COBB Tuning is proud to announce the release of AccessTUNER Pro tuning software for AccessPORT equipped BMW N54-powered vehicles. The AccessPORT is the only hand-held OEM ECU flashing, managing and monitoring device available for N54 equipped BMWs, and when combined with AccessTUNER Pro software, the result is a groundbreaking, dyno-tunable engine management system with all of the sophistication and drivability inherent in the factory BMW ECU. A significant amount of time has been spent creating a simple, straight-forward interface that takes the mystery out of BMW's complex load-based tuning system. Intuitive changes produce predictable results and let you get down to the task of tuning. ...Published on 03-02-2012 12:48 AM
BimmerBoost member LostMarine met up at the ATCO dragstrip in New Jersey for some fun runs and a comparison with a manual M3. The blue E90 is a manual and the black E92 M3 is a DCT. Videos are from inside the E92 M3. Both cars have similar modifications with airfilters, Turner Motorsport test pipes, and mods to the OEM exhaust system. The DCT wins both races easily and the difference is quite large at over half a second and 3+ miles per hour. Videos and slips below. ...Published on 02-29-2012 10:11 PM
When we first heard about these upcoming triple turbo motors from BMW many of us scratched our heads wondering exactly how they would work. Rumors abounded. Two gas turbos and an electric turbo? A compound turbo setup? Well, this video should clear things up and explain how BMW is able to hit 381 horses and 546 pound-feet of torque in a production 3.0 liter diesel six cylinder. To have so much technology (like 3 variable turbine geometry turbos set to come on and supplement each other at different rpm ranges) not make it to the United States makes us want to cry. Watch the video and try not to shed any tears. ...Published on 02-28-2012 06:11 AM
Alex Zanardi. If that name does not ring a bell, please stop reading this and do some research about a legendary driver. Now, to be clear, this is a marketing piece. BMW did not accidentally have this happen while the X5 M was racing the M3 on the track. They chose a legendary Motorsport moment to mimic for a reason. That is fine, this still makes for a cool little video. We would like to see a real comparison of the two on Laguna Seca though just for fun. ...Published on 02-28-2012 03:47 AM
Here is the new M135i. The vehicle will be powered by the N55 single turbo six cylinder and have over 300 horsepower. How much over? Well, we expect it to be right around the same range with its crank rating as the BMW 1M. What it puts out to the wheels will be interesting to see. It will make its official debut in Geneva next month. Another interesting tidbit is that it will likely have an all wheel drive option when it goes on sale in Europe in July. Most likely not coming to the USA and we do not really mind. ...Published on 02-25-2012 09:15 AM
This is not a new comparison as it was done previously with the F10 528. Now time to see how far the N20 has raised the entry level (in the USA) 3 series game. Just by how much does it do that? Well, Insideline compared the 2010 3.0 liter N52 naturally aspirated six cylinder powered 328i to the new 2.0 liter N20 turbo four cylinder and the results are not all that surprising. The N20 328i ran the 1/4 mile in email@example.com. The N52 328i ran the 1/4 mile in firstname.lastname@example.org, fairly large difference for two motors rated at almost the same horsepower (240 for the N20 vs. 230 for the N52). ...Published on 02-24-2012 07:47 AM
The N54 had been stuck in a bit of a rut. There were upgraded turbo options out there but these were relegated to small twins often utilizing the stock housing. A large single turbo simply was necessary to take it to the next level. All the previous attempts at large single turbos had been abandoned. Vishnu showed it is in fact possible and at 22.5 PSI with 94 octane fuel and meth broke the 600 wheel horsepower barrier with a very impressive run hitting 626 although the graph was uncorrected. ...Published on 02-24-2012 03:52 AM
Why do people keep comparing the M5 to the GT-R? It is idiotic. We said as much when Autocar did it a few weeks ago. First, Mr. Harris starts with bagging on the E60 M5. The SMG III gearbox was really that confusing for him? The miles per gallon were an issue? It's a 5.0 liter V10 that revs to over 8000 RPM. Gallardo owners are not complaining about their MPG and neither was anyone who could afford an M5. The new F10 M5 is not going to be a Prius with its 17/22 MPG. Frankly, the fuel economy hit of the E60 M5 is worth it when you consider it does not need fake engine noise piped into the cabin. ...Published on 02-22-2012 07:02 AM
S85 V10 supercharger kits have lagged pretty far behind S65 development despite the V10 making its debut well before the V8. There are several reasons for this but the supercharged V10's are starting to come into their own. RPI refers to this setup as a Stage III and we are not exactly sure what that means. Higher boost most definitely but what else? Meth? Race gas tune? What fuel was used for the dyno runs and what boost? Why are these details missing? ...Published on 02-21-2012 09:35 PM
The P31 C63 AMG is a very strong car in stock form. While the regular C63 AMG and the DCT M3 is a drivers race the P31 is definitively stronger than the DCT M3 performing more like a standard C63 with a tune. So what happens when a tuned DCT M3 with bolt on's takes on a P31 C63? Well, check it out below with multiple runs from the cars. The M3 is claimed to have a tune, pulley, exhaust, and x-pipe and and the C63 AMG coupe is stated to be stock.

Congratulations to BMS (Burger Tuning / Motorsports) for raising the bar on stock turbo N54 performance yet again. The vehicle used was a E82 135i steptronic with a JB4, down pipes, dual cone intake, CM10 meth setup, FMIC, and race gas. The mile per hour (fastest) record in the 1/4 came on a run of email@example.com. The elapsed time (quickest) record came on a run of firstname.lastname@example.org. The trap speed dropped a bit with the better ET which is not surprising considering it came on a much better 60 foot. These records were set at Famoso Raceway which is a decent track but certainly not the best strip for setting records. ...Published on 02-18-2012 09:42 PM
We already knew the BMW N20 four cylinder was underrated from its 240 horsepower rating as we saw in a dynotest of the Z4 sDrive28i which put down 233 to the wheels. That dyno was done by Insideline who recently did a dyno of the new F30 328i and overlaid it with the Z4 dyno. As luck would have it, EAS also did a dynotest of the F30 328i so we have more than one graph to go on. For the record, Insideline was wrong about claiming they exclusively had the first 328i dyno. ...Published on 02-17-2012 12:21 AM
Things are progressing nicely on the M3 front with Gintani recently recording 828 horsepower at the crank in a manual E90 M3. The car has a low compression built motor (compression will not be revealed at this time) and hit 16.5 psi of boost from a Vortech YSI. The blower has more in it and could likely be overspun to the 22 psi range but for now 828 horsepower at 16.5 psi is very impressive and more than anyone has made up until today. Expect to see more out of these Stage III cars, like BimmerBoost's own project M3, in the next few weeks.

The new N20 motor certainly is opening eyes. The base 3 Series is basically on par with a US E36 power and acceleration wise. This was an 8-speed automatic version that weighed in at a hefty 3480 pounds. Definitely not light or comparable to an E36 M3 in that regard but the base 3 series has just gotten a lot faster than it used to be. The manual version is about 60 pounds lighter and we would expect to see high 13's in the 100 mph range out of the car in capable hands on the drag strip. ...Published on 02-14-2012 06:00 AM
BMW released two new videos showing off the F12 coupe and F13 cabriolet M6. The videos are not super exciting just short clips showing the cars moving. No acceleration comparison or thrashing around a road course. The videos would have been better without the music for us to be able to hear the engine opened up on the M6. What we really want to see is how the F12 M6 stacks up to the F10 M5. With the M6 being much lighter than the M5 this generation the fastest vehicle in the BMW lineup is poised to be the new M6. ...
