Why EMP glitch?
Bosch protects the MDG1 generation so that reading and writing via classic bench or boot methods is blocked. Until now this often meant shipping the ECU, waiting for an external unlock, or removing and soldering the circuit board.
With the EMP glitch, a precisely timed electromagnetic pulse briefly disturbs the processor. At exactly that moment, access is unlocked. The ECU only needs to be opened – the board stays in its housing, nothing is soldered and no component is removed.
After the one-time unlock, the ECU can be read, backed up and written with the tuned software in bench mode as usual.
