Curious if anyone is running one of these distributors you can totally control via phone app?  Looks very interesting.  They say their module never fades like others do at high rpm.  They have plenty of videos of it in action

I looked into that when I was thinking of turboing my car. That is the only thing I can see that setup being good for.

I got my timing set where it needs to be... and it has been there for 9 years I think? Less timing gets worse performance and mpg. More timing gains me nothing. With the low compression I have, the car doesn't need spark retard to start. Why would you need to tinker with timing on the fly once you are dialed in?

Yes, any power adder this would be great to have.  Maybe as well if you go TBI?  The only other benefit I can think of is down the road things if you keep changing things or for some reason you have a finicky engine and timing swings are needed that a mechanical distributor can't do?

If you don't have something dialed it would be a lot easier, especially if you don't have access to a distributor machine.

This is exactly what I was thinking.  Distributor machines are hard to come by and not many know how to correctly use them.
