NITROUS LOG SOFTWARE REAL
TIME DATA DISPLAY
After Nitrous Log is launched, the main screen
appears blank. When launched for the first time, the
program uses COM1 as the default port. In most
cases, you will have configured the nitrous controller
USB interface to use a different COM port, such as
COM5. Use the Port Setup command on the
Communications menu to select the correct COM port.
The program will remember the new port setup.
When the engine is running, you can display real
time engine data on an instrument panel type screen
by using the View Real Time Data command on the
View menu. Please note that real time engine data
cannot be directly saved by means of the Nitrous Log
program. However, this data is constantly being logged
when the nitrous controller is armed and can be
downloaded (for example at the end of series of dyno
runs).
Real time engine data is displayed on an
instrument panel type layout with round tach and
speedometer gauges and bar graph type gauges for
most other parameters. Status messages are
displayed in a separate window. If the engine is not
running most values will appear as zero.
Displayed parameters include:
RPM – engine crankshaft RPM (numeric value
displayed beneath gauge)
VSS – vehicle speed in MPH (numeric value
displayed beneath gauge)
TPS – throttle position (0 to 100% or 0 to 5V)
AFR 1, AFR 2 – if you have connected a single or
dual channel wide-band system to the analog
inputs (refer to Figure 5), the software can display
the air/fuel ratio
INPUT 1, INPUT 2 – analog voltage (0 to 5V) on
the nitrous controller analog inputs
BAT – battery voltage
INPUTS – status of the nitrous controller inputs.
Note that the GPIO is active low. The GPIO status
indicator will illuminate whenever the GPIO is
grounded
OUTPUTS – status of the nitrous controller
outputs. Stage indicators will illuminate when all
trigger conditions are met. Note that all outputs
are active low (switched to ground when on)
STAGE1 PWM, STAGE2 PWM – percent PWM.
STATUS – general nitrous controller status
