The evolution of the world’s most popular stand alone digital wideband 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’s circuitry is self-calibrating, so it compensates automatically for changes in temperature, altitude, and sensor condition.

This Innovate LC-2 wideband system is compatible with all version of MegaSquirt, MS3Pro, and MSPNP ECUs.  It is also compatible with virtually any standalone or datalogger on the market, or it can be used stand alone just for monitoring AFR.  Perfect for racers who need to monitor AFR but do not want a display gauge or already own a gauge or dashboard that can display AFR.

This package includes

  • Innovate LC-2 wideband control unit
  • LSU 4.9 wideband O2 sensor
  • 8 foot sensor cable
  • Weld-on exhaust bung
  • Serial cable
  • Complete manual (Click to download)

The LC-2 features 2 x 0-5v analog outputs, for connection to your Megasquirt or other ECU.  A serial to USB converter may be necessary if you optionally wish to program the LC-2 wideband using Innovate’s LMProgrammer software.  Most modern laptops will require the converter if you wish to reprogram the LC-2 via LMProgrammer.  (click to download)

Replacement LSU4.9 sensor heads are available.

    What fuels can this wideband measure?

    • The LC-2 will support gasoline, ethanol, methanol, diesel fuel, propane, and CNG.
    • Note that the minimum measurable AFR is 0.5 lambda, so the wideband may not be able to measure the extremely rich mixtures required for running methanol on a non-intercooled engine.

    What sensor is included?

    • The wideband package includes a Bosch LSU4.9 sensor.

    Questions & Answers

      Yes. The AFR range stated is for gasoline. Its official operating range for other fuels is 0.5 to 1.5 lambda, although accuracy at the very rich end of that scale may not always be spot on.

      You can use one LC-2 per side, or use a single LC-2 after any exhaust crossovers. You can also just use one LC-2 on one side if two are not in the budget.

      If it's a single turbo, you would only want a single wideband. You can use two if your budget allows - non turbo applications can even run one wideband per cylinder for a max effort tune.
