alright....stock b16 headers have 2 oxygen sensors, just bought DC headers with only 1 oxygen sensor port.......what options to i have to run the engine correctly so it doesnt lean out

thanks....helping out a friend

You sure they have 2 sensors? I installed my DC SS 4-2-1 and I don't remember my stock manifold having 2 sensors. Just the one towards the end of the header where it bolts up to the rest of the exhaust.

MrEg

does the 1st gen have 2 sensors ....i remember reading this in another post about 2 sensors and pinouts on the ecu

2000DX

you said you had a B16A2.....

and the 2 o2 sensors....

1)goes to the header
2)goes to the cat.

MrEg

i just installed a highflow cat that doesnt have a port for the o2 sensor.....anyway i can bypass this.??

2 options.

get an OBDII-I adapter and an OBD1 ecu.

or get this:

hmmm, you sure it's a b16a2? the 1st gen OBD0 b16's actually had 2 oxygen sensors right on the header. If that's what you have and NOT an OBDII b16a2 then ignore my above post. You can convert to OBD1 or just weld in another O2 bung on the header. Remember to hook the right sensor to the correct banks of cylinders otherwise one set will run lean and the other set will run rich.
