10. Vehicle speed sensor (VSS) signal. This
connection is required to utilize the full
capabilities of the nitrous controller. Most
vehicles manufactured since 1981 will have a
VSS. Refer to the vehicle wiring diagram for
details. Some late model vehicles with anti-skid
braking (ABS) and electronic stability control
(ECS) systems utilize individual wheel sensors
use to calculate an average vehicle speed.
Accessing a discrete vehicle speed signal on
these systems may not be possible. You may
have to install a driveshaft sensor (contact tech
support for details). For Nissan 350Z
applications, you can access vehicle speed on
the 8P/R signal (pin 26 on the unified meter and
A/C amp module behind the center console).
11. Optional general purpose input/output (GPIO)
signal. Refer to Figure 4 for GPIO hookup
options. If you use the GPIO to drive a shift light,
you must use an 12V LED type. The GPIO
cannot drive a conventional lamp. If you use the
GPIO to retard an aftermarket ignition that
requires a 12V (active high) signal, you must use
a relay as shown. Refer to the Appendix for
recommended relays.
12. Optional analog input signals. The nitrous
controller will log 0-5V data on two analog inputs.
Uses include logging air/fuel ratio from a wide-
band sensor system such as the Daytona
Sensors WEGO IIID shown in Figure 5. The
Nitrous Log software is used to set the units and
scaling for the analog inputs. Refer to the Nitrous
Log section for details.
13. Ground connections. Use 18 AWG wire for the
signal ground and two 14 AWG wires for the
power ground. Keep the ground connections as
short as possible. The ground connections must
go to a chassis ground stud (you can usually find
one under the dash). If you are using the analog
inputs, use the same ground point for any
associated devices in order to avoid signals
errors due to a ground loop.
14. Reconnect the battery ground cable.
