They used to dinan tuning other model BMWs with a different type of Cabel. As I mentioned, I'm the first 750 owner requested this tuning. For all the trouble I went though, it's better worht it.
I'd be pissed if I were you. Ask for 10% off the tune because my dealer offered 10% off if we went in before the end of the month.

It should be 20% off dude. My dealer had agreed to give me 20% off before this incident. and they agree only charge me 0.5 hours of labor which is listed on Dinan Website. I will update you guys for the final charge.

I just spoke with a Dinan rep and he told me it is 20% off till the end of the year and it brings it down to $2399 + tax.

huanjf, tell your rep that you spoke with Dinan and the 20% off is through Dinan and you should receive an additional discount for your troubles!

I also verified the warranty issue and it is as huanjf confirmed, they will honor the extended warranty if it was purchased when the car was new. Even though I only have 20k left in my warranty, I think I will have to jump the gun and get this. For the price, you can't beat it!!!

Thank you for the advise, I will bargin another 10% off on top of original 20% off when dealer calls me. Hopefuly they will give me that, but I really doubted. I will keep you guys updated. Right now I am waiting for my dealer to call me as they need to get everything set-up on their end first

I also confirmed with my dealer that there is no labor charge. He said that is just how long it takes and the labor is included with the price.

Got the ECU tuning done today. It was quick and painless. They hookup a laptop to the car and they start uploading the data and it's done within 30-45 minutes. The total came to $2599.03 after everything. There was no labor costs but there was a charge for some part at $29.

The car seems lighter and more agile. The pickup is just amazing, although I did not get a chance to drive it on the highway. I didn't really get to drive the car that much today but I am driving out to Daytona Beach tomorrow and I will really get to test out the new power.

I would highly recommend the upgrade. It is like spending $2600 and basically getting into a newer car.

Had the software mod done on my 2009 750i today at the Dinan dealer in Glendale CA. Haven’t had the chance to get on it yet. You can definitely feel a big difference and the shifts seems smoother etc…However, I have noticed that the car is running hot and the temp outside was only 68….Needle was sitting on the 2 of 250 and I could tell that if I was to get on the throttle that it would keep moving.

I have no doubt that Dinan – as they did with the 335 will have to come out with a larger oil cooler for the 750.. For now I am trying to find out if the oil cooler for the 760il has a higher oil capacity, hence the greater ability to keep my engine cool.

Also, I have heard that there is a “ hot weather package” just not sure what it comes with…any ideas?

The funny thing is, I have to drive a lot and on the day that I actually look forward to it, I couldn't and I was stuck in traffic for the most part!!! I couldn't wait to get out of the dealership and get it on the road.

Anyway, I am driving out to Daytona Beach in a little bit and it is two and half hours each way so I will be making up for it. Will update tomorrow.

Awesome, its good to know that they are still focusing some effort on the F01 and not devoting 100% of their time to the F10. Obviously most of the parts would work either way though I guess.

I think, you will always have hotter engine temp after Dinan Tune (compare to standard factory tune 750i engine temperature)
unless you change your cooling system to Alpina B7 spec.
I also want to point out that an F01 7 series is heavier than an F10 5 series.
So the same engine in a F10 5 series will have to work less (less weight to move) compare to the same engine in F01 7 series.
That mean an F01 7 series will always work harder and create more heat compare to the same engine in an F10 5 series.

Based on the horsepower increase Dinan's claim after their software modification, we can see that it is very close to Alpina's B7 horsepower !

and an Alpina B7 had this extensive modification to manage the extra heat from the extra power :
1. Bigger Radiator and Additional Radiator
2. Bigger hose that connected the radiator, water coolant pump and engine block.
3. Larger Capacity Intercoolers (3 air to liquid intercoolers)
4. Higher Blowing FAN (radiator fan)
5. External Transmission Oil Cooler and Rear Differential Cooler
6. Additional Engine Oil Cooler
7. Larger Turbo Charger which mean they are able to pump higher boost
with less strain compare to stock turbos (less heat too).
8. Higher flowing Exhaust to make sure the hot exhaust gas get out faster.
9. Front Spoiler that had been designed to channel more cooling air towards the radiator and intercooler.

