Introduction:
For those who want a 3-D water injection MAP but do not want to spend the time-consuming task of mapping, this system is perfect for you.

The heart of the system is a controller that reads the PWM signal from the engine's fuel injector (including Peak and Hold type) and converts it to drive the High Speed Valve to deliver water; it draws less than 10ma from the pulsed line. This will enable the water injection to follow a fixed water/fuel ratio.

A 3-30psi Adjustable Pressure Switch (normally closed) sets the cut-in point relative to the manifold pressure. It just cannot be simpler for the user.

The system provides a pre-pressurized water line up to 8 bars and the flow rate is metered by our High Speed Valve (HSV). This inline valve is made of high grade stainless steel. As usual, except for the water tank, the system is supplied with everything needed to be fitted with ease.

The Fuel Injection Amplifier v2 (FiA2) ...
Apart from mirroring the fuel injection pulses, it also monitors the fuel's duty cycle and converts it to 0-5 Volt for the purposes of data logging, or if you just want to know if your stock injectors have maxed out. Two colored LEDs are mounted on the top side of the box. The green LED indicates successful detection of fuel injection pulses and the red LED lights up when water is being injected (preset manifold pressure is reached).

There is more...
Concealed inside this tiny exterior, it holds a very important diagnostic circuitry - it will detect a BLOCKED water jet !!!
It reads the pulsed signal from the center pin of the Aquamist pump and compares it to the water valve pulses, flags an error signal to yet another 1.5A output drive, to trigger a relay or a boost limiting solenoid valve to bring the boost pressure to a safe level should a blocked jet be detected.
