    The time has finally come to share some details on my secret N54 project. It's been under development for many months now, and had no shortage of both hardware and software (mainly software) obstacles to overcome. That said, a major milestone was reached this week so it's time to let you all in! Coming soon to a stock DME near you: Yep, real Flex Fuel. It is a fully implemented flex fuel solution, running on the stock DME! Dial your car in on pump (91-93oct), then E85, set the blending / interpolation curve tables, and be on your way. The benefits here are never having to reflash when changing ethanol blends again (or even worry about mixing the correct blend). Go from straight 93oct to 100% E85 or E98 on the same flash :) This is up and running on a few IJE0S cars now and works flawlessly. There is still some more work to be done, and of course porting to the other ROM types will take a good bit of time. Some hardware details are in need of finalization as well. More to come on those items in the weeks to follow. Some overall highlights and features of this accomplishment: first DME integration with a 3rd party sensor first large scale rewrite and modification of DME logic direct logging of Ethanol Content % in MHD separate blending / interpolation per table grouping seamless blending between maps for any ethanol content I'd also like to give a big thanks to @Chris@CKI for his help in testing and flashing my countless revisions at all hours of the day, and also to @martial@mhd for assembly code and hex conversion help along the way! In case you haven't guessed, this will be a module available in MHD similar to M-Boost. A thread is worthless without pics, right? The log was taken after a fill-up to a higher E content, and you can see the AFR target rising as E% goes up. 2017 is just getting started, and will definitely be the year of the stock DME ;)

    An interesting upgrade option for N54 fueling is Fuel-It!'s bucketless LPFP. They have designed a special pick up that allows for their bucketless design. There are advantages here as for one they eliminated the need to modify the factory bucket and they provide a large increase in flow. Fuel It! describes the premise best: There were concerns regarding fuel flow when almost empty but this video addresses those concerns: Now let's look at some dyno results on an E82 135i N54 paired with their Platinum Port Injection kit: That is a solid 600 wheel horsepower with Pure Stage 2's and the AFR is 11.9:1 on an E53 ethanol blend. Definitely something for those looking to upgrade their fuel system to look into.

    There is a lot of intake manifold talk on the BimmerBoost forums as of late but there is little in the way of concrete results showing an increase in flow with aftermarket manifolds. EOS (Evolution of Speed) has some results to share with their V2 N54 manifold on a single turbo car. It is important to note that this car makes over 500 horsepower to the wheels with the factory manifold. For N54 owners to see gains they will have to be making a bit of power as the factory manifold is not a huge restriction. At 22 psi of boost the baseline shows 524 wheel horsepower and 515 lb-ft of torque at the wheels. You will note the factory baseline (red) produces substantially more torque from 3000 to 4500 rpm. With the EOS manifold you see a gain in peak horsepower but a drop in peak torque. The EOS manifold is showing an advantage from 5500 rpm until redline which is what produces a gain of 25 peak horsepower. The torque figure drops to 486 at the wheels however. Is it worth giving up some mid-range for top end pull? That depends on the application and goals. More testing is definitely needed on various N54 applications before reaching any definitive conclusions just yet.

    Rod bearing wear issues in the 4.0 liter S65 V8 in the E9X M3 are well known. Rod bearings also wear prematurely on the S85 V10 on which the S65 V8 is based but do to the superior oiling system of the V10 the problem is not exacerbated as it is on the V8. Things vary based on use as well. A car that is tracked or supercharged will see more wear than a stock car used for commuting. The bottom line however is that owners should replace their rod bearings before it is too late so that they can avoid what is pictured below. @Michael@GermanAutoWerks shared pictures of a blown S65 V8 from an E92 M3: Unfortunately, BMW has a history of mistakes with M3 engines dating back to the E46 M3 S54 and all the way up to the current F80 M3 S55. Someone should hold BMW accountable for knowingly selling motors with defects.

