- **Control Algorithm:** The load source that will be used for the fuel table
- **Squirts per Engine Cycle:** How many squirts will be performed over the duration of the engine cycle (Eg 720 degrees for a 4 stroke). most engines will not require values greater than 4. For sequential installations, this should be set to 2 with the injector staging set to 'Alternating'(Internally Speeduino will adjust the squirts to 1)
- Note that for 3 and 5 squirts, you must have a cam signal in addition to the crank.

- **MAP Sample Method:** How the MAP sensor readings will be processed:
- **Instantaneous:** Every reading is used as it is taken. Makes for a highly fluctuating signal, but can be useful for testing
- **Cycle Average:** The average sensor reading across 720 crank degrees is used. This is the recommended option for 4 of more cylinders
- **Cycle Minimum:** The lowest value detected across 720 degrees is used. This is the recommended method for less than 4 cylinders or ITBs
