I can't really talk details just yet. I will post up the info as it comes in. Thanks guys. I'm getting the jb4 again as I want to do a comparison between the 2 first hand. No DP yet though. Just tune and exhaust. MPPK intake as well, so stock intake with a red hole..lol

[FC4]

Sure looks "sophisticated" compared to the JB4. LOL

Lots of dog & pony tap dancing but not much on actual features. Additionally, it does not work with electric waste gates like the JB4 does, so much for exceptional engineering on Dinan's part.

Any updates ?

[martinf79]

ANyone bite on this yet?

[tsims619]

I've ordered mine through my dealership and it seems that there's currently a back order on this due to not having the harness available. Will update when installed but the quoted "60hp and 75tq" sounds promising

I'm assuming you have a F30 335i? Since in your profile it says you have a 328i.

I know Dinan says its 60hp and 75tq over stock but lets be real we know the engines are underrated. So is this 60 and 75 over stock based on 300hp and 300tq or what it is really making since it would make the 60 and 75 numbers much lower.

This is why we need a dyno that Dinan should provide as part of marketing. Honestly until we can get some more clear answers from Dinan it's almost stupid buying this tune. Because if the numbers of 60hp and 75tq is just over the quoted 300/300 then this tune isn't making much more than the MPPK and Dinan is ripping everyone off big time.

I'd be willing bet a large sum of money we would know the truth based on their answer. Because for their sake those numbers better be over whatever they got after dynoing a stock car and not on top of bmws numbers.

It would be a waste of time. They'd give you some canned answer. Of course they just dynoed the car then added whatever arbitrary percentage of drivetrain loss to come up with a meaningless BHP figure. On the same premise, they can sell magic dust you sprinkle on the car which will result in a gain over the factory 300/300.

I've spoken to them about it and was less interested after the phone call. There will be no data logging or code clearing capability, no user selectable maps on the fly, and no further support for real modifications. They're developing an intake and that's about it...it won't even support a catless downpipe or anything meaningful. Their "Stage 2" will just bump things a little higher than the sandbagged "Stage 1."

I have no doubt it will be a "good" product...worry free, simple, no driveability/surging/idle issues, and nothing to constantly fuss with. Basically, an MPPK for double the price.

Not exactly, its a piggy back not a re-flash like the MPPK. Its about 4X the cost of the JB4/ISO piggy back with none of the BMS features.

Yea my profile is not updated... Traded the 28i for the 35

Thanks. It's pretty obvious we're all well aware of that.

What I mean in comparing to the MPPK is the end-user experience in terms of features, functionality, and performance...no expandability for more mods or different fuel, no logging, no code-clearing, no map switching, etc. In that regard, it's no different than the MPPK. I'm sure the difference in performance will be as equally underwhelming.

Dinan provides a parallel warranty with their products, which has to be paid for somehow; with the other providers, you pay your money and take your chances. Dinan typically makes their tuning software less aggressive to lessen the chance of tune-related issues. To some folks, the freedom from hassle by the dealer for aftermarket tunes is worth the money - especially if you wait for them to have a "sale" and get it for less than MSRP. Dinan's not all that bad when you look at Alpina, Schnitzer, or other BMW-accepted European Tuners who also provide non-flash tuning.

That said, they started out with a tune for engines not equipped with MPPK and are releasing one for those that have the MPPK installed. My guess is that their tune will produce significantly more power than the MPPK does and, as they've done in the past, there may be upgrades similar to their previous S1, S2, and S3-level tunes.

Here's an interesting thought: BMW now produces the very same N55 engine in several different power levels - 300, 320, and 333/335, depending on which line it's installed in and whether it has the MPPK. I drove a 2013 640i Gran Coupe loaner while waiting for my 2013 335i to arrive, and it was rated at 335 without any MPPK as I recall. The new M235i Racing model is supposed to have 333 hp.

Hey all - new to the forums here. Just got a new 2014 335i a week ago and I have a Dinan tune & exhaust on order which I got at a huge discount during the purchasing negotiations.

This will be the first car that I'll be tuning as both of my previous cars were leases (s5 & isf) and I purchased this one.

I did my research prior to settling on Dinan and decided to pull the trigger mainly for the warranty and peace of mind aspect of it (and the fact that I have 0 mechanical ability so this seems like a good option for me) even though it is roughly 3 times as much as other tunes.

I actually have to wait for the electronic waste gate compatible version to come out, which Dinan said is about 1-2 months away. Will post updates as I get them.

I really think you're missing the point of why some people are really angry and upset with Dinan for this product.

First off I don't think anyone is questioning why Dinan has to charge more since they do offer their matched warranty parallel to BMW's warranty. I get that and expected to pay more for Dinan if I went that route. However Dinan's strength has always been flash tunes for the price of $2k. Instead we got a piggyback tune.

