Modification of the car obd2 software trip computer (ECU)

Modern car in every aspect of the application of  obd2 software computers, microcomputers in the driver's seat alone can set the memory seats, mirrors and steering wheel down, motorists can quickly switch to use previously set to their ideal driving position. But in the eyes of modification enthusiasts, the computer has only one chip, and that is to control the vehicle power Engine Control Unit (ECU engine control unit). Superchips apply this year, foreign car chip performance brands have entered the Chinese market, a relatively well-known brand Superchips, REVO, NEUSPEED, which REVO, NEUSPEED mainly focused on the modification of the mass of cars, while the 30-year history in the UK more than 90% of the domestic market models.1, trip computer (ECU), the basic principles ofLet the engine generate power, we first want a certain proportion of air and fuel supply to the cylinder (generally air-fuel ratio AFR value set at 1: 14.7, ie a fuel, 14.7 parts of air, this proportion of the most environmentally friendly required), then at a suitable timing of this air-fuel mixture ignited, expanded gas generated in the combustion process will just reach the cylinder stroke vertex piston pushdown  OBDII Code Info to generate power. The basic essentials looks very simple, and should not have access to superb electronic about, but the reality often than expected complicated, first of all the driving speed of the car is not fixed, the higher the driving speed, the engine will need to obtain more much air. In order to maintain the stability of the air-fuel ratio cases, the car's fuel supply system must be corrected accordingly fuel supply. In each moment and conditions to make the right amount of air-fuel mixture into the engine at the best time for complete combustion, the ideal realm of engineers have been pursuing since the invention of the automobile, but the mechanical carburetor and The ignition system is always up to less than such a comprehensive and perfect effect until computerized electronic ECU before this situation is completely different.Electronic ECU is a microcomputer, within integrated circuits and other sophisticated electronic components, and acts as a "central nervous system", which is stored a large number of the ideal value of the  OBD2 Scanner Code supply of fuel corresponding to different weather conditions and engine operating conditions and the ignition timing The value of the portfolio. "Central nervous system through the intake manifold air flow from many sensors, temperature, throttle opening angle, abridged shaft speed data collection, analysis and calculations, in thousandths of a second high-speed oil to meet the real-time environment and working conditions,
