Implement Impact Coefficient (from sw: 10.10.x & fw: 2.8.x)

An Implement Impact Coefficient is a tuning parameter used to correct path-tracking errors caused by implement.

When a vehicle pulls or operates an implement—such as a plow, seeder, or sprayer—factors like side slope, soil resistance, implement weight, dynamic hitch play, or trailing drift cause the attached equipment to pull the vehicle slightly off course or lag behind the theoretical trajectory.

The Implement Impact Coefficient acts as a dynamic correction factor. By adjusting this value, the autosteer controller modifies its steering response and path guidance calculation to account for the unique drag and steering influence created by that specific combination of vehicle and implement.

  • Software Version: App version 10.10.1 or higher

  • Firmware Version: Controller firmware 2.8 or higher

  • Pairing Model: Stored per unique Vehicle + Implement pair

Activating the Feature

  1. Open the application and navigate to Settings: Navigation.

  2. Locate the Implement Coefficient option.

  3. Tap Activate.

Note: The feature can be activated regardless of whether the physical device or controller is currently connected to the application.

Operating the Implement Impact Coefficient

 Adjusting the Parameter

  1. Start navigation with PowerSteer and build your navigation lines. The Wheel (Enable/Disable steering) and Gear (Settings) icons will appear on screen.
  2. Tap the Gear icon to open the steering adjustment parameters, where you will find the Implement Coefficient swiper control.  Each unique Vehicle + Implement pair defaults to 0.
  3. Drag the swiper to increase or decrease the coefficient value for your active pair combination.
  4. Begin guidance—the autosteer system will apply the active coefficient to adjust steering trajectory.
  5. Closing the settings screen automatically sends the updated coefficient value to the controller.

Note: If you keep the same vehicle but select a different implement, the system automatically creates a new pair configuration and resets the coefficient starting value to 0.
