Great update thanks for showing love to the N54 guys!! I don't have to worry about any burble settings since I have the 335is mufflers they burble all the time lol.

Going to try out antilag sometime soon. The antilag on the Jb4 is delayed on release, which is just no fun. I just need to disconnect the QD I have to the temp sensor.

Love this update thank you guys for the continued support! I know all these fresh options had to take tons of time and testing. I took a chance and ported one of my tunes over last minute for the track last night and was able to get boost dialed in for the most part. Very convenient for this purpose alone. I just set up a few different settings within the map selections and hot lapped it. Definitely got way more runs in than I normally would flashing after every other pass. Track prep was another story…

Is there any more info on the custom boost control strategy? More specifically how the P/D factor tables should be setup. It may be the description just messing me up but I am assuming they should be similar to oem style with both +/- on the axis? Is adder airflow still used per map? Or is this strictly Base % + P/D factors? If you would share some examples of functional tables that would be great but I understand why you wouldn’t want to also. Thank you again for all the hard work!

Adder airflow is only used per map if you use the OEM wgdc tables. The custom P/D tables should be setup similar to OEM yes, with positive and negative error columns. Just pay attention as the units as psi

Note to antilag users: be on a clear road the first time you try it. My car will hook from a 40 roll, but with antilag set to 15psi, it is immediate wheelspin and power slide inducing. Fun tho :)

Jake, I couldn't glean from the user guide - with map switching, it says to use a non ethanol map on the map switching. Is it possible to have multiple flex fuel maps, or even the same map multiple times and use the "power percentage" feature? I know multiple flex fuel maps seems silly, but it would be nice to have a WAG mode, where even if there is E60, it limits boost to 10psi or something.

Finally - with map switching, can you have separate flash time options - i.e. burble enabled, burble off, different launch control rpm?

OTS multimap will allow FF per map, and allow power limiting per map. And you can have different burble per map (can do with custom tune now, flash option coming). Launch RPM is not per map though.

I've seen similar issues, can you share any info on the cause and fix?

The trims freeze at a certain % or 0% stft (open loop) have a few varying causes. But all are basically due to the DME thinking it detects some type of unexpected dynamic lambda condition.

Can't give details on the fix, but it is applied automatically to all flashes now

Bug or? Map switching on custom tune. Volume down+Channel down > Once engine light flashes for map selection the CIC screen goes blank until map is selected, I lose all audio. Vol up on steering or headunit doesn't bring sound back unless i reset the headunit or goes completely to asleep before ignition on.

No such issues for cruise stalk though.

Same thing for me, I went for cruise stalk option.

The radio / iDrive off is intentional, so that changing maps doesn't change your channel, etc. 2009+ iDrive should turn back on when you exit mapswitch mode. Regular radio you have to turn back manually
