Automobile Electronic Controller

---

Vehicle electronic controllers integrate microcontrol technology with high-performance processing cores to optimize factory system responses through programmable logic. The product lineup covers throttle sensitivity adjustment, turbo boost management, ignition delay for turbo protection, early fan activation, exhaust valve control, and RPM-based output triggers. The Cheng Jie team continues to develop a wide range of controller modules—from DIY tuning to professional applications—enhancing overall vehicle performance across all driving conditions.

Electronic Throttle Controller

---

Electronic throttle controllers use digital signal processing to redefine the response curve between the accelerator pedal and throttle body. Drivers can switch throttle response modes in real time based on road conditions and driving habits — from a responsive sport mode to an efficient eco mode — making every press of the pedal closer to the driver's intent. No modification to original wiring required; plug-and-play installation makes it the lowest-barrier upgrade for a noticeable improvement in driving feel.

Electronic Boost Controller

---

Electronic boost controllers provide digitally precise control over turbocharger boost pressure output, replacing the rough adjustment of traditional mechanical wastegate actuators. Drivers can set optimal boost curves for different RPM ranges and driving scenarios, delivering more linear and controllable turbo power. From daily driving to track competition, these controllers ensure stable and repeatable boost performance while balancing power gains with engine protection.

Exhaust Valve Controller

---

Exhaust valve controllers give drivers real-time control over the open and close state of valves in the exhaust system, allowing instant switching between quiet and performance exhaust modes. Shadow offers a complete range of valve control solutions covering four system architectures: OEM electronic valves, OEM vacuum valves, aftermarket electronic valves, and aftermarket vacuum valves. Whether your vehicle has a factory-equipped valve system or an aftermarket exhaust setup, there is a matching product available.

E-Drive 4S Electronic Throttle Controller

---

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 in these five function modes. In addition, Shadow converts the digital signal into an analog signal which makes the processing rate from 100 times/second to 1000 times/second. It has grown 10 times when we compared with the past. This also makes the throttle more stable and more flexible.

DEBC2 Electronic Boost Controller

---

Shadow digital electronic boost controller can set two sets of boost modes with different values and a set of original factory modes. By quickly switching these three modes to adjust turbocharging, it effectively improves engine performance and increases horsepower. The built-in forced pressure relief mechanism and the display interface provide the functions of monitoring and protecting the turbine, which is the most suitable modification for the turbo vehicle.

EBC-Lite Electronic Boost Controller

---

EBC-Lite is an electronic boost controller developed from Shadow's DEBC II control logic. With a more compact display and simplified interface, operation is more intuitive, and installation is cleaner and more streamlined. For turbocharged vehicles, precise boost control is the foundation of stable power output. EBC-Lite helps users take control of when boost engages, how quickly pressure builds, how stable the plateau is, and when to protect.

Radiator Cooling Fan Controller

---

The Shadow Radiator Cooling Fan Controller is designed for 12V vehicles and can directly drive OEM or aftermarket cooling fans, activating cooling earlier to keep the engine within its optimal operating temperature range. The package includes a Shadow temperature sensor that can be installed on the engine hose or the controller itself for real-time monitoring. The controller features a digital LED display that clearly shows water temperature, oil temperature, and voltage. Users can freely set the fan activation temperature, while the smart fan-stop logic and warning functions ensure stable engine operation, prevent heat damage, and effectively reduce the risk of overheating.

X-FLAP OEM Exhaust Valve Controller

---

Many European performance vehicles come factory-fitted with electronic exhaust valves — but valve behavior is controlled by the driving mode, not the driver. Even on vehicles equipped with a stock performance exhaust, regulatory constraints often restrict valve opening angles — holding back both the exhaust note and flow efficiency. X-FLAP OEM Exhaust Valve Controller works without modifying the factory system, putting valve control back in your hands. Switch states instantly via remote or smartphone app, independent of driving mode. Installation uses OEM-spec connectors — no wire cutting required — and can be fully removed to restore the original configuration. Every unit includes a built-in Decode Module (signal loopback mechanism) to keep the ECU reading normal signals, eliminating the need for a separate shielding device.

X-FLAP TL Electronic Exhaust Valve Controller

---

Many vehicles equipped with multi-angle electronic exhaust valve motors rely on the ECU to dynamically adjust valve opening based on RPM, throttle position, drive mode, and vehicle state. As emission and noise regulations tighten, even with the factory sport exhaust engaged and the drive mode set to Sport or Sport+, the valves may not fully open — often staying at a partially open position. The X-FLAP TL is Shadow's electronic exhaust valve control solution developed specifically for new-generation Mercedes-Benz. Beyond switching valve states directly via remote or smartphone app, it introduces a half-open correction feature in NOR (OEM Follow) mode: when the ECU has commanded the valve to open but still restricts the actual opening angle, X-FLAP automatically corrects it to fully open. New-generation Mercedes-Benz electronic exhaust valves incorporate more comprehensive communication feedback, actuation monitoring, and diagnostic mechanisms. Using a controller that doesn't properly interface with the factory control logic — or disconnecting the factory valve motor entirely — can generate related fault codes, and may even trigger Limp Mode, restricting engine output or boost pressure. The wiring harness uses OEM-spec connectors for true plug-and-play installation — no wire cutting required. It preserves the factory operating interface, removes the factory opening restrictions, lets the sport exhaust truly open all the way, and puts control back in the driver's hands.

X-FLAP TVL Vacuum Exhaust Valve Controller

---

Many European performance cars and supercars come equipped with factory vacuum-actuated exhaust valve systems — using engine vacuum pressure to control valve position through solenoid valves. The factory ECU manages when the valves open and close based on RPM, throttle position, and drive mode. In practice, this often means the valves won't open when you want them to, or won't close when you need them to — leaving the driver with no real control over exhaust valve behavior. The X-FLAP TVL series is Shadow's solution for these vehicles. Through the app or the included wireless remote, you take direct control of three valve states: ON (fully open), OFF (closed), and NOR (return to factory ECU logic).
