Great guide and thanks for taking the time to do it (even though I don't own an LS400).

If I may just be slightly picky, I suggest that you save the document as a PDF file. A DOCX file requires Microsoft Office 2010 or newer to open it and not everyone has that because it has to be bought, whereas Adobe's Acrobat Reader (designed for PDFs) is free and you can almost guarantee that everyone has it.

It is true that the free LibreOffice can be used to open Microsoft Office files but it has been known to cause problems for some.

The exercise was certainly a success as your idling speed should be at 650rpm on the vvti engine and the variables you experienced at various stages up to that was the results of the engine ecu learning the output from the engine after you had cleaned the throttle.
