I have a 1999 dyna. Engine is built to a 98ci, heads are decked and port and polished, has a fueling 594 cam, as well as running larger valves in the heads. Obviously I wouldn't be doing the 36A curve, what would be the recommended start for this build?

Hi Nathan,

Thank you for your interest in Dynatek ignitions. For this engine setup we would suggest starting on Curve 28B and see how that runs. If it runs well with no signs of detonation then try 30B and up. If you encounter any pinging then back off to the previous curve setting. If we can be of any future assistance please feel free to contact us anytime.
