Ok i picked up a greddy 4-2-1 1 piece header, i have 2 o2 in my oem header. The greddy one only has 1 at the colecter. Im using a p30 ecu, cant i just use one o2?

Also im throwing a code for my o2 senser heater, does that mean that none of my o2's are working. Since its obd1 not obd0... Cause the pw0 looks for 2, and since i dont have the heater o2 its not finding it?...

So if i just instal the greddy will it run the same?..

there is a way of using just 1 i think...

i got the same header..i took it to a shop and had two bungs installed like stock and plugged the orignal o2 spot. make sure you get the right spots so the sensors will clear the block/head.

also when installing the 1 piece i had to lower/drop the front crossmember.

good luck

 

i know i have to do that, its just im wondering if im actually using one o2. since non of them are heated and im throwing a code for a heated o2..

well if ur runnin a P30 then u should also be running a 4-wire o2 sensor. are u running that one or a single wire o2 sensor?

 

im running a sinlge wire o2, and there is 2 of them....

so if i install the header right it will be fine since im not using the right one? i dont need to get 2 bungs welded in...

And once i get the 4 wire i install it at the colector..

 

ok i unplugged both of my o2 sensors, and my car is running the same. so i guess i can go ahead and install the greddy..

Now my next question, how do i intall the 4 wire o2 with 1 wire plugs... where do the extra wires go..

 

the 4 wire o2 sensor is cake to install. http://mymiata.paladinmicro.com/Miata4-WireO2.htm has wiring info. the guys says he was expecting power gains. you will get none, its a sensor after all

 

wicked! thanks alot... im installing my header today and doing the o2 sensor next weekend..

Thanks

 

header was a bitch to get in, but all in all she's in there.. now i need more info on how to do my o2 sensor..

Like which wires go to where by my ecu..

i have a obd0-obd1 frog harness and im wondering if any go to the extra strad that you see here..

And i notice that my gas milage is really bad, since i have no o2 working..

 

 

TTT

 

TTT?............

 

bahhh, O2 sensors are overrated, haha

 

no man i need gas milage spend 20 bucks a day on gas sucks ***

 

I found this finally after searching for 2 days! With all my reciepts
