    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.

    fastgti69 started a thread VM Top Mount ST Dyno in N54
    Hey guys, sorry for the delay. I know you have all be waiting for this as we have too. Finally had time to strap it on the dyno. Here is the car with the mod list: E90 335i with VM Top mount ST kit, Comp 6465 Twin Scroll turbo. VRSF 7" Intercooler VRSF CP w/ Tial BOV BMS Meth kit w/ Two CM10 Nozzle 255 Inline pump Spec Stage 3+ W/ Steel SMFW Full Stock Exhaust JB4 with BB ST Flash We did some conservative tuning and testing, so these numbers are not even close to max. We used e40 Blend of fuel with 100%Meth. Tested to 26 psi and made 670whp 600wtq. Fuel trims and AFR are perfect where it should be at. We tried to up the boost but I guess that's as far as it can go with the 12 psi wastegate springs. That's the reason why boost starts to taper down near redline. We will redyno again in a couple of weeks with new WG spring and higher boost. Can't thank @Terry@BMS enough for helping us with our kit and tuning. There is no substitute when it comes to tuning your N54, Burger Motorsports is the best. Dyno, Log, and Datazap link: CSV file 26 PSI E40 Blend 100% Meth Dyno Log

    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.

    triggz started a thread Wedge Log vs V8Bait Log in N54
    Since nobody wants to post a log of Wedge's flash showing all 6 cylinders I decided to show the results. Car is running FBO+100%Meth+94 Oct. I asked Wedge for a Pump/Meth map and he sent me a map stating 12.5* of timing. I figured it's aggressive but safe based on my mods. I logged it and it looked great, BEFORE 6cylinder logging was available. Tested it out again and the results were not impressive. First off, it clearly shows the map is targeting close to 14* of timing which is way too much for 94/Meth. It's safe to say you need E85/Meth/FBO to run this type of tune. Now here is the tune I run on a day to day basis which is much smoother while cruising and the car responds well post shift. I'm sure if I dropped the additive to 50 from 60, the logs would be even cleaner or adjust auto shift boost reduction. Going for a dyno session this saturday and I will test Wedge's map with a 50 additive, 55 additive and 60 additive along with V8Bait's map 50/55/60 and see if the added timing really produces the results that everyone's butt dyno claims to be feeling. Just be careful what you guys are running out there. You can't just load a tune without logging. I'm sure Wedge's map could be adjusted so that it looks cleaner but he's so busy that I rather not waste my time. FYI, I NEVER had an ugly log with BMS maps. I personally think they are the safest and most reliable Bimmerboost maps you can use for your car.

    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.

    Hey guys, with the success of our LSD's (and upcoming final drives), we were interested in introducing more of our product range to the BMW market, and was just wondering if there would be a general interest in our other products: - 1pc Chromoly Racing Flywheels. Made from imported Japanese SAE 4140 Steel. These are Forged, Double Tempered and Super Sub-Zero treated for unsurpassed toughness, with a proprietary surface treatment for increased surface hardness - Hyper-Series Clutch Kits. Lightweight Stage 1 clutch kit with 6-puck sprung carbon metallic disc, coupled with our Racing Flywheel. Rated to approx. 400lbft. Image to come - Spherical-joint Front/Rear Camber and Rear Trailing Arms. These use our specially designed "sealed" spherical bearings, which have self-lubricating teflon lined inners (so do not need lubricating) and a genuine 100% seal from the elements; not just a cheap rubber seal that can be ripped off. Not only do these allow for full 360deg movement, essential in a race environment, they can also be used safely on the road without fear of binding due to the elements. Image to come - Racing Axles. Axle Shafts & 10% larger 6-Ball CV Joints are Forged from High-Nickel Chromoly Steel (300M) & put through our proprietary heat treatment process. Their hollow center shaft core (i.e rifle-bored) reduces rotational weight by 30%! Come with our full Lifetime Warranty Let me know if you have any questions :)

    In general, since we are all automotive enthusiasts here, I imagine we are all pretty good drivers. Sadly, that just means we are in the minority. I try to rarely complain, but I finally had to put together a list of my biggest frustrations while driving :angry-banghead: Agree? Disagree? Other additions? -Rich In priority order: 1. People who lolligag in the lefthand lane. After you pass, get back over. 2. People who don't secure their loads. See exhibit A. 3. Not understanding the proper way to merge. This includes both merging on to the highway, but also merging when lanes end say for construction. 4. Not passing a police officer/highway patrolman. It never ceases to amaze me the number of people who refuse to pass a highway patrolman, even when the officer is cruising well under the speed limit. I have to imagine this is some sort of game/stress reliever for POs - let's see how slow we can go without people passing us. :facepalm 5. Not turning right on red. I realize this isn't legal everywhere, but for the areas it is, for the love of God, turn when the coast is clear. 6. Tailgating. I hate tailgaters. 7. Rubber necking at accidents. Move along folks. Nothing to see here.

