I am wondering what others are seeing for there base pulse width on there datalogs for superchargers. I am seeing at my highest rpm's of 5925 a 26 Base PW. If it was a standard pulse width it would be 128% duty cycle. I am using Freescan and i have a thread where Injuneer expains how to figure the numbers below.
