not with Dinan - in a case like that Dinan would step up and cover the turbo as this would be part of their consequetial damages warranty and how they work with their dealers

Yeah I've had really good experience with the Dinan warranty myself. With the BMW side, Dinan worked closely with BMW and sorted out everything internally so my car just got fixed in a timely manner and they sorted out who would pay for what behind the scenes. Either way customer pays for nothing. It's alegit company, not some small runner in their home garage.

I don't know what half of you expect to hear from Dinan... "oh we'll cover whatever you want, no matter what"... Come on.

How long ago was this? Just curious as to exactly what was replaced as in major component or small.

It was for my e92 335i that had the notorious wastegate rattle, but I had the Dinan installed for a couple years already by that time. I took it in, and BMW said "we'll get it fixed up and figure out who'll pay for what later with Dinan." 2 new turbos/wastegates and $13,000 of parts/labor later, got the car back. Still had wastegate rattle (HAHA) and that's just because BMW bought some crappy Mitsubishi turbos... another reason I moved to MB from BMW (and for those of you complaining about all these little MB problems, grass is always greener on the other side.) But I never had to get involved. All I heard was that BMW wasn't willing to warranty the repairs because I had the Dinan installed (even though it was a known issue)... but that was the last I heard of it. Must have been around 2010 this happened? Man I feel old.

And my last post is not to say that what KJ is saying is wrong... but all I'm saying is that Dinan has been reasonable in my personal experience. The above scenario is absolutely possible, especially with how hands off MB is... BMW is MUCH more open to modifications in my experience. MB won't even touch your car if you've put a bumper sticker on it. If you were to ever have a warranty issue while on the Dinan tune, I'd say it's MB's fault, not Dinan.

Guess i'll go ahead and order the tune + some wider tires in the rear haha

skim7x

Yeah, you'll be fine with Dinan. Btw, wider tires won't give you better traction :-/ what you need is the softest rubber you can find... Hear good reviews about the ps4's, that'll be what I'm getting after my stock tires wear out.

digitalnav

Going from 265 to 275 should help a little, no?

Im getting the PS4S.

dforman15

If you're still running stock tires they are CRAP. I moved up as well to a 275 and have PSS because the PS4 were not out. Even though they are not much wider the grip level is so much better! Some people even go with 285 but I'm happy with the 275's.

skim7x

Theoretically no... Friction is a product of weight and surface area. While you increase the surface area, you'll decrease the weight per square inch.

In reality maybe it'll help a fraction, but more important is the tire compound, which I think you've chosen wisely. That said, by distributing the weight, softer rubber should last longer.

Usually people feel that they get better grip with wider tires but I suspect it's because it's a better compound or because they are coming from worn out rubber to new rubber.

Enjoy!!

Should i up the front tires by 10mm as well if i do it on rear?

Let’s keep this related to the Dinan tune and not turn it into a tires thread.

RDOCA

Yes

Any distributors/ installers in Sydney, Australia?

Sanch there's a BMW workshop in Melbourne that have been doing Dinan products for the BMW crowd for years, maybe contact them or Dinan directly to see if there's any in Sydney.

Otherwise if the one in Melbourne are going to start doing Dinan products for MB's just go for a nice long drive, the Melbourne based Brabus workshop is located just around the corner from them also you could stop in both and get modded right up haha jk. the Brabus product pricing is a joke...

If Southern BMW start up doing MB products its where I'll be going for sure in the near future

Sanch

Oh nice thanks for that, I will check them out. Ideally, I'd prefer someone in Sydney, just in case there are any issues Melbourne may become an issue.

I would have to agree with the Brabus pricing, I think there are better products out there for fraction of the price. lol

Also curious about this. I contacted Renntech about this same issue, and they said that the pops/crackles are basically eliminated with their tune. The salesman told me that they "tune for performance - not sound". The reality is that the sounds of these vehicles bring a sense of excitement and theater, which is a large reason why I bought my C63S over an M3. These sounds don't require illegal or unsafe speeds on public roads. Of course we all want performance; we are all posting about a Dinan tune! But I want to keep the balance of aggressive noises and ability to roast tires.

Not to get technical, but rubber doesn't follow the typical friction physics we all learned in high school and college. It acts much more like a 'fluid' than it does a smooth solid. All other variables held constant, more rubber does equal more grip. Whether that makes a difference to performance (and especially useable and noticeable performance) is a completely different subject.

Your last comment though, that's 1000% true and I think the entire reason people believe a certain tire has so much more grip than a comparable tire they just removed.

msd3075

Sorry.

JoelSolid

I agree with this completely! If I wanted a quiet car I would have bought a boring *** Tesla.

I know vaelin said he didn't get the exhaust firmware update so I guess we will have to wait till another member with the exhaust update and the Dinan piggy back come forward with the information. Personally I have the exhaust update and I LOVE it. I'm really close to pulling the trigger the Dinan but would like more information on this topic.

I've always wondered how this works, especially since Dinan doesn't have the dealer relationship with MB like it does with BMW.

I just keep thinking in my head about all the horror stories I've heard about home warranties. Everyone is so happy when they sign up thinking everything is covered only to find out how they really function. When they try to make a claim, they find out very quickly the enormous amount of red tape they have to go through, all the approvals that have to take place, all the run around they have to deal with juggling all the personalities they have to deal with whose entire business interest directly revolves around not covering what should be covered, and then the hassle of the shoddy repairmen they are forced to deal with if they want it covered. And in the meantime your A/C is out for over a month in the middle of a heat wave.

+1. WORST case I guess it’d just mean returning the unit for a refund if you weren’t happy, but still a minor annoyance given the 2-3 hours of lost time putting it on and taking it off, plus shipping costs.

Hopefully Dinan can comment on the impact to a car with the exhaust sound software update, definitively.

To avoid spending your money on a improvement that could cause problems down the road, spend the money on improving the most important thing to make you faster all around, yourself. Take an advanced driving course and once your abilities exceed the car's, improve the car.

msd3075

The funny thing was that I was reading an article the other day about how the only way to learn how to drive fast is to drive a slow car. You can't mask your driver faults with more power or with more grip if you're driving a slow car. You're forced to focus on getting all the details correct and learn how to carry momentum through corners instead of just powering out of them.

That being said, we're talking about power and acceleration here in this topic. A better driver can't somehow make an paddle-shift automatic, launch-control equipped car accelerate any quicker compared to what these types of tunes can do.

RENNtechHQ

Hey,
we want to clarify this statement here. Our tune does not eliminate the pops and crackles that come from the factory setup/exhaust.
Our tunes are optimized for performance, but we do not modify the settings that create the mentioned exhaust sounds.
Besides that, on of our goals is to make the cars sound more aggressive with our Downpipes and Mufflers. A large amount of our exhaust R&D time is spend on perfecting the sound of the exhaust upgrades.

Please DM us about the conversation so we can clarify the issue and answer any further questions you may have.
