CANchecked MFD28 Gen2 for BMW 5 Series E34 (Vehicle-Specific)
The CANchecked MFD28 Gen2 replaces the air vent insert with an integrated data display while still allowing airflow past the screen. Designed for straightforward installation; illustrated instructions are available for many variants.
Key Features
- Vehicle-specific integration: Bezel design maintains vent function with airflow past the display.
- CAN Bus data: Reads in-depth vehicle data comparable to manufacturer diagnostic tools.
- Gear display: Via CAN Bus or calculated from speed and RPM.
- Touchscreen control: Page navigation via swipe gestures.
- Custom pages: Build your own layouts, add images, or set a start animation.
- Inputs: Up to 4 analog inputs plus direct ethanol sensor support.
- CAN switching: Use the display as a keypad to send custom CAN messages.
- Configurable alarms: Set warnings (e.g., EGT warning above 900 degrees).
- Logging: Record data to the internal SD card for analysis.
- Performance meter: 0–100, 100–200, and 0–200 timing without additional hardware.
- DTC*: Read/clear errors for engine ECU, transmission, ABS, and all-wheel drive.
- Dimming*: Automatic dimming with the instrument panel.
*Not available on all protocols.
Display Pages & Widgets
- Delivered with predefined sample pages.
- Up to 10 pages supported.
- 20 widget types (e.g., sensor value, analogue pointer, YT diagram, speed bar, round display, vertical/horizontal bar).
- Drag-and-drop positioning; scalable widget sizes.
- Fully adjustable widget colours.
- Up to 64 widgets per page.
Display Setup Software (DSS)
CANchecked DSS is used to customize the display, download and review logs, and use the integrated CAN logger. The integrated TRI Editor lets you configure sensors (CAN Bus or internal), set min/max warning limits, and rename sensors.
Supported ECU Values
The display supports CAN Bus data query (UDS, TP2, manufacturer-specific protocols) as well as K-Line (ISO 9141). It ships with predefined TRI/TRX files; queried sensors vary by engine and can be expanded later if values are missing.
Examples of Available Channels
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 in %, terminal 30 voltage, torque, gear, diesel-specific values.
Scope of Delivery
- MFD28 Gen2 data display integrated in the ventilation insert for LHD vehicles
- Connector A (8-way Molex)
- Connector B (10-way Molex)
- Pre-assembled connection cables (20 cm) for power supply, CAN Bus, analogue inputs, 5V, and sensor ground
- Pins for self-crimping
- Two 1K resistors (pull-up for external NTC sensors)
- Quickstart guide
- USB data cable
- SD card (pre-installed in the display)
- SD card adapter
- Anti-reflection display foil
Connections & Expansion
Four analog inputs support linear 0–5V sensors and NTC sensors. CANchecked in-house sensors are already defined in the TRI/TRX files and only need to be connected:
- AIN1: Temperature sensor (NTC01)
- AIN2: Type K exhaust gas temperature converter (TCC01)
- AIN3: Pressure sensor 0–10 bar (FLP01)
- AIN4: Boost pressure sensor 0–5.5 bar absolute (BST01)
An external 8-LED shift light can be connected; colours and RPM limits are configurable on the display.
An ethanol sensor connects directly to the display; a 10K pull-up resistor between 5V and signal is required. Ethanol content and temperature can be displayed and logged.
Advanced Functions
- Math-Channels: Calculate values by combining sensors.
- User-Table: Create additional channels using 2D or 3D maps.
