HFS-3 not spraying ::mystery solved::
Car is Audi S4 2.7BiT and I?ve just installed HFS-3 system and I?m having problems with HFS-3, its not spraying. After install the system was tested by linking up ? INJ? and ?SYS?
on the controller and it was spraying. When I start the car the red "s" and w-injection lights are on in the gauge so it should be ready to spray but under acceleration I don?t see any bars lighting up to show water been sprayed. |
Re: HFS-3 not spraying
A few questions...
1. Does the green led on the controller flicker in time with RPM? 2. Is the fuel injector standard? |

2. NO, I?m running EV14 72lbs. (so roughly double over stock). |
Re: HFS-3 not spraying
What is Is the coil resistance of the EV14, 16 ohm or 2.5 ohm. If it is a 2.5ohm injector, you need to use the green harness supplied with the system.

Did the spraying test today again but the pump didn?t power up. Fisrt time we installed the system we had wrong wiring diagram for the car but that time it sprayed but had other issues HFS-3 working correctly.
This is how I did the test: 1. I disconnected the 6mm hose from FAV 2. Took the jumper from FAV (it says "inj" in the manual but its "FAV" in the controller) 3. turned on the ignition 4. Put the jumper to the SYS Nothing happened. Does this mean an install error or could I check something else? This is what the contoller looked pefore I Took the jumper from "FAV" |
Re: HFS-3 not spraying
Can you tell me the serial number of the controller. The wire of the RJ connector seemed to be pulled out.

Re: HFS-3 not spraying
Can you pm me your phone number so that I can call you and do a more detailed diagnostic work. I will be away for a week so if I can help you today, it would be good.

Please check each plug for the corrtect wire orders. Correct the order meanwhile by cut and splice. Let me know your address and I will replace the harness accordingly. It is possible that one or two of the harness were mixed up from other systems. Email me [richard@aquamist.co.uk] and I will send them when I return to my office on the 9th. |
Re: HFS-3 not spraying
The correct wire colour order of the grey harness should be... from gauge side
-(red) 2011-May on version -red -green -orange -white -yellow -blue -black -Silver brown -(brown) 2011-May on version http://www.aquamist.co.uk/HFS3/grey harness-11.gif Dispose the incorrect harness asap |
