    Tuners have flashed F-Series BMW models for some time now but they would require physical access to the ECU. That means you would have to remove your engine management computer and get it to the tuner somehow. After they unlocked it, you could flash it. Well, no more. The F-Series is officially cracked with OBD-II tuning. This means you can expect hand held flashing systems to come to market shortly. BimmerBoost will be detailing some of these systems in a subsequent article. Several tuners have contacted this site already on this topic: Expect this to spread like wildfire. For those keeping score, the Infineon F-Series ECU's were first unlocked in December of 2014. It took three years to go from there to OBD-II port flashing.

    This is what you can call a serious N54 build. @Ericbh77 is not messing around with his E92 335i. He is going for roughly 1000 horsepower and what is making that possible is the custom Fab Factory bottom mount twin scroll turbo manifold mated to a PTE 6870. The motor is obviously built and he is going with Schrick high lift cams: VAC built the motor and did some head work as well. He is planning on having @CKI@Motiv tune it and additional fuel is coming from a supplemental HPFP pump. Most high horsepower builds like this tend to be manual as the automatic will not hold the torque. Will this one? We'll see as it features upgrades although they have not been tested at this level. This is going to be a fun build to watch come together. Enjoy the pictures below.

    You know all about tuned Audi 4.0 TFSI V8's making monster power and torque in the C7 RS6 and C7 RS7 models. It is our duty at to never allow Audi to live down not bringing the C7 or C6 generation RS6 vehicles to the USA. Who in the world would hate an RS6 with 800 lb-ft of torque? Ok, 792 lb-ft according to this dyno but close enough. This is solely with the Stage I APR 4.0 TFSI V8 tune: An increase of over 220 lb-ft of torque will definitely help this wagon haul the family and luggage. On the bright side we have the RS7 with this same motor in the USA so all is not lost.

    Gintani is still tuning the project 991.2. This is a preliminary graph that gives you an idea of the difference the tune makes. Gintani believes they can add a little bit of power up top but as you can see this motor is a torque monster down low. Compared to GIAC's 91 octane tune Gintani does not ramp in the torque as hard down low but the peak comes at about 4200 rpm compared to 2950 giving a broader curve: The torque increase is 110 lb-ft over the baseline but for whatever reason the baseline is a bit lower than it was on other Mustang dynamometers while the peak horsepower is right on the money. The dyno was recently calibrated. Gintani is still tuning so take this as an early result but obviously there is a lot on tap from the stock 991.2 Carrera. Additionally, dyno results with cat bypass pipes from Soul Performance should come today and Gintani also plans to do a race gas tune which thus far nobody has done.

    You already know the N54 turbo upgrade market is crowded but in 2017 bottom mount options with Borg Warner EFR turbochargers became more prevalent. VL Performance is entering this niche and gauging market response. So what is special about their approach? They are packaging their manifold with the largest Borg Warner EFR turbocharger (9174) available. It has an external wastegate and although we only have one teaser pic to go by it certainly does look to be well packaged and designed with the room to work with. What does it cost? When will it hit the market? Will it hit the market? All valid questions we will hopefully get answers to.

    This E82 135i used to belong to BimmerBoost member @trickcruiser. He sold it but here are some final dyno pulls from his ride. This is a stock head and stock block N54. It is running a Precision 6466 single turbo with a VM N54 manifold. Going beyond this power and torque for a daily driven automatic N54 is asking for reliability concerns: The transmission was rebuilt by Level 10 but they have mixed reviews to say the least. Look to them more to refurbish an auto box than anything else on the platform. A solid 637 wheel horsepower and 533 lb-ft of torque in street trim on an E85 tune. The fuel system is a Fuel-It! Stage 3 with port injection and a BMS controller. It will be interesting to see if the new owner intends to push it much further.

    Carwow got their hands on the new F90 M5 and did some GPS testing. First, keep in mind that these are not real dragstrip times. Secondly, keep in mind it is Carwow who for the life of them can not figure out what a trap speed is. They get a 0-60 time of 3.1 seconds and 11.1 seconds for the 1/4 mile. They say this is 'faster' than the Mercedes because they got an 11.2 out of it. It is quicker, not faster. Well, this is just overall poor testing. For one, the Mercedes was tested in different conditions. Two, no trap speeds. Also, since this is not done on a dragstrip we can not compare 60 foot times to see how the launch affected the elapsed time. Why are they not going to the hundredth on the times either? Overall since this is very early in the lifespan of the F90 M5 we are hungry for whatever metrics we can get. Is the F90 M5 quicker and faster than the Mercedes-AMG E63 S? Probably. They are likely so close that if you want to win you need to make sure you have a tune. In that respect, the AMG starts out ahead of the M5 just as it did last generation.

