A
Message from Alan@ModBargains, Sales:
"The
first thing I would like to say about the COBB AccessPort is that I have it installed
on my own BMW E92 335i and I absolutely love it! First off, the installation is
a breeze. It takes only minutes and is just about as easy as it gets. The COBB
AccessPort comes with truly great technology that is easy to update and easy to
use. The best analogy I can use is that COBB has achieved what Apple achieved
when it released the first iPhone. This product is setting a new standard in the
BMW market in terms of ease of use with great performing features."
"The
performance is incredible! My car has never felt faster, and I have had other
types of tuning software on my car before. Not only is it quick & fast, but more
importantly the power is delivered SMOOTHLY throughout the entire powerband.
There is no herky-jerky feel to this product. The car pulls hard with no hiccups
through the entire RPM range. If you’re looking for a great way to increase the
performance on your car, I highly recommend the COBB AccessPort." |
Unleash hidden power within your
BMW 135i, 1M, 335i/xi, 535i/xi, or Z4 with the Cobb AccessPORT ECU Flash Tuner.
The Cobb AccessPORT ECU Flash simply replaces conservative factory settings with
more aggressive calibrations that result in impressive gains in torque and
horsepower while still maintaining a high degree of safety for your N54
engine. The tuning is extremely flexible and allows you to choose on the fly one
of the performance maps that are loaded onto the AccessPORT. If you are looking
to extract the most out of your N54 the AccessPORT even allows for custom
mapping. Typical performance gains from the Cobb AccessPORT are
increases of 30% peak horsepower and an amazing 38% increase in peak torque.
This tune is an ECU flash, not a piggy-back tuner, there will be no added
devices to your vehicle's ECU.

Important Note -
Occasionally an "Unrecognized ROM" will be discovered during the AccessPORT
Install process. If an "Unrecognized ROM" is encountered, the user will be
prompted to dump the ROM using the onboard Dump ROM tool built into the
AccessPORT. Simple step-by-step instructions for dumping an "Unrecognized ROM"
can be found
here. The ROM is then emailed to COBB Tuning and
incorporated into the firmware. COBB Tuning will make every effort to
incorporate these new ROMs as quickly as possible. This process can take up to
five business days. See the "Supported ROMs" Tab above for a complete list on
what ROMs are currently supported.

Customer Reviews
Mine is a stock 2008 e90 335i. I previously
had a JB+ installed and I thought I was happy with it, until I came
across the COBB Accessport and I was immediately drawn in to the idea of
not having to mess around with the electronics of the car and having to
uninstall hardware every time I went to the dealer. Another bonus for me
was the fact that the unit comes with free future upgrades of maps,
because I did not want to buy a piece of hardware and it becoming
obsolete a few months down the road through the release of a newer,
better one. So I took the bath and bought it. Thanks again to Alan at
ModBargains.com for the great assistance and hooking me up with a great
deal on this unit.
So I loaded the map for 93 octane and went for a spin... all I can say
is holy crap! This car is a beast now! I cannot believe that this kind
of power has been "reserved" in this car and the COBB was able to
unleash it. Power delivery is smooth, and I had no trouble driving in
wife-in-car mode, but push that accelerator down just a tad more and
watch out! I have trouble keeping the rubber on the road now so I guess
I will be looking for some new tires pretty soon, as the stock run-flats
are clearly not up to the task any more.
Great job COBB and Alan at Modbargains.com. Happy customer here!
Oh, and anyone coming from a JB+ or stock car and not being totally
blown away by this tune needs to get their butt-dyno examined.

Just wanted to say thank you for your
help with my Cobb AcessPORT. Alan took time to answer all my questions
and was helpful. I appreciate what you did for me!

BMWsky@E90post.com
Just ordered my Cobb AccessPORT! Alan was
very patient as I had many questions about the technology compared to
everything else out there. He was objective in his explanation, and
answered any questions I had. Great price on a great product I'm sure. I
just can't wait to get in and put it to work! Will definitely do
business with them again.

chocobo15@E90post.com I
LOVE my Cobb. The car is now amazingly quick, and I've seen an
improvement in MPG. Thanks again, you've been a pleasure to deal with.
- Alex N. "I also bought the
AccessPORT from Alan at ModBargains, he definitely hooks it up after
looking around it was the best deal! I am completely satisfied with the
AccessPORT the gains are amazing I highly recommend."
-
McFly912@e90post.com I
received my Cobb tuner unit and promptly installed in onto my 335i
immediately after taking the box from the hand of the mailman. Wow -
what an amazing difference this unit makes! I am absolutely floored by
the amount of extra HP and torque lying dormant inside my stock engine
all this time. I love that it’s very simple to install, there are no
hardware changes to mess with, and everything easily reverts back to
stock configuration in minutes. I mounted the handheld unit on my dash
so I can use the neat live data monitoring features. Absolutely the best
money I’ve spent yet on my car. Thanks for your help!

