Okay, we got the b16a in, got the ecu plugged in, i have my wires all ran like they are suppose to. we couldnt get the jdm b16a header in because it was to big and the collector doesnt bolt up to my stock exhaust, so now that im using my b16a manifold from my 00si and it only has one o2 bung so i what we did was put one o2 into the bung, ran a wire and plugged it into the stock o2 sensor location thats on the harness, then i went to the plug thats on the ecu and spliced the wire coming off the ecu for the primary o2 sensor and combined the secondary o2 sensor so basicly the o2 is going directly to the ecu and i have spliced it at the wire for the ecu, i have two long flashes like 1 and then another long 1.

also the pressure switch is causing problems, when i hook it up then the car wont start, i get a code 16 wich is for ignition output signal...

im losing my mind on this issue..

 

k dont run 2 o2 sensors as 1. due to different locations voltages are slightly different. and combines voltages w/ screw w/ ecu and make it think everything is out of wack (well it is). run the primary o2 to the primary location on header and ecu like stock. you can just not run the 2nd o2 and deal w/ codes or have ecu chipped to that it doesnt look for the 2nd one.

 

does the length of the wire effect voltage?

because the primary o2 doesnt sit where it did if i was using the jdm header.
the primary is on the down pipe of the header near the cat.

please help and ttt!!!!

Just disconnect both the O2 sensors if you're worried about it. I drove around for quite a while with them both disconnected; don't worry about getting codes from it (when it sets an O2 sensor code all that happens is the ECU stops fine-tuning the fuel maps; nothing else is affected besides maybe emissions).

 

well im misfiring hardcore...

 

That's not an O2 sensor problem... are your spark plug wires touching/crossed? Have you replaced the cap and rotor? How about the ignition timing, has that been checked/set? What octane gas do you have in there?

 

you will run hella rich running no O2 sensors. You can buy a o2 sensor faker for 20 bucks that tells ECu you have 2 of them but you only got one.

 

Not really true... I ran like this for quite a while, no gas smell from the exhaust. The ECU doesn't throw a code except on compression braking; the OBD0 ECUs are THAT bad at figuring out there's no O2s

 

well i just happen to have 87 octane in there becuase i didnt realize how soon i would be doing the swap. i have a new rotor, new plugs, i tried to get a new cap, but they were out of stock. oh well i guess i can wait till tommorow.

 

87 octane? Come back when you've drained the squirrel pee... what the hell did you think would happen? hahahahah....

i guy i talk to on another web board (phatwhippin) has the two o2 sensors spiced togethe.The only problem you should have is it running alittle rich.are you sure its the o2 sensors. also if its a code 21 like you said then its( VTEC Solenoid Valve
defective circuit or unplugged / defective solenoid valve ) .If its a code 20 then its ( Electrical Load Detector
defective circuit or unplugged / defective sensor) . Hope this helps, lata

 

maybe im reading the codes wrong,,

it beeped 2 long beeps and then 2 really fast beeps immeadiatly after

kind of like

beeeeeeeeep beeeeeeeep then beep beep

OK, really. You're worrying about it misfiring. That's not misfire you're hearing, it's knock. The B16A isn't mean to run on anything below 91 octane, and even that is pushing it (I run 94 all the time). 87 octane just isn't going to cut it. I wasn't kidding when I said drain the tank. The cost of a tank of gas isn't nearly the cost of another engine.

Code 22 is the oil pressure switch. OK, let's just write them all down here:

0: ECU
1, 2: Oxygen content
3, 5: MAP sensor
4: Crank angle sensor
6: Coolant temp sensor
7: Throttle angle sensor
8: TDC position sensor
9: #1 Cylinder position sensor
10: Intake air temp sensor
13: Atmospheric pressure
14: EACV
15: Ignition output signal
17: VSS
21: Spool solenoid valve
22: Oil pressure switch
43, 44: Fuel supply system

I hope that helps somewhat. Please, please drain the pee water and put in real gas .

 

so its not misfiring? when i hit the gas it stutters very badly, but if i try to keep a certain rpm then it smoothes out, what is the easiest way to drain the tank, i dont want to syphon a 1/4 a tank of gas!!! now am i reading the codes wrong or not? if its 2 longs, and then 2 fast beeps and that is a code 22 then the o2 code isnt even going off, i think that kind of makes sense becuase usually o2 sensors take about 30 minutes to go off!

do you use aim? msn or icq?

aim= slowpokesi
msn= brandonr_tsp@hotmail.com
icq= 155771791

 

I don't use any of the above, sorry... I'm not much of an internet junkie

If you have an EF, which I'm assuming you do, then look at the back of the gas tank. There's a big 17mm bolt stuck into the tank. As soon as you pull that sucka out, booosh... out comes de gas

 

Goto autozone, pep boys, etc. and get several bottles of octane booster and fuel treatment and dump it in. It'll raise the collective octane, that is if you don't to drain it all out.

well i drained all that **** out, and put in 93, i have a new distributor cap, it sound fine at idle but when u hit the gas its like blalhahlblahhalbhahahh and then vrooooom
once i get above 3 grand it smoothes out, i have no idea at this point, i think the car is running very rich, what do i do now?

 

also, we couldnt leave the ac fan in becuase of clearance issues, now we only have the regular fan hooked up and its not coming on, the thermostat is opening but its not the fan isnt coming on, when i had the other fan (ac fan) still plugged in, it would turn on when i put the ac on, now when i unplug the other fan and just run the fan closest to the battery and push the ac button it comes on.

im going ******* NUTS OVER THIS ****,

 

damn man, sounds like swaps are big pita's! Hopefully youll get it right, and then youll appreciate more. Good luck!
