Product Information

Full details

This AEM Electronics Water/Methanol Injection Kit with HD Controller is designed for forced-induction diesel applications, offering a significant power increase of up to 20% by enabling higher boost pressures and improved combustion efficiency. It effectively lowers inlet air temperatures, suppresses detonation, and reduces EGR-related carbon deposits. A key benefit is its robust HD controller with user-friendly adjustments and a 'Boost Safe' failsafe system for engine protection. However, proper tuning and installation are critical to achieving optimal results and preventing potential issues.

FAQs

What is the optimal water/methanol mixture ratio?

A 50/50 mixture of distilled water and methanol is generally recommended for optimal cooling and detonation suppression.

How often do I need to refill the tank?

Refill frequency depends on usage and the amount of boost. The low fluid sensor will alert you when the level is getting low, typically before it runs completely dry.

Can I use pure methanol or pure water?

While pure methanol offers more cooling, a 50/50 mix provides a balance of cooling and octane-boosting properties. Pure water is primarily for cooling and does not offer the octane enhancement of methanol. Using only pure water might not yield the same performance gains.

What does the 'Boost Safe' feature do?

The 'Boost Safe' feature monitors the water/methanol injection system for faults. If an error is detected (e.g., low fluid, pump failure, wiring issue), it sends a signal that can be used to protect your engine by reducing boost, ignition timing, or activating a warning.

Can this kit be used on gasoline engines?

This specific HD controller is tuned for diesel applications (5-40 PSI boost). AEM offers other controllers and kits designed for gasoline engines with different boost ranges and requirements.

What is the flow rate of the included nozzles?

The kit includes three interchangeable nozzles with flow rates of 250cc/min, 500cc/min, and 1000cc/min.

Is the pump safe to mount in any location?

The pump is waterproof and safe for mounting in locations exposed to the elements, thanks to its robust construction and sealed design.

Troubleshooting

System not injecting fluid

Check fluid level in the tank, ensure the pump is receiving power, and verify all hose connections are secure and not kinked. Inspect the controller for any error indicators.

Low fluid warning light stays on

Ensure the conductive fluid level sensor is properly seated and making contact with the fluid. Clean the sensor contacts if they appear dirty.

Engine power is not increasing as expected

Verify the boost reference line is correctly connected and providing a signal to the controller. Ensure the correct nozzle size is installed for your engine's power level and that the controller's start and full activation points are set appropriately.

'Boost Safe' system not triggering on fault

Confirm the 'Boost Safe' output wire is correctly connected to the intended device (e.g., ECU, warning light) and that the system is receiving proper power and ground. Test connections for continuity.

Pump is noisy or not running

Check the pump's power and ground connections. Ensure there are no blockages in the intake or outlet lines. The pump is designed for quiet operation; unusual noise may indicate an issue.

Pros and Cons

Pros

  • Increases engine power by up to 20%
  • Lowers engine inlet air temperatures significantly
  • Suppresses harmful engine detonation
  • Reduces carbon deposits from EGR systems
  • Provides engine protection with 'Boost Safe' failsafe feature
  • User-friendly controller with easy-to-set activation points

Cons

  • Requires careful installation and tuning for optimal performance
  • Water/methanol fluid needs regular refilling
  • Potential for system errors if not installed correctly
  • Additional components might be needed for advanced failsafe strategies
  • Not suitable for naturally aspirated engines

Setup, Compatibility & Care

Setup: Installation involves mounting the 5-gallon tank, the pump, the HD controller, and the V3 injectors. The system requires connecting the pump to the tank, the controller to the pump and power/ground, and the injectors to the controller via the provided tubing. The boost reference line needs to be connected to the controller, and the 'Boost Safe' output wire can be connected to your engine management system or a warning indicator.

Compatibility: This kit is specifically designed for forced-induction HD and turbo diesel applications with a maximum boost range of 5-40 PSI. Ensure your engine's management system can accommodate potential changes in air/fuel ratios or can utilize the 'Boost Safe' signal for safety.

Care: Regularly check the fluid level in the 5-gallon tank and refill as needed with a 50/50 mix of water and methanol. Inspect all hose connections for leaks. The pump and controller are designed for durability, but it's advisable to keep the controller area relatively clean and dry. Periodically test the 'Boost Safe' system to ensure it functions correctly.
