To hook it up, you run a wire from the tach signal wire on the pcm to the 'RPM' screw. As far as configuring it, I don't know, I was just getting ready to make a post askign about that part 
. At the track tonight mine was thinking I was running 10k rpm for just about the entire run....

i found the rpm pickup worked on my vw's - negative coil discharge. So it might not be looking for a digital ecu signal. or maybe they have two modes or something.
