    Cold weather has officially set in up here in the Great White North, which is giving my car fits on cold starts with E85 blends. Following off of SAE research presented in 2009-01-0620, approximately 3x the amount of fuel injected during a cold start is necessary when using E85 versus gasoline to compensate for the vapor pressure differential in cold weather. Seeing as the Fuel Open Loop tables are not yet defined in ATR or any of the XDFs I've seen for TunerPro, it appears we're currently sitting at a dead end with respect to fixing this issue with a DME flash until Cobb or someone with major WinOLS skills can crack the table. I can't imagine I'm the only person driving a N54 in cold climates with an E85 blend so the question becomes, what other solutions have been brought to the table to fix this issue?

    Hey guys, Finally got a handle on the false knock issue and was able to strap the car down for a few higher boost dyno runs. We went with a "small" Precision 6266 G2 turbo for to keep low end response strong and I'm really happy we did. This thing drives great with instant torque almost anywhere. The little turbo puts out some decent power up top too. These runs are on 50% race gas and meth. Up next we'll be converting the car over to 100% E85 using our port injection setup and hopefully can squeeze a little more power out of it.

    So this morning I was on my way to class when this kid in a scion tc past by me. He apparently hit a patch of black ice and lost control of his vehicle. I saw the whole thing coming, but there was nothing I could do to save my car, he smacked into me and sent us both flying off into a ditch on the side of the highway. I will find out for sure if the car is totaled or not in the next few days, but after talking to my body shop (whom I have a great relationship with) they are confident it will be totaled. This really sucks because my car was finally coming together I just installed bc racing coilovers a few weeks ago along with all the other mods done to the car. Thankfully I was not at fault so hopefully everything will be covered by his insurance, but this still sucks:( I really don't know what car to get next... I loved my m3, but I don't want to get another one while I am still in college, this whole thing just sucks I worked hard to get this car and get it where is was and now all of it is gone.

    Hey guys, As a few of you know we've been fighting a false knock issue with our FFTEC built E92. Apparently the forged pistons or something else in the build has increased the engine harmonics leading to the DME detecting false knock. Typically this would be solved by adjusting the knock sensor sensitivity tables within the flash maps but these tables are not yet defined limiting us to external solutions. We found a short term solution in adding plastic spacers between the knock sensors and the block to "dampen" their feedback. Enough to block out false noise but allow legitimate knock through. This allowed us to 1/2 mile race the car, put down some nice dyno numbers, etc. After a lot of abuse we inspected the plugs which looked perfect. While this spacer method was effective it's crude and not adjustable. Going too thick triggers a "knock sensor too quiet" plausibility code during cruising. So I removed the spacers and started working on an electronic alternative. It turns out the solution is very simple. A 100k trim pot on each sensor signal wire (spots 19 & 20 on the large black subconnector). At 0% lots of false knock. And at 65% no false knock. Use one pot on each bank so they can be independently adjusted. Going too high will also filter out real knock & trigger a knock sensor too quiet code so you'll have to use judgement and trail & error if you choose to play around with this. In a related note I've been starting to wonder if ijeos automatic timing flatline is really just false knock. We'll be doing some additional testing on that front soon and I'll keep everyone updated as to the results.

    Hey guys, It's been a while since I've dug into this topic and with the N54 platform advancing so much in the recent months, I am completely overwhelmed with info. So there was a conversation a while back about the limits of the stock TMAP sensor being around 19-20 psi... Someone (I think Terry) figured out that the N20 TMAP sensor can be installed with a small connector adapter allowing for correct boost readout up to 23psi or so... Now, I know JB4 can deal with this much boost because it intercepts the sensor signals and then decided to tell different things to the ECU. I am wondering one can make a 21 psi map for Cobb via ATR and use the N20 TMAP sensor reliably. Of course, this assumes upgraded turbos and fueling. Thanks in advance.

