If you wish to use an external 1 Bar MAP Sensor (left open to atmosphere) in addition to the
one used to measure engine load (if using manifold absolute pressure to measure engine load)
then connect this sensor to the MAP input on the wiring loom and make sure that the Spare
Input function is not set to Baro Sensor. The E6K will automatically recognise the external 1
Bar MAP sensor and no further configuration is required.
Sensing Engine Load via MAP Sensor
The relevant section has been extracted from the main
flowchart and reproduced for clarity. Make sure that the
Barometric Lock has been disabled in the Fuel Set-up
page. The next step is to tell the E6K if you wish to use an
internal or external sensor.
Go to the Input/Output page which is reached using the
hotkey
§N §N §N §N
. Select the Spare Input field and change it to
“Baro Sensor”. When you press enter, a field will appear
below that allows you to select either an internal or
external sensor. Selecting “internal” will use the
barometric pressure sensor located inside the E6K to
provide compensation:
