O2 Sensor Help Asap

[Adz2332]

Hey all

Is it possible to wire in a el falcon o2 sensor to run a gtst?

Ive been told yes. But here comes my other problem. I dont have the old o2 sensor to use the plug.

Help!?

The el is 3 wire kit

Aren't you planning to run a wideband with that feedback connected into your ECU?

If so why would you bother with the stock narrowband? I would just delete it all in total.

[Ben C34]

Of course it cam be wired up. As per all the info on here

So if you don't have a plug chop off the loom plug and wire it directly. Or do as John suggested and wait.

[Adz2332]

Just need it for the tune tomorrow. The el plug is white white black and the 33 is see through blue and brown. Which connects to which???

[Ben C34]

There a guide on here somewhere.

And you DONT need it for a tune.

[Adz2332]

Any links ive searched and cant for the life of me find it

[Dose Pipe Sutututu]

Why do you need a narrowband for a tune?

Who's telling you to do it?

[Ben C34]

Screw it into dump pipe to block hole.

Snip off wires

Get tuned

[Adz2332]

My tuner says to do it??

Just easier for me to do it now I have it

[Dose Pipe Sutututu]

Interesting, do as you please

[Ben C34]

Your tuner sounds special!

[Ben C34]

Anyway, the O2 sensor thread is the third sticky in the general maintenance forum. Hidden away at the top of the page

Towards the bottom are the colors.

[Adz2332]

Thanks.

Does it make any difference I dont have air temp sensor or afm?

[Ben C34]

You running a map ecu?

Air temp is crucial to the tune.

[Ben C34]

Sort that out. That's critical. The O2 sensor is easily left out.

[Adz2332]

Ok I may be confused then.

Where and how is that set up? ?

[Dose Pipe Sutututu]

There's a table that lists the temp and the enrichment in both negative and positive.

When the charged air is more cold more fuel required as the air is more dense. Without adding more fuel your combustion will burn leaner and reverse goes for warmer air, it's less dense so you need less fuel.

Very crucial sensor for a MAP car

Very crucial sensor for a MAP car

Absolutely critical would be the way I'd describe it.

And it needs to be a proper, fast acting temp sensor too. Not one of the big heavy lumpy pieces of crap that Nissan installed into RB26s and SR20s.

[Adz2332]

What do I need and how?

[Dose Pipe Sutututu]

Install it after your FMIC however don't install it in the engine bay as it will heat soak.

On the ECU you will need to run a wire from pin 36 to the sensor and another wire from pin 30 (sensor ground) to the intake air temp sensor. Do not ground it off on the chasis, it will read wrong.

Series 2 ECU will have something connected to pin 36 but just chop it. I believe it's the TPS close position which is useless. On a RB26DETT harness it's used also as the IAT
