For Adapt EMU to ECU you have to write to 24c02: adr $07,$08,$09 ,$15,16,$17 =$72 adr $0A,$0B,$0C ,$18,19,$1A =$8E For example file Terrano_modyfiedForEmu_24c02_ok.bin has this byte already sets Possible troubles: adr: $06,$14 - should be $00 , if in this place is 01 mean ECU is unlocked state and EMU will not blink till car not start. If in this place still is 01 after probe of start of car that mean - car not start from other reon as immo. LED on EMu after power up ECU must switch ON. After 2 time power ON ECU next power on will not set LED ON because byte (adr $06, $14) is set to 1. If you want to be sure that EMU works properlly please set valeue adr $06,$14=$00.
