    This information comes to BimmerBoost courtesy of one of our tuning vendors. Based on a discussion with the tuner they have stated they have the ability to flash the S55 DME. As you may know, tuning modern turbocharged BMW's through the factory engine computer is proving difficult as BMW has tremendously upped encryption of the engine computers and is cracking down on any internal sources leaking codes to tuners to flash the ECU. Even vaunted BMW tuners with deep pockets such as Dinan are forced to resort to piggyback tuning due to the difficulty of gaining access to the modern BMW ECU's. Tuners with some of the best software engineers in the business such as COBB Tuning have stated that the encryption level of the F30 3-Series ECU is government security caliber. COBB has been working for some time now to try to get access to the F30 ECU and there is no telling if they will be able to. That is why this piece of news comes with some reservations as the tuner did not state how they were able to get access the S55 ECU in the F80 M3 and F82 M4. It certainly would be astounding for a crack to come this quickly as the car just hit the market. BimmerBoost is waiting on further details as the tuner makes preparations to make this software available. As soon as we get the concrete proof rest assured BimmerBoost will bring it to you ASAP.

    The E30 M3 released in 1985 was designed with DTM (Deutsche Tourenwagen Masters or German Touring Car) racing in mind. The S14 four-cylinder under the hood was designed for professional racing (as M3 engines traditionally have been) where it excelled. The S55 turbo 3.0 liter inline-6 in today's M3 is obviously a much more powerful motor. It is larger than the 2.0-2.5 liter S14 four-cylinder and also turbocharged whereas the S14 is naturally aspirated. The difference on paper is close to 100 horsepower but in practice it is closer to 200 horses as the new M3 is severely underrated. Horsepower is only one part of this story as the E30 M3 DTM car is much lighter and stripped out for the track. The weight difference is in the 1000 pound range based on a 3562 pound curb weight for the F80 M3. Can a chassis design that is over three decades old now compete with a brand new and much more powerful M3? Yes. Not only does the 1992 E30 M3 DTM car compete with the 2015 F80 M3, it beats it around the track. Keep in mind that back in the 80's and early 90's DTM cars actually represented their production counterparts. The E30 M3 does a 1:09.1 laptime around the Hockenheim to the F80 M3 1:13.1. A four second difference which is simply stunning. The new F80 M3 is a great car but it hardly makes the classic M's obsolete. Namely on the racetrack which the BMW Motorsport division used to design their M3's for.

    We've got the Vargas Stage2 N55 turbo running on our 2011 135i DCT car and was finally able to hit up the dyno for a little tuning today. The vehicle is FBO but equipped with a CPE replacement catted DP. We've recently modified both the E series N55 ISO JB4 firmware for large turbo support and developed an entirely new back end flash. To enable the JB4 large turbo maps you just enable the 3.5 bar TMAP sensor using version 5.5 or later. This changes map 1 to 16psi, map 2 to 19psi, and methanol mapping as high as your turbo will take you. All with reduced taper to redline to let the larger turbo shine. Dyno testing was done on simulated 93 octane (91 + 1 can of NOS octane booster), and the methanol testing was done with a single CM10 nozzle. Overall very pleased with the results especially for an odor free vehicle. The pump map is a touch aggressive but really showcases what the turbo can do. On pump gas I think the car would come very close if not take our F80 M3 if the M3 is running the stock tuning. And on meth would come very close to the M3 on the E30 map.

    Great runs here courtesy of BenzBoost member Vasily1. We have seen his E63 AMG in action before. As a reminder, he has a prototype Renntech E63 AMG 4Matic M157 turbocharger upgrade on his car which is putting out something in the 850 horsepower range. We have seen some impressive performance from this car including runs with a Lamborghini Aventador as well as a supercharged C63 AMG and another tuned GTR. In this run video @Vasily1 takes on a PP-Performance Stage 2 tuned F13 M6 said to making 740 horsepower. In addition, a Nissan GTR with a quoted 700 horsepower is also in the mix. Thanks to multiple angles and good video quality we get a new view of the action. The M6 and GTR both put up a good fight. The E63 AMG S is the fastest of the trio though consistently managing to open up a gap between it and the other two cars up top. The only run the E63 loses is the very first one where the GTR gets the better start on it but the E63 starts reeling it in. As the other two cars are on stock turbochargers the power and torque advantage here clearly lies with the E63 AMG and it shows. That stated, the GTR and M6 do well against stout competition.

