Default wide band o2 sensor, is this one cheap...

I found an O2 sensor,

Oxygen Sensor, Bosch LSU 4.2, UEGO, 0.0 to 5.0 Volts, Wide Band

for pretty cheap, vendor name is innovate technology inc.

I was wondering how it would be determined if this sensor was quality or not.

Thanks
-Eric

Innovate makes an excellent wide band meter. The sensor for it, the Bosch LSU 4.2, is also high quality - it's used in some production VWs and Porsches, for example. The sensor itself can be purchased for $38.29 +shipping from 1stVWparts.com.

BTW, you can't just hook that sensor up to your Autometer A/F gauge.

lol, yea i knew that. I have this apexi turbo timer it also displays o2 sensor volts. I figure the only difference was the range of voltage and thought the thing might be able to read it... but i am guessing it wouldnt either. What about using a multimeter ?

seriously though, multimeter?

You can't measure that sensor's signal directly with a multimeter or your turbo timer. That sensor needs to be driven by a special controller/meter. Such controllers can usually be programmed to generate a voltage output that is proportional to the A/F mixture.

Bottom line: You need to buy a wideband meter to use a wideband sensor.

you are still going to need a wideband meter/controller. typically, you run the sensor to the meter/controller unit which correctly operates the sensor. then, you can feed your ECU, gauges, etc., with the appropriate output feed from the meter/controller unit.

so it goes:

sensor -> controller -> ECU/gauges/whatever

PLX 300m or 500m are nice.They have a convertor so you can turn the Autometer narrow band meter into a wideband one as well

If you were on Innovates web site, you probably saw it. The LM-1 package, comes with everything you need (sensor, controller, cables, software, etc). I picked one up for $320 a while back. Good unit and VERY popular in the tuning world.

I've got an Innovate kit, Eric. Works pretty good, but the controller box is pretty large. My only beef is the calibration of the output wires sucks if you're not using the same ground to run the unit as you are to run whatever you're outputting to. Mine was off like 0.1v, and they told me that was normal when using seperate ground locations.

Remember, the Bosch 4.2 wide band O^2 sensor uses a “heat pump” to control the sensor. Basically, a microprocessor sends a PWM (pulse width modulated) signal to the heater element in the sensor attempting to maintain a constant temperature across the sensor element. Also, the sensor output signal is significantly less than your standard O^2 voltages (0.00V to 1.00V I believe).

There is a reason that wide band O^2 controllers cost a bit of money… they are more complex than most people believe. On a personal note, I run the Innovative LM-1 with their data logging setup and haven’t had any complaints.
