What model did ya buy? Did ya get the gauge to?

Spartan 2. No gauge have a gauge already and will be connecting wideband  to link ecu 

Prob a dumb question from me but Do I split wires to the gauge or use an ecu analog output to drive the gauge ?

What the maximum you can have these away from engine? Can ya do a temp setup and poke it up the tail pipe? I'd imagine this would not be the most accurate thou? Mixing with the outside air etc

I have a 400mm length of pipe with a sensor that clamps inside the tail pipe. Have used it and seems to correlate well to the usual spot.

Rigged my wideband with 2m extension lead and can be battery/cigarette/hardwired depending on the vehicle.

Cool this is exactly what I was thinking, how do ya deal with the difference size tail pipes? Could ya take a pic for me?

I not super schooled on these sensors but is there any reason why this kit wouldnt do the trick? I'm happy to solder up the leads etc. And I'm picking the read out will save me buying a gauge. It's just to setup a carb on my old holden.

That's the one I've ordered so I'll let you know how I get on. I'm assuming it'll save a gauge etc too

diameter doesn't need to be very big.  I made one from 25mm box as thats what i had hanging around.  the longer it is the better.  as further can jam it up exhaust more likely to get a accurate reading.

Arh so you mean attach sensor to end of small pipe - box and feed up inside tail pipe? Exhaust gases are cool enough here for the wiring? Does it matter which way the sensor sits in the gas flow? Straight in or sideways?

Cheers!

Nah so the sensor stays outside, but the further the start of the pipe is that can extend into it.

The less likely you'll get contaminated readings from fresh air.

Righto that makes sense! Picture says 1000 words! So you want as much test pipe up the tail pipe as possible that makes sense. So the seal into tail pipe is not important. Cheers for the info guys!!

If had a pipe  that fit tight in the tail pipe, would work good.  but yeh obviously  would only work on one sized exhaust.    so getting it right up there is a good compromise.   also only the tip of the sensor needs to be in exhaust flow. so a long boss for the sensor to screw into is good.  can help with sensor overheating/cooling

The wire is in case it falls out, the sensors do not enjoy bouncing along the road and are expensive to replace, this is something I learned the hard way

I bought one of their original kits that came as a bare pcb and components, and it worked well.

I ordered the sigma but got sent the spartan... 

They are sending me a sigma, but annoyed as I wanted the display to see what the carb is doing
