Pederzini advance curves, graphical?

[jhord]

Hello all-

I am developing some different spark maps for a programmable CDI to fit the carbureted SS models. I am looking for charts of the various Pederzini ignition module advance curves. I know I have seen them somewhere on the net, I just can't find them again. Doug Lofgren has some written info on his site, but I'd like the graphs so I can plot something a little more precisely, rpm vs. advance. Then I can try out "Pederzini maps" on the dyno. TIA!

J.D.

i think someone posted them recently on dml, maybe the thread brian started.


generally they have the same at idle, 30 max then drop back at some point. i wrote on one thread what mine do.
