However, the Stage 3 does continue to pull right up close to red line. 15 psi max, per a call to Dinan tech services.

If I did not have CPO on my 2011, I would have gone the Cobb route. It's all about protecting your investment. For real power out of an N55, wait for the Pure Stage 2, get a charge pipe and Cobb, and let her rip.

I read on their website that they don't cover extended/CPO warranties.

Will Dinan® parts be covered under my extended/CPO warranty through BMW?
The Dinan warranty matches the new car 4 year / 50,000 mi warranty and does not cover any extended or CPO warranties. Read the full warranty here: http://www.dinancars.com/warranty.aspx

But they were transitioning out the old sport/m-sport package and as I said it was causing issues with the computers so many builds never came with the High Speed Rev Limiter option (S841 I think) which is required for the Oil Cooler. There are crazy threads on this and shady responses by BMW.

I called BMWNA many times and it took them 3 months to come back and just say "Unfortunately your car doesn't have an oil cooler and there is no retro kit".

I am very happy my '11 Xdrive Msport does have the oil cooler. It was definitely an enthusiast that ordered the car, so maybe they ordered that separately?

The parts are there for an upgraded oil cooler, but the oil cooler is definitely not there from the factory- someone ordered it and installed it for sure, perhaps with a PPK stage 2?

Car did not have a tune on it when I got it, no aux radiator or any PPK stickers. Car used to have a JB4 on it. I do have the louvered fender liner and I am pretty sure I looked to see if there was an actual cooler back there, but I can verify tonight. Mine is an early build date and was custom ordered..

[Dark_Knight_335]

That's interesting...maybe it's when they started slapping oil coolers on the early builds due to the limp home mode issues...but no you have an N55!

Oh well...sometimes you just don't look a gift horse in the mouth

Correct. But having non Dinan performance parts bolted on may invalidate the BMW CPO, whereas Dinan parts will not.

That is a misconception that would vary by dealership. Technically they could void your CPO for dinan parts. At my dealership, aftermarket parts do not automatically void warranty. I take my car in with the downpipe, chargepipe, and intake still installed. On the other hand, some dealerships will void the warranty for ANY aftermarket parts including dinan, BMS, Cobb, etc.

I bought a non-sport 335i sedan.
I got the BMW oil and water coolers installed with the PPK stage 2.

It was a PITA getting it done. I made the dealership confirm they could install the stage 2 ppk despite my car being non-sport, and they said yes. So I dropped it off to have them do that plus the M performance suspension.

2 weeks of driving a loaner later, they call me back saying they can't install the ppk because my car isn't sport and doesn't have the right software or cooler. They ask if I still want the suspension, and I tell them no, I don't want them to do anything. Just give me the car back and I'll bring it to a Dinan dealership.
They figured out how to install it after that. Took them another 3 weeks, but they did it. They had to punch a hole in my non sport bumper louvre blank to get air to the cooler, but they did it.

Considering they were able to install it in my car, I have a hard time believing they couldn't do so for you.

False. JB is correct- Dinan parts will absolutely blow your chances of being a CPO as well. I was told that from the Dinan rep himself from prestige BMW in Ramsey NJ

What exactly does the Cobb do? When you install it, does it overwrite the OEM or Dinan software that is installed already? Or does it simply adjust the existing software with Cobb maps?

If I have Dinan installed, and removed the Cobb, will the Dinan software be gone?

The first time you install a cobb tune, it takes a back up of the current DME settings for safety reasons. If you have a Dinan tune installed, that means it will back up your Dinan settings. It then completely flashes your dme by writing over anything that's on it. It will not run alongside your Dinan tune, it's going to completely replace it. If you decide to uninstall the cobb, it will reset your dme back to its original state which in your case would be the Dinan settings.

[Mannix]

So if you install the Cobb, and run on "stock map", then it would run as if it had the original OEM software on the DME?

There is no "stock map". Stock map would be uninstalling it in which case you'd be back to the dinan tune.

I see. JB4 has a "stock" setting, right? I thought Cobb had one too.

So I guess if I want to keep the Dinan, and be able to alternate between it and some other map, then I need to get a JB4 (or some other "piggyback" tuner).

Or, reflash my computer every time with the Cobb. And that's not good since there are a limited number of flashes you can perform, correct?

Yes the jb4 has a stock bypass map which is map 0. I think the better question would be why would you want to switch back and forth? Cobb has a map that's similar to the dinan's power and that's stage 1 sport. It takes about 30-45 seconds to change the maps. And the jb4's map 1 would be comparable also. There's really no need for the Dinan tune if you have the cobb or jb4. If you mean for dealership visits then you'll want to completely remove the tune regardless if it's a cobb or jb4. And no there is no limit to how many times you can flash the car.

So strange seeing the horrid peak hp gains ...what’s deal with that ?

Was considering a dinan s2 now may be jb4 no brainer

Since this thread is very old I would not expect a response. If you have not purchased a tune yet I would say go MHD over the JB4.

[JETmn]

Yes, MHD for sure.

[JuniorB]

It's hard to accept that a factory authorized dealer would install hard/software, only to tell you that it's not under warranty anymore? I saw a turtorial about Diinan and how there cars are powered not for maximum power, but for the most power in its useable power band.
