I was wondering, when changing injectors is there a way to tell the PFC the new size as well as the old and it does the math for you? Like the E-Manage. Or do you have to go through each box and take out fuel?

 

Yes you can go to the injector screen and you can dviide the old injector size by the new one to get your percentage but remember to also type in the difference in injector ms time delay, otherwise it may not work that great.
