Teaser 2.0T Coil packs...

**infinkc** · 10-08-2011 09:18 AM

Upated Post with all you need to DIY

Vendors say coming soon, i say now :) I have been working with an az vendor making sure that this is a worthwhile upgrade and is a user friendly mod so i will not be posting all the details yet.But will give you my impressions.

Best part so far is that you do not have to unbolt the coils now to get to the plugs or dont even have to loosen the inlets! Just pop the plug out and you can get to the plug also without removing the adapter.

There is a lot of wiggle room with the adapters im testing with, so i dont see any reason the coils will crack.

**Link to xmoox's writeup where he soldered in everything: http://www.audizine.com/forum/showth...-Solder-method

Now back to finish the wiring so i can test these things out.

Updated schematic :
You can use the existing ground for both ground pins if you like. (No need for separate grounds like the original(rev1,2) schematic, it is fine if PIN2 and 4 are connected together on the new coils.)

Rev 3 schematic:

To break it down easier:
!! NOTE:Both Banks of ICMs have the same color wires, do one at a time so you dont mix them up or your car will not start!
Bank 1 (Cylinder 1,2,3 ICMs)

4 Wire plug - Grey/Yellow (Pin 1) goes to 3 Wire plug Brown/Grey (Pin 3)
4 Wire plug - Pin 2 Brown Unused
4 Wire plug - Green/Grey (Pin 3) goes to 3 Wire plug Brown/Green (Pin 2)
4 Wire plug - White/Green (Pin 4) goes to 3 Wire plug Brown/Blue (Pin 1)

Bank 2 (Cylinder 4,5,6 ICMs)

4 Wire plug - Grey/Brown (Pin 1) goes to 3 Wire plug Brown/Grey (Pin 3)
4 Wire plug - Pin 2 Brown Unused
4 Wire plug - Green/Brown (Pin 3) goes to 3 Wire plug Brown/Green (Pin 2)
4 Wire plug - White/Brown (Pin 4) goes to 3 Wire plug Brown/Blue (Pin 1)

Coils:
New 4 wire plug (Pin1) - Red/Green on s4 harness
New 4 wire plug (Pin2) - Brown/Yellow Ground on s4 harness
New 4 wire plug (Pin3) - brown w/(blue, green, grey,) stripe on s4 harness
New 4 wire plug (Pin4) - Brown Ground on s4 harness

Rev 2 schematic if you want to use separate grounds:

Here is the parts list that i used.

06E905115E 2.07T coilpacks x6

034 Custom coilpack adapters x6 http://www.034motorsport.com/ignitio...v-p-22336.html

For the Coilpack 4pin connectors you have a few options:
1J0971658L is a complete harness repair for the 1.8t, it has 4 connectors on it so you need x2
also 1J0971658M is the same harness wired a tad different (same or cheaper, price but the other may be out of stock)
http://www.ecstuning.com/Volkswagen-...arness/ES7679/
http://www.ecstuning.com/ES2089862/

Buying the harness above is way cheaper than ordering the pins seperate and the 4 pin connectors. (edit, it is now cheaper to buy the connectors)

Cheapest place so far for 6 connectors ~$53
http://www.onlinewholesaleparts.com/vwicc-004.html
or amazon http://www.amazon.com/2011340-Igniti...ords=1J0998724

4B0906102 is the part number for the boots if you do not want to use your old ones. x6

4B0973724 is the part number for the 4 pin connector housing. x6

00979133A is the pins for the connector with a short pigtail of wire, comes with 2 so you need x12

For the ICM delete harness, why no one could find the male connectors, is cause they are a Volvo part :) Yes it took me awile to find them.
**UPDATE, if you plan on never going back, i suggust just cut and splicing the wires together for a much cleaner install.

978161 is the 4 pin connector x2
978157 is the 3 pin connector x2
978298 are the pins x12
970773 are the insulators if you want to use them x12

*** New information has come out, that you can use adapter plates off a Touareg for the coils instead of the billet adapters.
part 077 905 390 You need Qty 6 and run about ~$5ea

**NOTORIOUS VR** · 10-08-2011 09:21 AM

Very nice... do you know an approx ETA for the adaptors?