Again I'm fine with the piggyback if it really is more sophisticated and can offer levels of refinement and power delivery similar to how a very good flash tune would have been.

BUT, and this is where I get really angry, we have NO data. We all know they have dynos of all the data and the before and afters. All they tell us is 364 hp and 375 tq. But how is this 64 hp and 75 tq being calculated? If they are just saying these will be the new Crank HP and TQ numbers then we know this tune doesn't offer much more than the MPPK and is a total ripoff. If they really offer 65 hp and 75 tq over what they dyno'ed a stock car at then it's somewhat worth it especially at a sale price when they sometimes discount it 25%.

I'm mad at Dinan because we know they have all the numbers and don't tell us. One person above said he even called them. What's to hide? It's an insult to all of US and very arrogant of them to think we should just fork over $2k especially when they won't release solid data for the consumers.

I really think the BMW MPPK threw a curveball at them along with the fact that the encryption was near impossible to break and now they are just doing what they can to make money off this. Until I'm proved wrong I'm sticking with this...

Personally I thought the stage 2 tune for the N54 was excellent value for money, especially at $1500. Unfortunately, my 2007 335i coupe didn't really have the stiffness or traction to take full advantage. If Dinan introduces a tune for the MPPK taking the car to N54 stage 2 levels I'll be very interested - especially as I'm confident that the 435i xDrive chassis is capable of really utilizing that kind of horsepower and torque.

Reading their website's info just now, they're quoting power increases the same way they did for their N54 and earlier N55 software. It's my understanding that they use a chassis dyno to arrive at their stated figures, and I think a 64 HP increase is a lot more than the stated 20HP for the earlier MPPK and 35 for the newer one. I also believe the MPPK is under-rated, but even so, this is still an increase in HP, plus they clearly state that updated maps will be available and can be switched via bluetooth connection. They also state that their add-on ECU can communicate with the electronically-controlled transmission and chassis components in the same way the MPPK updates those settings, so they're offering more than just an engine-power bump. If you read closely, they also have a 3-day money-back guarantee, and that would give the doubting-Thomases time to put their car on a dyno and get their own readings and decide if they want their money back.

I will be looking seriously at this even though I have the early MPPK installed. If their add-on ECU will bump power significantly beyond what the MPPK adds, can modify trans and chassis settings plus allow switching maps between normal and more aggressive parameters and enables periodic new base-software updates, it's a cut above the rest.

You are aware that Dinan markets a line of chassis-tuning parts (springs, struts, sway bars, etc.) as well as engine performance software, correct? I had Dinan S3, their exhaust and CF CAI on my 2007 E92 335i with the sport-package suspension, along with an ER Sport oil cooler and ETS 5" intercooler. I didn't experience any traction or stiffness issues - although I didn't track the car. I would have added their chassis parts if I was going to spend a lot of time on the track. For the street, I bumped the tire sizes 1 notch to 265 rear and 235 front (non-runflats) and that worked well.

Sorry I don't know if I agree. First off if Dinan is quoting numbers at the engine at 364hp and 375tq compare that to what people are getting to the wheels on stock and MPPKed cars. Then add the drivetrain loss and see where you end up. The problem I have is when you do the calculation that way I dont think the Dinan is making that much more than a MPPK car. And the Dinan tune for an MPPK car is not going to make more power I'm pretty sure they are just making it so its compatible to use.

And the 3 day return policy is a joke. And you also have to pay for the install like they state on their website at a local Dinan facility. And maybe have to pay for uninstall too?

I'm just saying if they were really confident with their product they should have tons of data to backup their claims.

Visit their website and look at the performance software upgrades for the N54 and early N55 engines - no dyno figures/charts anywhere. They're using the same method to measure HP as in the past; plenty of people, including myself, have taken their figures as accurate. If they state a 64HP increase over stock, it's flywheel HP, which is the same way hp is quoted by BMW for their MPPK for their 20/35 hp increases. Measuring apples to apples (flywheel hp to flywheel hp), Dinan's stated gains are greater than that of the MPPK. Eventually, someone on this forum will get one and do a before/after roller-dyno comparison on their car and we can see how true the claims are. Even then, figures vary from dyno to dyno, so personal experience is probably the best way to judge.

Of note, Dinan is now marketing rebuilt and larger-compressor turbos and a stage 4 software upgrade for N54 engines, which requires a larger intercooler and oil cooler, and along with their CAI and exhaust produces 444 hp, but is clearly designated for TRACK USE ONLY. This is likely an outgrowth of their racing engine business. None of this is cheap, though - same as Hartge, Active Autowerke, Schnitzer and the other premier tuners out there.
