Default Hp tuners and cheap wideband possible option?

So I was wondering if anybody would know if this would work or not. So hp tuners uses a 0-5v input for the wideband sensor and if you are trying to go on the cheap who needs a gauge? I found this part in summit http://www.summitracing.com/parts/inn-3737. Part #inn3737. Its the wideband sensor with the cable connector. Now in the description it says the output is 0-5v so whats to stop me from wiring the 0-5v output straight to hptuners?

You need a wideband controller still, thats just the sensor. It wont work without a controller.

Ahh ok thats what I was afraid of. So the 0-5v output is deceptive haha. Thanks for the input.

In a wideband the PCM/Controller sends a reference voltage to the sensor over 2 wires to "activate" it. It then monitors the current flow across two signal wires - the more free oxygen, the higher the current, but the current is tiny, just 0-3 milliamps or so.
A fifth wire is used as the heater which will use a common ground or the 6th wire as ground.

In short you really do need an electronic controller and cannot just "patch it in".

For cheap, you might look into the "NAW7S" which is
a bare bones wideband ("Not Another Wideband")
which does produce the voltage mode output you are
looking for. I bought one meaning to do a permanent
install, it's still on the shelf.

I bought an AEM wideband on Amazon for 150$. It works fairly well and I have it running the signal through my EGR wire.

Yeah I have hptuners pro. I guess I'll just buy the whole wideband seems to be the easiest most reliable way. Just thought I may have stumbled upon something there haha.
