The following buttons are available on most screens:
EXIT
– Exits out of the configuration
Next
– Moves to the next configuration screen
Prev
– Moves back to the previous screen
GoTo
– Allows quick movement to other areas without having to move through all the screens
Areas that are “active” in the touch screen are typically “white boxes” and white “check boxes”. Touching them will either show available
selection options or activate that feature. There may be arrow keys that allow you to view options. Numerical values can be adjusted with
+ and
– keys.
The following is additional information that is different on the LCD than the PC software:
“Set Linear” – The “Set Linear” can be used when defining the nitrous ramp to quickly enter a linear ramp. First enter the start and final
percentages, then select the “Set Linear” button. This will create a linear ramp between the start and final percentages.
Once the initial ramp is made, it can be modified in the following ways:
-
“Smooth” – used to smooth the curve
-
Grab individual points (same as with the PC software) and drag them individually
-
The second graph for a stage is similar to the first, except that it automatically moves through each point, making it easier to
move an exact location
Chapter 7 Hand Held Controller Operation
7.1 Hand Held Controller Operation and Function
The Hand Held Programmer is designed as an aid for programming when the laptop can not be used in a vehicle (laptops are not allowed
in vehicles by many racing sanctioning bodies as well as you usually don’t want a laptop inside a fast race car). It can not create or modify
configuration files, but can do the following:
Allows you load a configuration file from the SD card. This is useful when making a final tune-up decision in the staging lanes
from pre-programmed configuration files
Allows you to datalog a pass to the SD card and view it later on the laptop or PC
Allows you to monitor the following:
o
Engine RPM and MAP Reading
o
Nitrous Pressure
o
Trigger 1 and Trigger 2 voltages
o
# AFR Channels
o
Air/Fuel Ratio’s
o
% Nitrous Activation for each Channel
When the handheld is first opened, it will show the status of the system as indicated by the word “STATUS”. There are 8 digits below that
indicate the following:
The first two letters shown indicate the status Input Trigger #1 and #2. These first two letters could be any of the following:
T
=
Trigger enabled and currently triggered
t
= Trigger enabled but not currently triggered
.
=
Trigger disabled
The third and fourth letters indicate the status of a lean or rich shutoff. These letters could be any of the following:
L
=
Lean cutoff just occurred (which shut the nitrous activation off)
l
=
Lean cutoff enabled, but not activated
. =
Lean or Rich cutoff not enabled
R
=
Rich cutoff just occurred (which shut the nitrous activation off)
r
=
Rich cutoff enabled, but not activated
The last four letters reference nitrous stages 1 though 4. These letters could be any of the following:
A
=
Stage is enabled and is active (All conditions met for activation and solenoid is being triggered)
a
=
Stage is enabled, currently armed, but not active (Input trigger is met, but system is not active due to time or RPM
conditions
so solenoid is not being triggered)
-
=
Stage is enabled, but not armed or active
.
=
Stage is not enabled
