Not sure how good the TDI box is, and what LV (who I am insured with ) would say about it.
These box's with 3 connections are not that easy on BMW's to remove quickly/easily I'm told.
I think the Boost sensor in right down the back of the engine somewhere.
Someone on here will have fitted one no doubt.
EDIT and warranty always an issue

i dont think they are that bad on this engine i am sure the bluespark twin box literally takes 3 mins to install. that is fuel pressure rail and rpm pickup.

i am sure this dinan one is the fuel pressure pickup not boost

At first, when I heard about this $249 deal from Dinan I kicked myself for paying around one grand for a bench tune (= ECU flash) up at Jarek's at JR Auto Performance in Oakville, Ontario. And then I thought to myself...sheeit, for $249 what are they going to get, a fuel rail booster? Yep, and that's what you get. And no engine warranty with Dinan to pay for BMW's salvage work in case there's an issue. (There's a reason that Dinan won't include their usual warranty on this little piggyback--yep, you guessed it!--because it's a fuel rail booster for $249!) A fuel rail booster is what it is, and the word "Dinan" doesn't make it magic. You'd best do your homework and make a rational decision before you get yourself some cheap power for your $50K car. Chances are that you'll be fine...chance being what it is, that is.

Yes, I paid another $750 for a custom tune, and I'm glad I did. The engine performance is just what I'd hoped it would be: Greatly decreased turbo lag, way more "take" down low, even and smooth acceleration all the way to the high end, much improved acceleration at the high end, and nary a hiccough along the way at any time.

you think you are the smart one ehh...

With the dinan unit. You can easily unplug it before going in for any warranty work at the dealer. With your bench flash ecu tune, you are pretty much shit out of luck with warranty as bmw can detect that your ecu is or was flashed when they plug in their obd2 tester.

Hate to break it to you...BMW can tell when you've had a piggy back tuner as well. All they have to do is delve into the ECU.

Want to avoid losing your warranty? Don't tune. Simple as that.

yeah, that's why I decided to not tune both my cars.

SECONDED, don't tune if you want to keep the warranty.
So dealers turn a blinds eye but most do not.

Both true. You won't find that the Dinan rep will tell you any different either. He's always been up front about that point.

That said, detecting a flash tune and "delving" into the ECU isn't the same either and not all tunes are alike. Reading how many times they see the ECU being flashed, which normally is only potentially done by a dealership, or reading a code stored in the ECU that gets changed because of a flash is different than detecting a piggy back which they would have to look at the history of how the car was running and the data that was stored. The memory they have in the computer isn't infinite. You could potentially disconnect a piggy back or set it to run the car normally and drive the car for a some period of time, a week or so, and store the vehicle running under normal conditions of boost, fuel delivery, etc. Then when looking they might see some stored maxes (if they do) but any recent data would show normal operation. Anything flashed tends to change counts, although there are some out there that say they have tunes that are "undetectable"

There's also the factor of what's being done in the flash or piggyback and how extreme it's running the vehicle. If the tune or piggyback is running the car on the hairy edge to max performance this increases the odds of causing some sort of failure as opposed to something providing a relatively minor bump in pwr/tq that the vehicle can operate without usually being an issue. Not all tunes and piggybacks are the same. You can look at what other owners are running and what their experiences are to get a good idea of what seems to work without issue(s) and what doesn't. If you have any major concerns then your best bet is to not play, if for no other reason it keeps your mind at peace.

What if you would run this on top of an already tuned DDE? Would there be any gains ??

Minimal, if any, I would presume. Speculation on my part as its never been tested. The real problem lies in that the tuned DDE is probably already on the threshold of going outside of acceptable tolerances so throwing something else on top will probbaly just leads to CEL's and running issues as it will be so far outside of acceptable limits.

Dinan_Engineering just a heads up, in the product page, the photo of the dyno chart is for the wrong car (MB C300 gasser). also an M57 dyno chart would be lovely too.

Does anyone have an experience with Dinantronics sport yet ?

plenty of guys on here have them, seem favorable

[FaRKle!]

So at Bimmerfest I had my 328d wagon dyno'd with the Dinan Sport module. I did two runs in stock, sport+, and race modes. Unfortunately, the dyno didn't have the necessary equipment to measure rpm and torque for diesels, but he was able to give me max HP.

Here's the results:
-Stock: 148hp
-Sport+: 157hp
-Race: 150hp

I was surprised that race was nearly identical with stock, but that also confirms what my butt dyno had told me (I couldn't really feel any difference between the two). It also explains why when I had my car dyno'd this past January that the race and stock modes looked just about identical, and I thought I had a faulty unit (ended up exchanging that unit for the current one). I guess that unit probably wasn't faulty, and I should've tried to test sport+ mode with it.

So if you get the Dinan unit, sport+ is the strongest profile, but still only gives you maybe 10hp at the wheels.

Maybe if I end up with more time and money to burn I'll try and find another dyno to see what the torque looks like.

I'd be curious to know how much more drivetrain losses there are between xDrive and RWD too.

[Dons328d]

I'm looking for a dynamic range of control type of controller and by that I mean real low throttle position efficiency to higher torque passing style of box. Coming up on the third month of ownership of my 2014 328dx luxury experiencing the Eco Pro and Sport mode capabilities. I must say that the piggy back type of tuner boxes are interesting in their claims of attaining these extremes of performance. I can control my foot for what I want. Looking for a box to do the same.
I have 10 years experience of a chipped 2006 Jetta TDI sold at 205K miles. So I am carefully, patiently looking for an improvement of the factory performance at these extreme ends...

Any more power/tune options available for 2018 328d?

Nothing in the pipeline at present.

Thanks for kind reply. That would definitely had been nice had there been an option as I would have been interested. Will have to search around then.
Thanks

Anything for a US spec 535d that won't cost me my warranty?
