Sharper Throttle Sensitivity
The Shadow electronic throttle controller uses the throttle signal to change the throttle response time and accelerate the vehicle forward. You can feel the power changes by lightly stepping on the accelerator across five function modes. Shadow converts the digital signal into an analog signal, raising the processing rate from 100 to 1000 times per second — a 10x improvement that makes the throttle more stable and more flexible.
Five Function Modes
• Power Mode: increases throttle sensitivity and initial response for better launches. • Launch Control Mode: greatly improves throttle response, delivering full power within one second. • Eco Mode: reduces the electronic signal to slow acceleration and lower fuel consumption. • Anti-slip Mode: temporarily limits horsepower output on high-power vehicles, maintaining tire grip on slippery slopes, mud, or snow to reduce slipping risk. • Anti-theft Mode: cuts off the electronic signal so the pedal signal cannot be detected when starting, preventing the vehicle from moving.
Modular Design — No Damage to Factory Configuration
Shadow has developed more than 20 types of dedicated cable sets, with 96% of cars on the market supported. The controller is plug-and-play via the dedicated cable set, requiring no damage to original parts and not affecting the new car warranty. Suitable for European and American makes (BMW, VAG, Mercedes-Benz) and Asian makes (Toyota, Honda). If you change vehicles or transfer the product, just swap the cable set — the control box and display can continue to be used.
Fits Every Type of Engine Vehicle
Whether gasoline, diesel, naturally aspirated, turbocharged, hybrid, or electric — all can install the Shadow E-Drive 4S. Its light, handy design installs easily in any corner of the driver's seat. The soft silicone buttons offer a three-dimensional touch with good feedback, letting users focus more on road conditions while driving.
