    The Pure Turbos Stage 2 N54 upgrade sure looks like the real deal. The turbo upgrade is not 'officially' out yet but expect it next month. For now what we have seen is numbers in the 6XX wheel range and here is a preview of the real world capability. BimmerBoost member @pr3ci5n335i in the video below runs his E90 automatic 335i against a 2014 Nissan GTR on E85 with full bolt ons. The 335i is at roughly 25 psi of boost and also has full bolt ons in addition to the Pure Turbos Stage 2 N54 turbo upgrade. He also has the TFT inlets and his fuel in the video is an E50 blend with meth injection. The 335i takes the hit here but steadily pulls the GTR until it shuts down. Definitely an impressive result considering what bolt on GTR's on E85 are capable of. 2010 E90 M 335i: Alpina AT, FBO (VRSF 5" Stepped FMIC, Catless with BMW PE, TFT upper and lower chargepipes, HKS BOV, BMS 2 gallon Meth kit, Stage 1 Walbro 255 inline LPFP, BMS low temperature thermostat bypass), JB4 map 3 80add, BMS E85 Flash using MHD, Pure S2 turbos, APEX Arc-8, no rear seats

    A guy who's running one of my E50 maps just did work his first time ever at the track, guess he got misfires and only ran two runs. I think he could get down to a 1.5 60 footer and maybe 11.4 territory with more than 2 runs. That's what 532 wheel torque & x-drive can do on all season tires... 1.6' 60 footer :naughty:

    Hey guys, We've started tuning the E92 with modified twins and came across an interesting issue. A fairly large and unexplained fuel trim bank to bank variance. Note bank1 is shown under trims and bank2 trims are shown under average advance. They will get a full time home soon. After pulling our hair out for a day or two we decided it might be a partially clogged fuel injector on the port injection rail allowing one bank to be thrown off. Tore it apart to swap them and found the issue... Torn gaskets on the back 2 cylinders. Basically a boost leak on two of the cylinders. We've had the rail on and off several times and this must have happened without us knowing at some point. With new gaskets in bank to bank trims went right back to normal. Right now the JB4 does not have a bank to bank safety built in but we're going to add one shortly. If banks deviate by more than 10% at full throttle we'll have it trigger a map 4 safety switch. Still a handful of issues to resolve with the car including a mystery misfire. At least it's on the right track now.

    That is the current rumor although it is based somewhat in reality. The new G11 7-Series is rumored to get this new 3.0 liter inline-6 diesel with four turbochargers. This would be utilized in a M750d model that would have xDrive all wheel drive and would not launch until well into 2016. That is of course providing the information is accurate. BMW does produce a tri-turbo 3.0 liter inline-6 in the 550d / 50d models. The triple turbocharged motor produces 381 horsepower and 546 lb-ft of torque. BMW is expected to take things beyond 400 horsepower and 600 lb-ft of torque with this new quad turbocharged motor. It is unknown if this motor will use conventional turbochargers or if there will be some sort compressor spun with electricity to supplement the exhaust driven turbos. It is too early to tell at this time but even if BMW does produce this the chances of it coming to the USA are slim to none. Source

    Finally getting with the times and welded some inlets for my car, figured I share :awesome: Will probably wrap them in gold foil or something eventually. Specs : 2" dia 16g SS304, K&N RU-5111 filters Scotchbrited on left, welded but before prep on right. Weld detail : Installed : Couple notes for install on a 1M or any car with the supplemental radiator, the lines get in the way if you relocate the coolant tank like I have it. Modding the coolant level sensor mount tabs so it can go in with the plug pointing 180* the other way will let the tank tuck far enough over against the fender liner.

    I was lucky enough to have my "Vent Hose" crack while stopped at my local gas station. Was all good until I started the car to drive off, and them it started spraying coolant everywhere. So not wanting to put (not so cheap) plastic parts back in there, I found a 2ft section of 5/16 stainless and proceed to cut the pipes down until I had something to attach to the stainless. Clamped the first side on , great, go to clamp the side nearest the top hose and snap !! the port on the top hose snapped off. Next day I went to the BMWMiniParts store in Cincinnati and bought a gallon of coolant and a new top hose. I still am using my repaired vent hose and all looks great with no leaks. Also, while I was doing this, I replaced all 6 injectors and cleaned/reseated the coils. Coded the injectors to the car and now it drives like it should have. I was told my my local dealer I would have to pay $3800 as the recall Sib 13-14-10 did not apply to my car due to milage. Many thanks go out to AlpineLA for getting me all 6 injectors for $102. I saved $3698 that I now want to spend on tuning. (i already have a Procede Rev3 V5 ) and want DCI, FMIC and a few other upgrades as I guess, BMW will refuse any warranty work on this car anyway. Moral of this story, BMW designed parts that I believe have definitive lives, so that you have to replace them when they fail.