    Big news here from Weistec Engineering who has managed to keep their Mercedes-Benz McLaren SLR twin turbocharger development under wraps until now. The Mercedes-Benz McLaren SLR as you know has an M155K supercharged 5.5 liter AMG V8 which is based on the M113K supercharged 5.5 liter V8 familiar to us from the W211 generation E55 AMG. Weistec decided to remove the supercharger on the SLR and add a pair of turbochargers in. The Weistec SLR Biturbo system is still under development so few details will be shared at this time. What we can tell you is it will be officially released later this year. Additionally, Weistec will have M155K V8 built motor options with forged internals for those that want big boost. The system will be sold as a package. As far as power figures expect some eye opening numbers when the time comes. The Weistec SLR McLaren Biturbo System is the pinnacle of SLR performance. Cast Inconel manifolds flank the 5.5L V8, supplying ball bearing turbochargers and external waste gates with high flowing exhaust gases. These gases are then routed via 304 stainless steel downpipes, paired with aerospace grade bellows, and connect to the mufflers. The biturbo’s forced air charge is tri-cooled via an additional intercooler and cooling circuit working in conjunction with the factory intercoolers, allowing for high performance and consistency in any climate. Official Release Fall 2014

    Good news for owners of the new Volkswagen and Audi EA888 2.0 turbo motor. APR has released their tuning software for the engine which covers the 2014 up Audi A3 2.0 and the 2014 on MKVII Volkswagen Golf GTI. The software is flashed through the OBD-II port and has programs for 91 octane, 93 octane, and 100+ octane race gas. APR also bumps the redline up to 7100 rpm from the stock 6800 rpm. So what are the gains? The baseline on a MKVII GTI is 210 horsepower at the wheels. On 91 octane with the APR tune this rises to 281 horsepower on the wheels. 93 octane boosts power further with the APR tune taking the car to 291 wheel horsepower. The race gas figure is 303 wheel horsepower. APR did not take the tuned car to the drag strip but did some VBOX performance meter testing. Their 93 octane VBOX trap speed is 97.19 miles per hour. The trap rises to 110 miles per hour with the Stage I tune on 93 octane. This figure will be lower on an actual drag strip as the VBOX tends to read higher. Dynographs and an acceleration video below. Solid work as always from APR. 91 Octane: 93 Octane: Race Gas: Stock vs. tuned acceleration numbers and overlay video:

    Liter plus bikes are pretty damn fast, we know that. Power to weight tends to favor bikes at least stock. This bike is not stock however and is turbocharged putting out 425 horsepower at the wheels on C16. It is basically similar to riding a cruise missile. UGR (Underground Racing) makes some spectacularly fast cars with some of their twin turbo V10 Gallardo's and R8's rumored to be putting out well over the 2000 horsepower mark depending on who you ask. This Gallardo is stated to have '1750' horsepower. Based on a quick power to weight calculation it has around 1.94 pounds per horse. The Hayabusa based on a 425 wheel horsepower number and a ~600 pound weight with fluids and the turbo has 1.41 pounds per horse. The aerodynamics of course favor the Gallardo. So what happens? The Gallardo wins. Why? Well aerodynamics from a roll as stated and probably because it has more power than is being let on. Taking down a Hayabusa on the highway in a car is an incredible feat. A turbo Hayabusa? Well, that requires something truly spectacular. That is exactly what this UGR built Gallardo is.

