Hello all,
I have one of the source ready to run electronic distributors. Is there any way to tune the advance curve?

It seems like my car wants to run better with a lot of initial advance, but then the curve is too great and I'll get it to ping too much.

I have it running off ported vacuum and I guess I could try not having the vacuum advance at all but I prefer it if there is no way to change the advance curve.

Thanks for all ideas.
