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 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.

Value The fixed value this input reports — (the value referencing IO expect) sint32 Can be negative. Change it any time to retune the constant; everything referencing this input picks up the new value.

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).
  • Compare Input — compare a signal against a value or constant.
  • Math Input — combine inputs, often with a constant.
