Title: DEKA 875cc FI114700 Post by: armageddon on January 19, 2016, 03:59:20 PM A friend of mine will be using this injectors.
They will be used on a RS4 B5 at stock fpr(4bar) I was able to find on the web the injectors worksheets, but they are missing the voltage offset multiplier. Is there a way to "find" the multiplier from this data or it will need to be "trial and error" using 3bar offset as a starting point? actual flow from supplier flow slip is 882cc at 3bar so KRKTE will be: 480/1018*0.06749= 0.031822 Title: Re: DEKA 875cc FI114700 Post by: armageddon on February 06, 2016, 07:30:35 AM Ok, I ended up using voltage offset values from worksheet and only had to change KRKTE
KRKTE: 0.029970 TVUB: 8v 10v 12v 14v 16v 1.998 1.368 1.029 0.787 0.645 With this LTFT are: idle b1 part b1 idle b2 part b2 0.0 1.8 0.9 2.2 Hope this would help someone intending to use this injectors Title: Re: DEKA 875cc FI114700 Post by: nyet on February 06, 2016, 11:11:58 AM Odd choice, the spray pattern really isn't appropriate for the b5 head...
Title: Re: DEKA 875cc FI114700 Post by: armageddon on February 06, 2016, 11:18:13 AM My friend wanted a plug and play solution, EV14 would be better but he didn't want to use spacers/connectors adapters.

Funny thing is both Deka 630 and 875 is like only injectors the UK b5 comunity runs. How can they be so wrong? Title: Re: DEKA 875cc FI114700 Post by: mcgas001 on February 07, 2016, 11:48:00 AM I really don't like 875cc injectors...
630cc Vs 875cc Title: Re: DEKA 875cc FI114700 Post by: vwaudiguy on February 07, 2016, 09:08:30 PM I wonder if it would look the same with a pulsewideth and a frequency? I have a matco tool that can simulate both. I'll try and setup up a jig this week.

I'll try and setup up a jig this week. Look at the datasheet. 20 degree single, on axis cone. Title: Re: DEKA 875cc FI114700 Post by: vwaudiguy on February 07, 2016, 09:40:22 PM Look at the datasheet. 20 degree single, on axis cone. Thanks Nyet. Still curious if it would look different being pulsed vs. static which I assume that it. Title: Re: DEKA 875cc FI114700 Post by: Lost on February 07, 2016, 11:27:14 PM That doesnt look good at all.
Straight down in the wall between valves. My research has shown - tha best "big" injectors for RS IM are Bosch 980 long nose 040 Title: Re: DEKA 875cc FI114700 Post by: nyet on February 07, 2016, 11:31:59 PM Research?
The 040's are also single cone. http://s4wiki.com/wiki/Fuel_injectors Please don't post stuff like that w/o substantiation. This is why there are so many terrible ideas floating around in the first place. Title: Re: DEKA 875cc FI114700 Post by: mcgas001 on February 07, 2016, 11:50:20 PM Here's the video's I found online where them pictures come from.
630cc https://www.youtube.com/watch?v=1BK2TDHzC18 875cc https://www.youtube.com/watch?v=rhB_f36a3nw The 875's seem to black smoke on boost, and give off horrid part throttle fueling. Anything bigger then 630cc I say Injector Dynamics now.

Eeek. Thanks for posting those vids. Title: Re: DEKA 875cc FI114700 Post by: armageddon on February 08, 2016, 02:14:14 AM On paper, FI114700 spray is the same as FI114961. Those on videao are the previouse version FI110324.

This is why there are so many terrible ideas floating around in the first place. I stated RS IM not S4 IM. There is a difference. It is singel cone but with 7 hole orrifice in wide angle at 30 Deg. This is the closest " Big enough injector" you will come At right angle again Nyet " RS4 B5" intake manifold. Owning it myself after been through couple diff injectors - i would call it Research, far more Research than sitting behind a computer talking abot stuff you never had or even never seen. So why dont you knock yourself and give me another carisma -. You stand for all of them anyway. I am starting to belive this is something personal. You are always on my case with some BS |
