Pins D2, D3, and D4 for refrigerant and fuel pressure signals.
for reading/writing the internal flash memory, specific hardware modifications are typically required: Resistors: ) resistors to the board. me7.4.5 pinout
If you need:
The cover must be carefully pried open to access the internal memory and microprocessor. Pins D2, D3, and D4 for refrigerant and
Always use a stabilized 12V-14V power supply. Low voltage during a write sequence can "brick" the ECU. me7.4.5 pinout
: To enable Boot Mode, you must internally modify the board by adding two 6k8 ohm resistors and removing one existing resistor. MCU : This ECU typically uses the ST10F275 microprocessor. 📋 General Pinout Overview