    Talk about entering the M157 scene with a splash! Pure Turbos is not messing around. The proof is in the results right here on a W212 E63 AMG. This is a 4Matic all wheel drive car as it is the facelifted version. In the 26 to 27 psi range of boost output is 840 horsepower. This is with custom ECU dyno tuning from Precision Tuning. Precision did not push the turbos as far as they could to preserve the driveline. What would these turbos make when pushed with an upgraded transmission? Good question. Oh, and how about the pricing? $5995 plus core exchange. That is the best turbo upgrade value in the M157 world right now. As a reminder, before the turbo upgrade and with bolt ons this E63 ran 10.6 @ 133. That was at 670 all wheel horsepower. What will it do now? We can't wait to find out.

    I have a highly modified 2013 C63 P31. It is currently making 525 RWHP on a Mustang dyno on 93 Octane here in CT. I am looking for a cam replacement, currently running stock ones, and hoping for 20RWHP. Does anyone have any experience with a cam swap? I am currently looking at the Kleeman cams.

    MFactory Competition Products / YCW Engineering are proud to announce our status as a newly appointed Master Warehouse Distributor for SWIFT Springs in the US, Europe and Asia We have available their full range of products including: - Sports Springs / Spec-R (To be used with stock dampers) - Replacement Coilover Springs (Upgrade your sagging coilover springs) - Assist/Helper Springs (Setup the droop on your coilovers) THE SWIFT ADVANTAGE: When drivers look at a set of springs, they concentrate mainly on the rates, but the material and manufacturing process is equally important. Most enthusiasts will tell you that all springs are the same... we asked some professional drivers for their opinions: - I just replaced my springs to Swift Springs with same spring rate, and somehow the car behaves totally different now. - Since I've swapped the springs from another brand to Swift, my lap times became very consistent throughout the entire race due to cooler tire temperatures, which saves tire wear. - We have tested our Swift-equipped race cars on a shaker rig, and the Swift Springs have a lot less harmonic vibration. - My car is a lot smoother with Swift Springs even though same spring rate were chosen, especially on bad surfaces. The many positive comments Swift Springs receive would have you believe that Swift Springs is surprised to hear such things in the first place, we are simply getting confirmation that our engineering not only works on paper, but is also proven through use in the field (track). Now, allow us to provide a few reasons as to why we get this kind of feedback from our users. PRIORITIES THAT WE ALWAYS HAVE IN MIND WHEN WE DEVELOP SUSPENSION SPRINGS: Surely you have read some spring manufacturer's catalogues before, and you have read that they all claim to have the 4 factors listed below. - The most consistent spring rate throughout the stroke - The largest amount of stroke - The highest durability against loss of spring height - The lightest in weight We like to believe that all suspension spring manufacturers try their best to achieve these 4 factors. Top suspension tuners know that these 4 factors play an intricate role when considering the effectiveness of the suspension coil spring. Our parent company, Tohatsu, has been winding industrial springs since 1924. Tohatsu then decided to get in to the auto racing market in 1996. Based on long-time experience dealing with coil springs, we came up with one goal: "We must make the product that will revolutionize the ones we see on the market now." Keeping this goal in mind, we went back to the basics of coil spring design and asked ourselves what is the most important factor that we need to consider on this new project. The answer? MAINTAINING TIRE GRIP IS THE KEY TO FASTER TIMES AND SUSPENSION SPRINGS TAKE ON AN ENORMOUS PORTION OF THIS TASK! All Springs are not created equal, the diameters and spring rates can be similar, but the process of manufacturing springs plays a huge factor in how they will perform. Through our extensive knowledge in performance springs, we have perfected the process of manufacturing springs that will outperform our competitors. With this in mind, we set out to produce a new material for coil springs: a proprietary steel alloy we call "HS5.TW". This material was created in order to maintain the 4 factors listed above, as well as achieving the fastest reaction speed possible to get compliance on road surface conditions. Our springs are created with proprietary winding methods, as well as some other trade secrets focused on ensuring our springs separation from the standard market. In the time since Swift Springs officially opened its doors in 1997, Swift Springs has dealt with many world class race teams in multitudes of different races including road racing, rally, off road, drift, autocross, pavement and dirt oval track, motorcycles, and more. Swift Springs has lifted many racers to a podium finish, and is still continuing to do so. With so much experience behind us, we feel confident that our springs will give you a leg up in any kind of race you participate in. Try Swift Springs on your vehicle, and experience what many racers are talking about. We strongly believe that you will feel the difference just like every other racer, and you might even wonder why you didn't try it sooner. THE HISTORY: The origin of Swift Springs Swift Springs was founded in 1997 in Tokyo Japan as a motor sports division of Tokyo Hatsujo Manufacturing Co, Ltd. that has been leading the spring industry since 1924 The purpose was to demonstrate our superior engineering in spring by developing the next generation of motor sports suspension coil springs. They had to have the best characteristics of any brand or design in the market, which required the springs to be the lightest in weight and most durable, and to exhibit the most linear characteristics while still being cost effective. Since the formation of Swift, it has been lead by the former racer and suspension expert, Kei Yokota, and the chief engineer, Yasu Saito. Their first-hand involvement within the race industry has propelled Swift quickly through the ranks of some of the world’s most reputable races. Swift springs quickly became one of the most recognized and respected name in performance coil springs in many genre of motor sports throughout the world. Being a part of the Tokyo Hatsujo spring corporation. Swift has a large collection of engineering research and development resources. Tokyo Hatsujo springs are used in most light to heavy industries and the dynamic has provided Swift with most advanced spring technologies and innovations available. In Swift’s impressive motor sports history dated back to 1998, first was with Nissan Skyline GT-R in the Super Taikyu Endurance championship series in Japan. Then Swift got involved with the championship teams in Le Mans 24hrs, Nurburgring 24hrs, Super GT (JGTC), Super Taikyu series, D-1 World Grand Prix, F3, F3000, Formula Toyota, and many other world class races. In 2004, Team Goh Audi R8 won 1st place at the world renowned Le Mans 24hrs race on swift springs.

