Post Start Temp Limit

This field sets the temperature at which the post start correction map is either enabled
or disabled. The following field “Above/Below” sets whether the enabled state
corresponds to a temperature above or below the Post Start Temp Limit. The Post
Start correction map will apply correction to the injection times from when the motor
is started to when the engine temperature reaches the Post Start Temp limit.

Post Start Time Limit

This field sets the period of time across which the Post-start map is to operate.

Staging Bar Number

This field sets the point at which the staged injectors are enabled. If the injection
mode is not "Staged Injection" then this field will not affect injection.

Zero Throttle Map

This feature allows the user to adjust a special fuel map that is used only when the
throttle is closed. This feature should be used for engines that produce constant
vacuum while cruising but irregular vacuum when idling. The zero-throttle Map can
allow simple adjustment of the idle fuel settings. This field enables or disables the use
of this map.


Throttle Pump Dead-band

This field defines the percentage change in throttle position that must occur before the
throttle pump is activated. This feature allows for “jitter” in the throttle that would
otherwise over-fuel the engine. The valid range of values is 1-20%.

Full Throttle Map

This feature allows the user to adjust a special fuel map that is used only when the
throttle is wide open on normally aspirated engines. With some manifold and or
throttle designs, pressures in the manifold can reach close to atmospheric pressure
before full throttle is applied. This effect can make tuning difficult around full
throttle. This map allows the full load settings to be easily set without interfering with
lighter load settings. This field enables or disables the use of this map.

Full Throttle Threshold

This field defines the throttle position at which the ECU considers to be full throttle.
This field can be set between 70 and 100.


Barometric Lock

This field allows the user to base the barometric corrections on a single point in the
barometric correction map. This function is used rather than using the barometric
pressure sensor in the ECU if the spare A/D is required for another purpose. The ECU
now requires the user to provide a barometric pressure value for performing
barometric corrections. This value is programmed via Barometric Pressure Lock at
xxxx (mBars)
.
