    I have a 1989 4runner running a 5vz out of a tacoma. I have the 2nd gen black S/C and I am running the URD 7th injector kit. My Question is what is a normal A/F ration reading while cruising. I believe I am running lean. Under boost it drops down to 11 on my wideband but is a 14-15 while cruising. I can't figure out why. Any Ideas?

    So turns out my URD controller was wired incorrectly. I found the Directions on what needs to be wired but its for a 2002 tacoma and my motor is out of a 96. So I found the pin configuration and cross referenced them. The only question is. i can not find the Air fuel sensor pin to the ECU. The only ones for my ECU or heated oxygen sensor 1 and 2. Any ideas?

    14.7:1 in closed loop cruising is normal. 11's under boost with some throttle(open loop) good. Not sure why you think you have a problem unless you are trying to tune afrs richer in closed loop/cruising/part throttle.
