Power shift can be configured in various different options, it's simplest form is a single cut time. With use of 'complete on target gear', this allows the ECU to vary the cut time to lengthen or shorten it depending on how long the gear change takes. This time can vary dramatically depending on conditions (requires gear position sensor input). Powershift now has the option to either cut the spark, retard the spark or a combination of the two depending user requirements.There is an option for 'cut when pin low', this normally for use with external devices. Also there are many safety features built in, such as, lock out timers & continious assert to protect against power shift being triggered accidentally.
