DYNATEK DYNA 3000 is an ignition module for the Honda Shadow 1100 motorcycle. It offers ten built-in advance curves, allowing you to optimize ignition timing for your engine's specific needs. The DYNA 3000 also features a nitrous/blower retard mode, which can be programmed to retard ignition timing by up to 10 degrees when the white wire is grounded. This is useful for preventing detonation when using nitrous oxide or a supercharger.
