Ignition cut limiter

Postby LooseEndsDrifters » Thu Dec 28, 2017 8:30 pm

Would reducing the dwell duty cycle (to 0) cut ignition at that rpm?

Any harm in trying this?

Likely it might since there would be a 0 charge time. However the tables don't work as you would expect since it uses a scheduler

The scheduler starts with ignition time - dwell time (to charge the coil) and then releases charge when dwell time expires

The RPM table simply increases the dwell time to keep dwell time constant throughout the RPM range (as RPMs increase the pulses used to generate final dwell time decrease)

The only dangers in trying it are having a period of time of fuel injecting when there is no spark
