| What is the UNICHIP? The UNICHIP is a complex, re-programmable microcomputer, which works in conjunction with the Engine Management System (EMS) already fitted to most modern cars. The EMS on modern fuel injected cars, control the fuel and the ignition timing by use of an Electronic Control Unit (ECU). Sensors mounted around the engine take readings and these are compared with a reference table held within the ECU (known as the MAP). The ECU then sends the desired outputs to the engine's ignition and fuel circuits. What are the disadvantages of the standard ECU? Manufacturers spend many years, and millions of £'s, developing ECU's, but they must make compromises to take into account, i.e. differing climatic conditions, the quality of fuel and servicing, and even production tolerances. How does the UNICHIP improve your car's performance? The UNICHIP intercepts the signals from the engine's sensors and allows a skilled rolling road operator to modify the fuelling and ignition timing to achieve the maximum benefit from your car's engine. This gives both economy at part throttle, cruising speeds, and maximum BHP and torque outputs at full throttle. |
