Yea, I could also lock the dizzy and do all of the timing curve in megasquirt too. The problem I see with that is, if you advance or retard too much, the rotor may fire to the wrong plug.

I didn't want the MSD box handling the timing. Then I would have 2 computers to hook up to for tuning.

MS3 has a few more features than MS2, non of which sounded like things I would use. Sequential injection's only advantage is better idle and lower low speed emissions. If you're making any power, sequential is pouring half of it's gas on a closed valve too.

MS3 also has logging and a few other neat things. And it's surface mount components, so the board comes pre populated. But I don't think either of the MS units do multiple sparks. That's the main reason I went with a MSD box.
