Product Information

Full details

This AEM Electronics Water/Methanol Standard Controller Kit is designed for forced induction petrol vehicles up to 35 PSI of boost, offering enhanced engine performance and protection by reducing inlet air temperatures and preventing knock. While it provides robust control and safety features like 'Boost Safe', users must ensure proper system integration and fluid levels to prevent potential engine damage.

Extended Product Information

FAQs

What is the maximum boost this controller can handle?

The Standard Boost Dependent controller is designed for applications up to 35 PSI of boost.

What does the 'Boost Safe' feature do?

The 'Boost Safe' feature monitors the water/methanol system for errors and can trigger a ground signal. This allows you to implement a failsafe strategy, such as activating a warning light or reducing engine boost/timing, to protect your engine.

Can I use this controller with a diesel engine?

This specific Standard Boost Dependent controller is intended for petrol engines. For diesel applications, especially those exceeding 40 PSI boost, the AEM Multi-Input controller is recommended.

How often do I need to refill the water/methanol tank?

The interval between tank refills varies significantly based on installation, tank size, engine horsepower, and how aggressively the system is used. There is no fixed schedule; regular checks are necessary.

What is included in the kit?

The kit includes the water/methanol controller unit and a color-coded wiring harness with a positive-lock connector.

Can this controller be used for naturally aspirated (NA) engines?

This controller is designed for boost-dependent applications. For naturally aspirated engines, the AEM Multi-Input controller is a more suitable option as it can use other reference signals for progressive injection.

How do I set the boost activation point?

The controller features a large, easy-to-turn knob with clear numbering. Simply turn the knob to the desired boost pressure at which you want the water/methanol injection to begin.

Troubleshooting

Controller not activating

Verify boost pressure is reaching the controller's MAP sensor and exceeding the set activation point. Check wiring connections for the boost source and controller power.

Water/methanol pump not running

Ensure the pump is correctly wired to the controller's pump output and has a proper ground. Check the fuse for the pump circuit. Verify the controller is receiving a signal to activate.

'Boost Safe' not engaging when expected

Confirm the 'Boost Safe' output wire is correctly connected to your failsafe device (e.g., warning light, ECU input). Ensure the failsafe strategy is properly configured to react to a ground signal.

Inaccurate boost reading

Ensure the boost reference hose is securely connected and not kinked. Check for any air leaks in the boost line or at the sensor port.

Pros and Cons

Pros

Reduces intake air temperatures significantly (up to 100 degrees Fahrenheit).
Increases anti-knock index, allowing for higher boost and advanced timing without high-octane fuel.
Provides 'steam-cleaning' effect to reduce carbon deposits.
Includes 'Boost Safe' failsafe for engine protection.
Straightforward installation with provided harness.

Cons

Limited to 35 PSI boost for this specific standard model.
Requires a separate water/methanol tank and pump system.
Effectiveness depends on proper tuning and system maintenance.
'Boost Safe' requires user-defined failsafe strategy implementation.
Run-time between fills varies greatly and is not specified.

Setup, Compatibility & Care

Setup: The kit includes a controller and a color-coded wiring harness. Connect the harness to the controller using the positive-lock connector. Route the power and ground wires appropriately, and connect the boost input hose to the molded-in barbed nipple on the controller. Wire the output for the pump and any optional solenoid as per the wiring legend on the controller. Ensure the boost reference line is connected to a source of manifold pressure *after* the turbocharger but *before* the throttle body.

Compatibility: This Standard Boost Dependent controller is designed for forced induction petrol vehicles with a maximum boost pressure of 35 PSI. It relies on intake air pressure sensing. For applications exceeding 35 PSI or for naturally aspirated vehicles requiring progressive injection, the AEM Multi-Input controller is recommended.

Care: Regularly check the water/methanol fluid level in the tank. Inspect all hoses and connections for leaks or damage. Keep the controller clean and dry, avoiding excessive moisture. The controller housing is splash-resistant, but the unit should not be submerged. Periodically test the 'Boost Safe' functionality by simulating an error condition (if possible with your setup) to ensure the failsafe engages.
