I had an LM2 and the RPM portion looked like a pain to hook up and I never did. It worked well most of the time as just an 02 monitor. When I started down the EFI road I got rid of it and bought an LC2 which is just a just a monitor. It came with a gauge and the ability to wire it into my EFI. It has worked fine so far, I will probably add another one soon.
