Testing diesel back-leakage with the WPS500X 

Hello and thank you for the feedback. The current clamp is connected around cylinder 1 injector which allows for synchronization with the pulsations between each cylinder 1 injection event. Using the firing order we can ID and attribute each pulsation to the relevant cylinder. Regardless of a misbehaving injector (an injector with poor spill contribution) the electrical event for cylinder 1 remains correct. The blue line in the diagram reveals the injection event (current flow) through cylinder 1 and an induced event for its companion cylinder. The following forum post will help here www.picoauto.com/support/viewtopic.php?p=102275#p102275 I hope this helps, take care....Steve
