I don't understand the issue you are trying to present.

If you have the 20 pin socket, you must use it to access all modules unless you want to pull the binnacle and add wires.
If you have the 16 pin socket only then short pins 7&8 on your adapter to access all modules.

Also, what kind of sampling rates do you see with INPA on an E46? With AutoEnginuity I see ~100-300ms with one sensor, and upwards of 1000ms when reading multiple sensors. The program is supposed to be capable of 1ms, so I assume it is a limitation of the CAN. Yes/no?
The baud rate is 9600 and half duplex.

The data comes in hex in up to 32 byte messages. Throughput is a serious limitation.

Later cars (2007+) went to K-CAN at 100kbaud and 500kbaud for faster firmware updates and messaging.
