The coil packs (or should I say pencil coils as they are not really a 'coil pack') are basically electronic inverters - the ECU just sends a digital pulse signal to them and then that is stepped up to a very high voltage.

The R8 coils are supposed to create a higher output voltage (discharge voltage) compared to the standard pencil coils - this should produce a stronger spark.

I say 'supposed' as all we have to go on is some apparent tests that hstuning done where they said they produced a visibly stronger spark when they tested them. The only reason I question their tests - as they also try to compare 'coil packs' (standard, r8 and okadas) by measuring their output resistance - this measurement is meaningless for this type of coil, it doesn't compare to the coil packs of old secondary coil resistance - simply because their is no direct secondary output coil that you can measure on a pencil coil as they are electronic switching inverters, they have output transistors and measure many megaohms of resistance - a value that is completely meaningless.

Still they are probably better than stock and many a GTI owner has said it has fixed misfiring issues and are more reliable. Plus they look pretty

This thread keeps getting better and better. Do you have a part number for the adaptor?

The adapter is custom made by TMG performance of Greece...

They do 2 versions of the adapter - the bit cheaper thinner one that leaves a gap between the adapter and the head, and the full one as pictured above.

Just the adapter:

Thanks. I've been hearing about TMG with respect to updated dq200 dsg clutches. I'm surprised it took this long for a company to release stronger ones.

Yeah I have been looking at their upgraded clutch pack - it's about time someone did it. I remember reading a couple of years ago about a company that was developing one and showed a picture of red clutch plate - it happens to have been TMG.

Looks like they took some time experimenting with different clutch materials / layout. This new one is Kevlar and supposed to be more resistant to wear / overheating.

That's the problem with the stock clutch - it can overheat in stop start traffic, which leads to glazing the surface. Once that happens its ruined and will start to slip in 2nd gear once it gets a bit hot.

In stop start traffic I go easy on the clutch, trying not let the car ride it so much.

90% of the time I drive in manual mode. I've found that it is less prone to shuddering in that mode.

My issue with the shuddering felt more like improper shift points in D mode for 2nd gear.

I've got this engine in my MK6 Golf Cabriolet (in Australia it's the only option) and have a very similar setup to you (except I'm rocking the 6 speed manual with Dieselgeek short shifter).

Being a late 2011 (MY12) build I got the later fuel pump and injectors from factory, I've updated to the APR Stage 1 in early 2012 (is there an upgraded stage 1 tune since then?) and have recently installed the GFB DV+

I've updated the code to allow a two stage ESP/ESC button found in R spec models so you can turn that off completely should you feel the need.
http://www.vwwatercooled.com.au/foru...you-81247.html

I'm running the Forge CAI and with the stage 1 it's quite loud thanks to a virtual straight pipe.

Current setup:

Note it was just as loud before the DV+, here is a vid from a few years back.

There is a Polar FIS Advanced in a drawer here somewhere too I keep meaning to put back in and after all your talk of misfires after the DV+ I'm more encouraged as it beats dragging out the Rosstech cable and laptop. I'll have to scan it all again and see, but at last check there were no faults being logged, but it's been 3 months with the DV+ now and I don't recall when I last scanned it.

Being a little warm here during summer I keep looking at an intercooler upgrade although haven't got there yet... those injectors look very tasty too, something I'd looked at in the past but they didn't fit... the adaptor plate is news to me and very attractive if it all provides a better burn.

In general performance parts for the twincharged motor in the Golf have been pretty thin since all the R&D goes into the GTI and R spec models.

Time for an update..

My problem with misfires above were down to the APR map having issues with this engine...anyway that map has gone and i have much bigger goals now.

I've been wanting to replace the camshaft adjuster, as it's an earlier revision which sticks occasionally on startup - making a loud unpleasant noise. Also my supercharger clutch / waterpump is the earlier revision which occasionally squeaks (slips), especially in hot weather.

To replace the camshaft adjuster i would need to take the timing side of the engine to bits - a big job, and i might as well put a new chain and tensioner in whilst there as there probably is some chain stretch by now (55k miles).....I also want to clean the intake valves, which as previously mentioned is a difficult job on this engine with the intake on the back side and the channels being very deep....

So if i have got to take the timing side off and all that entails, i might as well take the head off and really clean the intake and valves, even do a port and polish job - and well whilst that's off, this engine is screaming out for something special:



Yep - that's a full set of wossner forged pistons - once they are in, with a full intake clean, port and polish job, new waterpump/supercharger clutch, camshaft adjuster, timing chain & tensioner + guide rails etc....it will have a custom map for some big horsepower

Yeah, the stock rods are pretty strong....which is more than can be said for the stock pistons!

I will balance the pistons with the rods though, grinding some material off the rods if necessary.
