Aquamist HFS-6 High Flow Injection System

The concept behind the HFS-6 osa (open source architecture) design is somewhat unusual in many wasy in the key-tapping Digital age. It goes one step beyond the current cell by cell on-screen programming via a lap top. the only tool needed is a small screw driver. User can define the entire flow curve by manipulating four onboard trimmer potentiometers.

Each trimmer is pre-programmed with a mathematical formula to simplify the flow mapping work.

The wiring task has been revamped to cut installation time. Three dedicated color coded, pre-terminated wiring harnesses are allocated for each area of the car, covering the engine bay, ECU and water tank/pump in the trunk.

Continuing the same tradition of constant water pressure and fluid flow is controlled by newly designed inline high speed valve. The new valve is necessary to handle the new line pressure of 160psi, risen from the previous pressure of 125psi. Dash gauge, digital flow sensor, water level sensor is supplied with the system as standard.

power suppy to the system has also been simplified, directly to batter instead of searching for a suitable switched 12V supply from the fuse box as the new system has its own internal fused and power switching relay.

The HFS-6 has managed to surpass the performance of the popular HFS-5 in every department with out costing more.

Quick summary of the functions of the HFS-6's main control panel.

Jumper links (default):

System is triggered by Fuel IDC % (second from left)

Spare jumper link is in parked position

Water injection is enabled. Unlink for "dry-run" test

Three onboard LEDs:

Green LED: Fuel idc detection. Grows brighter as IDC increases

Amber LED: The trigger point is reached, water injection commences

Red LED: The water injection has almost reached its full flow.

Potentiometers to manipulate the flow curve. (Adjustment is optional - preset at 12 o'clock):

THRES ADJ: Set triggering point to start injection. Default: 42% IDC

IDC TRIM: Add or subtract IDC% from the starting point. Default: IDC-in = IDC-out

IDC gain: Alter ramp rate of the IDC-out relative to the IDC-in Default: 1:1 ratio.

BOOST COMP: Increase the flow to offset the manifold pressure. Default: 2.5V

FLSF SENS: Failsafe sensitivity/response to over or under flow spikes. Default: 400mS

FLSF RST: Failsafe reset time after trigger. Default: 3 seconds

DIM ADJ: Gauge brightness for night driving: Default: 50%
