I was surprised to read over on the F30 forum that someone who just got the Dinan Tune 1) didn't notice a difference right off the bat...but did later, after "a bit of learning curve on the computer for the tune to kick in" and 2) first gear is jerky in Sport Auto mode and "not as smooth on acceleration as I would like it to be".

I don't know much about Tunes so maybe someone can chime in but why would there be any delay in feeling a difference? Shouldn't it work right off the bat, as soon as it's installed?

Bennu, if you watch the video you'll see the part where he mentions that the current piggy back tunes out there currently do not hit all the necessary components and that if they were designed to you'd see a lot more cabling (to hit the additional sensors). It's scary how simple we seem to think this process is. Clearly in the video he explains how piggy back tricks the ecu. Now take a look at their module... it clearly has more connections. Again it seems like the smart guys have to sit here and have pointless discussions with folks that are just concentrated on bang for buck. Buy the cheap shit and good luck with your car.

Then doesn't the idea of voiding warranty for the cheaper piggy back seem less significant now? Yeah I know their answer is that they have more testing done but doesn't that just sound like a company talking points memo?

Anyone in sales knows that before you give the price of your product, especially if yours is higher than the competition, you must justify why your product is at the price it is. That is what I meant by the talking point memo comment earlier.

This discussion Dinan Tune vs Piggy back has been killed to death on the forums for years, and now they are using the very same technology that their old talking point memos were against. What's the difference? Theirs has more bla bla bla. Lol How convenient.

Marketing is a hell of a thing. I guess it's justifiable now.

I can see how it contradicts their original message but at the same time it I'm gathering that the tunes work different. I personally want to pick what's best for my car. Regardless of past marketing.

It works the same, but they say they control more sensors than the avg piggy tune. Maybe? If they want to prove their point, they should break down what theirs does vs jb4, Vishnu, Cobb, etc.

At the risk of throwing more fuel on this Dinan vs JB4 fire I have been running the JB4 Stage 1 for nearly 2000 miles on my M235i now. No problems or anything negative to say about the JB4. Nice power and super easy installation that any car novice can install. That said, I will be switching to the Dinan Stage 1 shortly for my car. I ran the Dinan Stage 2 in my N54 335i a few years back and loved the extra torque it adds. Granted I could get the same torque numbers by going with the full JB4 and have some added monitoring features, but I like a clean simple tune installation. No wire splicing or extra monitors to play with. Dinan tune was great in my last BMW and should be just as good in my current BMW. Extra bonus is my selling BMW dealer is also a Dinan dealer and will install and service all Dinan performance parts as well.

For me, it's a matter of choice as both products deliver performance. You can go with the big performance name that has a high cost, or go with a more affordable unit that has more tuning features to play with. As we have seen, if you not careful with going with the full JB4 you could cause some headaches for yourself and car. Good luck to all who choose a tune for their cars whether it be Dinan or something else.

Does one really have to go into a Dinan shop to install? It's a piggyback...

I may be joining you on that Dinan 1 boat but haven't committed 100% just yet. I usually go to BMW of Ffx which is also a Dinan dealer so I would have no problems there.

Define piggyback? Is it like the JB4, no! Is it like the BMW ECU? Why yes it is. Dinan is using the new ECU to recode all the signals he feels need to be touched without modifying the factory code any longer. Safer, easier for his engineers to duplicate as they write for basically the same ECU every time. You can't really call it "piggyback" that simply tricks signal coming out of the factory ECU (as most piggyback systems do), it re-codes many, many factory controls so everything plays nice.

As far as installation, the Dinan Dtronics Tuner goes, your VIN is coded into the the unit, and all the Dinan code is uploaded into it so many features that can be reprogrammed can validate to the factory unit using your VIN key. Again, this why piggybacks are so limited as they can't control and access all the system components. This is just a new economical way for Dinan to sell you a tune that makes it easier and safer for you and them. Although the extra hardware cost is now being passed on the buyer.

[HX_Guy]

Is install cost additional or is it built into the $1999 price?

[Roshi]

I should have been more specific, and definitely not called it a piggyback. I was thinking more along the lines of a Cobb AP I had on my 2010 135, which was an absolute beast (N54). Just plug into ODBII port and you're,off - install tunes, change maps, monitor, etc. I thought the Cobb was hands down the best tune out there for my set up.

[mjposner]

Must be dealer installed:

Installation

Plug-and-Play installation in two hours or less at any of the 180+ Dinan® Dealers. While firmware is loaded directly on the ECU the model specific software will need to be downloaded into the ECU by an authorized Dinan dealer after installation. Log on to www.dinancars.com to find your nearest dealer or contact Dinan to make an appointment.

I presume install price not included, and it is a least a 2 hour job (involves downloading from Dinan.

Thats just not true anymore... Almost all sensor data can be received from a single bus. Sometimes you need to get stuff out-of-band, but its only 1 or 2 things usually.

[Uponone76]

What's the deal with the Dinan exhaust? Judging by the price I'm guessing it's just a different muffler, similar to the M performance muffler....

If it is a turbo back exhaust that's not a bad price considering the Remus is almost $3k.

[alz0rz]

Dinan claims 6hp/7ft-lbs for the $1,800 exhaust.

[bimmer4life24]

It's official...

It's been official for almost a week now!

The discussion here has been about the cost given that the JB4 can already hit these numbers fairly easily on Map 1.

Whoops! Well it is a hefty $1,999. Does JB4 void original BMW warranty?

[vinny84]

I'm sold. The Dinan tune looks like a solid offering. Like the way it's incorporated, seems to be oem-like. Would liked to have it be a flash, but this is just as good IMO.

The question for myself is, either I spend the money going the Dinan route or wait to purchase the M2 down the road.

The JB4 would not automatically void your whole warranty, but if something breaks that is related to something affected by the JB4 (pretty much any engine/driveline part) and BMW knows about the JB4, they could deny you the warranty work by saying the JB4 caused the item to break.

With Dinan, I believe they have a warranty that's parallel to BMWs meaning if something breaks, it's Dinan that pays for it to get fixed, not BMW themselves though a lot of BMW dealership seem to be Dinan authorized dealers so you'd just take your car into those BMW dealerships like normal and drop it off at service.

Sounds good I'm not a developer or an expert so I'll take you word for it.

[ManCityFan]

one tuner is now claiming to have cracked the ECU on F8X and suggesting they can do the same on a 228i: http://f80.bimmerpost.com/forums/sho....php?t=1015151

coming from the evo world, I hate the idea of a piggyback. flash is king.
