The CANchecked digital vent gauge is way more than just a performance meter in your dash. The German company has found a way to tap into the CAN-Bus data stream running throughout the car. Everything the BMW ECU sees is now available on your LCD touchscreen.

The vent gauge takes the place of an A/C-heater vents. It has a pre-installed 3.2" LCD touchscreen* with bright, vivid colors and multiple pages just like a smartphone app. Some advanced-level wiring knowledge is required for installation (see below) but the result is full CAN data at real-time speeds (much better and faster than plugging into the OBD plug). There's also four analog inputs for external sensors. 

Not for cars after 2022. The cars built after 2022 have the updated widescreen / curved display on the dash. While the gauge is still compatible on those cars, the pre-installed vent trim is different and not compatible with the later 2023+ cars. On those cars we recommend buying the gauge WITHOUT the pre-installed vent trim. We're working on a pre-installed solution for the later cars, but do not have them on hand or available at this time.

The amount of data is almost endless. Since almost all of the sensors in the vehicle feed data to the ECU via this CAN-Bus it's all available to you. The screen is customizable in what you show, including colors and graphs and even jpg logos and images. Setup and customization is done via a Windows PC program and USB cable (included). This is like having a standalone racing dash in a convenient and OEM-like installation.

Examples of data available: temperatures, throttle position, brake pressure, air/fuel ratio and Lambda, accelerometer and g-force data, speed, voltages, RPM, gear, and on, and on. It can also read and reset fault codes and measure performance (but not lap times... yet). You can also set alarms for things like temperature or voltage.

The screen comes pre-installed in a new vent for cars with the standard instrument cluster* (not the widescreen). It will take the place of an existing vent but has a small outlet for airflow. While it's more convenient to simply plug into the OBD plug there is less data available and the transfer rate is slower. The best source is from the CAN harness located in the dash. You will need to carefully remove multiple pins from the factory plug and then plug them into new plugs included with your kit. Removing the pins requires a very small screwdriver or de-pinning tools (and patience). Installation is completely reversible.

*This pre-installed version fits the trim for cars without widescreen dash display. This was all cars through the 2022 model year (and some early 2023 that did not get the widescreen). Refer to the photos above with detail on the trim around the gauge.
