ELECTRONIC ENGINE CONTROL (EEC) SYSTEM
The powertrain control module (PCM or ECU) contains both engine and transmission microprocessors. Operating information, as well as concern information, is communicated between the 2 processors through the controller area network (CAN). Both can be programmed individually.
Fuel control is accomplished by the PCM and the fuel injector control module (FICM). The 2 modules communicate operational information through private J1939 CAN communications.
The Ford EEC system provides optimum control of the engine and transmission through the enhanced capability of the PCM. The EEC system also has an on board diagnostics (OBD II) monitoring system with features and functions to meet federal regulations on exhaust emissions.
The EEC system has 2 major divisions: hardware and software. The hardware includes the PCM, FICM, sensors, switches, actuators, solenoids, and interconnecting terminals. The software in the PCM provides the strategy control for outputs (engine and transmission hardware) based on the values of the inputs to the PCM. The software in the FICM provides the strategy control for the fuel injectors based on the values of the outputs from the PCM. The EEC hardware and software are discussed.
The PCM receives information from a variety of sensor and switch inputs. Based on the strategy and calibration stored within the memory chip, the PCM generates the appropriate output. The system is designed to minimize emissions and optimize fuel economy and driveability. The software strategy controls the basic operation of the engine and transmission, provides the OBD strategy, controls the malfunction indicator lamp (MIL), communicates to the scan tool through the data link connector (DLC), allows for flash electrically erasable programmable read only memory (EEPROM), and controls failure mode effects management (FMEM).
The Unichip is a sophisticated, piggy back computer that works in harmony with your vehicle’s factory computer. It electronically resides between your car’s ECU and engine, giving you full control over your vehicle’s engine management system. The Unichip does not alter your vehicle’s factory engine management control unit in any way.
Increased Engine Power
The Unichip delivers torque gain and increased power across the entire RPM range. Power gains up to 13 % is common in normal aspirated vehicles and in turbo vehicles a 30% gain as measured by an accurate chassis dynamo-meter can be expected. It is however difficult to predict exact power gain because it is influenced by the design and condition of the engine and the factory calibration of the engine control unit. That said, the Unichip is far more advanced than “generic plug-in performance chips” and it delivers the most personalised power result every time.
Fuel economy is at the top of car manufacturers priority lists these days. However, even in this rat race for best fuel economy the Unichip stands it’s ground. The Unichip will almost always improve fuel economy in vehicles with even the slightest modification such as an aftermarket air intake. This is especially true and more obvious in older and highly modified vehicles. We receive frequent testimonies from customers about increased fuel economy after installing the Unichip.
Works in Harmony with ECU
A major advantage of Unichip is that it works in harmony with the factory ECU to enhance and unleash the best possible performance result without compromising engine durability. Unichip is loaded with an operating system and program which enables it to correctly communicate with your vehicle’s ECU without making physical, electrical, or electronic changes to the factory computer.
Suitable for Most Vehicles
The Unichip is a universally applicable module designed to work in virtually any vehicle. Most EFI cars, whether normally aspirated, turbocharged or supercharged, respond extremely well to Unichip enhancement. It is individually programmable and fully adjustable to cater to exhaust headers, cat back exhaust systems, high flow air cleaners, performance cam shafts, or larger turbochargers and inter coolers.
