Open the LapBrain menu and choose Setup profiles under Garage. Find your bike and choose New profile… to record the tires and pressures you ran. Give the profile a name; the tire fields are optional.
Each tire has its own Pressure condition selector:
- Hot: measured on warmers before riding. This is the default for a new slick tire entry.
- Cold: measured after the tire has cooled to ambient temperature.
Enter the reading in psi using Hot pressure (psi) or Cold pressure (psi). Switching the condition preserves your existing data. A cold-only slick profile still opens Cold.
Choose Save profile when finished. The profile's Applies from date determines which sessions use it. Adding an earlier profile can update the setup context for past sessions; check the date and the displayed affected-session message before saving.
For a pressure change between sessions, choose Quick update on the bike's current profile. It carries over the other setup details and saves a new profile effective now. Changing one reading keeps the other conditions and the opposite tire's readings intact. Clear a reading only when you want to remove it from the new profile.
