Can it show AFR / lambda or intake air temperature?

Not from the standard installation. The display reads the display CANBUS, which is what the Sports Chrono clock is attached to, and those engine values aren’t present on it — they’d be on the drive CANBUS.

Support for adding an OBD-II adapter (OBDLink CX) — which brings in AFR / lambda, intake air temperature, boost and fuel trims — is built and working, and is going through final testing now. It releases in Q3 2026 as a free firmware update.