Here is an article from a magazine that contain a nice pictures of
Alpina B7 cooling system:

Took the car for an extensive ride yesterday and the temp never went above 220... This isnt to say that on a hot day there wouldnt be issue. I also got a call back from the dealer and they said that the 760il had the same oil cooler as the 750i...hmmm v12 vs v8 and same cooler? Thanks for the update on the Alpina cooling specs.

So how did the new power feel? Any stronger at any particular speed range?

Hi Dovi23,
you also need to remember that the V12 have their turbos in conventional location, while the V8 have the turbo between the cylinder banks, and together with the exhaust manifold which mean more enclosed and thus hotter.
that is probably the reason why 750i had the same oil cooler as the 760iL.
the 760iL is also a larger displacement engine, so the engine is not as stressed as the 750i engine, that mean the V12 run at a lower temperature.
but I strongly recommended that you upgrade your FAN (radiator FAN),
the the 760iL fan, because if I am not mistaken,the Alpina B7 use 760iL Fan. I think that is the easiest and cheapest upgrade to increase your 750i
cooling efficiency.

here is an interesting article:
and on the article below take note on this sentence, where the hot turbo can cause the paint on the hood to peeled off !
(Auto makers have experimented with the concept for years, but until recently were fearful. "They were afraid of overheating turbochargers, overheating the entire engine compartment. We know of cases where the paint on the hood (of a test vehicle) peeled off.")

Turbo Placement on BMW V-8 May be New Design Trend By Drew Winter
WardsAuto.com, Jan 28, 2009 10:28 AM Critics who think the V-8 engine is a bloated dinosaur headed for extinction should take a close look at BMW AG's new twin-turbo 4.4L in the X6 and upcoming 750Li.
Efficient and capable of meeting Euro 5 and U.S. ultra-low emissions (ULEV) standards, experts say the new engine also is capable of producing far more than its current 400 hp without breaking a sweat.

Environmental Protection Agency fuel-economy numbers are not yet available for the 750Li, which is due in the U.S. in the spring, but it is safe to say it will not threaten the Toyota Prius' lock on fuel-efficiency leadership. However, it is a plausible replacement for BMW's much larger, and thirstier, V-10 and V-12 engines.
The new gasoline V-8 has been downsized from 4.8L and replaces the effective-but-cumbersome Valvetronic system with direct fuel injection and twin turbochargers. The new design makes 40 more horsepower and 90 more lb.-ft. (122 Nm) of torque than the previous engine.
Most significantly, the 4.4L is extremely compact and generates a prodigious 450 lb.-ft. (610 Nm) of torque across a broad power band from 1,750 to 4,500 rpm. It is all due to a new design that situates both turbos and catalytic converters in the "V" section of the block, rather than the outboard sides of the cylinder banks.
BMW says the configuration is a world first for an 8-cyl. gasoline engine.
BMW says new 4.4L first 8-cyl. gas engine with turbochargers in "V" section of block. "The design is indeed unique, with the main advantages being higher performance (especially torque for a gasoline engine) and lower fuel consumption," says analyst Mike Omotoso, senior manager-Global Powertrain at J.D. Power & Associates, noting "600 Nm of torque at only 1,800 rpm is impressive. Those torque specs are what you would expect from a diesel."
BMW says the torque peak is about the same as delivered by the auto maker's 6.0L V-12.
For a Detroit comparison, Chrysler LLC's naturally aspirated 5.7L Hemi produces 376 hp and 410 lb.-ft (556 Nm) of torque.
Of course it was not just a matter of moving turbos to and fro. The change also requires a new configuration of the intake and exhaust ducts, BMW says. This, in turn, demands the exhaust camshafts and valves be placed inboard, so the path for the exhaust gas from cylinders to turbochargers is shorter. The intake camshafts and valves then are positioned outboard.


