  • Automobile Electronic Controller
    Automobile Electronic Controller

    Automobile electronic controller use electronic micro-control technology with high-performance processing core to write control commands and modify the original parts of the vehicle. Electronic Throttle controller can change the vehicle acceleration sensitivity. Digital Boost Controller increases the upper limit of turbo boost. Turbo Timer extend the flameout time. Engine cooling fan controller let the fan turn on in advance to dissipate the heat. Electric exhaust valve controller can switch the exhaust valve pipe manually. Digital tail Light Controller makes the tail light more active.


  • Electronic Throttle Controller
    Electronic Throttle Controller

    Electronic Throttle Controller uses a 3-core microprocessor to make the processing rate reach to 1000 times per second. Electronic throttle controller has DAC (Digital to Analog Converter) that is used to improve the accuracy of electronic signals and reduce the voltage to 5V in order to make the original vehicle computer (ECU) interpretation not to bring about the error easily.


  • Digital Electronic Boost Controller
    Digital Electronic Boost Controller

    Digital Electronic Boost Controller use electronic control 48 times/sec high-frequency solenoid valve to release gas pressure with whole new computing boost technology, Duty value and Gain value can be set to control the physical properties of Actuator/Wastegate. In addition to the overpressure cutoff protection mechanism, Digital Electronic Boost Controller can also release the pressure when it reaches to the setting value. Moreover, an air-fuel ratio cutoff function is also added to the system, which can connect to the AFR sensor and set the AFR value. It will release the gas pressure to protect the engine when detect the AFR is too thin. A user-defined formula for air-fuel ratio is also added.


  • Engine Cooling Fan Controller
    Engine Cooling Fan Controller

    Engine Cooling Fan Controller is equipped with two channels of sensors which can detect the temperature of cooling water temperature and lubricating oil temperature. It is displayed by a seven-segments display with a 1/8NPT temperature sensor.


  • Electric Exhaust Valve Controller
    Electric Exhaust Valve Controller

    Electric Exhaust Valve Controller can remote control electronic exhaust valve pipe on and off, it also supports vacuum and electronic exhaust pipe valve systems. Electric Exhaust Valve Controller remote control adopts Bluetooth 4.0 wireless transmission, 2.4GHz transmission rate and uses a 16MHz processing core to process signals quickly. The effective signal transmission distance is up to 50 meters and comprehensively reception. It has the characteristics of accurate matching and zero error to avoid any wrong actions occurs. With low power consumption, it can stand by for more than 17,280 hours.


  • Digital Tail Light Controller
    Digital Tail Light Controller

    Digital Tail Light Controller uses the original vehicle connector cable not only ensure no damage happen and increase installation convenience. Digital Tail Light Controller can independently control the original tail light signal by program simulation and rearrange the dynamic. According to the turn signal, brake light, hazard waning lights, low beam and etc., our product is able to do the light signal changed and show 27 kinds of dynamic modes. Digital Tail Light Controller can be remotely control from outside or operated in the car based on radio frequency technology (RF). Not only have built-in reverse current protection mechanism and over-voltage fuse device, but also set BY PASS channel to ensure that when the product is abnormal, it can automatically switch the original factory light. Digital Tail Light Controller can set the parking light mode so that after the vehicle is turned off and parked, the tail light can be turned on as a warning.


  • OBD2 Diagnostic Multi-Functional Display
    OBD2 Diagnostic Multi-Functional Display

    OBD2 diagnostic Multi-Functional Display is plug and play. It can quickly reads data from the ECU through the Controller Area Network (also called CAN or CAN bus) and use a 16MHz processing core to display current driving information at the maximum rate. OBD2 diagnostic Multi-Functional Display screen is composed of a 7-segment display and LED, which can set multiple groups of warning values. When the data reaches the setting value, it will be warned by flashing. It can flash 6 groups of information at the same time.
