I am going to use my wideband to tune a friends car. Can I just mount the o2 sensor at the muffler and still get a accurate result? I just need 2-3 pulls to datalog.

On a dyno? or on the street?

Either way you'll probably notice the readings to be a tad leaner than those read 12" or so from the turbo's exit.

Innovate sells the clamps you'll need, but probably isn't recommended for street use. ;)

We were going to do it the ghetto man's way and use a empty warehouse street.

Well.

Do you have enough money for a new sensor?
Nope, but he doesn't have a wideband bung. Might just secure it nicely and then take it for a spin. haha.

Well then bank of ruining the sensor when it goes flying off, then feel lucky when it doesn't! :)

Good luck.

I have been told by a professional dyno tuner that the exhaust is .2 - .3 afr leaner at the tail pipe than the downpipe. Just my 2 cents.

o2 sensor is ignored at WOT. You are only tuning WOT, so it won't matter. Suck it up and hit the gas. The important information will be displayed.

I read a while back that the existing o2 sensor location is too hot and can destroy or distort the readings. Is that true or just a myth?

Definately sounds like a better idea though.

Is it another MKIII you'll be "tuning" ?

How are you going to adapt a screw in sensor to a bolt on?

If you buy a o2 sensor kit from AutoZone, they come with the adapter. :)

No a celica I'll probably just mount it on the exhaust where the silencer goes.

We need to know that part number from autozone or Napa. Do you have it?

I found them when trying to get a new o2 sensor.

The sensors were screw in, but came with the adapter plate.
If you go into AutoZone and ask for a o2 sensor for a 89 supra, he'll bring you the box.

I'm sorry I don't have the part number, as I ended up using my old sensor. :(
