HFS-6 manual?

[airboy]

Hi Richard

Is there a pdf version of the manual for the HFS-6? I am trying to set up a system (installed by someone else) and I am seeing strange readings on the flow meter.

The car is a Subaru STi with:
- 850cc injectors
- black jet (1mm?).
- Subaru Spec-C water tank (and level sensor I think).
- IDC trigger is set to ~30%.

I verified that if I turn off the system, the boost control defaults to wastegate pressure.

When the system is spraying, the flow meter LED would sometimes bounce up and down. The Water Level LED would sometimes light up during a pull but it doesn't seem to affect boost. Measured AFR is stable/consistent between runs.

Thanks in advance.
