Multiplier
Hi,
I recently fitted a HFS3 system, works ok. I have large 880cc injectors but only use around 50% IDC, as I understand it I need to solder the back of the board to set the multiplier? At the moment I have the trigger point adjustment all the way anti clockwise and it triggers at about 2-3psi which for me is fine but it seems to jump to around 50% duty cycle straight away on the gauge and stay there through the RPM range I have misplaced the instructions that came with the kit, I have the 20 page one but its the smaller single page one that explained what pad to solder that I have misplaced, would anyone have an online copy of it so I can read it properly please? |
Re: Multiplier
Which H3 version do you have?
|
Re: Multiplier
V3.
Bought about 4 months ago, just recently fitted. |
Re: Multiplier
Perfect.
Yes, you have a choice of x1.5 (recommended) and x2.5). The V3 manual can be downloaded at the www.aquamist-direct.com site. (in the HFS3 link) |
Re: Multiplier
How accurate is the flow sensor? It shows 75% on the standard map2 at full flow but my jetting would seem to be closer to 1200cc going by the manufacturers ratings (these are not aquamist nozzles)
|
Re: Multiplier
The flow sensor has to be calibrated to match your jet and pressure. It is not an absolute device. Any reason for mixing the components just as the jets?
A nozzle flows differently under different pressures and temperatures. Who manufacture your nozzle and what is it rated? Repeatability is the only criterion you can rely upon. |
Re: Multiplier
Thanks, I'll calibtate it today.
I had a coolingmist system with multiple jets, I replaced the system leaving the hoses and nozzles in place. 4x 0.75GPH (90% meth HFS3 system) http://i42.photobucket.com/albums/e3...-06-27-348.jpg http://i42.photobucket.com/albums/e3...-06-27-351.jpg 1x 5GPH, 1x 12GPH (90% meth HFS3 system) http://i42.photobucket.com/albums/e3...-07-09-376.jpg Pre turbo 1X 1GPH (water only being injected by a separate 250psi coolingmist system because it was spare..) http://i42.photobucket.com/albums/e3...-07-24-414.jpg |
Re: Multiplier
I counted 9 jets? There is more than normal.

Re: Multiplier
Only 7 nozzles fitted Richard.
1 pre comp, 4 in turbo, 2 just after turbo. |
Re: Multiplier
What sort of testing have you done with all these nozzles? Before and after dyno pulls?
I'm curious if so many nozzles is helping or hurting. |
