you need an afc(or equiv.) and a wideband.

The wideband monitors your AFR ( I have a zeitronix )
The AFC adjusts the amount of air your ecu see's, therefor adusting fuel AND timing.

The AFPR adjusts the pressure at your fuel rail adjusting fuel without modifying timing....

Correct me if i'm wrong
