With the free Curvemaker software and a USB programming cable you can set any curve you want into the Dyna/Ultima ignitions.

 

Finally got the Lowrider fired up, today & set the timing like Dale suggested . Actually timing was right where I set it at TDC, because when I put the timing light on it it was 34 deg. Now I understand the difference between a dial back & just a regular timing light. I painted a mark on the Inner Primary & Stator & timed it that way. Real easy to see for these old eyes. I also made a threaded plug to insert a 1' dial indicator in the sparkplug hole to find TDC. Real accurate.




Thanks for all the help.

Ride Safe,
Harold
