Product Description
EDGE PRODUCTS 98651 EAS SHIFT-ON-THE-FLY ACCESSORY – 2015–2019 FORD 6.7L POWER STROKE
The EDGE PRODUCTS 98651 EAS SHIFT-ON-THE-FLY (SOTF) ACCESSORY gives you clean, on-screen control of your custom tunes on 2015–2019 Ford F-250/F-350 6.7L Power Stroke trucks. Instead of drilling a hole in your dash for a rotary SOTF switch, this EAS module lets your Edge Insight CS2/CTS2/CTS3 output the same 1–5 volt signals that your custom tuner uses for multiple power levels—so you can change tunes right from the monitor.
- Designed specifically for 2015–2019 Ford F-250/F-350 6.7L Power Stroke diesel
- Integrates with Edge Insight CS2/CTS2/CTS3 for on-screen tune selection*
- Replaces traditional 5-position SOTF / DST dash switches
- Outputs 1–5V signals to match custom-tuning SOTF voltage tables**
- Clean, plug-and-play EAS install – no dash cutting or extra holes
*Insight monitor required (sold separately).
**Requires custom tuning that supports voltage-based SOTF/DST switching.
FITMENT – EDGE 98651 EAS SOTF
- Engine: 6.7L Power Stroke V8 diesel
- Vehicles: Ford F-250 & F-350 Super Duty
- Model Years: 2015, 2016, 2017, 2018, 2019
- Drivetrain: 2WD & 4WD
- Use Case: Trucks running compatible custom SOTF/DST tuning (EFI Live, EZ Lynk, etc.)
On Power Stroke platforms, the EAS SOTF accessory interfaces with the factory fuel temperature sensor circuit as specified by your tuner. It mimics a traditional SOTF or DST switch, but moves control to your Edge Insight screen instead of a physical knob.
HOW THE EDGE 98651 EAS SHIFT-ON-THE-FLY WORKS
When installed, the 98651 lets your Insight monitor send one of five voltage levels (1V, 2V, 3V, 4V, 5V) into the same input your custom tune expects for SOTF or DST. Your calibrator ties each voltage to a different power level—tow, street, performance, race, etc.—so you can cycle tunes in real time.
- Install the EAS SOTF accessory inline with your Edge Insight harness.
- Connect the output into the circuit your custom tune uses for SOTF/DST switching (often via the fuel temp sensor circuit).
- Load custom tunes that support voltage-based SOTF/DST on your 6.7L Power Stroke.
- Select power levels on the Insight screen while driving, towing, or dyno testing.
Important: The 98651 does not add tuning by itself. It does not turn an Insight into a programmer. It only provides a digital replacement for a mechanical SOTF/DST switch so your existing custom tunes can be controlled from the monitor.
KEY FEATURES & BENEFITS
- On-screen tune control: Change SOTF power levels from your Insight CS2/CTS2/CTS3 instead of a dash-mounted knob.
- No extra holes in the interior: Avoid drilling and keep your Super Duty’s dash looking OEM.
- Built for custom-tuned 6.7L Power Stroke trucks: Ideal where your tuner uses a 1–5V SOTF/DST input.
- Plug-and-play EAS integration: Uses Edge’s Expandable Accessory System for a clean wiring layout.
- Backed by Edge: Quality harnessing, sealed connectors, and a limited manufacturer warranty.

INSTALLATION NOTES
- Requires Edge Insight CS2/CTS2/CTS3 monitor with EAS capability.
- Requires custom tuning configured for 1–5V SOTF/DST input on 2015–2019 6.7L Power Stroke.
- Route wiring away from heat sources, sharp edges, and moving components.
- Verify correct tune selection and voltages before towing or wide-open-throttle passes.
FAQ
Does EDGE PRODUCTS 98651 tune my 6.7L Power Stroke by itself?
No. The 98651 is not a programmer or downloader. It only provides a digital replacement for a mechanical Shift-On-The-Fly or DST switch so that can be changed using the Edge Insight monitor.
Which Edge monitors work with the 98651 EAS SOTF accessory?
The 98651 is designed for use with Edge Insight CS2, CTS2, and CTS3 monitors that support EAS accessories. Always verify your monitor part number and firmware with Edge if you’re unsure.
Will this work on a stock (untuned) 2015–2019 6.7L Power Stroke?
No. Stock Ford calibrations do not support voltage-based SOTF switching. You must have custom tunes that are written to use a 1–5V input for multiple power levels. Without compatible tuning, the 98651 will not change power levels.
Do I still need a separate SOTF knob or rotary switch?
In most cases, no. The 98651 is designed to replace a mechanical SOTF/DST switch by sending the same voltage steps through the factory circuit, controlled through your Insight monitor instead of a dash-mounted knob.
Is the 98651 emissions compliant for on-road use?
Emissions compliance depends on your custom tuning and how the vehicle is used. The 98651 itself is an accessory, but many custom tunes are for competition or off-road use only. Always follow your tuner’s guidance and comply with all federal, state, and local laws.