    As you likely know the big news this week was that OBD-II port ECU flashing is now possible with BMW F-Series models. This is big as owners no longer have to remove their ECU's to send in to tuner for manual unlocking which opens up major possibilities. Let's start with models are supported by the @MAGICMOTORSPORT system and the basic requirements: Supported vehicle models: BMW: F01, F02, F06, F07, F10, F11, F15, F16, F18, F25, F26, F30, F31, F32, F34, F36, F80, F85, F86 Mini: F55, F56, F57 Supported engine models: BMW: N13, N20, B47, N47, N55, S55, N57, N63TU, S63TU (excludes only: B48 and B58) Minimum requirements: PC requirements: MCU: Dual Core i3 RAM: 4GB OS: MS Windows 7,8 or 10 x32/x64 Ports: 1 x USB2.0 port, 1 x RJ45 Ethernet port Network: mandatory internet connection (the IP address of the PC must be assigned by the DHCP server) Vehicle requirements: Battery recharger required min. 50A Most F-Series engines are supported except for the new B38, B48, and B58 motors. That is a long list of models and motors so why are we putting this post in the S55 section? Because BimmerBoost knows of a tuner who will be using the Magic Motorsport handheld flasher to tune an F82 M4. We intend to bring you those results as soon as write mode is enabled after December 24th. Think of it this way, once the tuner complete their tune in theory they could send you that tune and you could flash your own M4 right at home. Now you see just how big of a deal this is. How much is the system? European pricing is 1900 Euros: Expect US pricing from dealers soon. Keep in mind there are several features supported: The big one there is the CVN fix. What this does is it makes it impossible for the dealer to know your ECU was tuned. Very nice for those who want peace of mind with potential warranty issues. Expect more details as the flashing tools get out there later this month.

    Gintani continues to tune the Project 991.2 911 Carrera and now has the car over 440 wheel horsepower on their Mustang dyno. Compare the race gas figures you see in the graph below to the preliminary 91 octane pump gas tune only numbers. The car has Soul Performance cat bypass pipes on it now but a dyno overlay of just the pipes will come in a subsequent article. For now they are still working on the race gas tune and they got the car over 450 whp but are still tweaking various aspects. You will notice a bit of torque was lost down low but this is a trade off for top end gains. Essentially, we are at another 22 wheel horsepower. There is also a nice mid-range gain from 4750 rpm to 6000 rpm. Past 6500 rpm the turbochargers just run out of steam. 991.2 Carrera S turbos might provide another 20 whp or so but 991.2 GTS turbos would really give a nice bump up top. It looks like it is time for a turbo upgrade. For context, 440 wheel horsepower on a Mustang dyno is roughly stock Porsche 991.1 Turbo S power:

    Congratulations are in order to @NJ-M4 for setting the new overall quickest and fastest Porsche 991.1 Turbo 1/4 mile record! He ended up breaking his own quickest record which was 9.70. He picked up quite a bit of trap speed though and his 147 trap is now the fastest recorded in the USA as well. The previous fastest pass was 9.71 @ 143.80 by @Markblackwell. Here is the mod list: Mods (chosen and installed by AIM Performance): ESMotor 71mm VTG Turbos ESMotor intercoolers AIM Lightweight Exhaust ESMotor headers IPD Plenum IPD Y pipe meth kit Lightweight Tecnocraft seats OZ Wheels Cobb tuned by @Emre@Esmotor There is a bit of weight stripped out as the carbon Technocraft seats are extremely light. EDIT: He further improved his quickest record to 9.59: Everything else is pretty much as it was with the ESMotor Turbochargers and tuning doing most of the work. What is impressive is this car is still on the stock motor as it approaches 150 traps. Also the stock transmission with the stock clutches. Yes, really. Congratulations again to @NJ-M4!

    The new 2019 Corvette ZR1 LT5 motor illustrates the point well that direct fuel injection on its own is not the best choice for a performance car. You will notice an increasing trend of high performance cars coming to the market with dual fuel injection. That means both direct and port fuel injection systems. Why both? Because direct injection quickly becomes a liability. The technology spread due to efficiency benefits not because it was better for performance. Want to disagree? Tell it to McLaren who for some reason opted not to equip the McLaren 720S M840T V8 which is absolutely vaporizing all challengers with direct fuel injection. The issue is not only do you need strong pumps capable of huge pressure the injection window shortens with RPM. That makes it a challenge to provide enough fuel at higher rpm ranges. This is exacerbated as power as added. Let's assume for a moment you buy a Ferrari 458 which has a direct injected motor that revs to 9k rpm. You might be saying, what is the problem? Well, try running ethanol through the motor. As ethanol contains less energy than gasoline while at the same time offering higher octane and cooling benefits you need to flow more of it through your fuel system. The direct injection system quickly taps out. It only gets worse if you add power. Port fuel injection does not have the same injection window or pressure issues. This is probably why McLaren does not use it on its 8000-8500 rpm motors. This is probably why Ford does not use it on the 8200 rpm GT350 Voodoo V8. This is probably why BMW M did not equip the S65 V8 or S85 V10 8250+ rpm screamers with direct injection. Manufacturers building performance engines today with direct injection are increasingly offering dual injection systems with port fuel injection. Why? To alleviate stress on the direct injection system and offer fueling headroom say with modern ethanol blends. It also reduces carbon deposits. There are pluses and minuses to both approaches. Direct injection allows motors to run at higher compression before detonation on pump fuels. This obviously provides a power and efficiency benefit. The cooling effect of direct injection is due to fuel droplets going through a phase change from liquid to gas and becoming an ignitable vapor that can be mixed with air and detonated by the spark plug. Heat is absorbed during this change providing a cooling effect which will allow a direct injection motor to run leaner. Again, this provides an efficiency benefit when it comes to fuel use. Port injection allows air flowing through the intake manifold to cool before reaching the combustion chamber while direct injection provides its cooling benefit in the chamber itself. Port injection also does not require the high injection pressure and it does not have the limited injection window which means it is easier to flow far more fuel. You can see how combining these two technologies provides the benefits of both and minimizes the downsides. Just look at the performance motors that recently entered the market with dual fuel systems: Chevrolet LT5 Audi 2.5 TFSI Audi/Lamborghini 5.2 V10 Bentley W12 Ford 3.5 Ecoboost There are other motors with dual injection not listed there but you get the idea and more are on the way. It is interesting to note that many enthusiasts on the various BoostAddict sites with direct injected motors who add power look into adding supplemental port injection systems. It is ironic that getting away from port injection quickly leads them right back to port injection once they start to add power and run ethanol. Factory dual-injection tends to provide the best of both worlds.

