Which wideband do i use? And do i only need the sensor or do i have to buy the complete 200-400 kits? I have found the bosch lsu 5 wire for about $60 among others. Can i just install that according to the instructions, and use the s300 to street tune or do i have to buy one of the whole plx , innovate, aem kits? And if I do which kit is the best? In other words what is the cheapest way to be able to tune my A/F acurately?

You cannot use a sensor alone. We recommend the PLX packages.

Okay is the PLX DM-5 SM=AFR combo a good choice? I like the guage ... Also why would you daisy chain these unit, why would there be a need for more than one?

Any PLX system will work, the choice is up to you.

I was reading up on the auto tune function. Does it only work in open loop?

That is the only time it should be used. We find that the autotune fuction will only get you a rough map to start with, and then you must smooth it out from there.

I have an innovate LC1 with moates.net O-meter package and I love it. All the wiring is done at the ECU and only took like an hour to wire. The o-meter mounts really easy anywhere on the dash. I have the output going to the ELD input on the ECU and s300 autotunes with it. Also, im using the narrowband output, so no need for the factory o2. Heres a link:

heres mine:

Okay I have the plx dm-5 now. I am ready to install but I have a question. My car is a 96 civic ex, with a b18c1, and an OBD1 ecu(obviously). I have two O2 sensors one where the cat used to be, and one about a foot and a half closer to the motor. Is there a way to use the one closer to the motor and keep the one where the cat was, and would that be benificial at all? If so how should I connect it? Thanks for the help.

OBD1 only uses the primary o2 sensor. THe one is the cat is not connected to anything.
