Can EFILive and LM-1 work together yet? Can you hook up the LM-1 to a laptop running EFILive and record real time WB with a PID? I keep finding mixed responses to this setup. If not, can it be possible to get a D/A converter and then hook it all to the same laptop? I know that with the DIY WB this combination is possible. I am looking for the most straightforward setup with the least amount of overhead.
Any other combinations are also welcome.
TIA.

1 - Does the LM-1 have a variable output voltage that is an indication of the AFR?, Eg, the Techedge unit has a 0-5V output to indicate AFR to some sort of external device.
2 - Does the LM1 have some sort of serial connector that has the AFR info transmitted on it?.

Couple of options
1) There is a serial output on the LM-1 already enabled. The specs aren't public domain, but Klaus has released them to people that asked. It would be trivial to log this and display the data.
2) The LM-1 itself has 44minutes of internal memory (that can include other data sources to, such as rpm, etc.) - you wouldn't get real time display on the pcm, but you could download it to the pcm after the fact and view it.
3) The LM-1 has a programmable analog (voltage) output - you could
a) Purchase an external a/d converter box (Dataq has one with a api for ~25 bucks)
b) Run this signal into a sensor not being used (rear o2) and log this value directly with your scan tool (essentially using a spare input on the pcm as an a/d converter)
(3)(b) is the only option currently available that will do what you desire, though there is talk of efilive allowing the integration of timestamped data from another source natively.
