The Innovate XD-16 and LC-1+ kit includes an LC-1 wideband controller with 02 sensor, plus, SSI-4 multi sensor interface, XD-16 gauge. The XD-16 features programable LED colors and a remote control button to start and stop log sessions, initiate calibrations or view min/max values. Used in conjunction with LogWorks, this set up allows you to record and analyze 5 channels of data. These channels are Air/Fuel Ratio, and any four of the following: RPM, Injector pulse width, Throttle position, driveshaft/wheel speed or boost/vacuum. The LC-1 is more accurate than conventional designs costing many times as much and it's self calibrating circuitry can compensate for changes in temperature, altitude and sensor condition. Two user programable analog outputs, cost effective indvidual cylinder tuning, easy to upgrade and includes LogWorks software.
