The timing at start-up is controlled via an element of the modules program. The program "element" engages as the magnet passes the sensor (first flip). The Hall Effect sensor switching on/off each time the magnet passes bye allows the module to calculate RPM which in turn is used to calculate timing needs. When the engine is running the timing is calculated relative to RPM and/or rate of RPM increase

FWIW: C&H Ignitions with SS are user programmable to the limits of full advance at either 4000 or 6000rpm and 20 or 26 degrees full advance. Default is 26 degrees at 4000rpm.
