SSF (Sequential switching function F): Timed sequential switching function F allows the set point values to gradually increase
over time. This switch logic could be applied in a drag racing situation where you want to gradually increase boost levels over a
desired time interval within your elapsed time (ET). The Set point value will increase linearly between the user defined set point
targets, e.g. If SP1 was 20 and SP2 was 50 and the delayed time was 5 seconds, when the timer is started, it would start at SP1
and over 5 seconds, gradually ramp up to SP2
 With SSF active dS1-dS6 will appear in each boost group.
 These time intervals can be entered as the amount of time you want each set point to be active before switching to the next
set point.
 Time delays are in increments of 1/10 th of a second, with the maximum allowable being 99 seconds.
 dS1 refers to the amount of time that it will take SP1 to gradually increase to SP2, dS2 refers to the amount of time that it will
take SP2 to gradually increase to SP3 and so on.
 Earthing the orange wire with a switch will reset the timer and switch to SP1/BG1.
 Earthing the green wire will start the timer at SP1
 The same procedure will happen for all active set points (determined by the nSP parameter in the setup menu)
 Once the last time interval has ended the unit will continue to operate at the final set point.
 To skip a set point/boost group, set the dS parameter for that group to zero.
 This is a solely time based switching method and is not dependant on switching except for the reset to SP1 (earthing the
orange wire) and a GO (earthing the green wire) which will start the timer.
