Insight monitor from CPP Diesel.

Will EDGE 98652 work on all 2010–2018 Ram 6.7L Cummins trucks?

Fitment is for 2010–2018 Dodge/Ram 2500/3500 6.7L Cummins trucks that are running compatible custom tuning designed for voltage-based SOTF/DST switching. It will not convert a stock truck into a tune-on-the-fly setup without the proper tunes.

Do I still need gauges if I use the Insight and SOTF?

The Insight CTS3 (or CS2/CTS2) is effectively your gauge package. With EAS sensors for EGT, boost, fuel pressure, and trans temp, you have everything you’d get from multiple analog gauges – plus data logging – in one clean screen. We strongly recommend EGT and trans temp monitoring on any truck running multiple power levels.

Is this kit emissions compliant?

The 98652 is an accessory that controls existing custom tunes and does not directly alter emissions equipment. Always verify that your tuning is appropriate for your truck’s emissions configuration and local regulations.
