AFR Nitrous Disable Percentage
This setting determines at what Nitrous Percent (Duty Cycle) the Wideband Disable function is active. When the
progressive ramp first begins the system will not be at 100% nitrous. Use this setting to determine at what
Nitrous Percent the Wideband Nitrous Disable function becomes active.
Example - When the Nitrous is first armed the air-fuel is 12.8 to 1 and the Wideband Disable Voltage is set to
turn off the nitrous if the system is 12 to 1 or above. This setting would allow the Nitrous and fuel to begin
flowing and get to an air-fuel ratio that is below the disable setting.
The Valid Range is 10% to 100% in 1% increments.
