Beta maps for the BMW N54 AccessPORT are now available for download and evaluation. These v4.00 BETA maps were developed to provide smoother response, more power and address the 3k RPM "surge" that some users have been experiencing. In addition, Stage1+FMIC BETA maps have been released for those cars with upgraded intercoolers, but without the necessary exhaust modifications to satisfy Stage2 hardware requirements.

Please note that these are BETA maps and may or may not perform as intended across all vehicles. This BETA release is intended to gather feedback from early adopters and incorporate it into the maps prior to final release. If you are unwilling to experience potential performance inconsistencies or provide constructive feedback on these BETA maps, please continue to use the General Release v3.01 maps until the v4.00 maps are finalized and come out of beta.

Maps are available in the BMW AccessPORT Map Database. Please clear your browser cache and refresh, then simply click the red BETA Maps button, review the acceptance page, and click the I Accept button to be taken to the BETA v4.00 maps. If you are unfamiliar with the process of downloading maps, transferring them to your AccessPORT and flashing the ECU, please review our Step-by-Step Map Download and Transfer Tutorial.

From my perspective these are better maps, just tried them and I think the pause/surge at 3k rpm is gone. Smoother pull.

Well done Cobb well done

Which throttle map did you try, Stock or Linear?

[MDORPHN]

Doesn't look like the Stage 1+ beta maps are (yet) available for the 1M.

Am I wrong?

It seems like the I761S link (http://www.cobbtuning.com/AccessPORT...eta_maps/I761S) contains the maps for I742S.

If you don't see the Beta button, you might have to press F5 a few times until your computer loads the new page data.

ahhh need moar reviews!

lol i'm tempted to go ahead and download the beta maps but I've been having troubles with my car for the past 2 months and i FINALLY got the issues worked out so I'm enjoying the v.301 maps now fully haha don't want to download beta maps and run into problems =[


btw, for the 3k rpm "surge" ... are they referring to the feeling of moar boost that hits around there? (kinda feels like vtec?) i actually like it to be honest... but thats just me haha
