Car ECU meaning
ECU means Engine Control Unit it is a programmable microprocessor unit and it is sometimes known as mapping which is done via a laptop and is linked up with a USB cable whilst the engine is in operation motionless. Before emissions laws came in to being, it was feasible to make a car engine without using ECUs. The ECU uses closed-loop commands; this is a system that monitors the output to monitor the input, this manages the emissions and fuel as well as many other engine components.
About Old Style ECU
The old ECU does not offer suitable monitoring for the new ECU configurations, the old style used analogue techniques to determine input and outputs, technicians had to look-up tables that were stored in a digital ROM chip to achieve the any engine details. The disadvantage of ROM chip systems is that the pre-computed engine details are only favourable for the older engines. As the car engine becomes old, the old digital ROM chip is less able to balance the engine as opposed to the newer CPU systems for the newer cars. Before a ECU was built-in to cars the carburettor controlled the amount of fuel flowing in to the cylinders. It all had to be set manually and frequently needed attention when it was time for the car to be next serviced.
About Modern Style ECU
The Modern ECUs use a microprocessor which processes the input and output sensors in real time, this enable car parts to be altered or programmable. The ECU contains all the hardware and software information, with this a qualified technician can alter a turbocharger, an intercooler, Ignition, revving limits, water temperature correction, transient fuelling, low fuel pressure modifier, closed loop lambda, exhaust system, and switch over to run on alternative fuel.
