Where to set duty cycle for a successful Ca emissions test?
I have get the wife`s 87 190e 16V smog tested at a test only center. Anyone tell me where you set your duty cycle. Probably close to the factory specs (50%?), but should I lean it slightly?
Currently its adjusted at 50% duty cycle and approximately -2.3 ma at the EHA. Go leaner? Or leave it and try. $45 a pop.
