    I’m running a 04 3.4 supercharger. I’ve had my scan gauge 2 for almost as long as I’ve owned the truck. I’ve only had the supercharger for 75k miles. I never really got into the X Gauge settings of this device, but stumbled across a video on YouTube this weekend. I decided to look a little further into it and played around with it this afternoon. I’ve got an A/F ratio pid now, without installing a wideband O2! Just blew my mind, I didn’t know it was capable of it. I was wondering what other pids you guys have got to work with the X Gauge commands of the scan gauge?
    I’m running the ISO protocol and this is the command I entered to get air fuel ratio.28E732E8-9608-4C82-9E9F-B273FED04DB5.jpg

    I’m going to try the x gauge commands for the trans temp. I already have a trans temp pid in my list scrolling through. It doesn’t work, so I just figured it wasn’t equipped. I didn’t realize there were several different ways to try and get the same information. I was looking at the Toyota specific commands on the website, and completely overlooked the generic obd II command list under the iso protocol.
