For those who want 3-D water injection but without the task of mapping a drive, this 2C add on is for you. The heart of the system is a newly developed controller that reads the PWM signal from the engine's fuel injector (inc. peak and hold type). It converts the signals to drive the High Speed Valve to regulate water flow and draws less than 10ma from the pulsed line enabling the water injection to follow a fixed water/fuel ratio. A 3-30 psi adjustable pressure switch (normally closed) sets the 'cut-in' point relative to the manifold pressure. Measuring no bigger than 48mm x 42mm x 21mm(H) (flanges not inc.), it has an output current drive of 1.5A. The system provides a pre-pressurised water line up to 8 bar, and the flow rate is metered by ERL's High Speed Valve (HSV). The inline valve is made from high grade stainless steel

It converts it to 0-5V analogue voltage, for data logging purposes or to find out if your stock injectors have maxed out. Two LEDs are mounted on the topside of the box, a green LED indicates successful detection of fuel injection pulses, a red LED illuminates when water is being injected (preset manifold pressure is reached). The system will detect a blocked water jet. It reads the pulsed signal from the centre pin of the Aquamist pump, and then comparing it to the water valve pulses, it flags an error signal to another 1.5A output drive. This triggers a relay or 'boost limiting solenoid valve' to bring the boost pressure to a safe level, should a blocked jet be detected.
