Wideband O2 Systems

Know your Air/Fuel Ratio – all the time with Wideband O2 Systems, Accessories & Gauges

The full range of Innovate Motorsports Wideband O2 systems can be found below, or click the images above for accessories and add-on gauges. We’d recommend the Innovate LC-2 or MTX-L for permanent installation, and the Innovate LM-2 if you’ll be tuning multiple cars and need to temporarily install and then easily move your wideband o2 system from car to car.

A gauge is optional, though is highly recommended particularly for forced induction applications where it’s a good idea to keep an eye on your air/fuel ratio even after tuning is complete. It’s a nice ‘safety’ to let you know if anything has changed with your setup that you need to address (clogged injector, etc) that could help you prevent a meltdown! You can, of course, start with a wideband O2 system now and always add a gauge later.
