Can anyone recomend a good A/F kit? I was looking to get an independent kit with a 4 wire O2 sensor. Any help would be appreciated.

I just bought a autometer z series a/f guage. Waiting to get it and try it out.

Does it come with Everything or does it run off of the stock sensor?

runs off stock o2 sensor

Go PowerFC. Get a datalogit & tune it with a wideband O2 sensor that you can"rent" to your friends.

I would definitely recommend getting a wide band kit, cost more than an a/f using the stock O2 , but get way better results

but I guess it really depends on what your needs are, if its for tuning, I wouldn't really recommend the units utilizing the stock o2, if you like how the lights flicker back and forth, then go ahead get it, I guess the only other use is it can tell you when your running slightly lean an therefore let you make a slight adjustment and not pop you motor

I say save up and get a real wide band

you can check out www.fjoinc.com , there unit is pretty good price, or there's a diy kit you can get, or if you got lossa cash, MOTEC, Horriba , those units use either ntk or lsu sensors, there are probably other good wb kits out there but these are the one's that come to my mind now

hope this help's your decision

Thanks for all the help guys. I definately didn't need a 5 wire or something of that sort as I don't plan on "tuning on the edge" I just wanted something really accurate that I could use to make minor adjustments with. Like if I noticed I was running a little lean I could compensate(because I prefer the conservative side).

I ended up getting the Tomei set up. It comes with the guage, 4 wire O2 sensor and an amplifier. I got it for a pretty sweet deal. Once again thanks for the info.
