BMW N54 AccessPORT Beta Race Fuel and E-30 Maps


COBB Tuning is proud to announce the immediate availability of Beta Race Fuel Maps and E-30 Blend Fuel Maps for Stage2+ AccessPORT equipped BMW N54 vehicles! Gains of 50% more power over a stock N54, and +40HP / +45lb-ft torque over our Stage2+ Aggressive maps are just a flash and a fill-up away. These Race and E-30 maps provide the ultimate in plug-and-play performance for the driver looking for the most from their BMW. If your vehicle meets the hardware requirements for this map, and you have access to 100 octane race fuel, or E-85 fuel, acquiring this level of performance has never been easier. Simply download one of our free Beta Race or E-30 maps, reflash your DME with the AccessPORT, fill-up with the appropriate fuel and experience the rush of high-octane power gains.


These new Beta Race and E-30 Fuel Maps include adjusted boost levels, fuel delivery, ignition timing and base programming logic to improve performance and reduce DME intervention that conflicts with driver input. In addition, the speed limiter and rev limits have been raised. In simple terms, with the torque and load limiters moved out of the way, fuel mixtures and timing adjusted for race fuel, and driver nannies pushed aside, we have enabled the N54 to deliver big power gains and consistent power delivery with simple bolt-ons and a diet of race gas or an E-30 blend.

In order to use these maps the following conditions must be met:[*]Access to high quality race fuel with a minimum octane rating of 100 AKI (105 Ron) or greater for Race maps, or access to “E-85” and 93 octane (98 Ron) or greater to achieve a blend of 30% ethanol for E-30 maps[*]Requires upgraded intake system (DCI, panel filter or similar)[*]Requires upgraded front-mount intercooler and piping (FMIC)[*]Requires upgraded downpipes[*]Highly recommend upgraded cat-back exhaust system

With great power comes even greater responsibility, and these maps are no exception. Data logging vehicle performance is an absolute requirement when using these maps to ensure that the mechanical systems of your BMW and the quality of fuel are up to the task of supporting these Beta Race and E-30 maps. Instructions on how to data log, which parameters to log, and how to evaluate engine performance are explained in this BMW Race and E-30 Fuel Data Logging Instructions document.

It doesn't get much easier than this. There are no firmware updates required and there is no need to perform an AccessPORT Uninstall and Install. Just download the appropriate map, transfer to your AccessPORT, flash your DME, fill up with the proper fuel and go. For assistance with the map download and transfer process, just follow this Step-By-Step Map Download and Install Tutorial.

If you are ready to experience huge power gains and refined power delivery with simple supporting mods and race gas or E-30, head on over to our BMW AccessPORT Off-The-Shelf Map Database, click on the Race Maps link, and download your free Beta Race or E-30 Map to get your adventure rolling!

I've been running "hotter" ATR maps than this on my 135i with stock mids and magnoflow axle back.

Hey,

While a catback is not required, We highly recommend a upgraded cat-back exhaust system.

Cheers!

That looks tasty, and it just so happens a BP about 20 miles away sells 100.

Will you provide a flex fuel sensor like Vishnu or feel there is a need for one?

What is you opinion of the use of a flex fuel sensor and the fact that there are inconsistencies with the amount of ethanol in a tank of fuel?

I'm genuinely interested in your responses since Vishnu touts the benefits of their tune with their flex fuel sensor, but I understand if you don't respond so a "tuner war" doesn't occur.

I'm following closely the results and progress of the use of e85 with our cars, especially since the gains are almost the same as FBO with meth without the hassles that meth kits come with (installation, plumbing, constant checking of lines and filters, storage and fill-up, spray inconsistencies, etc).

a flex fuel sensor isnt needed

they have the maps set for e30 and not e85 , so that will help with the variations and im sure with an off the shelf tune it isnt set for all out performance... more or less its a great base map that allows the benefits of race gas without a pro tune

there are a lot of e85 powered cars out there that dont have flex fuel sensors and while its a great convenience, its not necessary unless you want to tune for all out performance and use cheap pump e85 (which can very from station to station, month to month)

Superb indeed! A 128rwhp delta is something to celebrate! I can't wait to see what customed ATR tuners will come up with now using this map as a base =)

Jason or Rob @ Cobb tuning, is there a "safe" mode it'll revert to if the customer forgets to load the correct map when they switch back to regular 91-93 octane?

Also FWIW, many modern FFV cars built after 2006 no longer have "flex-fuel" sensors; they use other means (means that the N54 and just about every OBDII car has) to check the amount of ethanol content.

Very good. More things for me to try when I get my car back from the body shop.
