Adaptronic M2000/M6000 to RB25DET pin connector setup

[Alf]

I’m attempting to wire an M6000 (J1 & J2 plugs) into an R33 RB25DET, using the factory engine loom with minimal changes where possible. The ecu is to be used between two cars (street/track) so I’m trying to make it simple to change over.  The R33 is manual. Air con, AFM, EGT & 02 sensor deleted. Don’t intent using the factory consult/OBD either.

I have figured out most of what R33 wires needs to connect to the M6000. Below is a word doc of the matching pinouts and the M6000 pinout diagram.

I have a few questions:

1.   The M6000 has 2 Power Ground connections
•   J2, 8 & J2, 9

The R33 has 7 grounds
•   Pin 10 earth ign signals system
•   Pin 20 earth ign signals system
•   Pin 50 C/U earth
•   Pin 60 C/U earth
•   Pin 107/108/116 Injector ground

What R33 earths connect to the m6000?

2.   R33 Pin 17 Injection Pulse, not sure if this needs to be used.

3.   M6000 has 1 knock sensor input. Can the two factory knock sensors be used? Can the Bosch donut knock sensor be used and is it better than factory?

4.   Using the factory R33 TPS which has 3 connections at the ecu connector. Not sure about where R33 Pin 56 Throttle opening sensor signal connects to, I’ve designated it to J2, 28 TPS 2     Input but it’s labelled as a spare. Not sure where this connection goes to.

5.   R33 Pin 109 Inverse current feedback circuit, not sure if this needs to be used.

An update.

Pin 17 is injector pulse duty output (to trip computer for fuel usage measurement) Not needed.

Pin 31 goes to the consult port (OBD) so it's not needed.

Pin 56 Throttle opening sensor signal connects to the body loom, doesn't connect to TPS directly. It takes the signal from Pin 38 and sends it to the attessa. Obviously not needed here. The thrid TPS connection is signal ground which is sorted.

Pin 109 Inverse current feedback circuit is connected to pin 59 & 49  which are 12V power, Pin 49 connects to ECCS relay. Assuming this wont be needed.

Based on the Adaptronic R33 Select instructions both knock sensors can be wired together.

Still not sure about the earths.
