Using 2.0T coil packs on the 1.8T

[CamrideA4]

I just ran some logs:

https://spreadsheets.google.com/spre...ptenc&hl=en_US

Feel free to tell me if they're good or not. I know I have much less timing retard than I had before despite the temps. I was asked to log these groups from the thread on VWVortex, I don't know how to interpret the O2 or Injector timing stuff.

i should add i did buy that jetta harness, and i removed the 5th connector, and pretty much followed DIY. i removed a bit more wire but the result was the same. i got the new coils installed

[terraflata]

OK, I just didn't want people to get the wrong idea that all that would need to be done is remove the 5th cylinder wire.

With how inexpensive these harnesses are I just might have to pick one of these up myself!

You can also just buy an ATW harness to switch your coils to the newer style, then buy the 2.0 coils and adapters to make it work for an AEB. I know Tomat just bought a new harness instead of hacking up his old one to switch and delete the ICM as well.

I might have a ATW harness availible in the next few weeks. Will be parting out my car soon.

Buddy of mine put these on his GT3071 GLI and didn't notice a difference he thought I was lying. I said what are your plugs gapped to? He said he's running NGK Laser's or some shit that can't be gapped. I told him to come to my house because I have a couple sets of BKR7E brand new so we can try these out, so I gapped them to .040 and he went and did a pull....... He said big difference, smile on his face and a thumbs up. He bought the Red FSI coils for reference.

My parts aren't here yet and I have to drop the block off to the machine shop but I'm about to order these with a few other things.

[BTA4Q]

ok those threads have to be super confusing. Can someone shead some light on switching from a aeb with icm over to 2.0t coils what all is needed?

Can I use the ecs tunning auto coil pack wiring replacement and delete the icm then swap over to 2.0 coils with hold downs or what? Sorry this is not really clear and I read almost all 11 pages of crap over tehre and its not really cut and dry. Thank you for the help. I really would like to delete the icm but dont know what all parstsI am going to need to make this swap happen cleanly and its not something you can really start on and not have all the proper wiring etc to complete and be able to stop halfway in between you know. TIA

Have you looked at the audigeeks/Jeff's DIY?

That's pretty much all you need.

Ensure you have suitable heatshrink (size and temp!), be prepared to mess around with grounds. There doesn't seem to be much clarity on grounds but the easiest way is to just bridge everything and ground it at one point. But looking at the ME7 diagram will help.
For example, I will be using the known ground point at the VC(pin 4 from each coil) as well as reusing the ICM ground to pin 2 from each coil. You'll see what I mean if you look at it and compare.
*my idea may not work though!

Wiring/splicing the cyl specific trigger and 12v constant should be straight forward.

[SR-71]

SEARCH!

LOL, Winston.Podi did a thread and gained 15whp/15ft-lb on a b6 gt2871 on 18psi.

I'll be either running these or Aem pencil coils

Nope, Winston has been running Okada coilpacks for a long time, way before these came out.

[BTA4Q]

gmx sorry but that again like others was in no way clear at all esp saying my idea may not work though how is that supposed to help man?

[gmx]

You probably shouldn't do this.

[walky_talky20]

^Truth. GMX's description is perfectly understandable if you have any concept of what you are doing here. There are 2 grounds for each coil.

[BTA4Q]

I know what needs done but again people say o you can use this replacement harness from ecs and then no you cant you have to mod it. Then ground these two wires through ehre but I dont know if my idea will work doing that. So For the average person who is not that expericend with it cant really have a clear understanding of what needs done. is that other write up good. yues very good but there ahve been mixed results and people saying one thing work and another doesnt and try this guess at this. not very helpful.

I just thought with the support of major companies on here there would be some cut and dry answers. I called ecs as I live not to far from them and they are very clear over the phone etc. So I would suggest for anyone else that wants to do this call them first and dont get wrapped up and confused at the different ways/ tricks people on here are TRYING.

[Dan[FN]6262]

I found that the MkVI coils with Bosch F5DP0R spark plugs work the best on my car. I've ran 34psi, straight pump no meth, and had zero misfires.

Bosch FR5DTC's worked great also. and their way cheaper than the F5DP0R plugs

[gmx]

I'll be giving FR5DTC a shot too.

Are you doing the conversion on your bro's B5, Dan?

Flat-top MK4 coilpacks are best bang-for-the-buck when it comes to making power.

I'm sorry there wasn't a step by step guide for you to follow. However, you must understand that this an electrical modification to the car that not even a dealer would do for you. The modification is not complicated, but it is detailed. Personally when I write DIY's I try to be detailed, but sometimes you can't lay it out word for word, splice for splice. There are multiple VIN splits on the B5 chassis, and multiple different donor harnesses you can use for this that require different and specific modifications. If I were to tell you for sure "the blue wire to the pink wire", and the Passat harness you got from a junkyard has a few different colors, what am I supposed to do about that? You plug-and-go and fry your ECU, then I'm obligated to feel bad about it because I told you the step-by-step.

