PWM.... stands for......?? Pulse Width Modulated? or Modulation? I've always wondered for sure what the acronym meant in EFI.... can someone clean that up for me? As per Matts post - i'm curious... on my truck with my tires, at least from looking at logs, i'm well past 18 MPH while still in first gear.... would this still try to lock up being in first gear or would it still wait until 2nd gear and then try?
