Features & Product Details

If you’re adding modifications to your vehicle, and are boosting under a whim how can you know how your engine is running?

    When I bought this gauge i expected quality for the money i paid but i was disappointed. The gauge feels cheap and made of plastic.

    Only issue with this was where mount the sensor. Some sources say up front, AEM says 32" back which would require adding a bung. Went with tuner recommendation up front. Seems to be fine.

    Simple Install 1 year ago

    Like others have said, it's easy to install. It took a little thinking to get it through the firewall, but once I found a spot I liked it was super easy. Next was how to wire it. I've got an 05 sti so I popped off the center dash clock and spliced into the wires there. I did have to look on the forums to find out which wires to use (blue and yellow to AEM red and black to AEM black). That took me all of 5 minutes at most to find. I've got it mounted with a cheap mount temporarily while I tune, I'll find a more permanent solution later. Like others have said, in order to use RomRaider or other open source tuning solutions you will need to build a cable. instructions are easy enough and parts are cheap. It would have been nice if it included the serial cable connector so I could have done the whole thing in one night. 10/10, would buy another if I had another car to put it in.

    Extremely high quality, reads accurate, and is very solid. Easy to read, and the installation takes some brain to figure out how to wire it were none are showing. (If your picky like me) Really happy with it. (:

    QUESTIONS & ANSWERS

    • Q: Cobb DP compatibility   MikeW1779 months ago

      Will this plug into the extra bung on the top of the Cobb DP? Also, any suggestions on getting through the firewall?
      • 0 of 0 people found the following answer helpful

        A:  Yes it would. There are a couple of install videos that I could reference. People have come up with some unique ways on hiding wires.

    • Q: Josh P  vincent446294 years ago

      My question wasn't about fitment. I'm just curious if it can catalog via serial cable out to log A/F to a laptop.
      • 1 of 1 people found the following answer helpful

        A:  This gauge can be used for A/F output to a serial cable/laptop, but the serial cable is not included.

      Is this the AEM wideband that is compatible with romraider and ECU flash to read A/F values?

        A:  We are not able to confirm compatibility as this is a universal product. However, there shouldn't be any issues.