    Hello guys, I recently installed a jb4 on my 2007 bmw 335i. I took it for a test drive and after about of mile of successfully driving the newly tuned car, I suddenly lost engine power and the car went into limp mode. I first thought it was the valve cover gasket, I went ahead and also changed my spark plugs with the valve cover gasket replacement. After these, the car still did not run right. I had a friend with a code reader, and I had a couple of misfires (3 i think), as well as a DME Internal Failure code, along with something about misfiring with low fuel level. I removed the jb4 and the codes and issues still remained. Does anyone have any idea what could be wrong? Here is my code readings from jb4: And heres what it sounds like when you idle/rev it:

    jyamona started a thread Raised Idle = 2ADF Code in N54
    Hey guys, I have been running the 960rpm idle across all tables for awhile now, and stumbled across a code (didn't throw a CEL), when checking some OBD readiness stuff. The code is 2ADF: idle running control, speed. It's not a big deal, and it can be disabled, but I'm curious if it is happening to anyone else now. Can those of you who raised your idle, check if you have this code? There are probably some single cell idle setpoints for various things that need to be defined as well to truly fix this, just debating if it is worth the effort vs. disabling the code. Thanks!

    Fishayyy started a thread Rear Main Seal/Twin Disc in N54
    So Spec should be sending me my replacement rigid full-face discs for my Motiv clutch and I wanted to get some opinions on a few different things. Last time I swapped my clutch I had a very minor leak on my rear main seal so I wanted to replace it this time around, however I'm not sure if I need everything to be OEM or not. I've seen a mix of people recommend using the OEM seal and others saying that they got one from O'reilly's or one from a 2006 Porsche that seemed stronger. I've also seen a lot of people say that you need the OEM Locktite and others that say you don't need it. So I'm a little lost as to what I should try and what install procedures should be followed. Thanks in advance for the help!

    Hi all, Any help would be greatly appreciated. I've been searching like crazy to try solve this issue. Every time I start the latest (v1.2) software it stops working. I've tried FIVE different computers. I even went down to the store today and bought the cheapest, slowest ASUS computer they had. It is an intel atom, not an AMD, but it seems that works for most. Windows 8 unfortunately. The bb_flash log shows this... 5.4219 FTD2XX_NET.FTDI Attempting to load FTD2XX.DLL from: C:\Users\Kevin\AppData\Local\Apps\2.0\NTWLKBPA.2QZ \BHPHM8ND.G4J\bimm..tion_6163feca8559b1f9_0001.000 0_59ea2ce698cae162 5.4436 FTD2XX_NET.FTDI Failed to load FTD2XX.DLL.

No luck. - JB4 is in map 0 - Order was plug into car, plug into computer, key in, push start without starting (all the lights are on), launch BB Could it be the cable? doubtful give the BT sw works. Could it be my DME? Or am I just screwed until I find just the right "old computer"? Help, please!

    Jonny Lieberman works for MotorTrend and you probably have seen him in the Head 2 Head episodes. BimmerBoost has nothing against him although we wonder how someone gets a job with MotorTrend when they make basic mistakes. Liberman's job is to know about the cars he is talking about. Which is why BimmerBoost made it a point to explain that in the latest Head 2 Head where he states the ATS-V is more powerful than the F80 M3 because the M3 has 'only' 425 horsepower Liberman and MotorTrend are wrong. Very wrong. Absurdly wrong. Embarrassingly wrong. The F80 M3 and the F82 M4 are severely underrated. The car makes much more than its 425 horsepower crank rating. Frankly, it is closer to a wheel horsepower rating than a crank horsepower rating. One should assume this simply by juxtaposing the acceleration figures of the F80 M3 and E90 M3. The difference is not 11 horses. MotorTrend's own test figures prove that. The F80 M3 is insanely underrated. Now we have dyno results showing 427 horsepower to the wheels for the F80 M3. We have stock 1/4 mile times showing 11.9 @ 119. Liberman claims to be aware of the M3 being underrated but when asked for proof provided nothing to support this. Additionally, he does not mention the M3 is underrated in the Head 2 Head video. He states the ATS-V is more powerful. He also on Twitter states his support for this as the ATS-V being quicker despite being heavier. While the ATS-V does indeed get a 12.1 second elapsed time as tested by MotorTrend the F80 M3 gets a 12.3 @ 118.1 miles per hour. The ATS-V hits 12.1 at a slower 116.2. The only thing Liberman gets right here is that the ATS-V is quicker but it is not faster. Trap speed is primarily a product of power. MotorTrend's own numbers and Liberman's own statement support BimmerBoost. Point easily proven without even having to show the dyno numbers. Not to mention, the guy should probably know that a RWD car with a ton of torque that traps higher will improve its elapsed time with better traction off the line. That means the M3 with drag radials can be a hell of a lot quicker. Perhaps MotorTrend just doesn't know how to launch as well. Liberman goes on to state I need to check my facts. The same man who called the new S65 AMG V12 an M275 model despite it being the updated M279 V12 variant from AMG. He conveniently ignores this point. One who does not get their own facts correct should not be telling others to check theirs. Liberman and MotorTrend need to check their own facts. Rather than lobbing insults for getting called on their mistakes, they should correct them. There is no shame in being wrong. There is a bit of shame in a 'kid' knowing the facts better than the professional though, right? Liberman, if you ever want to engage in a debate with me feel free. Based on what I have seen so far it will be one-sided. Whenever you want to, I'm right here. MotorTrend, when you are ready to hire someone who checks their facts, let me know.

