hey guys if i run my b16 without the b16 exhaust manifold and with the b18 one(doesnt have second o2) will it run fine besides the code? i am thinking of racing it on saterday and need to know if it'll run fine...thx for the help

 

1st geb B16's are non obd and need a proper signal from both o2 sensors. If throwing a code, youy computer will most likely not go into vtec.
Youy best bet is to weld in another bung into the aftermarket header.

Most likely you will still be able to engage VTEC throwing a code, some codes won't allow VTEC to engane though.


I am running the obd 0 pr3 ECU with only 1 o2 hooked up and I am not throwing any codes at all and seems to be running fine.

 

ok thats awesome because i have a pr3 and ill be hooking up vtec at the track and then once its hooked up then i go racing

When my car was OBD0 I only ran 1 02 and it never threw a code

It will work. It depends on the ECU if it's PR3 or PW0 one or two O2 sensor. If you want, you can wire the two O2's together.

That's probably the fastest way to take care of it but probably not the best. If you can't get another spot for 2nd O2 welded on then go this route.

 

Great, lets go racing when our **** isnt running 100%, this is why people come back "why is my b16 running a 17?" Do it right.

I told you before the car isn't making the power it should because my cams aren't tuned. The o2 seems like it has nothing to do with it. VAFC is on the way.

 

ok got it wired up at the track and ran it, no codes for the second o2, ran a 14.7 with shitty tires...thx for the help