    Audi and Porsche do not really like each other. They have to play nice as Volkswagen owns both of them now but Porsche and Audi each want to call the shots in the luxury segment. As Porsche expands its model lineup it continues to step on Audi's toes. Audi does not like this but Porsche also does not like that Audi made the R8 which definitely targets potential 911 buyers. Each company is taking offense with the other. This in-house battle is increasing as Porsche and Audi both are dumping money into competing platforms. Rather than cooperating each wants to push their own platform. Porsche wants Audi to use its platform for the next generation Panamera for example. Audi wants Porsche to use its platform developed for the next generation Q7 to underpin the Cayenne but Porsche is saying the platform has to many deficiencies including limitations with engine choices. Volkswagen wants everyone in the VW Group to use Audi's design to save costs. Lamborghini apparently is not too happy with Porsche as VW apparently is having Porsche design all the future sports cars in the VW Group. Lamborghini does not like what Porsche has planned for the Huracan successor. Audi who uses the Lamborghini platform for the R8 is also not happy with Porsche's approach so Lamborghini and Audi appear aligned against Porsche. Bentley on the other hand is happy with Porsche and their MSB luxury platform they intend to make use of. Lamborghini wants its own chassis and one designed to accept V10 engines. Porsche is building a chassis around their flat-6 motors which obviously benefits them. Audi uses the Lamborghini V10 so they are with Lamborghini on this one. See the mess? This is what a senior Volkswagen source stated on the matter, "If we don’t call the shots here at HQ, Audi and Porsche will never get their acts together. What these guys fail to understand is that they have to cooperate, not fight each other. We need to prevent individual sports car architectures and excessive proliferation, and to make Porsche’s MSB mandatory for both brands. Standardize the stuff that is really expensive: drivetrains, electronics, alternative propulsion systems, batteries, materials, methods, and processes. Audi and Porsche must stop fighting over architectures and concentrate on diversification by content. It’s as simple as that. And as difficult.” This is a bit of a mess but when so many brands are added into the mix and have overlap it is simply a matter of time before people butt heads. If VW wants to prevent this getting messy they need their executives to step in and dictate who will use what platform. That or they can let the brands compete against each other. Who really wants the same SUV rebadged seven times? It is going to be interesting to see what happens and how this is resolved. Source

    Very nice tuning results here courtesy of BrenTuning. The car in question is a 2007 W211 generation E63 AMG. This car has the naturally aspirated 6.2 liter M156 V8. The baseline with the charcoal air filters removed and airbox modifications is 415 horsepower to the wheels and 416 lb-ft of torque at the wheels. After the custom tune horsepower rises to 450 at wheels and torque goes up to 441 lb-ft at the wheels. These numbers are an increase of 35 horses and 25 lb-ft of torque respectively. Looking at the graph gains can be seen throughout the entire curve. The dynamometer used for the tuning is a Dynojet.

    Whether we like it or not the turbocharged modern era of Ferrari is here. It began with the California T getting a shared direct injection 3.8 liter twin turbo V8 design with Maserati. That same motor will be tweaked and find its way under the hood of the Ferrari 458. The turbo engines will not stop there as apparently a new 2.9 liter turbo V6 is in the pipeline. This information comes from Automobile who has absolutely no backing for their story. No quoted source, no official specifications, nothing. They seem to be guessing as they often do. Let's assume they are right for the moment and a new 'entry level' Ferrari is on the way. Ferrari does not want to dilute their brand image so a cheap car is out of the question. By cheap that means under $200k. Secondly, Ferrari's CEO is opposed to an entry level car. Where Automobile is pulling this information from is anyone's guess. This new car is supposed to be based on a compacted 458 architecture. The 2.9 liter twin turbocharged V6 would have output somewhere over 500 horsepower. This is all just a bunch of guessing though and Automobile admits as much: We do not have official confirmation yet, but intelligence indicates that the new twin-turbo V-6 is a 2.9-liter unit. Staying under three liters has serious tax advantages in China. Although the power output will be determined later in the R&D process, 500 hp and 440 lb-ft should be achievable. Do not get too excited as a lot can change and there is no official confirmation for any of this. Source

