Looking for advise on pilot injection
I am in the process of trying t build a tune that will work with my (CNG) system that I run on my truck. CNG = (Compressed Natural Gas) . I am trying to disable pilot injection above 1500 rpm so that I am not burning the energy available from the cng that is wasted in the pilot injection. I wanting the injection to take place only in or within the main pulse injection kind of like the older 12 valves with only a single injection event {above 1500 rpms). I have tried to set the pilot injection to 0.00 above 1500 rpms but when I do that I get multiple codes that come up and it runs pretty ruff. Any thought or input appreciated.
