MODULO ACCENSIONE SINGLE FIRE

DYNATEK, DYNA-S IGNITION MODULE  SINGLE FIRE

Dyna-S ignition module for single fire applications. Comes complete with rotor. Can be used for single or dual plugged heads. The required mechanical advance unit must be purchased separately. Note: Dyna coil recommendations: Dyna 5 Ohm for street use, Dyna 3 Ohm for race use. Note: It is recommended to use ignition modules & coils of the same manufacturer. Intermixing different brands may cause premature failure. Note: Difference between Single & Dual Fire: – Dual Fire – This is the way the earlier, pre-Twin Cam, engines work. A single coil is used and both spark plugs fire simultaneously. This is the simplest system. The ‘wasted’ spark is sometimes said to be horsepower robbing. – Single Fire – This is the way the stock 00-up Twin Cam engines work. Two separate coils will fire the spark plugs independently and only the spark plug of the cylinder that is on compression stroke will be fired. It is said that these engines vibrate less and can improve power. The effects will become more pronounced with hotter cams and higher RPM. Note: For the dual fire Dyna-S ignition module see 902525.

Fits:   70-99 Big Twin (excl. TC) and 71-03 XL Sportster
