You should have saved the money you spent on the AFC and just got a tune. The AFC is an un-needed piggyback. There are plenty of tuning options for the CA. You could run nisdata, nismotronic(on a s14 sr ecu since they share the same plug but a couple of pins need to be swapped) or just chip your CA ecu and use liveedit to make a .bin. Trying to get the AFC set right without a wideband o2 is a blown motor waiting to happen.
