BMW N54 AccessPORT v4.01 BETA Maps Available

COBB Tuning · 03-22-2012, 07:31 PM

We have just released a minor BETA Off-The-Shelf Map update for the BMW N54 AccessPORT. The new v4.01 maps correct the DME logic that was causing DTC P2D59 codes as well as addresses the under-boost issue some vehicles were experiencing.

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 v4.01 maps are finalized and come out of beta.

Maps are available in the BMW AccessPORT Map Database. Simply click the red BETA Maps button, review the acceptance page, and click the I Accept button to be taken to the BETA v4.01 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.

Got these from Jason when I was having boost issues using 400. Much smoother than 301 on my car. Power feels about the same, its hard to tell, but definitely a better map!

I ran stg. 1+ Aggressive at the track over the weekend and didn't experience any issues (none noticable anyway). Power felt goooood!

Running Stage1+FMIC. I can definitely feel the power! Throttle is a lot smoother with quick response.
