Learn how to install Pedal Commander on your Rivian R1T or R1S in minutes. This step-by-step guide covers preparation, placement, and testing for a custom throttle response.
Quick answer
Installing a Pedal Commander on your Rivian R1T or R1S takes about 10 minutes and requires no tools. Just secure the controller over your accelerator pedal, plug it into the OBD-II port, and select your desired response mode.
Before you start: compatibility check
Pedal Commander is designed specifically for 1st Gen (2022+) Rivian R1T and R1S models. It supports a wide range of drive packages including Adventure Dual-Motor, Quad-Motor, and Ascend Tri-Motor configurations. Make sure you select the correct model when ordering—the R1T and R1S versions are separate products due to different pedal shapes.
If you have a newer Rivian model or a variant not listed in the product options, contact support to confirm fitment before purchasing.
Tools and setup
You won't need any tools—the Pedal Commander ships with a mounting bracket and an OBD-II cable. Park your Rivian on a level surface, turn off the vehicle, and give the cabin a moment to power down completely before starting.
Installation steps
- Position the Pedal Commander over the accelerator pedal: Place the controller directly over the accelerator pedal, aligning the mounting bracket so it sits flush. The bracket uses a tension-fit design—press firmly until it clicks into place. Adjust the angle slightly if needed for a natural foot position. Check that the controller does not interfere with the brake pedal or your resting foot.
- Plug the OBD-II cable into your Rivian's diagnostic port: Locate the OBD-II port under the dashboard on the driver's side. It is usually near the left knee area. Insert the cable until it clicks. The cable is long enough to route discreetly along the edge of the floor mat. Avoid forcing the connector—if it doesn't slide in easily, check orientation; the port is keyed.
- Select your response mode: Turn the ignition to 'On' (do not start the engine). The Pedal Commander will power on and show the current mode—usually Eco (green). Press the mode button to cycle through Eco, City, Sport, or Sport+ modes. Choose Sport for a sharper throttle response or Eco for smoother acceleration. Start with City mode for daily driving; it reduces lag without feeling too aggressive.
- Test the setup: Start the engine and gently press the accelerator. The response should feel immediate and consistent with the selected mode. Drive a short distance to confirm the controller stays in place and the cable does not obstruct pedals. If you feel any delay, recheck the bracket fit. If the throttle feels unresponsive, unplug the OBD-II cable and plug it back in—this resets the connection.
