AFR
– If wide band O2 input is used, the unit can automatically disable nitrous operation if the A/F is too lean or too rich. The
“cutoff delay” is the time that the unit will wait until it looks for this A/F ratio. In other words, if you enter .5 seconds, the unit will
wait .5 seconds after activation before it will truly turn the system off due to the target lean condition. This allows the sytsem to
ignore the quick lean spike that typica
lly occurs with the initial “hit”.
5.2 Inputs
Figure 11
If using two stages, you can use either one or two inputs to activate each stage or stages. Input 1 or 2 can activate both stages 1 and
stage 2
or
input 1 and 2 can be used to individually activate stages 1 and 2.
Input #1
– Select from “Disabled”, “ TPS Rising”, “TPS Falling”, “12 v Switch”, or “Ground Switch”. The last two would be a
constant 12v or ground such as from a microswitch. If a TPS is used, select the voltage that activation will occur at. Make sure
you know whether your TPS has a rising (0-5v) or falling (5-0v) voltage pattern. EXAMPLE?
Input #2
– Select from “Disabled”, “ TPS Rising”, “TPS Falling”, “12 v Switch”, or “Ground Switch”. The last two would be a
constant 12v or ground such as from a microswitch. If a TPS is used, select the voltage that activation will occur at. Make sure
you know whether your TPS has a rising (0-5v) or falling (5-0v) voltage pattern.