**Timtheguru** · 10-08-2011 10:09 AM

Can't wait!

**DiscoPotato** · 10-08-2011 10:13 AM

Looks good.

**crazyfasts4** · 10-08-2011 10:26 AM

This is going to be great if they will work. It wont put so much of a dent in my bank account when i need to do coil packs.

**The_Auto_Tech** · 10-08-2011 02:20 PM

All I really need is a wiring harness. I've got the connectors and coil packs sitting at work that I got for free. :)

**infinkc** · 10-08-2011 09:37 PM

Didnt want to leave you all hanging. A few more pics to show you, i will be doing a full thread on the whole setup.

As for initial impressions, WOW! i didnt think i would notice anything, but there was a big difference in response on the car. Car fired right up without any codes.

Hopefully a harness will be out soon. I do have a extra set of wiring that i can sell to another that wants to DIY if they dont want to wait for a vendor harness, will put in the classifieds shortly.

So here ya go no more ICMs!, i tucked the wires in the back. You can see the plug-in harnesses i used to bypass the connections. If someone really wanted you can just cut the connectors off and splice, but the plug n play makes it so much easier.

I went the clean route and cut off the old connectors and put new connectors in place. I would not recomend this unless you are very good at soldering/crimping these type of connectors. You can also see the extra wire needed that i ran coming out of the harness. I dont see myself ever going back to the old coils, so i didnt care that i cut off the old connectors.

**Papa_Dios** · 10-08-2011 10:31 PM

Very nice subscribed.

**Papa_Dios** · 10-08-2011 10:48 PM

To the OP I bought this harness from ECS to fix the broken connectors on my 1.8T. You think I would be able to use it (of course would need two more) for this conversion?

I actually bought this same harness x2 cause it will get you 8 connectors and wire, you only need 6 of them, so there will be 2 extra. I didnt land up using that harness since i was testing the ease of using just raw parts. I highly suggest if you are going to DIY, use that harness you posted x2 to get the connectors and wires. The cost of two of those harnesses is way cheaper than sourcing the individual pieces just to put the connectors together.

The easiest way to use that harness is to simply cut the connectors off with about 4 inches of wire to work with, then splce into the stock harness either using good butt connectors or solder with heat shrink.

The problem with the ECS unit is that it is still using the OEM wiring which cracks over time.A Good source for the connectors though.

**Audi_S4** · 10-09-2011 10:13 AM

So basicly this eliminates the ICM's ? Gives better response and ignition and less failure rate ?

**NOTORIOUS VR** · 10-09-2011 10:42 AM

I would say the failure rate of our stock ignition system (ICM's and CP's) isn't all that bad to begin with... but yes you get to eliminate the two external ICM's (but therefore the drivers/ICM is built into each and every coil itself) and you get a CP that supposedly gives you more spark energy. Not to mention the active coils are much cheaper then our stock coils.

**DonutHands** · 10-09-2011 10:52 AM

If a single coil ever goes out on me i am surely going to do this upgrade. How long till we get a wiring writeup? ETA on adapter plates?

**8520** · 10-09-2011 11:27 AM

What are we looking at for estimated cost of this conversion?

I have original coils @ 160.000km and when I ordered some parts from JHM some ime ago I ordered me 6 new Coilpacks just to have em at home if something fails. Would it be wise selling these for 300$ and buy the conversion kit ?

I have all the pictures and information to do the DIY, but not the time to upload it all. I drew out the schematics over a year ago(yea i actually posted it here, suprised no one else took off with the design), and finally decided it was long enough to get this going. My original intent was just to use the newer hitatchi bolt down coils to delete the ICMs, then i came across the 2.0 coils which i then decided to go that route to have a double benefit.

