Enable baro trim
Enable or disabled the built-in pressure sensor (BARO) for small fuel compensation.
Baro fuel trim
Specifies fuel trim in percent based on BARO sensor input.
Note: Without an external BARO sensor, MaxxECU samples MAP at power-on to set barometric pressure. This can cause incorrect fuel compensation during hillclimbs unless a dedicated BARO sensor is used.
Example (MAP not incorporated into the fuel model)
1. The MAP sensor is not part of the VE calculation.
2. Standard BARO fuel trim table should then look like this.
Example (MAP used in the VE calculation)
1. The MAP sensor is part of the VE calculation.
2. BARO correction is usually not required, since MAP already covers barometric changes. However, depending on the engine, a small amount of correction may still be beneficial.