    Jaguar is very serious about the upcoming entry level XE designed to take on the BMW 3-Series and Mercedes-Benz C-Class. The XE will sport a lightweight and advanced aluminum architecture. Aluminum is nothing new for Jaguar who has been using the lightweight metal for some time now in their sedans and started doing so before most of their competition. What is interesting to note about the XE is that it will get an advanced suspension architecture inspired by the F-Type. This is great news as Jaguar's previous X-Type model that was intended to fill this same niche in the marketplace and also go up against the 3-Series was a letdown partially due to its Ford Mondeo inspired platform. Jaguar is not borrowing a cheap Ford platform this time. What they are doing is using their premium F-Type suspension components meaning the XE is shaping up to handle quite well. Along with the aluminum frame and state of the art suspension components a new lightweight four-cylinder 'Ingenium' engine family will be offered. Expect a 2.0 liter turbocharged engine although the horsepower and torque figures are not known at this point. Jaguar in a previous leak stated their supercharged 3.0 liter V6 would also find its way under the hood. The XE makes its official debut later this year on September 8th. The car is shaping up very well. Source

    It was just a matter of time and the Cayenne S is now officially ditching its 4.8 liter naturally aspirated V8 for a 3.6 liter V6 twin turbo borrowed from the Macan Turbo. The 3.6 liter twin turbo V6 has 400 horsepower in the Macan Turbo but Posche bumps it slightly with software for the more the larger Cayenne S. It still retains the automatic transmission whereas the motor is paired to a PDK transmission in the Macan. The V6 also gains 20 horsepower on the V8 it replaces. Torque gains should be considerably larger but Porsche has not published its torque figures for the Cayenne S yet, only the horsepower. If we go by the Macan Turbo the Cayenne S will have at least 406 lb-ft of torque. That means a torque gain of over 37 lb-ft on the V8 with the peak torque coming earlier in the rev range. More power, more torque, greater performance, and greater fuel economy. It's hard to argue against this move and it was inevitable considering Porsche already made the move for the 2014 model year in the Panamera S although with a 3.0 liter V6 and not the 3.6 liter V6 out of the Macan Turbo. It looks like all future four door Porsche S models will have turbocharged V6 power.

    I mean E30 off course. Argument stands. DTM Regulations. All 3 competitors use a 90 degree 4L V8 by regulation. BMW had to specially develop this P66 engine to be able to compete in DTM in 2012 You must be pleased to know that for 2016 DTM will switch to a 2L 4-cylinder turbo engine setup. How the F*** should I know what sports you can watch across the pond. It was a genuine question.

    M30? My point exactly. So the E30 M3 DTM car uses a motor you actually find in the E30 M3. It's irrelevant as you can't turn the M4 into a DTM car hence my point. What are you talking about? Of course I can watch DTM races. Not only can I watch DTM races in the USA DTM racing is coming to the USA.

    You know that this DTM version of the M30 is capable of Nordschleife times of 7min20 - 7min30 , right? No other M-car can do this, old or new. So not really a fair comparison. Nope, the P66 is a 4L V8 with air restrictors. DTM regulations do not allow a turbo engine I just was not prepared to go through the lists Is that what's bothering you? My guess is that this is just marketing from BMW. They want to plug the M4 to the German public. Rememeber the DTM races and race cars are primarilly targetted to the German public. They are supposed to buy the DTM lookalikes. Can you even watch DTM races in the USA?

    I agree for the most part but there are some well built LSX's or even BBC's that can rev past 8k with FI. However, to beat a high hp Lambo with RWD car, it is VERY VERY hard but not impossible IMO. Still, Lambos seems to be the best platform for high hp roll racing.

