Field notes

The described sequence runs from Bluetooth pairing and PCM identification through table editing, datalogging, correction previews, and OBD-II flashing. The page lists support for several OBDLink adapters and names five wideband brands; it also says each save can be rolled back as a version. Android and desktop versions are listed as coming soon rather than presented as currently available.
