CANchecked MFD28 Gen2 Vent Display for Porsche 911 (997)
The vehicle-specific MFD28 Gen2 replaces an air vent with an integrated data display while still allowing airflow past the screen. It’s designed for straightforward installation, with illustrated instructions available for most versions.
Key features
- Vehicle-specific bezel design that retains vent airflow
- CAN bus readout with in-depth vehicle data similar to manufacturer diagnostic tools
- Gear display via CAN bus or calculated from speed and RPM
- Touchscreen operation with swipe navigation
- Custom pages, images, and start animation support
- Up to 4 analog inputs plus direct ethanol sensor input
- CAN switching: use the display as a keypad and send custom CAN messages
- Configurable alarms (e.g., warning at exhaust gas temperature above 900°C)
- Data logging to internal SD card
- Integrated performance meter for 0–100, 100–200, and 0–200 measurements (no additional hardware required)
- DTC functions*: read and clear faults for ECU, transmission, ABS, and all-wheel drive
- Automatic dimming with instrument lighting*
Pages and display layouts
- Delivered with predefined sample pages
- Create your own pages (up to 10 pages)
- 20 widget types (e.g., sensor value, analogue pointer, YT diagram, speed bar, round display, vertical/horizontal bar)
- Drag-and-drop positioning and scalable widget sizing
- Fully adjustable widget colours
- Up to 64 widgets per page
Display Setup Software (DSS)
DSS is used to configure and customize the display, download and view log files, and use the integrated CAN logger. The built-in TRI Editor lets you adjust sensor settings (CAN bus or internal), set min/max warning thresholds, and rename sensors.
Supported values
The display supports CAN bus data queries (UDS, TP2, manufacturer-specific protocols) and K-Line (ISO 9141). It ships with predefined TRI/TRX files that define the sensors queried (varies by engine). If values are missing, they can be added later.
Examples of supported data
Temperatures
- Exhaust temperature, coolant temperature, oil temperature, intake temperature, outside temperature, gasoline temperature, DSG temperature
Pressures
- Boost pressure, ambient pressure, fuel pressure (pre-feed pump), rail pressure (actual/target)
Lambda / mixture
- Lambda value, injection time, short-term lambda adjustment, long-term lambda adjustment
Other
- RPM, air mass, vehicle speed, throttle angle, total ignition angle, ignition angle retraction per cylinder, N75 timing (%), terminal 30 voltage, torque, gear, diesel-specific values
Scope of delivery
- MFD28 Gen2 data display integrated in the ventilation insert (RHD vehicles)
- Vehicle-specific connection cable
- Quickstart guide
- USB data cable
- SD card (pre-installed in the display)
- SD card adapter
- Display foil (anti-reflection)
Connections and expansion
Four analog inputs support linear 0–5V and NTC sensors. CANchecked sensors are stored in the TRI/TRX files by default and only need to be connected.
- AIN1: Temperature sensor (NTC01)
- AIN2: Type K exhaust gas temperature transducer (TCC01)
- AIN3: Pressure sensor 0–10 bar (FLP01)
- AIN4: Boost pressure sensor 0–5.5 bar absolute (BST01)
A pre-assembled AIN wiring harness can be used for connection. An external 8-LED shift light can also be connected, with colours and thresholds configured on the display.
An ethanol sensor connects directly to the display; a 10K pull-up resistor between 5V and the signal is required to view and log ethanol content and temperature.
Advanced functions
Math-Channels allow calculated sensors from existing channels. User-Table enables additional sensors using 2D or 3D maps.
Optional accessories
- CC24000 SLM08 – external switching lightning module
- CC22780 ANC04 – four-way AIN harness
- CC22100 CBD08 – eight-way CAN distribution hub
- CC22902 NTC01 – temperature sensor for liquids (1/8" NPT)
- CC22903 TCC01 – type K converter (0–1250°C)
- CC22901 FLP01 – pressure sensor 0–10 bar (145 psi) M10x1
- CC22900 BST01 – boost pressure sensor 0–5.5 bar absolute (80 psi)
*Not available on all protocols.
