Where did you get the downpipe assy?

Looks like a Milltek/JMR job.

Where are you moving the lambda to? Or, are you just repositioning the angle and orientation?

origin unknown i'mafraid.
I bought it from a chap on edition38.
He had it on a mk 2 valver.Its a good fit.Just need to wrap my gear select cables and or manifold itself to help protect them.

Below is taken from the LC1 manual

Do NOT install the Bung below the 3 o'clock or 9 o'clock position.
Condensation can form in the exhaust pipe and permanently damage the sensor.
6 o’clock is the absolute worst position to mount the sensor.

Mine was installed at about the 7 o'clock position,and i am getting intermittent los of o2 signal.It dosn't affect running because i don't run closed loop att but it is annoying and I like to see what is going on.

I ordered a new lc1(spare) a bosch WB sensor and a analogue afr guage on Sunday.
No sign of it yet. Rolling Eyes
anyway.
Lambda probe position moved about 90 degrees.Should be able to get a spanner on it.
Hope so anyway. Smile [You must be registered and logged in to see this image.]

Temp boost return,until i make a better one.
I will be feeding a cylinder head breather back into this aswell via a catch tank.IMO This boost return pipe will always be at atmospheric pressure anyway as it is linked directly to the airbox so no risk of pressurizing the engine.

Looking good with the boost return, you are correct about the boost return line staying below ambient pressure as you are running mega-squirt. On a stock digi ECU the boost return line can have positive pressure dumped into it if the engine goes into a knock condition (boost pressure is restricted to 0.4 bar via the ISV). While I would expect the engine crankcase pressure to be higher most of the time there is a risk of dumping pressure into the block and the only place it can come out is via the oil dipstick or filler cap.

I'm not sure I agree Yan. Smile .What I mean is I would have to measure that sonmehow to believe it.No disrepect.I'm ignorant like that sometimes.
The isv isn't dumping that air into an enclosed space.It's pretty much dumping it to atmosphere as the boost return line just feeds to non presserized side of the charger which is linked directly through to the airbox and the charger will be busy sucking in and re-ingesting that air anyway.I can't see how pressure could ever really build in that pipe.

I guess it makes no difference anyway because i don't have that knock strategy as you say.


are you goingto breath your head yan?
If my engine is anything to go buy you'll need to.Considering getting my rocker cover modified somehow so i can run an air pipe directly to a catch tank.

I don't know on head breathing yet, I am using the 16v block breather hose and a short extension to run into my catch tank so I will need to see how it goes.

If it does start throwing oil around then I have the option of using the restrictor valve connection in the 16v block breather hose to run a line into the boost return side of the charger circuit; this should help to decrease pressures a little more.

As for charger build up in my head you can have some cases where the boost return line is above atmospheric. If you consider a full throttle full RPM situation and then come off the throttle the engine goes from using all boost with a closed boost return to using little boost and an open boost return. This must produce an above atmos pressure in the boost return line for a short period in exactly the same way that closing the boost return line allows for a build up of boost.

P.S. I do have the Beetle block breather on my desk right now, I need to double check the clearance now my front end is back together though.

I guess. Smile fairly mute point as your not going down that road anyway.

I guess it will be good to keep that beetle breather in reserve.Can you post up the part number please?

Sign of a DIY electronic engineer.....breadboard....

Yay for the gauge! Did I really say that??

lol,I have a few of them.
and as i am single now i'll only have more time for struff like that.

Note to self.

"Get a life"

Annoyed about the wideband thing.Ok admittedly I missed the small line of text in the guys ebay shop saying that he was away and wouldn't be back for a few weeks but then when he does send the bits there is stuff missing,messing up my weekend plans.

Ho hum.

Sorry to hear about the singletoness Rob.

I am sat waiting on my new ECU, not paid for it yet but the lead time is approx 2 weeks, as I am currently reluctant to do too much with the car given the overfuelling either it's 2 weeks twiddling my thumbs really.

Don't be sorry,it is all very civilized and mutual.We are both just ready to move on with our lives.

Seems like I have ben sat on my hands for week,today I may as well wire the guage in I guess.

Rob, you know how you seem to love playing with electronics?

Can you knock me up a little circuit that switches an LED on for a few seconds when it first gets power, then goes out?

I can't be bothered to try to fix my ABS. Wink

Annoyed,such a nice day,should be out driving my car.

Anyway might aswell tick off a few jobs.
Afr guage installed.
I also wired up my boost guage lights,Eeek.
Well i did get it from halfords.Razz Will keep my eye out for a nice black VDO boost guage or something similar.

Removed old afr indicator,so will need a interior blank from somewhere.

Question.
Are these VDO guage bulbs available from anywhere?
