1. on Emu eeprom 24c02 program by programmer with file : eep_24c02.bin 2. Solder 4 wires ECU<>EMU as on picture 3. if you can you can make your original file ECU for virgin 4.Connect power to ECU . At first power on LED will blink very fast - mean that code learn ok ,every next power on LED will be ON- mean EMU and ECU are learned Warning !!! In car you can remove ignition coil( because original Immo in car and EMU can disrupt). if LED on EMU stay OFF then mean code in EMU and ECU are not same -probably reason is ECU is not made virgin. if we power on EMU without connected CAN to ECU LED will blink slow ------------------------------------------------------------------------------ another solution is write orginal codes from ECU to EMU . in this case we read only eeprom from ECU and program itin 24c02 on EMU. Example: TC1797 Code in EEprom adr $0108 : A7 51 17 64 A2 7D k5 k3 k1 k4 k2 k0 Need to Writre into 24c02 Emu 24c01: 7D 17 A2 51 64 A7 (k0..k5) //not important ECU request 0xC3,0x9A,0xBC,0x69,0x0A,0x2C
