Connecting the Mems 1.6 ECU

Hi

Connecting the Mems 1.6 ECU
I would like to play a bit on the table at home with the spare Mems 1.6 ECU from Rover 1.4mpi 1995.
The problem is how to connect it. I will make the TTL rx, tx, gnd (10, 15, 30pin) interface. Do I also need to connect a 12V power supply to the ECU or is just TTL enough? If not, where to connect which pins.
I know that there will be errors, etc. but I would like to check and experiment with the parameters.
Thanks.

Surely, you have to power up the ECU.

The photo shows the pinouts as labelled on the breakout box I knocked up.

Pins 28 and 29 are the power and ground pins for the ECU, respectively.

Thanks. 

This is exactly what I was missing.
