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.

I'm not too familiar with the LM-1 apart from reading some info off the website, if you are familiar with it can you please answer these questions -

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.

Yeah, what he said
