EGT Correction

EGT correction is fuel dose correction function used to protect engine from excessively high EGT
by enriching air fuel mixture. Per injector correction can be set by selecting EGT sensors
associated with particular injector. Value of correction can be set up in EGT Correction 2D table.
PARAMETER
Enable correction
Injector N probe

Injectors cal.

Injectors cal. table is used to calibrate injectors dead time as a function of supply voltage. Injectors
take some time, to start delivering fuel, from the beginning of electrical signal. This time is longer
for lower supply voltages and it depends on used injector. Also higher fuel pressure can cause
longer dead time.
In case of using popular injector typesInjectors Wizardcould be used to set up dead time.

Barometric correction

Barometric correction table defines fuel dose correction as a function of barometric pressure. It's
used with ALPHA-N fueling strategy. To activate barometric correction it is necessary to check
Enable Baro Correction in General options.

IAT correction

Fuel dose correction table is used to additional correction of fuel dose in a function of Intake Air
Temperature. It can be used as extra correction independent of fueling strategy calculated air
density correction.
Fuel calculating strategy takes in account changes of air density related to its
temperature. IAT correction is additional function used to implement engine
cooling strategies.
DESCRIPTION
Activates EGT fuel dose correction function
EGT sensor signal responsible for fuel dose correction on injector N.