    Hi everyone, wanted to see if we could get some constructive conversation going about the rev limiter on our car... I'm not sure about all of you, but I HATE soft rev limiters on any performance application. Whether you drag race, autocross, drift or even just want to do some donuts once in a while, a soft limiter that gently hits redline and then closes the throttle plate can be a huge annoyance. You lose your boost pressure and the car bogs down -- in a turn, drift or gunning it to the next cone, or away from it, this can unsettle the car, slow you down and cost you time, not to mention, it sounds terrible. I've looked around a bit to see what options we have. A friend of mine had a 135i with the now totally obsolete Procede, and he was able to set a hard limiter on his car, which tells me this can in-fact be done with tuning. Again, not trying to start a conversation about moving to Procede or anything stupid like that, this is merely an example to show it's possible and it's been done. A thread, with logs, can be seen here on this topic: There is the BMS add-on to JB4 G5 ISO (manual only) N54 cars to activate 2-step and NLS, and that's all great, however, it's only activated when the clutch is disengaged and you're at WOT. What I'm after, though, is a hard limiter in-gear and on throttle -- more brap, brap, brap than vroom-meh-vroom. I just flashed my car with the BimmerBoost/BMS backend flash, and I believe the soft limiter could be changed and manipulated in the backend, through TunerPro or the like? Thoughts? Meanwhile, here's a boring video where you clearly hear the soft limiter at the top of 1st gear in my car, along with a great example of a hard limiter that came on my buddies e36... drool Cheers, Alex

    I am getting ready to switch from stock turbos to Pure N54 turbos and I am really unsure about what I should do with my tune. I have been very happy with Cobb and custom tunes from Wedge. However, I continue to read on this form and others that I will need more boost control with hybrids, which JB4 is supposed to do better than flash alone. I have a Z4 DCT so I need tuning that won't allow my clutch to slip. I have never tuned this car myself and I don't plan on starting. I want to get my new turbo and inlet setup in a manner that requires very little ongoing adjustments with my tune. I will either use E50 or 93. So, give me some advantages of JB4 with Backend Flash or Flash alone.

    I can't say enough about how happy I am with the tune on this car. I worked with Dimitri in April and May on an E50 tune and I haven't touched it since. I am also using the stock LPFP and no PI. Both of these runs were before they started to put anything on the track and I was able to hook pretty good. It was about 87 degrees when I made both of these passes. They started to put water on the track for the guys with drag slicks but it killed my ability to hook this car up. My Z4 is DCT but I don't like to use launch control. I do the alternate method of pushing the accelerator quickly and pushing down the kick down. This will raise the rpm's and you have to let your foot off of the accelerator when the rpm's come back down and at the same time as the light goes green. It is difficult to do but if you can time it right then you can get great times with the DCT. I feel certain that this car can run in the 11's on stock turbos and stock inlets. However, I probably won't be able to try again because I am going to install Pure Turbos and VTT inlets in the next month or so.

    Make sure that what you're converting is in ft lbs and deg F, not the opposite way (newton meters and deg C). I've been converting my original Cobb tune over to TunerPro to flash with MHD and had to modify some X and Y axis to match, and then convert the n-m to ft lbs as well as C to F. Took me a week of hair pulling, beer drinking, multiple logs, multiple engine codes, and lost sleep over something so simple.

