Best place on my exhaust to mount the lambda?
My Fury is a little unusual as it has a V8 and the exhaust goes under the car and not down the sills. The two banks meet up under the gear box and
then immediately feed into the silencer. I can't figure out the best place to weld the bung in. My concerns are :-
1) Minimising the risk of the sensor getting smacked when I'm driving
2) Making sure it doesn't foul on anything hard or spinning
3) Having reasonable access to actually do the job
I'm not too concerned if I have to mount it on one bank only as my injectors fire into a common manifold which minimises the chances of duff
readings due to a dodgy injector, and if one cylinder is off, the rest should average it.
I've uploaded some photos to Google (http://picasaweb.google.com/dave.g.smith/ExhaustPath#) if you'd care to have a look and
let me know what you think.

Don't know about what position will work in your car, but when I was fitting mine all the documentation said that it should be mounted in the
upper half of the pipe to ensure that any condensate can drain out easily.

I needs to be withing a certain distance of the engine to ensure the gases are hot enough...

Typically a V engine will have a separate sensor for each bank.

Wideband or narrowband lambda?
Wideband have controllers to regulate the heat exactly, so anywhere in the exhaust should be okay, remember sensor needs to be 10 degrees + above
horizontal.

Dave,
I think the Innovate kit i bought (and sent back!) said between 11 and 2 o'clock, about 12" from the head, though it is possible to use an
"Up the Pipe" sensor in the tail pipe.
Do your exhausts share the same silencer? The tail pipe option may be better for you.
The sensor doesnt need the gasses to keep it hot, as it is a heated sensor anyway. If it gets too hot, it will die.
Kindest Regards,
Richard.

One per bank, in combined exhaust flow of all 4 cylinder and as close as possible to the head

was always told as near as the engine as possible and prefferabilily in the vertical leg as to minimise condensation.

Hopefully this will make my issue clearer
My exhaust does 4-2-1 on both sides which meet just before the silencer. Before points 11 & 15 it is pretty much inaccessible. I'm
planning to put it on the backside of the 11->12 branch so that the pipe will offer the sensor some protection from stones and speed bumps. I
realise this isn't ideal, but it is the closest I can easily get to one bank of my engine without too much risk of it getting wiped out within 5
miles of the first time I try to drive it.

for a V8 engine we fit a lambda boss into the collector (where the 4 headers merge into 1)
sometimes one for each side of the engine.
as far as position of the lambda goes. you do not want it pointing straight down. anywhere from 9 o clock round to 3 o clock is fine.
