This is a brand new PROGRAMMABLE Big Dog Motorcycles Ignition Module for all 2005-11 Carbureted Big Dog Motorcycles.
The unit is "plug & play" with JST connectors to connect to the stock connections in all Big Dog 2005-2011 models.
Don't settle for the stock ignition module! Setting #3 is the same option for stock Big Dog's, if you want to get a little more power you can try setting #2 . If you have had or maybe planning on any engine modifications you can take advantage of the pre-programming!
MADE IN THE USA!
See the document from Thunder-Heart with the pre-programmed curves and the numerous options you have with this module.
