    cap/rotor indexing

    What is cap/rotor indexing, ops: either I know what it is, and don't understand the term, or I dont have a clue. Can someone explain this to me?

    I may have used the wrong wording...but I was refering to the rotor pointing exactly at the correct terminal when it fires so it can't jump to the wrong one and fire the wrong cylinder..maybe rotor phasing would have been a better term. :?

    I'm not trying to rock the boat,but...if you put your timing light on it and it shows 34 degrees,or whatever,then that's what you got....right,maybe not??I don't get it. ops:

    Typically rotor phasing is associated with a crank trigger.

    Rotor phasing comes into play if you are running a crank trigger or when you are using timing retards as in a nitrous engine. If you are running 36 degrees of initial timing, and retarding 16 degrees when nitrous is activated then you want your rotor phases so that it is optimum @ 20 degrees instead of @ 36, if not when your retard is activated you can have crossfire, which is not good with nitrous :roll:
