Posted May 4, 20177 yr comment_519879 I have a 1982 280ZX Turbo drivetrain in 76 280Z. The stock ECU.number is A18-601-042. I have a chance to buy a spare ECU from another 1982 280ZX Turbo and the part number is A18-603-045. They are both 5 speeds.Does anyone know if these are compatible?TIA Sent from my iPad using Classic Zcar Club mobile Link to comment https://www.classiczcars.com/forums/topic/57639-ecu-compatibility/ Share on other sites More sharing options...
May 4, 20177 yr comment_519899 This Nissan guide says that the second one is for a 1983 Turbo. You could browse through the FSM EFEC sections and see what might be different. The ZX's got so packed with emissions devices, it's hard to say what might have changed. I would open the wiring diagrams for the EFEC systems and compare. http://www.classiczcars.com/files/category/14-280zx/ Link to comment https://www.classiczcars.com/forums/topic/57639-ecu-compatibility/#findComment-519899 Share on other sites More sharing options...