As for the adapters, they have been available for quite awhile now, you just need to search and ask for the correct quantities with the correct coil design

And if anyone is wondering, the plastic engine covers on the valve covers still fit on, they actually hold the coils down. I decided to remove mine for now since I like how the red coils appear.(you can see them, sorry my lighting sux)

I highly suggest waiting for a completed harness for this conversion, but i do support DIY 100%. Will try and get it up soon, i still want to make sure that the car doesnt run into any unforseen issues, i only have about 5 miles on it so far after the conversion.

**S4 00 2.7** · 10-09-2011 12:01 PM

Could improved response/ignition possibly unlock an extra 1 or 2 mpg?

**S-Power** · 10-09-2011 12:21 PM

Interesting...

**DonutHands** · 10-10-2011 08:36 AM

thanks for the info. glad to hear you will be providing a DIY write up.

Thanks for posting the link Kris, but that is actually a different product. The adapter you posted is for using plug wires when upgrading to our 034EFI High Output coils, which are still the most powerful coil option on the market for the 2.7T.

Our 2.0T coil adapters are $16 each and can reuse your existing hardware. We have the 2.0T FSI coils in red and black for $24 each, a significant savings over the 3 wire bolt down coils.

The adapters specifically for the 2.0T FSI coils are not currently on the website, but are available. Please PM me for more information, but we will be offering a couple pre-made options for folks who don't want to do this modification themselves.

Good info, Max.

**AMC** · 10-10-2011 01:13 PM

cant u just use 2.8 valve covers? as they use push coils?

**99blueb5** · 10-10-2011 03:13 PM

that is a good question, since they had plug wires they look the same size though, also the later gen 2.7t's that had push down coil those should be the same time for the 2.0t coils right?

**infinkc** · 10-10-2011 04:40 PM

Will find out the end of the week, filled up this morning.

One reason the adapters were made was because the 2.0 coils are taller than the standard 4.2 and 1.8 coils. So it may work but you still need an adapter. The early year ones won't work unless you cut the rubber on the coils.

**Audi_S4** · 10-11-2011 09:43 AM

So 2 x this
http://www.ecstuning.com/Search/ES76...18tcoilharness

6 coilpacks and 6 x 16$ adapters are all we need?

and the ICM connectors, unless you cut and splice the connection there.

So if you are really good with splicing and have the time you can get this done pretty cheaply.

**jibberjive** · 10-11-2011 09:52 AM

4 wires per coilpack, and 6 coilpacks = 24 splice connections?

**BeachCafeAudi** · 10-11-2011 10:06 AM

**infinkc** · 10-11-2011 10:09 AM

wow you found my old thread :) ^^ will give you a A+ for searching. Beware that that grounds on my original diagram were all tied together, i have now changed it to have the seperate grounds. As it will "work" tied together, it is not how the coils were designed.

and yes 6x4= 24 splices

**NOTORIOUS VR** · 10-11-2011 10:10 AM

Realistically... it's not that much...

you need to connect the wires from where the ICM's used to be... and although I'd have to check the pinouts for the 4 wire coils...

I'm almost sure it's just an extra ICM switching ground wire that you're adding to the harness/CP plugs (comes from ICM harness)

Since you will already have 12V+, GND, and ECU IGN signal from the 3 wire plug.

I'm assuming you're talking about using the sensor GND instead of chassis GND?

**BeachCafeAudi** · 10-11-2011 10:15 AM

its funny you say that because in your previous post, the only thing that confused me was whether to do original grounds or a common ground. you expressed some uncertainty on the issue, and of course i had uncertainty about it as well after reading your post...

glad to see you resolved that in practice and again, fantastic work my man!

**csosnowski** · 10-11-2011 10:16 AM

So that I am clear on the cp side of the wiring:

Pins 1,2,3 are already in the stock harness, pin 4 is new. Pins 2 and 4 get bridged and run to gnd with 18ga wire (or bigger).

Pin 1 is 12v
Pin 3 is trigger

So if someone didnt want to split their existing runs to the plugs, all that would need to be done is add the extra wire for pin 4 and source the connectors and pins. Or, use the 034 or ecs coil pack harness and splice in.

Plus the ICM jumpers, of course.

Does this sound about right inf?

EDIT: just saw your post about individual grounds.
