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

[shams1924]

seems that alot of mini r56 have started ordering the aquamist. good news richard!!!
i think they may have grew in confidence.
im sure this thread will help alot of these owners. are the new hsf4 instructions updated for the r56? like where to tap into the ecu, as the hfs3, there was a wrong pin connection

Well, I have tried installation of all three restrictors and there was NO flow with ANY of them (((
And this was regardless of FAV - even with FAV detached there was 0.001% of water coming out of restrictor.

Richard, is it anyhow possible to determine why this happens? I remember than shams1924 also have had such issue and could not resolve it at all...
If still restrictors do not help - is there any was to change my big injectors (1.0 and 0.9 mm) to the smaller size (0.5 or 0.6 mm)?

Are you saying you have no gauge bar display or no water flow pass the jet?


sofric, good point and well picked out...

Shams problem was due to the controller's flow table mos-matching the actual flow (too low for the display even with the SC at fully clockwised). Since then, he has sent the controller to us and got it eflashed.

The HFS (High Flow System) is designed with two nozzles operation in mind. For low flow application as in low-boost/small engines, the flow table of the controller needs to be reflashed. Jeff at Howerton Engineering in the US and us in UK, who will gladly do as a free service if you pay the return postage. unfortunately we don't have another dealer outside this

Richard, there is no flow at all - even with FAV detached and using SYS jumper to start pump on full load.
I have just started fine-tuning of my car's ECU, so don't want to send the package back - just really very curious on why restrictors do not work at all?

If needed I can make some video of failure with restrictors...

The restrictor is just a simple tube with a fixe-sized hole drilled.

Can you see through the hole, if you can't it is blocked. Send me a picture of the install of your restrictor. I have seen one time in the past people put it in the wrong side of the inlet fitting. Here is a diagram how it should be placed:




Question: can you tell me the numbers on the small label on the left side of the circuit board. This will tell me the flow table flashed into your controller.

[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.

just a few pics i had, of the tank and custom bracket i made to hand the gauge

[Richard L]

thanks for the pictures. Do you have one taken near dust or with some background lighting.

I have just installed the HFS3 with the mini tank (right side).
When the meth kicks in (based on the gauge), there is a loud fluttering sound in the left trunk side of the car.

Anyone knows if thats normal?
