Car ECU, electronic control unit, also known as "driving computer", "car" and so on. From the use of speaking, it is a special computer controller for automobile. It is the same as the ordinary computer, by the microprocessor (CPU), memory (ROM, RAM), input / output interface (I/O), analog digital converter (A/D) and plastic, drive and other large scale integrated circuit. With a simple words to describe is that ECU is the car's brain".
ECU is widely used in all kinds of electronic control systems, such as electronic control common rail system, ECS system, electronic governor, electronic control distribution pump, electric control pump nozzle and so on.
ECU in accordance with the pre designed program to calculate the various sensor information after processing, and the parameters in the limit voltage level allowed, then sent to the relevant executive mechanism, executive control function of various predetermined. According to the input data and the data stored in MAP, the microprocessor calculates the injection time, the quantity of injection, the injection rate and the injection rate,
Time and so on. These parameters are converted to the time variation of power consumption with the engine running. Because the engine work is rapidly changing, and requires high calculation precision, fast processing speed, therefore, the performance of ECU should be with the development of engine technology and the development of the microprocessor memory is more and more big, the ability of information processing is more and more strong. With the engine speed and load as the basis, through the ECU processing and instructions to the injector and pump sending action, make each cylinder has the most appropriate fuel injection quantity, injection rate and injection timing, ensure each cylinder for optimum combustion. Control of fuel injection and fuel supply for the vehicle now ECU is the most basic function, cruise control, now the exhaust brake control, fuel preheating control, heating control, exhaust postprocessing equipment control, EGR and pressure control and so on, and by bus technology (such as CAN), AT, and dashboard EBS, data exchange and control, it is powerful. Look forward to our country in this regard the level of improvement, the real core technology to achieve the master.
CAR PROG Full is designed with regard to demands of our clients to have universal tool for odometers, dashboards, immobilizers repair, ECU repair and car radios, including advanced functions like EEPROM and microcontroller programmer, key ect.
1. Make the Universal tool - CAR PROG inside have powerful 16-bit MPU and full set of automotive interface drivers. In basic version you will get hardware with extra functions: 12 input/output pins forEEPROM in-circuit programmer, future possibility’s to make on the same hardware Microcontroller programmer, Immobiliser Transponder Key programmer with antenna adapter for 125/134 kHz, K-line diagnostic (dashboard odometer programming, immobilizer key programming), CAN line diagnostic,+5V/+12V output, USB, power supply only from USB.
2. Make the Low Cost tool - with CARPROG basic you will receive many extra functions (like car radio code calculator CC1, EEPROM programmer and VAG dashboard’s programmer by CAN) and all additional software’s you can buy extra according your need.
3. Make it User Friendly - Windows XP software, works without any installations, on all PC, use USB to PC link, all adapters schematics diagrams on-line.
