Re: How to hook up my LM-1 wideband to my Tweecer?

Yeah, I used to do all that EVP stuff but the DataQ is a much cleaner solution. I had to adjust it's zero though, but after that much better than messing with all that stuff :-)

Uggh, the red and white are BOTH outputs, they are just programmed differently - you can use either because you can easily reprogram the output using the Innovate! LM Programmer software (it's part of the Log Works package). One analog output is setup for 1-2V output for a meter - this is what Calcon wants to see. The other is setup to simulate an O2 sensor so that you can use the wideband as a narrowband input into the ECU. Either can be changed to whatever you want though...

Just as an example, I reprogrammed the output I'm using (I can't remember which wire I'm using as it doesn't matter) to 1-4V out to increase the resolution (make signal more noise immune). I even added an offset to the table voltages to compensate for the ground offset. The LM-1 uses a cable for power and so it's ground get's offset from the true ground at the ECU due to current flow in the cable. More information than you wanted I'm sure...
