Aquamist HFS-4 Release

[LASRGUY]

I replaced my hfs-3 controller with the new hfs-4 today but I didn't have a chance to fiddle with the settings. I noticed the bars on the gauge seemed to bounce around quite a bit and I didn't hear the pump actually come on. I think maybe I need to tap another wire to the ECU to monitor the fuel pressure. If anyone has been through the hfs-3 to hfs-4 upgrade process on a R56, I'd be interested in hearing what you did to get the new system dialed in.