    Definitely nice to see more numbers for stock internal turbocharged E46 M3 S54's that are tuned on the factory computer. Maximum PSI previously showed horsepower in the high 690 wheel range with torque in the low 500 lb-ft range for the Stage II kit. This particular car is producing a bit less horsepower but a bit more torque with 676 horsepower and 532 lb-ft of torque at the wheels. The supporting mods between the cars are likely different and possibly the turbocharger as well although that is something Maximum PSI would have to clarify. The modifications to the SMG E46 M3 are: - Maximum PSI Stage 2 turbo kit - Maximum PSI 3 inch exhaust system - Stock DME tuning - MS109 Fuel For those wondering, Stage 3 ups the power figures to over 800 wheel horsepower but that requires a built motor and the Stage 3 is still being worked on as we understand it.

    In preparation for the Single Turbo Kit, I am reviewing the options of going for level 10 6AT build from scratch or a DCT Swap. The DCT swap is ~4k dearer than a level 10 6AT build but the DCT swap will offer faster shift speed and for some odd reason, I have more faith in the upgraded clutch pack from Dodson than the level 10 option. No one have tried it before apart from Gintani's attempt. No update from them as yet. Anyway, I hope you guys could help with the queries below: Level 10 6AT Build - 800whp and 700wtq 1. I am based in Australia so it will be cheaper for me to get Level 10 to build a 6AT from another core instead of mine. Will there be any compatibility issue in terms of software or hardware? Based on the part number from RealOEM, the hardware appears to be the same. I am just worried the TCU in America will be different from the ones in Australia. 2. Have you replace your 6AT with a 6AT from a wreck? Did it work and what's involved besides the manual labour to replace the 6AT? I presumed programming is required to ensure your DME will work with the new 6AT TCU. Will Autologic be sufficient or do I need to go back to the dealer for programming? DCT Swap with Dodson Clutch - 800wtq 1. Anyone with insider news from Gintani on the Dodson upgraded clutch pack? Is it working or not? PM me if you will like to keep it private. 2. For this job, I am thinking of buying a whole 335iS wreck from America or the n54 DCT wreck from the UK. I am looking for someone who's willing to buy the wreck on my behalf, remove and package the parts and organise shipping to Australia. The buyer can use or sell the parts from the wreck and I will have NO entitlement on the wreck or profit after I get all the parts required for the DCT swap. I am willing to reimburse man-hours involved in buying the wreck, organising shipping, the labour involved in removing and packaging the parts for delivery to me. Please PM me if you are interested in the above. Cheers, Alex

    I attended my second roll race this year and had a blast. The slipstream roll race events are a ton of fun and if anyone is on the fence about attending one, I can tell you, when it comes to the car scene, there isn't anything else on the east coast i'd rather do. Car shows, caravans, meets, don't compare, these events are fun as hell and the people there are even more fun. You have cars with 2000-400 hp, all makes and models and people that just want to race and see how their cars compare. I really wish more BMW's would attend so hopefully as people realize there are events like these on the east coast, I'll have some more people to run! My first event I went to was this July and I was able to race a ESS 650+ (ACM r package ) Supercharged M3. He was on race fuel, weight reduction, etc. and I was full weight and 93 pump. I lost by 2 1/2 car lengths and was pretty happy with that result:) I really don't care if I win or lose, I like to see how my car stacks up. I was hoping to run a supercharged M that was close to my kit (E600) but never had the chance to. Fortunately, my second event I attended this November had some more cars in my HP class and I was able to get some vid of the action. A litte description of the vid: My first race on the vid is against a 700 hp+ supra, that smoked me, pretty mean sounding car! My second race was against a 570hp Evo X that actually got a slight jump on me at the cones but I was able to reel him in and get him at the end. My last race was against a buddy of mine with a ESS 595 e92 M3. We were both on race gas, both full weight, both DCT. It was fun to run a car more in my HP range. We ran a total of two times, I got him both times, the first run wasn't on this video but I know he has a vid, it was closer than what you'll see here but my car was still adapting to the race gas. We grabbed lunch, I was confident my car was fully adapted and we ran again. That is the run you see here, one view from the sidelines, one view from my go pro on my trunk. As I said...I really hope more BMW's come out to these events, you get as many runs as you can take and its a ton of fun. Great place to meet fellow enthusiasts!:handgestures-thumb:

