inactive until boost pressure reaches the
first boost reference value (B1), at which
value first injection nozzle (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) per-
centage, 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 reach-
es 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 injec-
tion 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 contin-
ue to spray while flow rate increases (with
increasing pump duty cycle) until throttle
opening reaches the second throttle refer-
ence 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 per-
centage continues to rise. Similarly, for
Double-Shot systems the second injection
nozzle (or second injection nozzle set)
will begin spraying once throttle open-
ing 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 oper-
ating 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 running during
driving conditions.
5.
Drive normally in a minimal traffic
area where you can safely monitor the
injection controller. Once boost pressure
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 reference 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.
Check all connections and check system
setup on injection controller.
6.
Park vehicle in a safe location and
check for any leaks in Water-Methanol
injection system.
System Tuning and
Nozzle Selection
The Straight-Shot and Double-Shot sys-
tems come pre-packaged with several
different nozzle options that cover a
wide range of applications, but some
controller setting optimization may help
dial in your system for your intended
usage.
When configuring for maximum perfor-
mance, the largest kitted nozzles should
be installed. If engine hesitation, misfir-
ing, or early ignition (excessive combus-
