Hello at last managed to make and test (tested on 100 cars - woot) EGR emulator for Opel/SAAB 2.0/2.2 (with electronic diesel control unit PSG16) 2002 --> onwards. Emulator is connected directly to EGR plug and air mass meter. EGR valve remains unplugged for all the time.

+ Advantages of emulator: no more crappy stuff with EGR, a little more power, better fuel economy

- Disadvantages: none at the time.

For more information PM please
