figuring out advance timing

Yea. That's the deal, its MAP not vacuum. Find a converter that lets you do that, or just use the table in the other thread to ballpark it. Eventually you may start thinking in terms of MAP but for your own sanity probably best to have conversion handy.
The conversion table assumes 101 kPa is atmospheric pressure.

Ok, sounds like while the turkeys in the fryer this afternoon I study up on MAP. But I think I am heading in the correct direction. This is a table I've been playing with the last couple days, haven't ran it in the car yet and don't want to go to big to fast. But sounds like I'm going the right way.

Thanks again, this is all new stuff for me.
