The Aquamist HFS2-v3 is electrically and mechanically identical to HFS-3 except the for the failsafe components (no dash gauge and flow sensor).
Aquamist has been pioneering the IDC based water injection system since 2003 with great success. The HFS2/3-pwm system is designed to complete the Aquamist’s PWM-valve delivery system line-up, it allows precise metering of water/methanol injection for the modern high performance engine. The dash gauge, flow sensor and “Plug and Play” features are standard to minimise installation time.
The system retrieves the fuel flow (IDC) and manifold pressure signals (MPS) from the engine management system as the prime source to control the flow of water. This enables perfect balance of water to fuel flow under all engine loads. The system can also be controlled by a third-party ECU with its own custom water/methanol flow map.
A “Fast Acting Valve” (FAV) controls the delivery rate based on the PWM signal from the HFS-3 controller. A constant line pressure (160 psi) is provided by the Aquatec pumpworking in the “by-pass” mode. A PWM valve system guarantees wide dynamic range. Currently, aquamist is the only company uses a PWM-valve delivery method. Not to be confused with a progressive pump speed (PPS) system with a slow on/off valve to stop dribble.
HFS-2 is designed for non-critical application where a failsafe is not needed. A dash switch is provided instead. The user can disable the system and reduce the manifold pressure to wastegate pressure if needed.