FWIW, I have successfully replaced the coil pack harness on an ATW with this harness (which I mentioned earlier in this thread):
http://www.ecstuning.com/Flyer-Sprin...ance/ES477951/

It worked out great, however none of the colors matched up, so you just follow the factory wiring diagram and double check your work. Car runs fantastic on MKVI Cali coils. I did take lots of photos, so I'll be doing a writeup on this at some point.

[draggin]

here is a good diy for the aeb motors. http://www.passatworld.com/forums/42...elete-diy.html

[Dan[FN]6262]

yes, I'll be swapping his coil harness for a 4 pin, then I'm going to put my bolt downs with FR5DTCs in his car. figured that would be good since my bolt downs don't even have 200 miles on them and the plugs don't even have 150 miles on them haha

[flynnr]

So how do know the optimal gap?

For instance, I bought some new bkr7e's tonight, and couldn't decide what to gap them to for the best result... I have 2871r and oem coils (not 2.0) what can I log to find the optimal gap? Or what do you guys recommend I gap it at?

[STP-Teck//]

I didnt read through all the posts, so i hope i dont get flamed if its been posted befor. But we're lucky enough to have IE here locally in SLC.

start at .035.

work down by .003 if you experience soft misfires under full boost/load.

Thanks, ill try that. Sorry for going off topic a bit. I love this thread. Hopefully I have enough spare cash to swing this mod soon.

Guys,
we have been asked to build some harnesses for AJL/AEB folk. How many of you would be interested in this?

[spindoctor]

Pricing?

If price is right, I'm in, and will spread the good news to other AJL boys here.

[G-low]

interested $?

[Wizard-of-OD]

For the entire kit i want it to be below 400 for the coil packs , adapters and harnesses

[BirdTurbo]

I would!

[Dan[FN]6262]

I have a brand new set of Issam's coil pack "adapters" or "spacers" or whatever you want to call them. Still in the sealed plastic bags. If anyone wants them, PM me. They're just taking up space on my desk lol.

Im def doing this this week. Walky where did you order the red coils from?

[walky_talky20]

Genuine Audi Parts (.com) has the best price on the coils - same price for the Red ones and the Black Cali coils, it was $15.12 each. $12 to ship 8 coils to PA, which makes it still a better price than going to my dealer parts dept. Make sure to select Audi, not VW or you won't get that price.

Thanks. I orded a set along with the spacers. Got the spacers in like 3 days. Now just waiting on my coil packs!

[Wizard-of-OD]

There is more discussion in the B6 forum guys. This would be better suited to continue over there no?

[flynnr]

Guys - i have 034IIc standalone tune, and i increased my gap to like .035ish (from .028) and i noticed a nice gain. I dont have 2.0 coils, but i think my spark might be super strong with the IIc. Is this a bad idea to run this big of gap with stock AEB coils? I havent noticed any blow by or anything, and seem to have better low end response

[walky_talky20]

I thought stock AEB coils were the weakest of the bunch (and therefore the most reliable). It certainly works the coil a bit harder, but you can always upgrade later right?

[dowsett6]

does anyone know if the 2.0L coil packs fit into the AGN valve cover? as they wouldn't be able to be bolted down

[xdewaynex]

When it comes time to purchase the ATW harness for my AEB, is it better to wire it in where the ICM is located, or should I follow the harness back further and replace as much of it as possible? Looking at the schematic on the DIY for the swap is a bit confusing, so Ive got a few questions, and wiring match up to what I got on paper. If it looks wrong, hopefully someone can correct me, or verify that its right.

On the AEB schematic, it shows the wires before the ICM being crossed to the wires after the ICM to the AEB coils. On paper I took the wires before the ICM and matched them up the wires directly to the ATW harness. Here is what I have wrote down.

Gray/Yellow from AEB to Brown/Black on pin 3 #4 ATW coil
Yellow/Gray from AEB to Gray/Black on pin 3 on #3 ATW coil
Red/Gray from AEB to Gray/Brown on pin 3 #2 ATW coil
Green/White from AEB to Gray on pin 3 #1 ATW coil

Black/Blue from AEB to Red/Green on pin 1 of all 4 ATW coils

Brown and Brown/Yellow on pins 2 and 4 on all 4 ATW coils are grounds.

The big thick Brown wire from AEB that supplied ground to ICM is no longer used.

Hoping all that makes sense, and is right. Ive stared at the schematic for a while in the past and just couldnt get it, but hopefully I do now. On the grounds, is it better for them to have their own grounding points, or just one main point?

[xdewaynex]

Can anyone shed some more light on the subject, and clarify my last post? It would definitely help out those like myself who have the ICM and want to upgrade to the 2.0 coils.

[walky_talky20]

Yes, you've got the right idea. The 4 wires from the ECU need to connect directly to each of the 4 coils. No need to patch it through at the old ICM location if you can cut them before they get there. As long as you know which wire is for what cylinder, you're golden. Please note, that I did not check the wire colors in your above post. Just confirming your method.
