has anyone done the Dinan upgrade on a 750
 
I am trying to decide if i want the Dinan SW upgrade to my 2009 750LI.
I know i will like the power, but is it still a drivable car. 90% of the time i will not be using the power this beast will put out.

My car is being programmed as we speak! Stage 2. It's amazing, worth every penny

There's plenty of 5 Series owners with Dinan Stage 2 and I don't think I've read one complaint.

PREDATOR 007 07-07-2012 05:22 AM

I really want to do it, but my dealer is just getting the program and have not given me a price. Stage 1 is the program and stage 2 is program with more aggressive shifting correct? I am also curious to see how big of a difference it makes with the larger/heavier 7 series.

dunderhi 07-07-2012 08:46 AM

The 5 Series has Stages 1,2, & 3, where Stage 3 is designed for a lower back-pressure. The 7 Series only gets 1 & 2. Stage 1 shifts softer in 1st & 2nd gears, whereas Stage 2 shifts aggressively in every gear when asked. Most 5 Series owners prefer Stage 2. BTW, I have Stage 3 and it doesn't feel any different from Stage 2.

From Dinan webssite: Stage 1 & stage 2 are software upgrades.
Stage 1 Performance Engine Software/Boost Upgrade - 750
The results of Dinan's tuning are nothing short of breathtaking, with the added boost and related re-calibration producing a maximum output of 495 horsepower at 5000 rpm and 573 lb-ft torque at 3500 rpm.

Stage 2 Performance Engine Software/Boost Upgrade - 750i
After many hours of further research, tuning and testing we have improved on our hugely popular Stage 1 Performance Software. Our team was able to make Stage 2 much faster by.. improving turbo response across the power-band. This tuning is especially noticeable in the first two gears, now catapulting the car off the line. Tuned for a smooth power-band to put down predictable and even power in all gears and throttle positions. This smoothness improves the quality of the shifting and the overall drivability.

From a standing start (with the traction control fully disengaged) all it takes is the press of the throttle to the floor to get the tires spinning. The everyday practicality of a full size sedan with the fun of a sports car, this is the definition of "Performance Without Sacrifice".

With Dinan's software, your 750i will be capable of achieving its natural top speed as the governor has been removed. And as always, Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages. No one offers better performance or backs it up with such comprehensive warranty coverage.

the Dinan website also says that Stage 2 software is only good on cars manufactured after Sept 2009
where do i find the manufacture date?

Driver side door jam.

I just got my car back from the dealer. I haven't had a chance to open it up, but it definitely feels faster and lighter.

Cool, give us a review after some test drives. :)

PREDATOR 007 07-07-2012 02:48 PM

Sounds like Stage 2 is geared more like the Sport and Sport+ mode. Is it possible to have the shifting more like the Comfort setting when just doing the casual driving or is it all or nothing?

dunderhi 07-07-2012 04:01 PM

You can start with Stage 1 and if that isn't aggressive enough just pay the difference and get Stage 2. If you don't like that, they can knock it back to Stage 1. IIRC, Dinan has a pretty good refund policy if you aren't happy.

PREDATOR 007 07-10-2012 03:59 PM

I have really been considering the Dinan upgrade so I stopped by the dealer today to see if I could make a deal. Just so happened that the Dinan rep was there with his 5 series. His car was equipped with the stage 2 that provided I think 6 more hp and a few extra pounds of torque over stage 1. Now the test drive!! I started the car and immediately noticed the Dinan exhaust. The rumble was incredible. I noticed a definite boost in power. The car accelerated much faster than stock. As we were driving I was trying to figure out how the 5 series would be compared to the larger 7. Not sure how much more a 7 weighs more than a 5, but I would guess 600-700lbs. In any case the car ran great. On the highway at 70mph and stomping the accelerator the car pulled hard. Still waiting to see if the dealer will cut me any kind of break. I won't hold my breath, but I can at least dream. I will let you know what I come up with.

Individual750LI 07-10-2012 05:11 PM

I doubt they will have any discount except sometimes the Dinan will offer 10% off, usually end of the year though.

Can you let us know how this affects your mileage? Iím sure your first couple of weeks are going to suck because you are going to be racing everywhere.:D Hopefully when you return to ďnormalĒ driving your mileage will be almost the same.

nyranger74 07-11-2012 08:21 AM

The Dinan tune doesn't affect mpg. It didn't on my old X5 and it doesn't on the 7. I really haven't been in a situation where I can really open it up, but the power is certainly noticeable.

PREDATOR 007 07-11-2012 08:39 AM

That's good to know. My dealer said that it would affect the gas mileage and the Dinan website eludes to the fact it may use "slightly more gas".

MPG with Performance Software on a turbo car?:
This is the beauty of a turbo engine. When the engine is not in boost (below about 3K rpm) it is sipping gas like a small non-turbo engine would. It is only in higher boost levels that more fuel is used. It all depends on your right foot, if you drive gently the car will use the same or slightly more gas than stock and if you drive it at wide open it will use more.

I'm just curious. What is the ball park cost for an upgrade?

PREDATOR 007 07-11-2012 10:18 AM

Stage 1 will be around 3200-3300 including labor and tax. This is with no discounts.

Individual750LI 07-11-2012 11:20 AM

Hmm, dealer shouldn't charge you labor, I have read a lot of members here didn't get charged.

nyranger74 07-11-2012 01:51 PM

It says 0.5 labor hours on their site

PREDATOR 007 07-11-2012 05:06 PM

My dealer gave me a little break on the price, but their estimate included $60 for labor. Iím not going to argue it, as they are treating me fair. I have my appointment to take the car in first thing Friday morning for the stage 1. Iím gonna hit the track tomorrow so I can establish some base times to compare to after the upgrade.

Individual750LI 07-11-2012 05:28 PM

Do you mind to tell us how much discount they gave you? Maybe I can try with my dealer too. :)

To putt through a parking lot, you really need to put it in comfort. It kinda jerks too much in sport just feathering the gas.
