This wideband works flawlessly. I chose this unit particularly for its ability to be connected with my ecu via can bus. I will definitely buy another one on my next project.

Excellent product. Easy to install. I like that the wideband pigtail was not installed in the plug to ease firewall pass through. Fired right up with default CAN settings. Only things I wish - if the instructions specifically said we could use both CAN and analog outputs at the same time so I could have the 5v run a dedicated gauge. It also would be amazing if the gauge automatically read RPM over CAN so it wouldn’t turn on unless the engine is running. This would preserve an output had to use to provide ground when the motor is over 300 rpm to not burn up the sensor at KOEO. Other than that, perfection.

I have two on my car. They seem to working correctly and start sending data quickly. Quality connectors. I like that you can easily de-pin the wires you don’t need. Example, I de-pinned the analog wires because I’m using CAN on a MS3PRO PNP for my 99 Cobra. I also like that you can map the controllers for the cylinders it will be reading directly from TunerStudio.
