Had my Dinantronics installed last Friday but haven't yet had a chance to give it a true test except for a single quick hard run from a freeway onramp metering light. Based just off of that I felt that it definitely pulls harder and feels lighter on its feet. Drivability-wise I'd say that you wouldn't know that it was even there until you mash the pedal or drop it into Sport mode (which I consider a good thing). I fostered a secret hope that the tune would also address the throttle lag issue but alas...it's still there. Now thinking of putting in the Remus Responder in hopes of fixing that. I already had the car's software updated to SIB 24 02 12 about 2 years ago which is supposed to address that but at most it has reduced the lag.
However since having it installed there has been a pulsing in the engine RPM when idling where it would dip down momentarily--nearly to the point of stalling out--before returning to normal. This happens while parked or while stopped at a light and typically dips about half dozen times. I'm a little worried that this could actually kill the engine when I'm stopped at a light or accelerating away so I'm going back to Dinan to have them take a look just in case. Hopefully it's just a loose connection. |

Why do folks choose this brand of tuner? I am familiar with race tuners in general and I'm wondering what makes Dinantronics so appealing?
You have options for $279 up to 2k. I know you get what you pay for, I just want to know what this manufacture does different from others to warrant the cost. Not trying to be a jerk, just want to gather the facts to help me make an educated decision. |

The main difference is the warranty. If something fails and bmw won't cover the failure because of the tune Dinan will cover the repair. Dinan is also a reputable tuner and it has an established dealer network.

1.) We offer a factory matching 4yr/50k mile warranty. If something goes wrong in the new car warranty period either BMW or Dinan has you covered. End of story. No one else can claim this. 2.) 50 State emissions legal. Again no one else can claim this. 3.) Most importantly, engineering and know how that is designed to make your BMW act just like it is supposed to from the factory, just with more power and precision. Could we make more power, probably, but drivability would suffer and then it wouldn't have the hallmarks BMW is known for in their 'ultimate driving machine'. |

Any guesstimate on when the Dinan tune may include removing speed limiter?

Nope. Honestly it would be a total shot in the dark as to any guess I could provide. All I know is its a problem they are working on they are working on theories as to how they wish to accomplish the task.

Yep I have tried getting an even newer flash after I heard about it on this forum but ran into the dreaded "cannot reproduce, everything is operating within normal parameters" response. I may ask them to update one last time on during my next scheduled service citing the same throttle lag but frankly I'm getting tired of repeating myself.

Yeah, it does get old going in there and saying the same thing over and over again. And then they just tell you to drive it in sport all the time.
It is really easy to reproduce though, pull up to an intersection, slowly moving up to turn into traffic, stop and then press the gas pedal. Instead of going anywhere, the vehicle waits for a second before it responds to any input. Then you take off like an idiot because you keep pushing the pedal down further and not going anywhere until it decides to respond. Of course, then they'll say that's what it's supposed to do and to use sport mode instead. At least we know there are tunes with it fixed, it's a just getting one flashed if you need it that's the problem.

I was on the latest DME code for the X5 ZMX package, nothing the dealership could do. BMW NA told me the same thing. That's the problem with buying a single year only option, no reason to fix it going forward. It's definitely been fixed in the X3 though if the dealer will update the vehicle.
On topic, it is disappointing that Dinan isn't offering flash tunes, hopefully this piggyback is just as good but I'd much rather have a flash tune built on the latest BMW code.

How about dual quad exhausts?

I have installed burger tuning stage 1 which helped quite a bit, but it could still be better. I guess a ecu based tune might fix the issue? |

Guys, I'm scheduled for a Dinan perf upgrade next Monday through my BMW Dealer... received a pretty good discount at $1900 fully installed.
Those of you who've taken the plunge, after now experiencing the perf upgrade, do you believe it's worth the investment (at least to get me by before the X3M launches in 2017)? thanks.... |

Thanks 'speed racer', appreciate your feedback. I'm going forward with the upgrade next Monday, and agree that Dinan's proven hardware/ software and BMW's installation/ warrantee is much comfort. Looking forward to my new X3 35i M-Sport!
