air fuel ratio *****
i was driving around with my wide band today.
i have a b16a1 with intake manifold and intake. 2.5 inch exhaust fuel rail, fuel pressure reg. i turned down the fuel psi like 5 psi cause it said i was running rich. but when i go full throttle my ratio is between 10.8 and 11.5 why am i running so rich up hi. i can turn the fuel down more but its already below stock settings???????????????????????????????

You want to keep fuel psi around 40psi at idle, sounds like you need a VAFC and some serious tuning.

My CRX runs about 11.5-12.0 afr at full throttle and it is stock. 10.8 seems a bit rich...maybe an AFC and a bit of tuning with a wideband would be in order.

Right, so Get an AFC and do some tuning!
