MGF MEMS ECU (MY until 2000, no VVC)

ENGINE MANAGEMENT SYSTEM  
ENGINE MANAGEMENT SYSTEM - MPi MEMS 1.9 MGF until VIN 522572 CONNECTOR No C0159 (black)
ENGINE MANAGEMENT SYSTEM - VVC MEMS 2  
ENGINE MANAGEMENT SYSTEM - MPi/VVC MEMS 3 MGF since VIN 522573, MGF Trophy, MGTF  
VVC Owners should have a look to Tom White's website with alls detaisl about both connectors and lots of information about sensors