    Well, holy crap! 8's out of the box? A 250 mph top speed? That is not all. The new Tesla roadster is said to hit 60 in 1.9 seconds and it will hit 100 miles per hour in 4.2 seconds. Those numbers are so mind numbingly fast please excuse us for being skeptical. When will it hit the market? Apparently it is being positioned as a 2020 model year car. The battery capacity is said to be good for 630 miles. Three motors will supply over 7,000 lb-ft of torque. It will start at $200,000 which for the numbers Tesla is quoting is well worth the money. Hell, it's worth double. It is going to be very hard to argue against the new Tesla Roadster if it delivers as advertised. The only downside will likely be the heft.

    MotorTrend got their hands on these two German hot rods featuring 3.0 liter twin turbo powerplants. The engine design is quite different however with the 911 GTS 9A2B6 featuring an oversquare flat-6 and the M4 S55 featuring an undersquare inline-6 which BoostAddict previously covered in an engine design comparison article. That said on paper these cars match up well. The M4 obviously offers greater value but it is heavier and seats four adults. The 911 does not seat four adults but is roughly 200 pounds lighter and of course more expensive. Power is essentially a wash on paper but we really need to see them both on the dyno to know the truth regarding torque curves, spool, and output. Unlike BMW who just changes software for the output gain, Porsche gives you larger turbos with the GTS. This GTS is rear wheel drive just like the M4 and both have dual clutch transmissions so this is as apples to apples as we are going to get. Ok, let's get to the actual performance comparison! They get the cars out on the Nurburgring and how can you not love that? Well, they ruin the whole thing by not providing laptimes. WTF is the point here guys? You attend a track day, talk about factory laptimes, and provide no actual performance measures. MotorTrend should never be allowed to take cars on the 'Ring again. What happens after the big Nurburgring buildup that ends in a whimper? They go on some damp and foggy mountain road and continue to yammer on about their feelings. Where is the Head 2 Head performance comparison gentlemen? You might as well have grandmothers compare these cars. What a waste of time MotorTrend. Don't call it a Head 2 Head comparison when really it is just story time with Jonny Lieberman and some guy who has an English accent which obviously means he has to know cars. You guys are a joke.

    There is a big difference between getting an OTS (off the shelf) and pro tune. The pro of course standing for professional. Why is there this difference? Because a pre-packaged or canned tune is designed to be one size fits all. It is also designed to be safe for different fuel qualities and cars around the globe. Do not get us wrong, PTF's (Pro Tuning Freaks) OTS Stage 2 S55 tune is solid. It will push an F80 M3 or F82 M4 into the 10's in the 1/4 mile. However, look at what a competent tuner (HCP) is able to extract with a custom pro tune over the OTS tune: A significant difference there, right? We are talking about 56 horsepower at the wheels. Keep in mind there will be less leeway. This tune is now custom tailored to that M4 and its fuel quality as well as other modifications. The truth is if you can afford it, getting a custom dyno tune is the best way to go. Think of it like having a tailored suit versus one size fits all.

    Sport Auto got their hands on two of the world's best track cars and took them to the Hockenheim in Germany for a laptime comparison. You may remember that the Lamborghini Huracan Performante briefly held the Nurburgring production car laptime record. That was until the 911 GT2 RS took the Nurburgring record with an insane 6:47.3 laptime. How do they fare on a smaller track going head to head in the same conditions? Like this: The GT2 RS time is out of this world. It did not just beat every other car Sport Auto tested it crushed them. That includes the Huracan Performante which is the second quickest they have ever tested. Porsche did not pull any punches. They set out to build the world's top track car and they succeeded.
