code if the 40 PSI pump output pressure
switch is not triggered. However, if this
value is set too high, the initial output
pressure spike and injection ‘hit’ can be
too severe and cause the engine to bog
or misfire.
13.
Repeat step 12 to set remain-
ing reference values and accompanying
duty cycle percentage values.
: Straight-Shot systems
have two reference values with
accompanying duty cycle values.
Double-Shot systems have four ref-
erence values with accompanying
duty cycle values.
EXAMPLE: For boosted applications,
your water-methanol injection system
will be inactive until boost pressure
reaches the first boost reference value
(B1), at which value first injection noz-
zle (or nozzle set) will begin to spray
with a volumetric flow rate based on
the first duty cycle value (BDC1). This
injection nozzle (or injection nozzle set)
will continue to spray while flow rate
increases (with increasing pump duty
cycle) until boost pressure reaches the
second boost reference value (B2). At
this value, the pump duty cycle will
equal that of the second duty cycle
(BDC2) percentage, and will remain at
this duty cycle if boost continues to
rise. Similarly, for Double-Shot systems
the second injection nozzle (or second
injection nozzle set) will begin spraying
once boost pressure reaches B3 with a
pump duty cycle equal to BDC3. Flow
rate will increase until boost pressure
reaches B4, at which value the pump
duty cycle will equal that of BDC4.
For non-boosted applications, your
water-methanol injection system will be
inactive until percent throttle opening
reaches the first throttle reference value
(T1), at which value first injection nozzle
(or injection nozzle set) will begin to
spray with a volumetric flow rate based
on the first duty cycle value (TDC1) . This
injection nozzle (or injection nozzle set)
will continue to spray while flow rate
increases (with increasing pump duty
cycle) until throttle opening reaches the
second throttle reference value (T2). At
this value, the pump duty cycle will equal
that of the second duty cycle (TDC2)
percentage, and will remain at this duty
cycle if throttle percentage continues to
rise. Similarly, for Double-Shot systems
the second injection nozzle (or second
injection nozzle set) will begin spraying
once throttle opening reaches T3 with
a pump duty cycle equal to TDC3. Flow
rate will increase until throttle opening
reaches T4, at which value the pump
duty cycle will equal that of TDC4. Note
that DC stays constant past T4 setpoint.
Test Drive
1.
Drain water from windshield washer
fluid reservoir or high capacity tank. Fill
with Banks PowerBlend injection fluid.
2.
Start vehicle and allow it to reach
operating temperature before driving.
3.
Ensure the Water-Methanol injection
system is turned on (see System Setup
and Testing, step 8).
4.
Set injection controller to display
pump duty cycle (see System Setup and
Testing, step 9) to check if pump is run-
ning during driving conditions.
5.
Drive normally in a minimal traffic
area where you can safely monitor the
injection controller. Once boost pres-
sure reaches the first boost reference
point, the injection controller should
display the first pump duty cycle (BDC1).
Pump duty cycle should increase as
boost pressure increases, until boost
pressure reaches the second boost ref-
erence point (B2).
If injection controller only displays zero for
pump duty cycle, the pump is not turning
on. Ensure system is turned on. There
may be an issue with the wiring or setup.
