Drive your RC car like a real race car. PIT SimBridge transforms your sim racing setup into an RC controller. Connect your wheel, pedals, and shifter to the PIT Transmitter, and drive your RC vehicle with the same hardware you use for sim racing — all wirelessly. HOW IT WORKS Your sim racing wheel, pedals, and shifter connect to the PIT Transmitter via USB. The PIT Transmitter sends your inputs wirelessly to the PIT Receiver mounted in your RC car using the ELRS protocol with built-in security. PIT SimBridge is the app that ties it all together. EASY SETUP Pair your PIT Transmitter via Bluetooth in seconds. The app walks you through Wi-Fi configuration and device connection with a simple step-by-step wizard. Set it up once and the app remembers your devices. REAL-TIME CONTROL See your steering, throttle, brake, clutch, and gear inputs live on the dashboard. Monitor all 12 RC channels in real time. Transmission runs at up to 250Hz for responsive, lag-free control. FULLY CONFIGURABLE - Calibrate steering, throttle, brake, and clutch axes - Choose from linear, exponential, or logarithmic response curves - Set deadzones, output ranges, and axis inversion - Configure ESC modes (Separate, Traxxas, Standard, or Custom) - Fine-tune steering endpoints and throttle ranges - Map wheel buttons to any of 12 RC channels - Enable smooth deceleration, pit limiter, and reverse mode - Save and switch between multiple profiles LED STRIP SUPPORT Control RGB LED strips on your RC car with up to 30 LEDs. Choose from global color, per-LED, or zone-based modes with a full color wheel picker. FIRMWARE UPDATES Keep your PIT Transmitter and Receiver up to date with over-the-air firmware updates, right from the app. PRIVACY FIRST No accounts, no tracking, no data collection. Bluetooth is used for setup only. Wi-Fi stays local. Your data never leaves your device.
