AQUAMIST 806-065C HFS4-V3.1B Water / Methanol Injection Kit w/o Tank (Blue LED)

In-keeping with the excellent integration with the Di engines, the latest HFS4-v3.1 is packed with even more capabilities.  An additional AUX input (0-5V) allows the system to alter flow based on air, exhaust temperature or air fuel ratio. If one of signals exceeds a pre-set level, fail-safe will be triggered to protect your engine. The standard turbine flow sensor based fail-safe remains. A “Fast Acting Valve” (FAV) controls the delivery rate based on a PWM signal from the  HF4 controller. The FAV enables superior linearity and atomization across the entire injection range. A constant line pressure (160 psi) is provided by an Aquatec pump working in the “by-pass” mode. This method is very similar to the conventional fuel injection systems, allowing wide dynamic range and lighten responses to engine load.

The combination of quality components, superior method of delivery and a precision Di signal decoding algorithm, the HFS4-v3 remains to be the most advanced and capable water/methanol injection system in the world to date.
