Steps for adapt Emulator: 1. Read PIN by UHDS or do it by self from dump of EEPROM from ECU 2. Use Soft PSA_Emu_Tool1.exe for prepare eeprom 24c01 on EMUltor in soft Select Baud 500k and write proper PIN. soft prepare eeprom 24c01 . Use any programmer for write it to eeprom on Emulator. 3.Solder jumper J1 on Emulator and solder 4 wires (+12V (15), GND , CAN H , CAN L). if you power ON ECU led should be ON. if LED is OFF mean wrong code is set in EMU (difrent as in ECU) if LED blinking problem is with connection EMU to ECU (EMU dont see request from ECU)
