Hi looking for a bit of info, Ive done a search on setting the timing and 20degrees seems the common answer but I was talking with a mate and he remembers something about having to earth a pin (poss no 10) in the diagnostic plug to in effect put the car into service mode to allow it to accept the new setting.
could have been on an 200sx or similar, or is it just set useing the timing light and thats it? Thanks
