Take control of what your dash doesn’t show with faster monitoring, useful maintenance tools and application-specific tuning options for trucks that tow, work and travel
OGDEN, Utah (Oct. 22, 2026) – Edge, the truck and diesel tuning brand helping drivers improve capability, control and confidence through performance technology, today announced the all-new CTS4, the next generation of its popular CTS platform. Designed to give truck owners a faster, clearer and more intuitive connection to their vehicles, CTS4 combines significantly upgraded hardware with a larger display, smoother live data, new maintenance tools and expanded monitoring and tuning capabilities.
Rather than simply adding processing power, Edge engineered CTS4 to make the entire user experience faster and more responsive. The upgraded processor and four times the memory capacity of the previous CTS3 allow CTS4 to respond more quickly to inputs, load information faster and deliver a smoother experience when navigating between gauges, menus and vehicle data.
A new 5.5-inch display provides 21% more viewing area, making critical vehicle information easier to see at a glance. Live data now refreshes at 60 frames per second, delivering up to six times smoother data visualization than CTS3 benchmarks. The result is fluid, easy-to-follow information that helps truck owners quickly understand what is happening with their vehicle while towing, hauling, commuting or pushing performance.
“CTS has always been about giving drivers access to the vehicle information their factory dash leaves out, and CTS4 takes that experience to an entirely new level,” said Zach Hill, business unit leader, Edge Products. “We focused on the things our customers interact with every time they get behind the wheel: speed, visibility, live data and ease of use while creating a platform that can support everything from straightforward vehicle monitoring to custom tuning and integrated power control. CTS4 is faster, smarter and built around how truck owners actually use their vehicles.”
One of the most requested features from previous-generation CTS devices, Maintenance Minder, returns with CTS4. Particularly useful for owners of older trucks that may lack sophisticated factory maintenance reminders, Maintenance Minder lets them track key service intervals directly via their CTS4.
Peak Value Recall gives truck owners another level of insight by allowing them to review the highest values recorded for supported monitored parameters. Instead of constantly watching the display, drivers can reference peak readings after a drive, towing or other demanding operating condition to better understand how their vehicle performed.
CTS4 also features an approximately three-second monitor-screen startup, helping truck owners get the information they want shortly after starting their vehicle. A guided tutorial simplifies initial setup and helps new users quickly become familiar with the platform.
Dual USB-C connections and a direct RCA input simplify installation and accessory integration, while new rear quick-action buttons provide convenient access to frequently used functions without navigating through multiple menus.
The CTS4 family is offered in four configurations, allowing enthusiasts to choose the level of monitoring, tuning and power control that fits how they use their truck.
- Insight CTS4 is designed for enthusiasts who want to know more about what is happening with their vehicle without changing its factory performance calibration. Real-time monitoring gives drivers visibility into supported parameters their factory gauges may not display, helping them keep a closer eye on vehicle operation while towing, hauling, traveling in an RV, working or simply driving every day. Built-in diagnostics also make it easier to identify and clear supported trouble codes without reaching for a separate scan tool.
- Insight+ CTS4 adds native PowerCal custom-tuning capability to the Insight platform. For enthusiasts working with a compatible professional tuner, custom calibrations can be loaded and managed through the CTS4, creating a convenient plug-and-play interface for custom tuning and vehicle monitoring from a single device. Custom tuning can allow a qualified tuner to tailor a supported vehicle’s performance to specific modifications, driving preferences or intended uses.
- Evolution CTS4 combines the complete monitoring experience with Edge’s preloaded gas- or diesel-performance tuning and built-in custom-tuning capability. It gives enthusiasts an all-in-one solution to access additional power and response while monitoring critical vehicle information on the same display.
- Juice with Attitude CTS4 pairs the CTS4 monitoring platform with the Edge Juice inline power module for supported applications, enabling enthusiasts to monitor their vehicle while accessing shift-on-the-fly power-level control.
