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: If no external BARO sensor is wired to the system, MaxxECU will sample MAP during ECU power-on to get a BARO reading, if you are hillclimbing; you might run into unexpected fuel compensations if you are not using a dedicated BARO sensor.
