If you don't want to fit permanently Innovate do an exhaust clamp to which you fit the wideband sensor. Works well

Yeah I was just reading the manual...

"7.3 Measuring at the tail-pipe
On non-catalytic converter equipped vehicles it is possible to measure the air-fuel-ratio at the tailpipe.
It is highly recommended to use the optional LM-1 Exhaust Clamp. Without it too much
outside air may enter the exhaust, especially at idle, to prevent correct measurements and
leading to a lean measurement. Sticking the sensor itself into the exhaust pipe can yield
inconsistent results because the sensor will not have outside air available as a reference gas."

So... if I can mount it in the tailpipe... it looks like I can mount it anywhere I like in the exhaust system. If I mount it at the front of the centre box after the Y join then I'll get both banks averaged.

As the bungs are only £2.50 I can afford to put a few in at different positions.

I just spotted this: "Move your sensor bung as far
downstream as possible. Right before the cat, or 2-3 feet from
the end of the tailpipe are good locations."

So - I could put it after the main box if I liked...

Hmm well I think 2 seconds in my exhaust is a few hundred metres behind the car!

I think I'll start with the front of the centre box - there is a nice amount of room, just keep the wires away from the propshaft...... can come up through the gear lever hole maybe...
