Fuel and ignition revamping (solved?)

Also with the FI it controlled the fans and it would bump up the idle when the fans came on

Then I'm wrong, at least to some extent. If it bumped timing and maybe rpm ? then my assumption that is strong idle doesn't hold up.

Worst case you could install a the idle solenoid like those used on some A/C equiped cars to bump the idle speed up under load.
