Aem Wideband Sensor Installing

[scotty nm35]

Thanks for the reply. where exactly should I mount the whide band sensor? 36" from the exhaust lands on the down pipe.

I'm planning on buying a titanium down pipe. would it be a good idea to install the bung on the titanium down pipe?

Ti dump pipe? Why?

I just checked, as I have a Ti bung here. It isn't the correct thread though, too small.

Down pipe, mate. I think they're called "front pipes" in planet Oz. As for dump pipes, I have my eyes in the Tomei products. moreover, I'm interested in the AEM non weld bung now that I know something like that exist.

Alternatively just weld in a bung at the start of the cat. That way you won't touch the front pipes at all.

Can you guys help me figure out the location and degree of the bung on the following ARC pipe?

According to YAJ, it's a 3" Ti de-cat pipe but I don't know enough of the BNR32's exhaust anatomy to figure out if the bung will be in the correct location/position:





The pipe flanges are in different positions from each other but that is normal according to the many other pictures I've seen of that particular pipe.

The only concern I have is if the bung is facing 10degrees (or more) UP in order to meet the requirements of the BOSCH sensor I have.

Is the bung setup to allow my sensor to be at 10degrees?

So, I decided to use the front pipes as the install point:

That solved that problem but now I don't know why my AEM gauge does not activate. Is there an on/off switch...?

I found a solid ground and used the 12V from an 'accessory' wire that connects to the radio. I tried different wires, check with a multimeter but still couldn't get the gauge to turn on. I eventually hooked up my gauge to the car battery to see if the 12Vs from that would activate it...

Is my gauge broken?

[negativecamber]

I'll take mine out of the box and see if it does anything when hooked up the same. I'd think it would need 5v or so to the signal wire to show any reading.

[negativecamber]

But 12v straight to the signal might be too much

[CrimsonLey]

I read the instructions. I'm sure it said "10-18" volts was ok... :-(

[negativecamber]

Have you tried touching the signal wire on the terminal?

[CrimsonLey]

So, I finally got my AEM installed. Turns out that the solder that I had to splice the gauge directly into the corresponding wires. I also had to shave the wires down a little more because the stock solder tips were too thick for proper connection.

BIG thanks for negativecamber so helping me figure it out.

My gauge is working now but what sort of numbers should I be looking for? I went driving for about 15 minutes and the gaue went all over the place: 13.5 to 16.0 (for appx 3-4 seconds)...

(BTW, I've been suspecting that my Mine's VX-ROM needs another tune)

[89CAL]

Went all over the place when at a constant RPM/load? Or just while driving normally (e.g fluctuating load and revs?)

At cruise it will fluctuate a bit but should be fairly constant, This also depends on what computer is in the car

If just driving around normally the gauge will jump around. If you put your foot down you should see the gauge start dropping, usually till it hits about 11-12:1 if it is a tuned computer, if its stock ECU then this number could be lower

If you are getting above 12:1 on full load at high RPM then it may be a bit to lean and need a retune

[negativecamber]

Hey! Good to hear you got it working mate.

[Blackkers]

yeah you really need a datalogger to assess that though.
