Thanks Antus. It is a hard slog but I am trying to get something useful out of this exercise, even if it does not get me more horsepower.

Making slow progress with the serial data stream. :comp:

Used USBPcap and wireshark to trace the conversation with the OPCOM interface. Identified MAP, block learn cell and EPROM ID fields so far but need to log more with car running. Only problem with this method is the sheer volume of frames to sort through and assemble into data packets.

Whats inside the opcom interface? There may be serial data available on the pcb which is heaps easyer to comprehend than USB captures.

FTDI and PIC. PIC appears to be ELM like interpreter that talks KW81, KW82 and KWP2000.

I also have a spare ECU and was toying with getting 2 x FTDI TTL interfaces and hooking them direct to the CPU pins.

Yeah you should be able to connect a pair of ftdis up to the tx and rx pins of the ftdi in the opcom interface and log the data that way.

Actually does the device appear as a serial port to the PC? Sudt accessport is a com port monitor which might be a better option to tap in at that layer. http://www.sudt.com/en/ap/

Unluckily not. Comes up as an OPCOM USB device. From memory, VID/PID is 0403/6001. Would also need to debug a lot to see what baud rate on the PC side.

The connector between the engine and the transmission should be located in the centre of the engine bay on top of the trans and is a 5 pin flat connector.
Red/yellow wire goes from Pin D7 of engine ECU to Pin 13 on the Transmission Controller, should be Pin A on the 5 pin connector in the engine bay.
Red/black wire goes from Pin B5 of engine ECU to Pin 25 on the Transmission Controller, should be Pin C on the 5 pin connector in the engine bay.
Green wire goes from Pin C2 of engine ECU and is shared with the instruments and goes to Pin 29 on the Transmission Controller, should be Pin B on the 5 pin connector in the engine bay.

Hope this helps.
Yoda, thanks. They are torque control to ECU, load from ECU and tacho as far as I can discover. Does your diagram show what is connected to D9 of the ECU - this is the only wire unaccounted for now.
