  • Setting DwellV3 MicroSquirt® Introduction

    Recall that the dwell is shortened with higher rpm in any cases so increasing the maximum dwell setting doesn t help at higher rpms. For example with a 3.5 millisecond dwell time and a 2.0 maximum spark duration the rpm at which the dwell begins to be reduced is just 2727 rpm on a V8.