What models are currently supported by the AccessPORT?
The AccessPORT is available for N54 2008-2010 BMW 135i, 335i and 535i only.
When will there be support for XXX N54 equipped BMW's?
Here are the development priorities for us right now.
1. Continue to find ROMs for 2008-2011 N54 turbo engined cars and create maps
for the 1, 3 and 5 series. This includes the xi and is. We are waiting for a ROM
to be provided for the N54 equipped Z4 to see what efforts are required. The X6
is currently lowest on the priority list for N54 vehicle support.
2. Stage2 maps for supported vehicles.
3. Finish development of AccessTUNER Pro and get this into the hands of
professional tuners (end of 1Q11).
4. AccessTUNER Race end-user tuning software will be released after AccessTUNER
Pro has stabilized.
When will there be support for EU, Gulf Spec, Australian spec N54 equipped
BMW's?
Although the ECUs may be similar, there is a significant amount of effort and
support required for each global region. There are an equal or greater number of
the ROMs for each make/model/year in each region as well as different fuel
grades to account for. Then calibrations must be developed for each of these
vehicles with the appropriate fuel grade, and further testing must be
accomplished before the release of the product. Then support must be provided to
improve calibrations based on new developments, customer feedback, etc. This is
on a region by region bases. At this time, we are focusing on developing our
full-tuning-solution for the breadth of N54 based twin-turbo based vehicles in
the USDM region before moving on to other world regions. We do not have an ETA
for support outside of the USDM at this time.
When will there be support for N55 based single turbo BMW's?
We do not have an ETA on availability of the AccessPORT for N55 vehicles at this
time. Our current priority is to provide our full-tuning-solution for the
twin-turbo N54 equipped 1, 3 and 5 series BMW's. While some development has
begun on the N55, there is a lot left to do on the N54 before we put significant
focus on the N55.
I have a naturally aspirated M3, 128i, 328i, etc. will there be an AccessPORT
for my car?
At this time we are concentrating on the 2008-2010 turbocharged 135i, 335i
and 535i. We currently have no plans to develop the AccessPORT for NA vehicles.
I already have lots of modifications and downpipes, can I get a map for my
car?
We will be releasing more maps for these vehicles in the very near future. We
are currently refining our Stage1 offerings and will follow up with Stage2 maps
once testing is completed. AccessTUNER Pro software for professional tuning
shops is expected to be available by the end of the first quarter of 2011.
Will tuning software become available? Can I get a custom tune?
AccessTUNER Pro is expected to be available to professional tuners by the end of
1Q11. We encourage you to inform your tuner of choice that you are interested in
having your AccessPORT equipped BMW pro-tuned.
Does the AccessPORT need to stay connected to the car for my tune to work?
No, the AccessPORT reflashes your ECU with a new calibration that is written to
the ECU. Once you flash the map on, you can unplug the AccessPORT and the map
will be on the ECU until you uninstall the AccessPORT. Removing the battery or
resetting the ECU will not affect the tune. You may plug the AccessPORT in at
any time to utilize the additional features provided by the AccessPORT (Live
Data, Data Logging, Performance, DTC Scanning).
I already have a reflash on my ECU, is the AccessPORT compatible with this?
Will I lose this flash if I install an AccessPORT?
The AccessPORT will more than likely overwrite your reflash, depending on
the type of reflash. Some will have to be overwritten while some can be saved
using the AccessPORT ROM saving feature. However, you will not be able to
interface with a previous flash with the AccessPORT.
Can I use my current piggyback system with the AccessPORT?
We do not recommend this. The AccessPORT is designed to work on its own as a
complete tuning solution. Introducing a piggyback system may cause tuning
conflicts and other issues. We have not performed any testing on this scenario.
I have upgraded downpipes with high flow cats or not cats at all and I am
getting a Check Engine Light for rear O2 sensor codes. Will the AccessPORT be
able to turn these codes off?
The ECU uses the rear O2 sensors in daily operation, and these need to remain in
the exhaust system for proper engine function. The AccessPORT has the ability to
keep the cat inefficiency codes from being thrown on the N54 while maintaining
proper operation of the O2 sensors when there are no cats or aftermarket cats.
Stage2 calibrations will have these codes turned off when they become available.
I just tried to install my AccessPORT and it is telling me that my vehicle is
an "Unsupported ROM Version" and won't let me install, what should I do?
You have encountered an ECU that we have not yet added support for. However, the
AccessPORT is able to download your vehicle's ROM which you can email to us and
we can then add support. To download your ROM, follow the instructions found
here:
http://cobbtuning.com/info/?id=5848. Next use AccesPORT Manager to save this
file to your computer. Then email the file to
rom@cobbtuning.com
along with your Name, Email address, Vehicle Year Make and Model and
transmission type. Once we have the ROM adding support should only take a few
days and we will email you with instructions for adding support to your
AccessPORT.
As of this time (2/4/2011) the
following vehicle ROMs are supported:
