Improper use of nitrous oxide systems can result in costly engine damage. Typical naturally aspirated
engine air/fuel ratio targets and timing targets are unsafe for nitrous oxide use. Be sure you understand
the proper configuration of nitrous oxide systems before deciding on these settings.
When the ECU has detected the activation of a nitrous oxide system (by having power applied to the
gray/red “NITROUS INPUT” wire), it will begin using the special settings found on the Nitrous Setup
screen. The closed-loop fuel control will work to maintain the
Nitrous AFR Target . And if the EZ-
EFI
®
is being used to control ignition timing, timing will be locked at the Nitrous Timing Target
value. ( NOTE: This is NOT an amount that timing will be retarded. It is the final timing value the
engine will see.) Learning will also be disabled while the nitrous oxide system is active.
A “Nitrous Signal Detected” LED is provided on this screen. It can be used to verify that the wiring is
properly installed and the ECU has successfully detected the activation signal from the nitrous oxide
system.
EZ-EFI
®
is intended to be used with the same type of “wet” nitrous oxide systems commonly used on
carbureted engines. “Wet” is the type where the majority of the additional fuel required to support the
nitrous oxide is supplied by the nitrous oxide kit itself, as opposed to a “dry” kit where the extra fuel is
supplied by the fuel injection system. While the EZ-EFI
®
system may be capable of supplying all of
the additional fuel needed to support the nitrous oxide, it is not set up to deliver all of that extra fuel
instantly.
An EZ-EFI
®
system used in conjunction with a “wet” kit has a distinct advantage over a carburetor in
that EFI uses its closed-loop fuel control to fine tune the final air/fuel ratio. This can help make up for
a less than perfectly dialed in nitrous oxide system and offers easier tunability and more consistency.
Also, because it is able to alter ignition timing, the EZ-EFI
®
does not need an external timing retard
device.
NOTE: If the EZ-EFI
®
is NOT being used to control ignition timing, it CANNOT provide the reduced
timing typically used with a nitrous oxide system no matter what is entered on this screen. An external
timing retard device will be needed.
