The wiring diagrams for the EMS stinger shows that the lamba sensor recommended is the Bosch Wideband 0258-104-002 , now chasing the part number up from auto shops has shown that it is like 300 bucks 
Is there anywhere I can get this cheaper , or is there an alternative wideband sensor I can use on this computer.

Have you tryed dealing with say a Bosch agent directly , like Petroject etc . Also $300 compared to the high end Autronic wideband is cheap , i think theres is $600-700 from memory .

It appears it is a LSM-11 , 4 wire , lamda readings 0.8-1.6
I guess that will do for the application.
Finally figured where the info was on the bosch aust site , and I have a nice list of suppliers to talk to when I get back from melbourne.

The sensor that DTA use is a Bosch 0 258 104 002 which is one that
Webcon supply to Mountune and Pectel for their logging systems. I
understand that it is quite special in the way it operates and
the original fitment is actually a MAN truck! It features four
wires. Two for the sensor (black=signal, grey=earth), and two for
the heater element inside the sensor. I've yet to determine how the
heater works. It may just be required for starting, to get the sensor
in to its calibrated operating range. I've shortened the leads, as
they were 2M long! I've used an Amphenol water proof connector from
WWW.RSWWW.COM, #246-8436. I've also had to crimp the connectors to
the wires using a special crimp tool, borrowed from work, as the
grey wire from the sensor just would not take any solder. Its as
if its made from steel wire, and not the usual tinned copper wire,
so forget trying to solder any connectors on to this sensor cable.

The sensor has essentially the same output curve as production car
sensors but is specially made for repeatability and low flow over
sensor element. Thus one can replace prod sensor with lsm11 and connect
to both logger/dvm/? and the car ecm as long as device connected is
of high impedance. The NTK can not as output curve is bipolar.
Want even more background: see "Automotive Electronics Handbook" by
Ronald Jurgen. Chapter 6, Exhaust Gas Sensors, is written by
HM Wiedenmann, Bosch GmbH, Lambda Oxygen Sensor Development.

i dont know if running an o2 sensor straight into a stinger/autronic motec or any aftermarket ecu is very accurate
once u get past cruise mode on the throttle
if you want to measure yr mixtures properly from light to full throttle and full load you will need a whole new meter and sensor
and i dont mean the cheap 200 dollar ones
if you want to use it to tune yr car then u need to spend atleast 700 bucks or more on something descent
