Yup. Understood that. Waiting on some feed back from PC for 919-611 (R1150GS) and 918-611 (R1150RT). It's likely the technology and circuitry for the Wideband Commander and the Powercommander III USB are similar if not the same. But will know more in a day or two.
Can you take a look and see how many wires are in the cable that goes to the Motronic O2 input? Wondering if it is 1 or 2.
One of the things I discovered during my LC-1 project is that the Motronic input is two wire, offset by 140 mV but that it can be driven by a single wire if the voltages are offset.
