I will be needing a wide band to help tune my stand alone soon..



WHat wide-band are you using? Which ones do you suggest? I have been looking at the PLX

How many of you would like to have one..



Should we see if we can get a group-buy going?

I personally use the TechEdge WBO2 unit. I hand assembled mine and it works great. I'd highly recommend it to anybody wanting one. Furthermore it has built-in logging capability of up to three thermocouples, rpm, and I think three or four other channels so if you want to log stuff your EMS doesn't see or you want to log additional thermocouple temps, its the way to go. Plus it works with the less expensive but just as accurate as anything else Bosch LSU4 7057 UEGO sensors (~$30 from 1stVWParts as linked from http://www.wbo2.com, which is what I bought). For that price you can practically buy a brand new wbo2 sensor every year and not worry about busting it.

So i assume i can use one of the 0-5v data logging out-puts as a signal to my standalone???

DigitalSynthesis

Well the logging output is digital for logging to a PC... for reading the O2 data the unit has a WB raw output (voltage proportional to the IP sense current) a WB linear (I think 0-5V) and a simulated narrowband (much more accurate of course, but still with the wierd "S" curve) output ... use the one that works best with your ECU. All of them operate in real time, and at the speed and accuracy of the wideband sensor. They just have different transfer curves based on the properties of the sensor they are simulating.
