Well not being synchronized it’s pretty easy… I figure you really meant frequency and duty cycle. Even on new cars that operate on digital timers set in the body controller all the different manufacturers might have slightly different timing they prefer. I don’t believe there is any standard timing required by the EU or USA, etc… So manufacturers will just do whatever they like.