Dean Tomazic, vice president-Engine Performance and Emissions Div. at FEV Inc., an independent engine and powertrain systems research and development company, says all this rearranging results in three major benefits: better packaging, improved cold-start emissions and the elimination of turbo lag.
Moving the turbos from outside the cylinder banks to the center of the engine shrinks the powerplant's footprint and creates more room in the engine compartment for the steering column and other mechanisms that cause packaging headaches for vehicle designers, Tomazic says. It also eliminates the issue of installing bulky heat shielding on both sides of the engine to protect other components from the high temperatures the turbos generate.
Locating turbos and catalysts in the center of the engine also improves emissions, he says.
Turbochargers complicate cold-start emissions because they absorb exhaust gas heat and slow the time it takes catalytic converters to "light off" and reach optimum operating temperature. By placing the turbos and converters on top of the engine close to the combustion chamber exhaust ports, they heat up faster, providing cleaner emissions during startup.
The short path from exhaust port to turbine also minimizes heat losses and improves turbocharger efficiency.
The third benefit of a centralized turbo arrangement is what Tomazic calls "improved transient response," otherwise known as reduced turbo lag.
"A more compact exhaust system means minimizing the volume between the pistons when they push out the exhaust and the (turbocharger) turbine. With this arrangement you can't get smaller than that, therefore you have optimized transient response," he says.
Auto makers have experimented with the concept for years, but until recently were fearful. "They were afraid of overheating turbochargers, overheating the entire engine compartment. We know of cases where the paint on the hood (of a test vehicle) peeled off."
Now, the need to improve transient response and meet more stringent emissions standards is forcing auto makers to deal with the heat issues and move forward.
General Motors Corp.'s new 4.5L light-duty diesel, due soon, features a forced-induction system similar to BMW's. Tomazic predicts more turbocharged gasoline and diesel V-8s will use the centralized layout in the future, as well as V-6s.
Meanwhile, J.D. Power's Omotoso predicts the 4.4L will grow stronger. "There is speculation that the next M5 will use this engine instead of the current V-10, and an M5 with less than 500 hp is unlikely," he says. "I suspect the current engine in the (BMW) 750 and the X6 has been de-tuned to sacrifice horsepower in favor of fuel economy. Fuel economy is not really a consideration in the M5 and M6, so look for 500-550 hp in the next year or two."

ESS Tuning vs Dinan Tuning

I am new on here so hello BMW enthusiasts! I was thinking about getting the Dinan ECU flash for my 2009 BMW 750i. I was about to go ahead with it but found that ESS released some wild numbers for their flash. The numbers are nice but concerning. I snipped and pasted it below:

"ESS tuning software takes the 4.4l twin turbo to new heights, with breathtaking torque and gobs of silky smooth horsepower. The new V8 TT software gives power where its needed, BMWs line up of vehicles that offer this power plant are larger heavier cars and SUVs that need a increased low end torque to propel them to speed effortlessly and with up to 655 ft-lb ESS does just that!" - www.goodspeedperformance.com

I read elsewhere that the horsepower is up near 525! How is that even possible without further mods on the engine? I was thinking that they must have turned the pressure up to the max, but won't that blow the engine? On the next M, with this same engine, I heard rumors that the pressure will be up to 21, but I'm sure the M will have heavy mods. I would even like Dinan to comment on this one. What did ESS do to be able to claim that level of gains with just a flash? If I find out more I will post it on here.

My Dinan update and review:

Dinan did not give me an additional discount for my trouble only "local" dealer waived the labor charge. They did it for $2399 + tax out the door.

I had mine done Friday afternoon. As I am the first F01, F02 that my "local" dealer has ever dealt with, so there are some issues with the software downloading cable compatibility, they had a wrong ethanet cable to begin with, which won't download software, went out got a new one that worked eventually. But I have to wait more than 2 hrs. for the whole thing.

After getting the car back, I did feel the car is lighter. I don't know if it is my mind playing the trick or what. My highway experience was just so so, not black and white difference. That day traffic is an issue, unable to fully press the car. Since this car is already fast, so I don't really feel that much of the difference, maybe I need to drive more to feel it.

So, since I don't feel that much of the difference, how can I tell that the dealer really got the job done and get the job done right, other than a piece of invoice showing the painful balance?

There is another thing that dealer warned me about the software upload. For your future services, if there is any software upgrade to your car, it will overwrite the Dinan software, and you need to go to your Dinan dealer to redownload your software, it will be free but it will be really inconvenience for those who live far from Dinan authorized dealer like me.

For me the total experience is not worth of the effort and money now, maybe I will change my mind one day after smoke a MB AMG. Share your experience guys!
