Re: HFS3 initial setup query post install
So back home...It's been a loooong day. A 1hr job turned into an all day. Was meant to just install new pre throttle body pipe and then start setting up water install.
8am..Drive to mates house. 9am have everything stripped . 10am...many swear words and new pipe installed.Test water system before on throttle pipe using jumpers as decribed to prime pump but not disconnecting the 6mm hose before the ......thingie goes tpo the small cable No joy... Pump doesn't seem to do anything. Light does green on dash but does not blink. Then jumpers back to stock.Tried full anti clock on threshold and full clock on gain setting still nothing even if car if blipped light does not flicker gauge or board . Got tired so plugged it all together filled up with straight water. Try start car again and find battery so flat car doesn't even start to swing :roll: 11am move pipe to stop hitting cooling fans ....nothing heavey duty cable ties can't do 1am ... Battery finished charging and went for a test drive with pump off. No problems, pipes not working loose no annomolies so getting happier 2pm. Went logging. pump off. Ambient was 27c intake temp 39c . 12c above ambient. Not too bad without meth. Max timing pull -7.5c. Turned on pump stock 12oclock both threshold and gain. 2 runs and light on dash does not blink. Couple more runs and finally once threshhold at full anti clock and gain on full clock only rougly at 17-18psi does dash light kick in and strat flashing green ...yay After many runs doesn't use much water but it is going down though. Logs on final run .Ambient still 27c. Intake 31c so 4 degrees above ambient. Getting there :roll: Timing still pulling -3 at max so better but obviously not great. Unfortunately I am away tomorrow but will try prime the pump again next weekend but doubt it will make a diffeance think it does have water and is primed. Just doesn't seem to be adjusting the way I expected. My mate with same K04 setup and this kit also same installer has his setup on 11am threshold and 2pm for gain. I don't think this is a Aquamist problem but more likley something not correct on the original install that was done even though the installer has done many W/I installs and one hfs3 already. :cry: Just wish I could get it to work correctly...Just need time I guess.:cry: |

Re: HFS3 initial setup query post install
A digital multimeter is perfect.
Here is a diagram for configuring the HFS-3 for various FI/DI engine. YOu can should be configured to B-4 and D-4. Please check the under side of the circuit board that has already been configured.

Re: HFS3 initial setup query post install
Going through to Preggie and Praga's work shop tommow @ FRC Racing. Really hoping they find with the autoelectrician something small or an installation issue.
Hopefully will get sorted and I can let you know what it was. Printer that pic above and too it down to the car and it looked like the board was set up in the same was as it should be. Will keep you posted. |

Re: HFS3 initial setup query post install
Thank you very much for the update.
It is difficult for me to help without the car in fornt of me. I would nbe grateful If you can ask Prega to take some picture of the with the wires spliced, I can them make a proper diagram to for the future. Things are looking up. Richard

Re: HFS3 initial setup query post install
Only saw your response just now. Car is going in again next week for the proper gauge to be installed.....The big one with flow meter. Will get them to take the pics then.
In the mean time. Car is running. Had both settings thresh and gain set at the 12 o'clock position. Car idled fine. dash gauge doesn't flash yet .... good. Currently running 100% water. Noticed thateven when just cruising at 120km/h or if slowing down and using the gears the water injection is constantly on and flashing(injecting) Then on the first pull the car has big skips and misses and feels like nothing wants to happen at all like it's flooding something but then once it clears in a sec or 2 it pulls like a train again. Did try adjusting the threshold and the gain but just seems to be kicking in under no load which is odd. If I have the light on the dash not flashing and is just solid green then it accelerates fine with no issues and the flashing kicks in and car pulls cleanly with no misses. Will start doing 50/50 meth water on the weekend but was puzzeled by this current new issue. Any thoughts ? What am I doing wrong ? By the way this is the 3rd waterinjection system I have owned and all have been Aqumist and never had these problems before.. Just trying to say I am used to setting these up but this one is testing me a bit |

Re: HFS3 initial setup query post install
Do you have a digital voltmeter?
The basic wiring for the IDC signal appeared to be working as design. As direct injection systems have many variations, we now need to find tune the incoming signal. At present, it appears the IDC signal is a bit on the high side. There are 30 test pins on the HFS-3. Pin16 confirm what the HFS-3 is seeing. 0-5V = 0-100% DC. If you can tell me what voltage at pin16 we are reading in the following conditions: Idle ........ ? volt cruising ....... ? volt WOT ....... ? volt Alternatively, you can put the jumper link to "FDC "and read the Fuel duty cycle % from the gauge.

Re: HFS3 initial setup query post install
Got given a Voltmetre toay :twisted:
Will try work out how to use it correctly and go find this "pin 16" Will let you know. Probably will only happen around the weekend. Will let you know . Thanks again for the help |

I have just been in touch with Morne, working on the 2008 BWA and start to make way to understand the Bosch DI system.

Will hold off sending in my car to get the gauge installed until this has been resolved. Sounds like by the end of the comming week we should be in business. I think my car is trying to keep me at home trying to watch the world cup. This morning driving with water injection off. Car had just warmed up. Had an Aston V8 next to me and a Range Rover Supercharged pushing me to go from behind. It was roughly 12c so nice and cool. Went to manual mode pulled off went to 2nd and then planted it for the first time today midway through 2nd.....and I get quite a bit of wheel spin and a nice sensation of been pushed in the seat as she scrabbles for traction....3rd and start pulling the competition as they now know I am serious.....And then ......pppppsssshhhhhhhh. Stupid new throttle pipe blows off .....grrrrrrrr. Well the soccer was pretty good Last edited by playback; 03-07-2010 at 05:58 PM. |
