The AEM Uego has two outputs. One is the blue serial output that many are creating cables for data logging. The other is a white 0-5v out for auxiliary units.

Is there any way to use this 0-5v wire to log data with EvoScan?

Let me be more specific. I am building a JAW. aka: Just Another Wideband. (http://www.14point7.com/JAW/JAW.htm) The unit is capable of outputting up to two Vout. You can program them to output a 0-5v (much like the AEM Uego)on a scale(refer to picture). I would like to log date from the unit with EvoScan. Does anyone have any input on this?

The ECU is expecting narrowband input from an O2 sensor, from 0v to 1v

You may be able to adjust the ouput of the JAW from 0v to 1v for 0.00 Lambda to 1.00 Lambda, and then do the conversion to AFR in EvoScan. I have no idea what effect this would have on the ECU... I assume it will throw a code.

Although I'm not sure how accurate it will be with such a small voltage range. Also, you won't be able to read over 1.0 lambda (14.7 AFR)

It may also be possible to just output 0v to 5v and just tell the ECU's rear O2 tests to take a hike... this is all guesswork for me though, I don't know enough about the ECU to say one way or the other