    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.

    Doing a single conversion on my 135i, so I'm selling off what I don't need now that the project has gotten a good start. (link in my sig) -RB Turbos for 135i - $2500 OBO Bought them new back in March of 2013, they have around 8k miles on them. I ran about 18psi, rarely any more than that. No leaks/smoke/issues out of them the whole time I've owned them. I made 478whp on my setup on 93 + meth. Upon removal there is no shaft play in them and everything looks fine except the wastegates do rattle a bit, but that should be easy to correct with adjustment. Once paid for, it will take me a day or 2 to get them shipped as I still need to source a box and packing materials. Honestly, I do not think they need to be rebuilt but I believe Rob does offer the service for $500 and I would be happy to send them directly to Rob if someone were to want to have them rebuilt. I will also take more pictures/different angles if anyone would like. -VK DP's - offer Used for 15k-ish. Fitment is ok. Doesn't include the o2 sensors pictured, or any bolts, fasteners, v-bands, or gaskets. Not sure what these are worth any more. Just shoot me an offer. -BMS DCI - offer Used for 15k-ish miles. In dire need of cleaning. Worked fine, even dirty. They are a little beat up from uninstall/reinstall. Just shoot me an offer, will have to see what these cost to ship.

    Well that was pretty fast. As reported last week the M3 / M4 S55 engine control unit has been cracked. Keep in mind this is very early in the flash tuning process of the new M3 and M4 but there are multiple tuners with the ability to flash the ECU out there with many more to come. Jailbreak Tuning posted the first Dynojet results of their flash tune and the result on 91 octane pump fuel is an increase of 20 peak horsepower at the wheels. Obviously peak horsepower does not tell the whole story especially on the newer BMW turbo motors as the gains in the mid-range are in the 50 wheel horsepower range. The torque curve is much fatter and the peak torque figure increases by 42 lb-ft at the wheels. People will obviously being comparing these flash figures to the BMS piggyback tune figures. As of today, piggyback tuning shows greater horsepower and torque gains. It will be interesting to see how these two approaches play out and the way they play out will likely be reminiscent of the N54 tuning scene in which each approach has its place with many people using both for the optimum setup. Regardless, the flash tuning era of the S55 inline-6 motor is officially underway.

The 'stone folks seem to think all is in very good shape, and my rudimentary understanding of oil reports shows everything in pretty tip top shape. But of course I value your thoughts. Fire away! They decided to give me a random home address :facepalm but oh well we can't have it all. Edit: I should add i'm posting this particular report as this is the longest OCI run i've ever done at 6K. No plans to extent it, if anything i'll return to my normal 4K changes.

    In an attempt to try and contribute as much as I do on N54tech, I wanted to give anyone installing a LPFP a word of caution. Specifically, you 535 guys who have to remove the plastic hose the cuts across the tank over to the drivers side from the LPFP outlet and gets replace with rubber fuel hose. MAKE SURE you use GATES submersible Fuel hose GATES part number is 27093 for 1ft of 5/16 inner diameter. You will need about 18" - 22". If you use any other fuel hose the outside layer will split exposing the braided core and the fuel will escape from the hose. This specific hose must be used.

    Hello, I am looking to sell my 335I. The mileage currently sits at 62XXX. The reason I post it as that is due to the fact that I may drive it every now and then. It is a 2009 Alpine White Coupe with an Automatic Transmission. It has the premium and sport packages with the extended beige interior. This vehicle has been modified and all stock parts will also be included. The vehicle was in a fender bender in 2011. I have paperwork documenting what was replaced by a certified Geico auto body. In short it was the headlight/foglight/fender/lower control arm. No structural damage. Modifications: JB4 G5 ISO Board Cobb V2 Handheld Evolution Racewerks Competition Intercooler with Carbon Fiber Shroud Evolution Racewerks Charepipe with Tial 40mm BOV VRSF Downpipes Muffler Delete Coolingmist 2.2gallon Methanol Kit with JB4 FSB for Safety--Dual Nozzle Setup Burger Motorsports DCI Apex Race Wheels ARC-8 17x9.5 square with 255/40/17 Front and 275/40/17 rear Bilstein PSS10 Coilovers Currently Have the rear seat pulled out and in storage as I never have anyone ride in the back. Stock Suspension/wheels/intake box/charge pipe/intercooler will be included with sale. Open to offers and trades. No low ballers please. I have not checked on the status of the title however as I stated previously minor cosmetic damage only.

