EOBD Galleto Flasher 1260

Quantity Order:

Within the engine systems, the ECU uses a closed-loop control system to monitor the outputs of a system in order to control the input to a system on managing the emissions and fuel economy of the engine ( as well as a host of other parameters) . It gathers data from dozens of different sensors and knows everything from the coolant temperature to the amount of oxygen in the exhaust gas. With these data
it performs millions of calculations each second, including looking up values in its tables, calculating the results of long equations to decide on the best spark timing and determining how long the fuel injector should open. The ECU does all of these to ensure the lowest emissions and best mileage achieved for the car.
