Constant Value Input¶

Overview¶

A Constant Value Input simply outputs a single, fixed number. It has no
sensor — its value never changes on its own, but you can tune it
from the app. Use it as an adjustable constant or threshold that other IO can
reference by alias: a limit fed into a Compare Input, a fixed
operand for a Math / Divide Input, or a calibration
offset used by a map.

Prerequisites & hardware¶

None. This is a logical input with no source inputs — it
stands on its own. You only need somewhere to use it: another input, output or
map that will reference it by alias.

Add it in the app¶

1. Add a new input and choose Constant Value Input as the type.
2. Give it a clear alias (e.g. Shift Pressure Limit).
3. Enter the value.

Settings reference¶

Common settings¶

Constant Value Input also uses the shared setting — alias. See Common IO Settings.

Example — a tunable shift-pressure limit¶

1. Type Constant Value Input, alias Shift Pressure Limit.
2. Set Value to 850 (the limit in your pressure units).
3. In a Compare Input, compare your measured pressure against
   Shift Pressure Limit. To raise the limit later, edit this one value rather
   than every place it is used.

Troubleshooting¶

• The value never updates downstream: confirm the other IO references this
  input by its alias, not a hard-coded number.
• Wrong magnitude: make sure the value is in the same units/scaling the
  consumer expects (e.g. if a map works in tenths, enter 850 for 85.0).
