Mini R56 2009 Factory JCW HFS-3 Install (Cooper s owners too)

[Richard L]

Yes, thanks to Jan and Jeff at howerton engineering who worked very hard to develop this platform with aquamist systems.

As far as the HFS-4 is concerned, the user need to add one more connection to the ECU. This connection enables the system to compensate the methanol flow more accurately with fuel delivery.

The installation instruction for the H4 is the same other than the wiring diagram, which is updated with your help some months ago. Thank you.
