Element Hydramist Water/Methanol Injection System $799

 

The Element Hydramist was developed from the beginning to be the ultimate water/methanol injection with uncompromised performance, control, and safety.  The Hydramist is a fully integrated water/methanol injection solution controlled via the Hydra EMS. This system allows full 3D mapping of water flow based on load and rpm, automatic map switching, and unparalleled protection never seen before in any water/methanol injection system. When we first set out to develop a water/methanol injection system we discovered very quickly the limitations of most universal systems in that they rarely offered precise control over the injection or the failsafe mechanisms were insufficient at protecting the engine when failure occurred.  To help develop a superior system for the Hydra EMS Element Tuning worked with the industry leader in water/methanol injection systems, Aquamist. 

The biggest problems encountered during development revolved around complex failsafe mechanisms.  The electronics were optimized as this would ultimately make it more reliable.  The Hydramist's primary failsafe criteria are water flow, water level, map switching, and boost. A sensor is placed after the water injector and just before the misting nozzles located in your intake. This turbine sensor sends information to the Hydramist DDS3 gauge and control unit.  The amount of water flow in CCs is displayed on the Hydramist's 52 mm gauge. The system can then be tuned to activate within an acceptable window of water flow. For instance if your pump fails or the nozzles become clogged resulting in a low CC water flow rate, this information will be displayed on the gauge and detected by the failsafe system. If the setup once tuned is designed to flow 350cc of water but the sensors are only reading 150 cc. The low fault (WL) may be set to recognize this as a problem which would then send a signal to the Hydra to revert to the pump gas mapping and drop your boost (optional). Now if water flow is north of the set window (WH) and hits 450cc then this likely a sign a water line is cracked or broken which sends a fault signal to the Hydramist. The gauge will display water flow rate and whether the system is running normally or if there is a fault by illuminating a light (B).

A water level sensor is also utilized which is installed in the water tank that deactivates the system and reverts back to the standard pump gas maps when the water level is too low. This is displayed by illuminating the water level light.  Under all fault conditions the system is shut down to prevent damage to the pump. Also the Hydramist DDS3 has a main power button which allows you to turn the system on and off. The process of turning off the Hydramist DDS3 reverts the Hydra to the standard pump gas maps.

How the Element Hydramist integrates with your Hydra EMS:

 

Element Tuning assigns a 3D PWM Map 11 as your Hydramist HSV (water/meth injection) map.  The HSV is similar to a fuel injector and the Hydra EMS controls this HSV to inject a certain amount of water via a 3D PWM Map.  This map is load vs. RPM and the values denote duty cycle of the HSV for a given boost and rpm. The load and rpm sites are 0% to 100% and signify the minimum and maximum range in your fuel map. So if the greatest boost level in your fuel and spark maps are 31 PSI then the 100% load site = 31 psi. Element Tuning customers can be provided with this map.



When a boost and rpm level is reached in this map and the HSV has a duty cycle higher than 10% this will automatically activate the Hydramist pump. If within 2 seconds the Hydramist Water Flow sensor does not register water flow on the Hydramist DDS3 gauge the system will automatically revert back to the regular fuel and spark maps in the Hydra EMS.

While the Hydramist is active, fueling is controlled by the Fuel Auxiliary Trim Map. This map is a function of the main fuel map. At the desired boost and rpm point you will use this map to subtract fuel from your main fuel map. Element Tuning customers can be provided with this map.



It's important to reduce fuel in this map only when water flow is realized. So if your Hydramist turns on at 10 psi do not remove fuel until after 10 psi. This map shows 2 degrees of timing added into the idle areas. This was used just for testing to ensure the map switching operation was functional. 

 

While the Hydramist is active, ignition timing is controlled by the Spark Auxiliary Trim Map. This map is a function of the main spark map. At the desired boost and rpm point you will use this map to add ignition timing to your main spark map. Element Tuning customers can be provided with this map.



It's important to add ignition timing into this map only when water flow is realized. So if your Hydramist turns on at 10 psi do not add ignition timing until after 10 psi. This map shows 2 degrees of timing added into the idle areas. This was used just for testing to ensure the map switching operation was functional.



To activate your Hydramist system you must press (red) the "on" button. When "on" the Hydramist is active and your Auxiliary Maps are enabled. If within 2 seconds of your HSV injecting water flow is not realized then the Hydra will revert to the standard fuel and spark maps. When the Hydramist DDS3 Diplay Gauge is "off" the Hydra reverts to the standard fuel and spark maps.
