The EEPROM Method

The EEPROM is an electrically eraseable read-only memory that is programmable (EPROM). It is a permanent CMOS chip that stores data in computers as well as other electronic devices. It can be programmed with individual bytes, which can be accessible via an address. Each byte can be either a 1 (or an 0). When the byte is written on the chip, it becomes active and, when it is read the bits are decoded to give instructions.

When writing to an EPROM, the drain and source terminals are grounded. A high voltage channeled from the control gate passes through the silicon oxide to the floating gate which causes electrons to flow through it and get trapped. The gate's contents to change from a 0 to one. If the voltage is removed, the gate becomes uncharged, and the contents of the EEPROM are erased.

EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations, and also the status of remote keyless system components. They can be used to maintain state between power changes. This is crucial for ICs powered by batteries since a sudden loss of power can cause the chip to reset.

There are a couple of ways to reprogram an EEPROM. However, most of them require the car to be in a specific state. For example, it may be necessary to disconnect the ECU from the battery or to take the EEPROM out and then connect it to an test board. The contents of the EEPROM chip can then be read by an EEPROM Reader and copied to another chip.

It can be a time-consuming process, and it is difficult to find the right data. Most people choose to have their cars reprogrammed by a professional instead of trying this at home.
