Innovate DB Gauge ONLY – Blue – 3793



Out of stock


DB Style Gauge to your existing Innovate LC-1 or LM-1, LC-2 or just about any wideband controller.

The DB Series gauges connect to the analog output from your wideband system and provides you with accurate Air/Fuel Ratio information in real-time….. a good idea for high performance naturally aspirated cars, and pretty much a must for forced induction! This is a 52 mm (2 1/16″) gauge that fits many aftermarket gauge pods or can be mounted in the dash.

What else do I need with this?

  • You will need to wire this gauge to an LC-1 or LC-2 wideband system to provide an air/fuel ratio signal. It could be used with an LM-1 or LM-2 as well, although these usually aren’t intended for permanent installation on the vehicle.

Is this gauge compatible with other wideband controllers besides Innovate’s?

  • Possibly. You would need to be able to program your wideband controller to produce the same output voltage signal as Innovate’s.

What voltage signal is it looking for?

  • It needs 0 volts to display 7.35:1 and 5 volts to display 22.39:1.

Does it include mounting hardware?

  • Yes. It includes a “cage” to help fit behind a hole in a flat panel, as well as a small wiring harness.

Will it fit in a gauge cup?

  • This will fit in most gauge pods or cups meant for 52 mm gauges.

Can it work for other fuel than gasoline?

  • It’s really only meant to display gasoline AFRs. You could potentially adjust the wideband’s output curve to get it to display AFRs for fuels with a similar stoichiometric ratio such as diesel or propane, but not ethanol or methanol.
