REFLASH ECU AND ECM
The ECU or engine control unit, or also known as the ECM or engine control module refers to the digital component that it embedded in many of today’s latest vehicles which run a program which holds, controls, and reads things such as O2 and CO2 sensor output, key data, engine performance, engine RPM, timing variable valve, fuel to ratio, and so much more.
The ECU is basically an Electronically Erasable Programmable Read Only Memory or EEPROM computer chip which means that the chip will retain the data with no periodic electronic power. This means that loss of electric power is not going to make the chip lose the programming data.
When you accidentally lost the master transponder key on your vehicle, there will be no interface to make a brand new key. This is when it becomes important to re-flash ECU and ECM. Also, if the ECU or the ignition is going to be replaced on your vehicle, a re-flash service will also be necessary.
When you speak of re-flashing the ECU and ECM, this will involve an electronic deletion of read only program before downloading new and more updated map information. Most of the time, when the ECM is re-flashed, a brand new map is being assemble which will give the engine the chance to run faster and better although this might also decrease its reliability and durability.
