Negative Affects Of Getting A Eurocharged Tune On A 2012 C63 Performance Pack
"If a customer fits an aftermarket part to a vehicle it will not affect the vehicle manufacturers warranty providing that the part fitted does not cause any consequential damage.
The aftermarket parts fitted to a vehicle are not covered by the vehicle manufacturers warranty."
This is in Australia, the response may vary by country. Here we have quite strong consumer laws - the manufacturer essentially has to demonstrate the aftermarket part caused the damage.




I thought that the P31 had lighter crank and rods but don't recall any valve train differences. Does anyone know for sure?
But a tune is cheaper when compared to all the things you need to do to increase handling (LSD, tires, suspension, lighter hood & trunk, etc).
OE has done testing on safe rev limit increases. Stock non p31 revs to 7010. P31 I believe is 7210. For a non p31 car an increase of 7300 is acceptable. The p31 with upgraded valve train can handle 7500.
So you are saying with this tune from Eurocharged, I should have no issues in terms of vital components. I will have to confirm that there is no rev increase, personally I can do without it.

I asked my dealer the position with respect to Warranty. The answer I got is:
"If a customer fits an aftermarket part to a vehicle it will not affect the vehicle manufacturers warranty providing that the part fitted does not cause any consequential damage.

Thanks for the bit of information, I asked my salesman about it since I am on a lease and he said what they don't know won't hurt me but it would be in my best interest to return the car to stock when the lease is up if I don't plan on buying it. Other than that I have not heard of or had any issues but the cars are either just chipped or an all out track car.
The blip alone is worth the $. I am not concerned with the warranty thing either really. I'm coming from a tuned ctsv wagon and the stealership never said a word.
My p31 sedan had 715 miles on it before the tune. It's just downright nasty.
When I finally got it right there was no question it was tuned. It pulled pretty hard before but now it is like a freight train. It shifts harder breaks traction significantly more than before. The downshift blip is amazing. You could pull the stereo out of the car and I would be fine. I was driving around in 100 deg weather with the windows down looking for a fence to downshift next to.
You could probably get a real good speeding ticket in the car bone stock. This eurocharged v5 tune is bound to get me thrown in jail. The car is so much more fun.
1) Does anyone know definitively if the dealer can tell that you rolled back a tune to stock form? (assuming they look for it)
2) Generally speaking, how does a tune affect driving in manual mode? I read about it affecting the 'shift points', but arent you controlling the shift points in manual? Can't you just drive it hard in manual and achieve the same effect?

There is a ton of data that can be pulled from an OEM ECU that a lot of people are not aware of and you bet those folks in Germany can really see what is going on inside there if they really wanted to.

Driving it around stock SUCKS. Since I hadn't had the car very long pre-tune, I didn't realize what a massive difference the tune made until pulling off.

Emissions in IL, I had to do the same thing. Couldn't pass emissions for 2 sensors not ready. Flashed back, and drove for a few miles and it passed.
BUT IT WAS STUPID SLOW AFTER I REFLASHED BACK.
I couldn't stand it. I drove back from the Emissions station and flashed it back before I even went in my house. IT WAS THAT ANNOYING TO BE BACK TO STOCK. As for warranty, I had no issues. I even got my whole exhaust replaced, mufflers, midpipes etc at 9k miles. It only had a very small tiny hole where the weld was for the hanger. The replaced all under my warranty.
If you can afford the tune, be able and ready to afford any major issues that may come up
Easy.
Which ones were they?
Im trying to see which tune to get. AMS is literally down the road. I have seen their AMS tune pass emissions with no issues.
The dealership i go to works on several modded cars.
Now i dont tell them its tuned and by the way i deal with them i never mention or indicate i would.
Also i dont track it or run crap out it so hopefully i will not have issues as i have 4.5 years left or 55,000 miles left on warranty.
