Eurocharged Black Friday Sale
Eurocharged has a Black Friday Sale. It is on till Wed this week. I ordered the ECU/TCU package for my '05 V-12 S600. Regular price 1499, sale price 750.To me, at this price, it was a "I HAVE to get this" decision. I'll post results in a week or two. ECU comes with a thumb drive, the TCU requires removal and send in, one day turn around, 2-3 days down with shipping. Not wanting to have the "lack of maturity" talk again, told wife charges were for engine mounts and coil pack.

I have had my tune form EC now for about 4 years with the same coil packs my friend.
Don't listen to the hype.
PS: Enjoy the tune, I know I do

His quote was 1 in 5 coils die after a tune
(See posts 1 and 2)

In the second post the guys coils died a few days after the tune and he wouldn't have bought a tune if he knew they put more stress on the coils
You are simply lucky yours didn't fry after the tune mramg. You are the 4 out of 5 that make it ok

As one should know, ANY time you make more horsepower you have raised the combustion temperature. On the S600 this is done with more boost.
More boost does make for the spark plug to have a harder time to make a spark, as most boost junkies will shorten up the gap and run one less heat range.
Although this strain on the plug is real, there is NOTHING that the coil can do to change anything. It sees the same voltage, resistance, and amperage as long as the stock plug/gap are in place.
By the way, most boost junkies shorten the gap as it is possible that the higher boost can blow the spark out, NOT that it will eat the coil.
AS with ANYTHING, when you turn up the power, things can break. AKA physics get involved here. As far as the coil packs becoming a weak link, that would be very hard to prove indeed. My only real world guess here is that with close proximity to the head, they could see higher working temperatures. Electronics do not like heat.
Good luck OP with whatever you do, but you will love the car even more once you turn up the wick.

That's right , they never advise customers before a tune , only when they fail afterwards they give them the story that 1 out of 5 coils fail. That's the key problem I keep trying to highlight in these forums , that this risk is being hidden -and there's always people like you shouting " BS" trying to keep this information hidden .
Look, if a buyer is fully informed In Advance -and ok with the risk of premature coil failure , or have a warranty , go bananas.
But there are plenty of people not informed in advance , just like you and those others weren't informed in advance - or aware that bumping up the power can fry coils , and we don't need people like you screaming "go for it " while trying to hide the reported failures

I don't always share tusabes' negativity about V12TT reliability etc, but I think he's on target here. There's no guarantee that it will fail - but there's a significantly increased probability. Yes, there's always an exception that proves the rule, but there does seem to be a lot of anecdotal evidence about this.
Speaking from personal experience, my S600 bust a coil pack after being Eurocharge tuned, and it took me long time to get over all the misfire and CEL problems.
Part of the problem is the spark plugs. I don't think anyone uses the wrong plugs, but they have to be in good condition and the gaps have to be right. That's not something I've had to attend to for many years, but I had to get them spot on with this car.
If you're going to tune a V12TT, I'd say fit new NGK IFR6QG or Bosch FR7-KPP33U at the same time, and set the gaps to 0.7mm.
(I also made myself a new pair of coil pack heat shields to replace the ridiculous Mercedes ones. They reduced the peak working temp of the coil pack case by several deg. C. I can't say for sure whether that protects them, but its got to help.)