    Car is 09 335i N54 auto now about 111k miles. Walnut blast done about 35k miles ago New OEM type Bosch ZGR6STE2 about 5k miles ago New coils about 1k miles ago New injectors 1k miles ago New vacuum tubing about 5k miles ago Car has BB / Wedge flash, but saw no difference in stumble with stock (maybe slightly less). Tried swapping Diverter vales before replacing injectors to new ones and saw no change, car still stumble at low RPM, no issues on idle or at higher RPM. Stutter only when accelerating when cruising and hitting it, more so when there is no gear change (light acceleration). If I go WOT, at times it starts running like crap and starts misfiring along with check engine light. Restarting the car fixes misfiring. Sometimes codes show misfire cylinder 5, 1 and multiple misfires. At this point, I might try swapping DVs again, and next maybe replace charge pipe? It sounds very familiar as on this thread in E90post: http://www.e90post.com/forums/showthread.php?t=337084 Particularly this post: "Mine is interesting....it is not throwing any codes. From a stop, WOT no problem all the way through. However, when the car is cruising and you do the WOT it shudders/hesitates/hicups, feels thud sounds. But if you just accelerate slowly it's fine, it's when you accelerate fast it shudders again. Any ideas guys.....maybe i just need to live with this....." Any ideas / suggestions welcome.

    Very interesting video here showing a pair of 991 Turbo S Porsches against a Lamborghini Aventador on the highway. The Aventador is a very fast car in stock form but has been a target for tuned German cars and obviously a vehicle like the Lamborghini makes for quite the measuring stick. Tuned M157 63 AMG's AMG's have been able to pull the Aventador on the highway. Now we have seen the Aventador run the new Porsche 991 Turbo S but it was not a highway matchup rather a standing kilometer drag race. The Turbo S by virtue of its launch wins the drag race but the Aventador has the slightly higher trap speeds at the 1/4 mile and kilometer marks. On paper, that means in a highway showdown the Aventador should beat the 991 Turbo S from a roll. In the video below you will see that is how it plays out. The white Porsche 991 Turbo S has a full Cargraphic exhaust system and the red Turbo S has a Cargraphic X-pipe. The Aventador also has an aftermarket exhaust system. The Aventador pulls up top as it should although the turbo torque of the 991 Turbo S gives it a slight edge down low also as it should. This race plays out as expected on paper and the Aventador gets a chance to show its top end strength.

    Hello all you N55 faithful! We are excited to announce our N55 Stage 2 JB turbocharger is finished, and was sent off to its tester today to be ran through its paces. We are very excited for thise new Stage 2 offering for the N55, this brings the performance of a VTT Stage 2 DBB with a price that is much easier to swallow. For this upgrade we were able to keep the stock V-band flange, and V-band clamp! We machined around the existing flange and found a very efficient way to bolt on a much bigger and robust CHRA over stock, this JB option also uses all the same installation hardware as our DBB kits, so you get the same fit and finish the N55 DBB is known for but in a JB package. Some specs on the VTT N55 Stage 2 JB The wheels we have chosen are as follows Compressor wheel: Billet 6x6 Blade design 60.2MM inducer 78MM Exducer This makes the Jb turbo 2mm larger on the exducer than our DBB Stage 2 for slightly more flow. Turbine wheel: 11 blade design clipped to 12 degrees 61MM inducer 54MM Exducer This is 1mm bigger on the inducer, but 1mm smaller on the exducer for very similar flow and performance to our DBB Stage 2. The JB Stage 2 has the option for the upgraded Forge/VTT Billet DV, as well as our soon to be announced N55 waste gate upgrade. In the pictures below the JB sent out has the upgraded waste gate, and Billet DV options. We have no exact date for when these will be released, but with a successful testing program, we should have at least 2 units in stock ready to ship by the middle of Dec. The price for the VTT N55 Stage 2 JB unit be $2599 before options. We are confident this new offering will dominate the N55 landscape just as our DBB Stage 2 has. As always thank you for the continued support!

