LC-2: Digital Wideband "Lambda" O² Controller (Part # 3877)

The evolution of the world’s most popular stand alone digital O² sensor controller, the Innovate Motorsports LC-2 builds upon the legacy of the LC-1 by adding simplicity and leading edge technology. The LC-2 utilizes the only 100% digital wideband air/fuel ratio technology on the market! The LC-2’s patented award-winning DirectDigital™ signal processing technology provides data on exactly how rich or lean an engine is running at any load. The LC-2’s self-calibrating circuitry also compensates for changes in temperature, altitude, and sensor condition. The LC-2 includes a digital input/output, 2 full-programmable analog outputs, and is ideal for applications such as dynamometers, data acquisition systems, standalone ECUs, and gauges. The LC-2 can also be "daisy-chained" for cost-effective individual cylinder monitoring, and is fully compatible with our Modular Tuning System (MTS). Key features include:


  • Patented DirectDigital™ Wideband Technology
  • Wideband O² Compatible with ALL fuel types
  • Ability to calibrate O² sensor for maximum accuracy
  • Integrated dual-color status LED (Green/Red)
  • *Two configurable linear 0-5v analog outputs
  • Optional sensor cable lengths available: 3ft, 8ft (Included), and 18ft
  • Positive lock connectors for all connections
  • Innovate MTS serial in/out
  • Serial connection to your PC
  • Real-time display data on screen and/or with powerful LogWorks software

*Two fully programmable linear analog outputs to connect to analog gauges, dyno computers, ECUs, piggyback controllers, and other devices with analog inputs. Analog Output #1 (Yellow) is configured as 0 volt = 7.35 AFR and 5 volts = 22.39 AFR; Analog Output #2 (Brown) 1.1 volt = 14 AFR and .1 volt = 15 AFR. With the provided LM Programmer software these analog outputs may also be configured by the user.

Complete user guide and installation manual available online.

Hey guys! Wondering if i was to purchase your innovate LC-2 wideband for my nissan skyline r33, what length cable would be suitable and are you willing to send to Brisbane? Thankyou. Blake.

Hi Blake, we post anywhere in Australia/Nz. The standard cable is 8ft, so depending on where you will be putting it this may suffice, otherwise you would need to purchase the 18ft extension cable as well. If this is the case just ensure you get the correct one, LSU4.9 which goes with all new kits. The LSU4.2 is for old style sensors. Kind Regards Kate

Hi guys, I'm interested in using this kit on a motorcycle (just got a new ecu). The support notes say the bung mush be 24 inches from the exhaust port but that takes it onto my mufflers... can i go closer? Also from the bung (where ever it goes) to the control unit would be about 1 metre, so all the cables in the 8ft kit are way to long. is there an option to make the whole thing shorter? Regards, Peter

Hi Peter Give me a call to order and we can arrange a 3ft cable instead if you like
