Throttle Pump Deadband
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. The throttle position at which this Map is used is set by the Full Throttle
Threshold field. The Full Throttle Map can be disabled if not required.
Full Throttle Threshold
See the Full Throttle Map field above for information on this field. This field can be
set between 70 and 100.
Barometric Lock
If you wish to lock the barometric value that is stored by the ECU to a set value and
override the start-up barometric correction, enable this option. Normally, unless you
are using throttle position as a load reference or have another good reason to do so,
leave this option Disabled. Configuring barometric compensation successfully
requires an in depth knowledge of your engine and the environment in which it will be
operating. Chapter 8 [8.5] contains more information on barometric correction and
how it is applied by the E6K.
Barometric Pressure Lock at xxxx (mBars)
Allows you to set the barometric pressure value to which the ECU corrections will be
locked. The default is 1013mBars ( = 1 Atmosphere @ sea level). Again, unless you
have sufficient knowledge about your engine characteristics and the environment it is
operating in, leave this field as it is. Refer to Chapter 8.5 for more information.
Disable Injector Outputs
Allows you turn off all injector outputs. Setting the value to YES will cut all injector
output which allows an easy way to check the trigger when cranking without having to
locate the injector fuse and remove it. Normally this field should be set to NO to allow
the injectors to fire.
See Chapter 3, Engine Identification for information on how to adjust (using the software)
all of the parameters mentioned above.