    Hey guys, So my Openflash Tablet won't connect to my car. Every time it starts writing and then says "failure to communicate with DME". I recently blew out a few transistors in my DME a couple weeks ago and replaced those but this thing will not connect at all. It says the same thing when I try to read codes also. Any ideas?? Thanks

    BMW and AMG were right next to each other at the 2014 Los Angeles International Auto Show. Even though the proximity was close the energy between the two was completely different. While AMG had this buzz in the air of excitement with new products BMW could not have been more businesslike. You notice this when the first thing that happens when you walk over to BMW is their security stops you to check your credentials before you are allowed near their precious i8. Relax guys, I don't even want one. Plus I've seen it before the previous year. And the year before that. In the exact same spot next to the exact same i3 with the exact same info... So with three years in a row of the same i8 and i3 and BMW pushing its 'i' brand into the spotlight over everything else it is starting to get a bit boring. Was there anything exciting? Well, not really. Since BMW debuted the 2016 F85 X5M and F86 X6M almost a month before the show there was not really anything new to learn about not to mention the M SUV's are not all that different from the vehicles they are replacing both inside and out. Compared to Mercedes-AMG the display at BMW was boring. While the AMG reps were standing proud on an elevated display singing the praises of their new AMG GT sports car and C63 AMG you did not see any excitement from BMW or their reps. Not a single rep approached me to discuss anything and that may be for the best as what are they supposed to say when I ask where their AMG GT or Black Series answer is? While AMG was debating me, popping hoods, interacting, and engaging with the enthusiasts BMW was making sure no 'undesirables' were getting too close to the i8. Say what you will but you can feel how each company is changing direction not only in their product lines but how they are displayed. Mercedes-AMG proudly showed off having the most powerful four-cylinder motor in the world with their M133 engine display stand and BMW showed off their carbon spoilers from the M Performance catalog on an orange M4. In addition to their 'future is here' display that apparently is the future of the BMW car show circuit for the... foreseeable future. Your current future lacks excitement BMW. It is what it is.

    Well the good news keeps coming for the N55 crowd as we finished another product in our N55 line up the same time as our Stage 2 JB...:) We are extremely happy to announce our BRAND NEW VTT N55 STAGE 1 turbos. When we say brand new, what we mean is these turbos are not built from cores, we went through the process of having N55 compressor housings, Bearing housings, Turbine Wheels, compressor wheels, and internal parts, cast and manufactured, so we can now offer BRAND NEW N55 Stage 1 turbochargers with NO CORE CHARGE! These turbos are exactly the same specs as our previous Reman N55 stage ones which showed a consistent 40-70WHP increase in power, except of course built from brand new parts. What does this mean for our N55 stage 1 reman program? We will still be offering those units but at a new LOWER price and even cheaper core program...:naughty: The prices for our VTT Stage 1 turbos will now be as follows. VTT N55 Stage 1 turbo brand new no core: $1299 (IF you want to send us your core, we will give you back an additional $200 once we receive it! Bringing the price down to $1099 for a brand new turbo!) VTT N55 Stage 1 turbo Remanufactured: $799 with a $200 core That's right $799 for an N55 Stage 1 turbo, with only a $200 core! This now brings the N55 stage 1 upgrade into anyones price range. Having brand new units also means one more thing as well. NO WAITING! Since we do not have to send anything out to be machined or wait on cores, we can keep many units in stock and can ship the SAME DAY as they are ordered. We are scheduled to receive our first shipment of 15 Brand new N55 Stage 1's the first week in December, (these will be included in our Black Friday promotion for even more savings! :scared-eek::dance:) This is something that will surely change the N55 world as now turbo upgrades are truly affordable and available! We look forward to getting these into your hands, of course if you have any questions email Sales@vargasturbo.com for more info. Thanks! VTT

    Searched but couldn't find anything related to this. Was doing the install and when I put the lock ring back on and tightened it down, a small spurt of fuel came out of the large vent tube connector. Is this a sign that I did something wrong, or is it from the pressure imbalance between the tank and outside? Don't want to start my car in case I did the install wrong.
