Can someone explain the timing tables to me. -45 to 45 on base timing. And -45 to 45 on timing after main pulse. Let's say for example there is a 10 in both cells. Does that mean the pilot gets injected 10btdc and then 10 degrees later the main pulse gets injected. Which would mean main pulse gets injected at 0 btdc. For some reason I can get my head wrapped around these. I'm use to gas ignition timing and for some reason the efi live descriptions confuse me
