XUD Cat / Lambda

[adamm306]

Hi guys more noob questions... god forbid when i start fiddling with the pump soon lol

Where is the cat located on the XUD is it in the manifold like the 106's i looked underneath and couldnt see anything only a middlebox

im pretty sure it is catted though as it has a lambda sensor but this isnt plugged in? is this a sign of a decat any negative effect having lambda unplugged?

be nice to me im new

A Xud doesn't have a lambda sensor. And the cat it on the down pipe as you look at it just back from the subframe. Though some early Xuds don't have cats.

Get some pics if you can

Early XUDs don't actually have a cat, but if it does it will be coming out of the subframe area then joining onto the start of the centre pipe.
You'll also find a severe lack of a lambda sensor on an xud cat

1) It doesn't have a lambda
2) If it's a Phase 1 it probably doesn't have a 'cat', some came with a decat out the factory.. but if it does have a cat it'll be engine side after the centre box

EDIT: no replies then 3 at once haha

Its not in the subframe, the cat itself is visible from under the car without looking up inside the subframe area.

Is the car modified? may possibly be an EGT probe?

[adamm306]

no its completely standard dont think the fuel pump or turbo have ever been touched its on a N p1 so it may not have a cat

ill take some pics on my break and report back lol

[adamm306]

heres this thing i was on about took a pic of it and also the connector





and do i have an egr? is it inside the box with the red wires? (read the egr is supposed to be behind the battery)

[bigcheez2k3]

You're looking at the front of the engine, the exhaust comes out the back.

[DarkInferno]

take a few steps back

your 'egr' is your glow plug relay.

[adamm306]

Haha whoops... My bad anyone know what that connector is for though? And cool thanks

[con67]

The first pic is the oil switch and the blank connector could be for aircon clutch

hey guys didnt wanna start another new thread really quick question

was following this vid

http://www.youtube.com/watch?v=X4l5on3_IrA

he doesnt mention when screwing the boost compensator on the bosch if its between 1.5-2.5 screws in or screwed out? which one is it i ended up screwing it in as the max fuel one goes in aswell if its out ill have to go change it lol

---

nevermind sorted it

[adamm306]

Hey guys was adjusting the Bosch earlier screwed it in quite far and ended up having it idle at 2k rpm so turned it down a bit and was idling at 1.8k so turned it down again etc untill it idled correctly is that the right way to do it?

Feels faster now and smokes a little bit but don't know of I'm just feeling a placebo effect lol

Boost gauge comes Monday so can see what's its boosting and adjust to suit...

[DarkInferno]

tur the fuel up... turn the idle down.... till you get more smoke then you want.... then turn the fuel down a bit and set the idle....

the lda should be wound out as much as possible.... the seat for the spring should be wound out slightly (if you want to bother with it)....

[adamm306]

Yeah lda is nice and far out ill try again in the morning and fiddle with the idle thanks for your help I feel a bit clueless

[adamm306]

tried to adjust the idle today but the hot idle screw is in a awkward place to get to how do you guys manage to get to it without removing the pump?
