## Overview

The Innovate Motorsports LC-2 Digital Wideband Lambda Controller Kit with Bosch LSU 4.9 O2 Sensor is a cutting-edge, fully digital air/fuel ratio controller designed for professional-grade engine management.

Compact and plug-and-play, it’s the industry standard for precision tuning and real-time engine monitoring.

## Description

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 percent 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 the Modular Tuning System (MTS). Operating ambient temperature: 0° to 140° F (−17.78° to 60° C)

Review: Great product, even better support - I chose this broadband unit mostly because it is in effect the industry standard for aftermarket engine management. It's well known and widely understood and recognized as a quality product. Unboxing matched the quality reputation: the housing, conductors, and connectors all reflect high end kit. Best of all is the tech support. I had two questions about my install that were answered by an actual live person - and a knowledgeable live person, too. I am sold on this company. In the future if I need something and innovate makes it, I'm buying their product.
Review: Works perfectly after DOA sensor replaced. - Purchased for a MegaSquirt 3 install on a 99 Jeep Cherokee. The first sensor arrived DOA but Innovate replaced it quickly. I haven't had any way to confirm the sensor reading but it seems accurate enough from what I can tell. Install was easy, their software is ok but I use TunerStudio for everything so that's not an issue.

### ⭐ Not worth the waste of time and hassle
*by J***. on March 24, 2025*

Never worked out of the box. As soon as I program the module and then try to hook up the O2 sensor it threw a code on the connection. Called up innovate for advice and they said to send it back for warranty. It's been there a week and they said there are three weeks out before they'll get it looked at. I would personally find another solution. If I could get my money back I would
