I'm selling a used racepak AF-1 air fuel ratio system, NOT the racepak computer. This is a used system removed in excellent working order and replaced with a different O2 system compatible with my upgraded EFI system. The AF-1 includes the controller, VNET connector, 2 used and one brand new Bosch LSU 4.3 O2 sensors. Price for all is $350. Also selling a good used 0-300PSI fuel pressure sensor only. Price for the sensor only is $100. Will sell the AF-1 or the sensor separately.
