Tools like DFB Technology allow for a full read and write of the Micro and EEPROM (typically a 95320 eeprom ) via these pinout connections. Essential Precautions
Power & Ground
Before attempting to match pinouts, verify you have the correct unit. The ME7.4.5 has distinct physical characteristics: me7.4.5 pinout
– they are physically incompatible.
Bosch ME7.4.5 is a common Engine Control Unit (ECU) used primarily in Peugeot and Citroën (PSA) vehicles with the 1.6 16v (TU5JP4) engine Tools like DFB Technology allow for a full
: Remove one specific resistor on the ECU board and add two 6.8k ohm resistors . Bosch ME7
