Thread: Single Injection Event Tune

  1. #1

    Single Injection Event Tune

    Working on a single injection event tune. I have noticed that with the pilot on during cranking the truck holds off the injector opening until 700 rpm. At this point, the pilot comes on then when the ECM sees combustion it turns the main on. With the Pilot completely turned off and cranking to start the ECM turns the main on immediately. I saw 1800Us at 100rpm during cranking. Wondering if someone can point me in the right direction for getting the ECM to hold off on injection until higher RPMs during cranking. Also, would I just need to rescale the main pulse width table to lower this 1800us to 600us? Any advice would greatly be appriciated.

    What year? No to the rescaling of the main duration table. Crank mode uses different fuel tables and parameters than run mode