    Hey guys, I hope this hasn't been covered but I'm a member of all the major forums and haven't seen this exact topic. Is there a "beginner's tuning guide" for the n54 anywhere? I would like to use mhd to flash tunes I've personally tweaked. From what I've gathered I would use Tunerpro on my PC to edit, and MHD to read and write from my phone or tablet. Correct? I understand the dangers of running a bad tune and I know it's easy to run OTS tunes, but I would love to learn this skill. Thank you for answers in advance.

    We have seen a drag race between these two cars before with the Aventador coming out on top. The Aventador should come out on top although the two cars are closely matched. The Aventador is more powerful thanks to its larger 6.5 liter V12 but it is also heavier. It also has an ISR (Independent Shift Rod) transmission instead of a DCT (dual clutch) transmission. It looks like the Huracan's shift speed pays dividends in this race. The difference between the two is almost 100 horsepower and 100 lb-ft of torque. This certainly means the previous result we saw makes sense as it is close but the Aventador edges up top. In this race the Aventador has the lower trap speed which leaves us scratching our heads. Both cars are said to have an exhaust but is there more going on here? Another standing kilometer run between these two shows the Aventador as the faster of the two with the higher trap speeds although it does have an aftermarket exhaust. Keep in mind we have seen these cars on the highway as well with the Aventador showing its power advantage. This is the only result we have seen thus far with a Huracan coming out on top and trapping higher than its big brother. They are close, no doubt, but we think modifications play a role in the outcome here based on precedent.

    This MotorTrend Head 2 Head episode is not exactly their best. Why? Well, because it is rehashing a MotorTrend comparison we already saw a month ago. Except they are leaving the F80 M3 out of it this time. Why? Because their reasoning is the Mercedes and Cadillac need to climb the ranks first before getting a shot at the title. Trying to apply a boxing analogy here is so idiotic it is hard to even articulate it. If Mercedes and Cadillac have not yet proven enough in their history to have their cars compared to the M3 something is seriously wrong with the people at MotorTrend. Furthermore, these are cars, not boxers. There is not some long string of challengers the ATS-V must topple for years and years before getting a shot at the M3. It is just moronic, compare the three cars. Everyone already has compared the cars including MotorTrend themselves so why do they do not throw in the M3 they already have sitting there that already was used for this purpose as it is the same damn press car they already tested? The numbers are the exact same from the comparison from last month making us think all Head 2 Head does is take the test figures the other editors get and simply adds video to them. Since we already know the results from the magazine the C63 is the fastest while the ATS-V is the best handling and the F80 M3 is the lightest. MotorTrend picks the C63 with the ATS-V coming in second and the F80 M3 comes in last place. Now to continue on how this Head 2 Head video just stinks as it adds nothing new the tester states the ATS-V is more powerful than the F80 M3. We are sick of hearing this. The M3 does not have 425 horsepower. What the hell does it take to get these journalists to do some basic research to figure this out? Just because the ATS-V is rated at 464 horsepower on paper does not make it more powerful. MotorTrend's own test results show the M3 trapping higher. The F80 M3 S55 engine is underrated. Google it, look at a dyno, do something more sophisticated than spewing the same manufacturer specs anyone can parrot back. We learn nothing new. The ATS-V drives great but has garbage interior refinement. The Mercedes-AMG is more well rounded. It is everything we already knew and MotorTrend already told us. He complains about the ATS-V transmission but somehow forgets a manual is available for it. At least complain correctly. Is there anything of merit? Well, seeing the cars on the track lapping to put them context of the track numbers we already got is nice to see. Randy Pobst is the resident MotorTrend hotshoe and he adds his impressions. He comes away impressed with the ATS-V handling and feels the C63 is more of a brute but its braking is more confidence inspiring. Here are the laptimes: Lap times: Caddy ATS-V 1:31.43 C63 1:31.52 BMW M3 1:32.51 We included the M3 because as stated we already had the M3 data. So why do they omit it when they have it as well? Would it have ruined their track overlay by including a third car when they already did include a third car originally? Ultimately they say the ATS-V is the car for performance enthusiasts as it outperforms the C63 AMG S but the thing is, it doesn't. Sure, it has the quicker laptime but they forget to mention the C63 has the faster trap speed. Enthusiasts interested in raw grunt will prefer the faster C63 with the larger V8 motor. This Head 2 Head could be a hell of a lot better. You do not learn anything new but you get video to go with the text and numbers a month later and MotorTrend generates clicks reusing content. That's automotive journalism today for you.
