HI guys,

Has anyone logged injector duty cycle on a stock or lightly modded NA engine with bolt ons.

What is your max injector duty cycle?

I'm seeing a max of 74% injector duty cycle at full throttle, 7900rpm , ap2 motor with just bolt ons, stock fuel system.

I'm wondering if this is normal or not.

 

That sounds about right.

 

From previous platforms, that's usually around where it lands ~80% IDC on a stock cal.