    This E90 335i belongs to BimmerBoost member @idratherbesurfing. He has a top mount single turbo N54 conversion and is running a Pure Turbos 62mm turbocharger. He is still fine tuning the setup but it is already good for 680 horsepower to the wheels. At 30+ psi he believes he will crack 800 wheel horsepower: This is the mod list: Top mount twin scroll manifold Pure Turbo 62mm 1.0ar w/ 2 tial 38mm wastegates Ade motor mounts Vrsf chargepipe, Turbosmart bov, Vrsf 7inch fmic Fuel-it port injection, fpr kit, stage 3 lpfp MFactory lsd Mhd/Haltech stack Bms, Rb, and mishimoto catch can stack Tuning is a flash and piggyback stack with Precision Tuning doing the ECU flash work on their dyno. Take a look at the dyno vid below which is well worth your time.

    Uh oh, this has to be a warning sign at BMW. A drop of 10% in sales in 2016 compared to 2015 is large. BMW's are selling obviously as 313,174 cars is a lot of volume but that number was 346,023 in 2015. Perhaps the signs were there early in the year when Mercedes and Audi started the year with much stronger sales than BMW. Perhaps consumers are getting tired of BMW? Perhaps BMW has lost some of the enthusiast market? Keep in mind BMW equates sales figures with how well they are doing. They feel if they are number one in sales that means they are the number one brand. It's illogical as volume does not equal quality but that is the official BMW brand position. Just because one brand outsells another does not mean it builds better cars. For BMW this must be a bit of a shock considering how hard they are trying to push volume above all else. That is why you have so many variants of platforms namely in the X-Series line. Additionally, the new 7-Series launch should have further bolstered the bottom line. Table 1: New Vehicle Sales BMW of North America, LLC , December 2016 Dec. 2016 Dec. 2015 % YTD Dec. 2016 YTD Dec. 2015 % BMW brand 32,835 34,625 -5.2 313,174 346,023 -9.5 BMW passenger cars 20,419 22,818 -10.5 209,231 244,767 -14.5 BMW light trucks 12,416 11,807 5.2 103,943 101,256 2.7 MINI brand 4,658 5,009 -7.0 52,030 58,514 -11.1 TOTAL Group 37,493 39,634 -5.4 365,204 404,537 -9.7 When Mercedes and Audi release their figures we will know if either or both of them took the crown from BMW in 2016.