    A competition race car based on a 30 year old street car with which it shares all of its major components with, yes. How does this change the fact the engine is a naturally aspirated four-cylinder that comes under the hood of the E30 M3? Does the M4 DTM car use modified S55? No. Does the E30 M3 DTM car use a modified S14? Yes. The same Z4 GT3 that uses a modified S65 engine under the hood of an E92 M3? The same Z4 GT3 that has nothing in common with a Z4M as a new Z4M does not exist? You're insulting your own intelligence with this comment. Do these rules explain why we do not have a Z4M? Do these rules explain why BMW does not race the M4? Ya you aren't understanding that the Z4 races with a motor built for the M3 and that BMW does not actually produce a Z4 with that motor. I wasn't specifically referencing you.

    I know it is someone else's video. But you are comparing a full competition racecar to a modern street car. It is a fun comparison, but on a track where the racecar lives the streetcar will most likely lose, even to a 30 year old racecar. Not at all the same engine. Same bottom, yes Changes to the engine: gearbox, diff, gearbox & diff cooling, entirely different engine internals, large oil pan or dry sump, airbox & alpha N piggy back, later ECU4 and dual spark packs, 8 injectors, slide throttles, different radiator, different exhaust system Don't worry, I understood you. I just didn't understand your reasoning and how you got to that conclusion. BMW M's are still competing in lots of races. Look at the 24Hours of Spa Franchorchamps, where the Z4 GT3 lost by 7 seconds only to the Audi R8 LMS. Dunno. The list of changes to make them into rule compliant racecars on both cars is pretty long. DTM rules have changed a lot since 1990. The cars comply to these new rules. Duh? Race result 24H Spa Franchorchamps: 1 Rast/Vanthoor/Winkelhock (Audi R8 LMS ultra) 527 laps 2 Luhr/Werner/Palttala (BMW Z4) + 7.077s 3 Mies/Nash/Stippler (Audi R8 LMS ultra) – 1 lap 4 Guilvert/Ortelli/Sandström (Audi R8 LMS ultra) – 2 laps 5 Buhk/Götz/Jaafar (Mercedes SLS AMG) – 4 laps 6 Hommerson/Machiels/Bertolini/Cioci (Ferrari 458) – 7 laps 7 Smith/McCaig/Bryant/Sims (BMW Z4) – 7 laps 8 Wyatt/Rugolo/Lowndes/Piccini (Ferrari 458) – 8 laps 9 Schneider/Primat/Verdonck (Mercedes SLS AMG) – 9 laps 10 Abra/Osborne/Poole/Turner (Aston Martin Vantage) – 10 laps They are right there in between the other racecars... BMW also drives in the United Sportscar Championship, and other endurance championships I know it is just a comparison. Don't worry, I haven't been butthurt over anything on the Internet for many years. Maybe the reason why you are triggering all these reactions is because you (and Sport Auto) are comparing apples and oranges here.

Either way, being given this information 3-4 weeks ago is what lead us to immediately buying a set of M3/4 turbos, and pushing our F10 Stage 1 turbo upgrades up the todo list. We will be adding the N20 to the more pressing list as well.

    Quote from GSR - Yes, the ECU flash is real, this is not a hoax! No smoke and mirrors, it’s not a reported Yeti sighting… Hehe - Yes, the ECU flash is done via the OBD2 Port just as the factory would do it. - Yes, the Max speed limiter is deactivated (See Video Link on previous post) - Data Logs and Related Information: We will post more information in the coming weeks as we are currently developing tunes for the F10 M5, the GSR 228i Racing Project, the 650 and 740 non M Turbo V8’s, and the current Generation 35i engines. Please be patient as there is a massive amount of work involved in bringing these products to market utilizing proper testing methodology and validation processes. It is our goal to present the community with the best possible products that combine amazing performance with factory reliability. As you can imagine having an OBD2 Flash available for the current “Untunable” generation of vehicles is no easy feat. While we are new to this Forum, we are an established and respected company. We have a very talented and experienced team which brings unique technical capabilities to the BMW Marketplace.
