is there anyway i can run my b16 on one o2, my homeboy used to have a b16 in a crx and i remember he only had 1 o2 thats but i dont remember how it was set up if anyone knows how to eliminate a sensor please let me know... thx in advance

 

 

Nooooo it runs like absolute **** like that, trust me I know, thats how my B16A was when I got it... For OBD-0 PR3/PW0 you need to run two O2s.

Wait what is that picture even from? OBD-0 definately uses 1 wire O2s lol...
Oh wait I get it that's showing a neat way to wire up the 4 wire O2 for an obd-1 swap...
No nevermind I still don't get it... anyhow yeah don't do that...

yeah you'll need to run 2. it'll run with one but not good

 

yep ones for cylinder 1 and 4 and the other is for 2 and 3 so if you have them hooked up together your gonna have 2 o2 for 1 and 4 or 2 o2 for 2 and 3 depending on how you hook it up....

 

yes you can do it. you need to socket your ecu and chip it with BRE and disable the o2

X2 agreed.

 

Well, mine ran fine with PR3 obd0 ecu...then I had it socketted for hondata stage 2 after 6 mos..

 

well i got headers that i dont wanna drill into it, what would happen if i drill into the exhaust line and put em next to eachother on the same pipe?

 

PR3 is the integra ecu = 1 o2 sensor

PW0 is the civic/crx ecu = 2 o2 sensor.

I never had a problem running a PR3 with 1 o2, but always had to run 2 with a PW0. don't ask why honda did it that way. they do weird things from time to time. e.i. 88-91 wire harness' compared to 92+ wire harness'

 

haha my mistake negate what i said on top. just looked at my 2 ecu's.... my Pr3 is obd1

i forgot i converted to obd1 a while back

 

^^ I was about to say lol my PR3 definately runs 2 O2s

You gotta drill into it with cylinders 1 and 4 for one O2 and cylinders 2 and 3 for the other O2, i.e. if you got a 4-1 header you're screwed. It adjusts the mixture for each pair of cylinders so you have to have it done properly so it sees what it needs to see, otherwise when it tries to correct it gets all confused.

 

no its a 4-2-1 ok wut tool or drill bit what do i buy to make the holes for it like is there an o2 nstallation kit

 

Just pick up a pair of O2 Bungs and take it somewhere to have them welded in. Alot of O2 bungs also come with a Plug to put in it, so later on if you convert to OBD-1 or chip your ecu to use one O2 you could use the downstream O2 bung and plug the other two.
Any place that does any exhaust work will be able to take care of it. They may even have the bungs.

 

ok drilled put them in one on 1,4 and one on 2,3 the car still runs a little shitty at idle and throws MAP code now after i punch it

 

Did you try switching them back and forth to see which way it runs better? I forget which pin goes to which pair of cylinders. Unless you messed up the wiring somehow the Map code is a totally seperate issue that would cause your car not to run right.

 

no i know the map code it totally different but i matched the o2's how they were exactly on the old manifold but with the bungs it sits a little higher i thought maybe its not getting the reading that it should

 

?

 

As long as they are in the right pipes they should be fine. Have you fixed the MAP problem yet?

 

i messed with my VAFC a little bit and its a lil better now
its funny you know all i did was put blox intake manifold, aem fuel rail, msd ignition,headers and 66mm throttle body. now its running lke **** at idle t
