What kind of code, to avoid having to dismantle the engine control unit?

Hello everyone.

I’m doing a Mercedes Benz Actros engine control unit. I want to write a program that you do not to disassemble the engine control unit.

Thank you in advance for your answers.

I want him to read the EEPROM content

You don't need a program for that. Just leave it alone.

Him? Does your Arduino come equipped with male anatomical features?

How do you intend to connect the Arduino to the ECU? How much EEPROM does the ECU have? What are you going to do with the data?

The Arduino type: Arduino UNO R3

I would like the Arduino is connected via the K-line electronics.Az EPROM content is matched to the flash memory and therefore I need the EPROM content. The Electronics into two EPROM away.
