Octane Learning
After every refuel, your ECU restarts its knock-adaptation cycle and temporarily caps peak boost until it verifies the new fuel's quality. The Octane Learning screen shows where your car is in that cycle. Open it from the Octane Learning widget on Home, or from the Fuel Quality card on the Turbo widget's detail screen.
Availability depends on your vehicle:
Octane learning only appears for vehicles that support it — see the widget list on Home Dashboard.
Learning cycle
The status hero at the top shows one of four phases:
Waiting
No vehicle data yet — connect and drive to establish status.
After a refuel
The ECU needs to relearn the new fuel.
In progress
Adaptation is underway this drive.
Done
Knock learning is complete — full boost is available.
A checklist below the status shows the same cycle as steps (relearn triggered, adaptation stage(s), learned), checking each one off as your car reports it.

Why it isn't always instant
Your car doesn't broadcast the exact moment learning finishes. On vehicles that broadcast ECU progress flags, KDMLink reads those directly, but the final "Learned" confirmation can still lag a drive or two behind. On vehicles that don't broadcast progress at all, KDMLink tracks the cycle from the refuel itself and only confirms completion from the boost behavior of a full-throttle pull.
Confirming with a pull
On vehicles without a broadcast status flag, the screen shows a Verify with a Pull section: on a closed course, one full-throttle pull through the vehicle's verification RPM band (shown on screen) in 3rd or 4th gear. KDMLink reads the boost behavior through that pull to confirm learned vs. still-clamped instantly, and shows the last pull's verdict.
Closed-course only:
Full-throttle verification pulls should only be done somewhere it's legal and safe to do so, like a track or closed course.
