Water/Methanol for High Compression Naturally Aspirated and Forced Induction Gas Engines
AEM offers two different water/methanol controller designs: One is boost dependent (Kit PN 30-3300) for forced induction vehicles up to 35 PSI of boost.
The Boost Dependent controller has an on-board manifold absolute pressure (MAP) sensor with a molded-in nipple for a boost hose pickup. The second controller (Kit PN 30-3350) features a multiple input design that enables users to install AEM's Water/Methanol Injection Kit on both high compression naturally aspirated vehicles (NA) via the MAF/IDC settings and ultra-high boost vehicles (above 35 PSI) using an external MAP sensor.
The Multi Input controller works with an external 0-5v voltage-based external MAP sensor, a frequency based input for Injector Duty Cycle (IDC), frequency-based mass airflow (MAF), or a 0-5v voltage-based MAF.
Robust, Easy to Use Controller Designs
The new 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 controller housing for mating to the redesigned wiring harness's positive-lock connector. The Boost Dependent controller housing has a molded-in, barbed nipple to accept a boost hose 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 mounting tabs.
Boost Safe Feature
These new controllers retain the "Boost Safe" injection failsafe system, which is an output that will activate if there is a short, loss of continuity or high or low voltage or low fluid condition, 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.
Simplified Wiring
The new wiring harness is terminated with a positive-lock connector on one end and has color-coded wires to ease installation. An integrated Pump Ground circuit is 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.
Improved Injector Flow Rate & Nozzle Sizes
AEM's engineers spent extensive time revamping the 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 optimizes charge air cooling and detonation control. Three resized injector nozzles are in each kit and allow for improved flow capability (a flow graph is available on our website).
New Low Level Fluid Indicator
A more accurate, conductive low level fluid sensor is integrated into the tank and features a positive lock connector with color-matched wires to the wiring harness. The sensor eliminates any chance of incorrect readings due to interference from debris.

Manufacturer's Warranty — AEM

Manufacturer's Warranty — AEM
AEM (Advanced Engine Management) warrants to the original consumer that its performance products will be free from defects in material and workmanship for twelve (12) months from the date of the original purchase. Coverage runs to the original purchaser only and is non-transferable, and implied warranties are limited to that same 12-month term. A product that fails within the period is repaired or replaced at AEM's option — that is the sole remedy, it cannot exceed the original purchase price, and AEM disclaims special, incidental and consequential damages. The Bosch LSU wideband UEGO oxygen sensor is a wear item with a limited life and is not covered; AEM lists replacement Bosch sensors under a separate 90-day term. Not covered: improper use or installation, accident, abuse, unauthorized repair or alteration; normal wear and required maintenance; improper handling, storage or lubrication; reversed polarity (+ and - wires crossed); acts of God; and cosmetic damage such as nicks and discoloration. A warranty return needs a valid Return Goods Authorization (RGA/RMA) number, prepaid transportation and a dated proof of purchase, and AEM must receive the product within 30 days of the RGA being issued. AEM requires the installer or end user to contact its tech line before an RGA is issued — do not return a product or request an RGA before that call, since most issues are resolved over the phone. Outside the warranty period, most AEM products other than discontinued items can be replaced at a discounted rate once the faulty unit is documented as field destroyed, again with an RGA issued first.
Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by AEM. Contact us if you need help with a warranty claim.
