This shows how to connect the different sensors
The Boost Sensor is attached on KL7 on the MD03 Print
Pins on KL7:
| Pin | Function |
|---|---|
| 1 | 5V |
| 2 | Boost Signal 2 |
| 3 | Boost Signal1 |
| 4 | Ground |
Remember to calibrate your TypK circuit: Build a Kit V2
The thermocouples are connectet to K6 and K7
K7 only supplys ground, so the white wire goes here from the thermocouple.
Pins on K6: (green wire). Pin 1 directs to the VDO connectors.
| Pin | Function |
|---|---|
| 1 | Thermocouple 0 |
| 2 | Thermocouple 1 |
| 3 | Thermocouple 2 |
| 4 | Thermocouple 3 |
| 5 | Thermocouple 4 |
| 6 | Thermocouple 5 |
| 7 | Thermocouple 6 |
| 8 | Thermocouple 7 |
They are connectet to KL9
Pins on KL9:
| Pin | Function for #define VR6_MOTRONIC | Function for #define DIGIFANT |
|---|---|---|
| 1 | Air mass (0-5V) | idle switch (red-blue cable) |
| 2 | RPM (Injector, 12V) | RPM ECU pin 24 out -> dashboard (green-yellow cable) |
| 3 | Throttle (0-5V) | WOT switch (blue-black cable) |
| 4 | Lambda | Lambda |
Lambda can be small band or wideband signal from Innovate LC1 / PLX SM-AFR. Please set the desired define in MultidisplayDefines.h
#define LAMBDA_WIDEBAND
#define LAMBDA_PLX_SMAFR
//#define LAMBDA_PLX_INNOVATE_LC1
They are connected from KL1 to KL6
all have the same Layout:
Pins on KL1-6:
| Pin | Function |
|---|---|
| 1 | Ground |
| 2 | Signal (Resistance against Ground) |
connect it directly to the Seeeduino Mega's pin 49.
connect to K20 Pin 2 K-Line on V2-md01 ( pin 1 is on the left if pcb writings on the pcb are readable )
- digifant 1 ecu: K-Line is on ecu pin 20
connect speed signal to K10 Pin 3 on V2-md01 ( pin 1 is on the left if pcb writings on the pcb are readable )
- VAG cars: use GALA signal blue-white cable
