Chipped ECU vs AFC?

In order to lean out my idle but still provide plenty of fuel for my rest of the powerband I need either a chipped ECU or an AFC...what do you guys suggest and for what reasons?

If you just need to make fuel adjustments a V-AFC, would be a better solution than a ECU. I would only go to a chipped ECU, if I needed to raise the fuel cutoff and or change the ignition timming maps.

From reading the ApexI site on the S-AFC it appears to say that fuel can be adjusted +/- 50% but from 1000+ RPMs.

Does this mean that the idle fuel cant be managed since the car idles at 700 RPMs?
