    Re: Results Using The New Version Digital MSD 6A & 6AL

    I saw 4 timing lights on Larson's Nova all reading something different, all different reputable makes, owned by reputable drag racers, so your mileage may vary. But I have had multiple timing lights on my car, and because I know where I've set the trigger wheel teeth on my balancer and the MegaSquirt commanding timing referencing where those teeth are, my own timing light can't be off more than a degree or two if at all.

      the timing just doesn't bounce around, it will also read wrong........
      How could that be? the "multiple spark discharge" happens at the same time a "single spark discharge" happens in a non-MSD ignition. If the sparks are sparking at the same crank angle, then it ain't the fault of your ignition if your light reads wrong.

      Again, from experience a little newer than 40 years ago. :-))

          Aha, so Alex's experience is twofold: (1) he read it on the internet and (2) he once used a timing light on an MSD box back in 1971.

              Also, it should be known that there is no such thing as a timing light that is "correct."

              They are just like O2 sensors - each has their own personality (mechanical or electrical delay, in this case). The whole point of timing an engine with one is to use a light that produces repeatable results, then use it to find the best timing for the most power (if that's what you are looking for).

              If I had a pile of ten lights, I'd expect ten different results on any engine. The only thing that matters is repeatability and consistency.
