Logging
The eDash is capable of logging. It will log the minimum and maximum values of all of the sensors
displayed on the Master Dash. To operate this feature, press the Log button at the time you wish to
start the logging function. The Master button will now display the text Logging, indicating that it is
recording all minimum and maximum values that are being shown on the dash. There is no time limit
on logging, as it is only keeping track of minimums and maximums. To stop the logging function,
press the Stop button. The Stop button will now indicate if the minimum or maximum values are being
displayed on the screen. To see the next values press the Min or Max button. To clear the log and
prepare for a new logging session, press the Clear button. The Clear button returns the Master button
and you can now start a new log by pressing the Log button.
DATA LABEL
DESCRIPTION
AFR
Air/Fuel Ratio. The reading from the wideband oxygen sensor.
Air Temp
This is the temperature of the air entering the throttle body.
Battery
Battery voltage.
Boost PSI
Displays the Boost reading in pounds for square inch.
Coolant Temp This is the temperature of the engine.
ESC Rtd
ESC Retard displays the amount of timing in degrees that the XFI is pulling
from the commanded timing value due to knock, if you are using the knock
sensor input.
Fuel PSI
Displays Fuel pressure in PSI, if a fuel pressure sensor is being used on the
pre-setup fuel pressure channel of the XFI.
IAC
Idle Air Control. This is the position of the idle motor. At idle, it will move around
to maintain the target idle speed. Displayed in “counts”. Higher counts mean
the idle motor is open more and allowing more air to bypass the throttle blades.
Its range is from 5 to 180.
Inj DC %
Injector duty cycle. This is a comparison of how long the injectors are open compared
to how much total time is available for them to be open. At higher RPM, there is less
time between injector openings. If this reaches 100%, it means the injectors
physically cannot flow any more fuel. They are already being held wide open.
Lb/Hr
Current total fuel flow rate into the engine. Given in pounds per hour. This can
be used to get a rough approximation of current engine power.
Horsepower = Fuel Flow (lbs/hr) x 2
Load
Calculated Load. A comparison of the current manifold pressure vs. the ambient
atmospheric pressure. Unlike the reading from the MAP sensor – which is affected
by altitude – Load should always be consistent. That is, wide open throttle should
always be around 100% regardless of altitude and ambient atmospheric pressure.
MAP
Manifold Absolute Pressure. This is a measure of the load on the engine. It is
displayed in kPa (kilopascals). With the engine off, this will read around 100
kPa. It will drop down when the engine is started.
MPG
Miles per gallon will be displayed if a speed sensor is being used.
MPH
Miles per hour reading from the XFI, if a speed sensor is being used.
O2 Cor %
Current closed-loop correction based on the reading from the wideband oxygen (O2)
sensor. This is the percent of fuel being added (displays as a positive number) or
removed (displays as a negative number) to achieve the target air/fuel ratio.
Oil PSI
Displays Oil pressure in PSI, if an oil pressure sensor is being used on the pre-
setup oil pressure channel of the XFI
RPM
Engine speed
