13.3 Barometric Pressure
The fuel and ignition can be trimmed to allow for changes in barometric pressure as sensed by a
1bar pressure sensor. The ignition trim is defined in the Baro Ign Trim table. The fuel trim values
are a known mathematical equation so are inbuilt and are non-adjustable.
13.4 Individual Fuel Output Trims
Each fuel output can have a percentage trim. This trim happens all of the time under all engine
conditions. This would normally be set to all outputs 0%.
