How do you get the LM-1 to correspond its AFRs to the vehicle's RPM or throttle position. I ordered mine from http://www.Ka24de.com (quick shipping), and I don't see any wires to connect the unit to the RPM signal or throttle signal?

check out innovates webiste (not sure of the link). they have accessories there. theres a couple extra ports on the LM-1 box to plug in things. not sure if they have what your looking for though

I'll check out their website. Is there away to properly analyze that data without the rpm tag. I'm going to be adjusting the AFR with an SAFC II and their adjustment are in RPM increments.

i use an afc also. not sure what u mean "without the rpm tag," u can still view the afr info on your computer graphically with the software that you get with the lm-1. i believe that its graphed by seconds

Does it use paralell or USB? Any idea what the cpu requirements are?

What I meant by rpm tag was that the afr would be displayed graphically on the computer but at the same time it would reference it not only by seconds but also by what rpm the vehicle was at and or what the throttle position is. On the Lm-1 website it has lines plotted and displayed on a computer. They also have the vehicle's rpm, dwell etc plotted right alongside the afr ratio.

Also how do you use the afc to control the afr if you only know what the ratio is at 10 seconds into the record time as opposed to what rpm the engine is at. I'm not sure if I'm making sense here.

i love widebands. lm-1 is great for anything. Saftey is the number one issue why i like it. You can see whats going on soon enough to save a motor if theres an unfavorable condition.
