Lots of good stuff in the forums on setting ignition timing using an inductive strobe light BUT I don’t understand why I can’t just use my old light simply wired in series with the no.1 plug. It will surely flash every time the plug sparks so job done, I’d have thought.
Yes indeed. You set the base idle timing, and the ECU adds advance to that as required by engine conditions like throttle setting, revs and airflow. Basically you’re doing exactly the same as you used to, it’s just that a computer is now attached where the vacuum advance used to be so you have to disconnect that first.
