- Flashing ECU via BDM
Most ECUs from 2002 to 2008 (and some later) have a special communication port on the motherboard called a BDM port. To access this port you need to take the ECU out of the car and open it. In this way ECU will receive a stable 12V power, and can be flashed over and over again. So this is most safe way for ECU programming. And you can also backup if something goes wrong with the flashing via OBD.

KTAG V2.13 Master version (also does boot mode, no token limits) €75
- Flashing ECU via Boot Mode
You need to take ECU out of the car, and program it on the table while connecting special cables to the ECU's connector pins. Sometimes you also need to do some soldering, like adding resistors to the motherboard…

- Flashing via soldering EEPROM
You can use this way for older car ECUs and a big percentage of truck ECUs. You also need to take out the ECU, open it and desolder out the EEPROM chip. Then you can read EEPROM chip using an EEPROM programmer. After read, file is modified and then programmed back on a chip (or on a new, empty one). Then you solder the chip back into the ECU.
