    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.

    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.

    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.

    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.

    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.

    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!

    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:

    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.

    The N54 turbo upgrade market is seemingly flooded with various 'cast' upgrades. It is somewhat tough to sift through all the options and determine which are worth the money and which are just cheap junk made from 'chineseum' material. The MMP upgrade sure looks to be worth the money. Mauricio over at @MM Performance has worked on these turbochargers for quite some time. They are coming together very nicely. BimmerBoost last wrote about this upgrade in July, 2016 where the bang for the buck aspect was touted. Since then the market was flooded with cheap cast options many of which are from overseas. The MMP option sure looks good at this stage: Beautiful, right? So how far away are we from them actually being for sale? The question remains, is this the best cast N54 turbo upgrade option on the market? We will know the answer very soon.

    This BMW E92 335i belongs to BimmerBoost member @PureEvilN54 and he recently swapped a DCT (dual clutch) transmission into his 335i. Pulling off the physical swap is one thing but he states he is able to get launch values others are not. For example, 3500 and 5000 rpm launches. In the video below he demonstrates a 3500 rpm launch that builds 4 psi off boost at the line and he tells BimmerBoost that thus far he is the only one doing this launch control RPM value on a DCT swapped N54. BimmerBoost would love to see confirmation of that 5000 rpm launch.
