    PI injector limit 3rd gen coyote

    I have been running into a issue where my PI injector duty cycle maxes out at 62% and no matter what i do it will not go any higher. I realize most people will say go bigger injector. But being capped at 62% is just silly.

    There seems to be a PI limit for DC in +2018 tunes, it will try to compensate with pulse width and you end up shooting the fuel on closed valve...

    So far most would just throw bigger injector...
