AEM DIESEL WATER/METHANOL INJECTION SYSTEM ADVANTAGE
Water/methanol injection (WMI) systems reduce air inlet temps
and enhance combustion efficiency on turbo Diesel applications,
which allows an engine to deliver more power with less effort.
Water/methanol injection also offers a host of benefits that
promote engine longevity, including the reduction of carbon
deposits left by a Diesel’s exhaust gas recirculation
(EGR) system. AEM’s Water/Methanol Injection Systems for
turbo Diesel trucks and SUVs utilize the most robust hardware
combined with more advanced features than any other comparably
priced water/methanol injection system.

WATER/METHANOL INJECTION SYSTEMS
Power, Lower Intake Temps & Lower EGTs for Turbo Diesels
Benefits of Water/Methanol Injection for Gas Engines
for Diesels of all Boost Levels
AEM Electronics offers two different water/methanol controller
designs for HD and Diesel trucks.
a Boost Dependent HD Controller (Kit Part #30-3301) and has
an on-board MAP sensor (up to 40 PSI) with a molded in nipple
for a boost hose pickup.
HD controller (Kit Part #30-3351) features a multiple input
design. The Multi-Input controller can be programmed to work
with a 0-5v signal from an external MAP sensor for Diesels
running over 40 PSI of boost, or with a frequency based Injector
Duty Cycle (IDC) signal, frequency-based mass airflow (MAF),
or 0-5v voltage-based MAF signal.
Easy to Use Controllers
The new HD controller designs feature large, turn-resistant
knobs and larger numbering to easily set accurate start and
full activation points, with covered status LED and test buttons
for added splash resistance. A plug is integrated into the
HD controller housings for mating to the redesigned wiring
harness’s positive-lock connector. The Boost Dependent
HD controller housing has a molded-in, barbed nipple to accept
a boost hose (up to 40 PSI) and a wiring legend on the back.
The Multi-Input controller has an easy-to-remove plug covering
the programming dipswitches and a programming legend on the
back for the 0-5v and frequency based settings. Both controller
housings feature an easy to access integrated fuse and molded
The wiring harnesses for AEM’s Water/Methanol Injection
kits are terminated with a positive-lock connector on one end
and have color-coded wires to ease installation. Both the power
and ground wires for the pump are included in the harness which
simplifies the wiring process and eliminates any chance of the
pump accidentally activating from a short in the system. An
additional wire is included for adding an optional on/off solenoid
to stop fluid flow when the system is inactive.
Boost Safe Feature
The controllers for AEM’s Water Methanol systems include
an integrated “Boost Safe” output feature that monitors
the entire injection system and triggers a ground signal via
an output if it detects a voltage-related error (short, bad
connection, broken wire, overheated pump, high or low voltage
signal, etc.), allowing users to define their failsafe strategy
from something as simple as flashing a warning light to more
advanced strategies like pulling boost or ignition, or switching
fuel maps on a standalone engine management system. Combined
with the integral and highly accurate conductive low-fluid switch
in the tank, “Boost Safe” can also put your engine
in safe mode before the system runs dry. This exclusive feature
is found only on AEM Water/Methanol Injection Systems.
High Pressure Injection Pump
AEM’s internally-bypassed water/methanol injection pump
does not cycle on an off and provides quiet, smooth operation.
It features robust construction including integral hose fittings,
EPDM seals and a Santoprene diaphragm that provides consistent
and reliable fluid delivery.
5 Gallon Tank
AEM’s Diesel Water/Meth systems are available with or
without a low-profile 5 gallon tank. The 5 Gallon tank includes
a high-tech conductive low fluid level indicator with a positive
lock connector and color matched wires to the wiring harness,
and baffles to reduce fluid slosh.
Billet Injectors and Nozzles
AEM includes two precision-machined billet injectors in its
Diesel Water/Methanol Injection kits that feature an integral
check valve to prevent unintended fluid flow. Three billet injector
nozzles are included for matching water/methanol flow to an
engine’s horsepower output.
Flow Control Strategy for More Linear Fluid Delivery
AEM’s engineers spent extensive time revamping the HD
water/methanol controller’s flow control strategy for
a more linear flow output delivery. This means that the flow
delivery better matches an engine’s need for water/methanol
injection, which further improves charge air cooling and reduces
HD Diesel Water/Methanol Injection System Features:

MAF) controller designs feature large adjustment knobs,

INJECTION ADVANTAGES FOR DIESEL ENGINES:
Reduces Air Inlet
Water/methanol’s “liquid intercooling” effect
on turbo Diesel engines can reduce air charge temps by as
much as 100 degrees, and deliver a more oxygen-rich air charge.
Combustion & Efficiency
In addition to cooling air inlet temps, as the water absorbs
heat in the combustion chamber and converts to steam, the
steam’s expansion rate increases the mean effective
cylinder pressure without causing dangerous pressure spikes.
This effective increase in cylinder pressure combined with
methanol’s promotion of complete combustion allows your
Diesel engine to burn fuel more completely. When fuel is being
burned more completely less is wasted, which can increase
EXHAUST GAS TEMPERATURES (EGTs)
Because Diesel vehicles using water/methanol injection burn
fuel more completely, less un-burnt fuel is present in the
exhaust manifold where it can flash ignite to increase EGTs
and create particulate matter (soot). Water/methanol injection
eliminates this secondary combustion of raw fuel in the exhaust
manifold to reduce EGTs by up to 250 degrees, and reduces
harmful particulates to extend engine life (and that expensive
Safety Notice Regarding Methanol
recommends that users never exceed a 50% methanol concentration
when using any AEM Water Methanol system or component.
All AEM Water/Methanol
injection systems and components (pump, lines, fittings, filter,
flow sensor, tank, and nozzles) are 100% chemically compatible
with methanol. However, for safety reasons we strongly recommend
that users never use more than a 50% methanol concentration
in our systems.
Methanol is a toxic
and highly flammable chemical. 100% Methanol ignites easily
and burns vigorously with an almost undetectable flame. Methanol
can be absorbed through the skin and even small amounts can
cause blindness or even death. Using this fluid at high pressures,
without dilution, in an under-hood environment with nylon
lines and push-to-connect fittings is very unsafe. The performance
advantages of using greater than 50% methanol concentrations
are small, if they exist at all. However, the safety issues
are very real and far outweigh any perceived benefit of running
high concentrations of methanol.
