The LM-1 is the industry's first and best complete wideband tuning system. A single self-contained unit combines a wideband air/fuel ratio sensor controller, a 6-channel data logger, and an easy-to-read backlit LCD display. The RPM converter is a cable that contains a circuit to convert a tach signal into an analog RPM signal that can be logged by the LM-1. This cable also has 4 additional terminal screws to tap into and log other 0-5 V analog sensors from your vehicle. The unit is brand new in the box. Asking $375. Call 516-484-0655 or e-mail