    I know its been covered before, but I happened to have my tripod out and decided to snap some pictures and do a small write up. I didn't realize I had my macro lens on until after I was dirty, so enjoy the super close ups. So I started with a car that had the cabin filter, engine cover and cowl already off. Its only a few 8mm bolts to get to this point, no sweat. I may come back and add all the photos to get to this point but here's a picture of where we started: First step is to flip open the top of the coil to eject the harness plug. I grab both sides of the coil top as shown and pull up like flipping a lid. Do this for all 6: Next, in the hole of the lid, put a screwdriver through and then apply upward pressure to pull the coil out off the spark plug. In the picture i only have one hand on the screw driver, i used two but i couldn't take a picture showing it. Don't jerk the coil up and out, just slow pull up and they come right out: Once the coil pops up, then pull the coil out: Using a thin wall 14mm socket to take the spark plugs out: I used a wobble extension: Which allows the socket and extension to "wobble" or angle out of line from each other while still being engaged: A close up of the tip, similar to a CV joint - sort of anyway: Then, pretty important, blow each spark plug hole out. I had this on hand, its a tire inflate-tor that i removed the tire bit from, so its a flex hose blow gun: This actually turned out to be a really good picture of the spark plug. You can see how soft the edges are, and how big the gap is, showing just how used the plug actually is (63k miles). I wish i had a picture like this of the new one so you could see how squared off the prongs of the new plugs are. I couldn't see the detail in this until i uploaded it to my computer after the job was done. Lets just say replacing these plugs made a really noticeable improvement: So here we go with the new plugs and some anti-sieze: Anti-seize applied to the threads: Here we are dropping the spark plug into the cylinder head. Its important to thread this in by hand. I even prefer to use a straight extension if possible to have a better feel of the spark plug threading in. Don't get impatient here, if a plug isn't feeling right or threading right keep starting over until it threads in correctly: Here we are using a torque wrench set to 17 ft lbs, (approx 204 in pounds) tighten until it clicks: Never store a torque wrench pre-loaded, always unload it to 0 so it doesn't give inaccurate torque readings. Even better to have them calibrated every once in a while if you do really precision stuff: Once thats complete for all 6, drop the coils back in, align then correctly, and then push down on top of the coil until it bottoms out on the spark plug nipple: Then engage the harness plug and push the coil pack lid down until its in the closed / locked position: Willing to work with members in the Florida area. Enjoy the new plugs!

    This review will give some detail as to my experience with AA and the install of their gen 2 level 2 supercharger on my 2009 m3. They also installed WPC treated rod bearings but not much I can say about them except they was installed and my stock bearings looked near new even with 45k miles on the clock. First off forgive any misspellings or grammatical errors as I am just a simple oil field worker with hardly a high school education.:P I purchased a barely used gen2(upgraded from gen 1) level 3 kit some many months back and contacted Andrew at AA at that time to get a quote on install and downgrading to level 2. Before anyone asks this car is my daily and I refuse to run the meth kit the level 3 would require. I was quoted what I believed was a good price . Flash forward to a few weeks ago . I finally got some time off from work and decided to take my son to Disney World and have AA do the install of the kit/bearings while I was there. Drove from Houston Texas to Miami to drop the car off and meet with everyone at the shop. I gave them a one week deadline which they accepted. In the time that they had my car I had nothing but first class communication from Andrew. They found some problems with the kit that had been caused by a previous shop before I even got the kit. This reassured my decision to bring the car to the experts as I doubt any other shop would of been as thorough as the kits original designer. They even cut me one heck of a deal on a different manifold when the one I had was not repairable. A week later I drove back to AA to pick up the car. The car wasn't going to be ready till almost closing time but I had to show up early to drop off the rental car before I got charged another day anyways. So I hung out at the shop while my car was being buttoned up for the better part of half a day. I felt nothing but welcomed by every employee. Was given a nice tour of everything while I waited and just general good conversation with fellow car/BMW enthusiast . The mechanic stayed late making sure the car was perfect and the tune was nice and smooth. He had also stayed late the night before trying to make my one week deadline which I appreciated. Once the car was completed and turned back over to me I started on my drive back to Orlando for the night . The car was beyond smooth and power delivery shocked me and also a cop who decided to pull me over and write me a ticket. Which after explaining myself and showing him receipts he agreed to dismiss in court for me. The next day I left Orlando and headed home to Houston. Which ended up taking roughly 16 hours of straight driving . The car performed flawless the whole time. Even with the 4 or so hours of heavy downpour that I had to drive through. I liked the fact I no longer had to downshift and wind up the motor to pass slow moving traffic. The torque curve of the car is as it should of been from the factory now. After the 16 hour trip home I took the car straight to the drag strip to see what it could do. What I found out is the track had no prep to speak of and the PSS tires where not meant for drag racing. I only managed a 12.9 @ 123mph . this is with almost a 3sec 60 foot time and going all over the track till the top of 3rd. The car has so much more in it with proper tires . Anyways I just wanted to let everyone know my experience with Active Autowerkes and thank them for the amazing service. I wouldn't hesitate to use them ever again. Here is a short 3rd gear pull I took with my cell phone
