You can not run a Gen 3 24x reluctor engine with a Gen 4 58x ECM. Bad choice for your swap.

How do you plan to do that? A Gen3 PCM won't talk to all the other modules in a Gen4 vehicle. The harnesses are completely different. Nothing interchanges. You have the wrong engine, that's what needs to be changed to make everything work.
