Hi, I'm relatively new at all of this so thanks in advance for reading.

I have a 2012 335i MT with JB4 and ER Chargepipe. Yesterday I filled up with about 3.5 gallons of E85, and the rest of the way with 93 octane. I set the JB4 to map 5 and did a couple of logs on the highway. It felt like the turbo wasn't fully performing. It's felt that way on Map 1 a couple of times too. I'm starting to suspect I might have a leak somewhere or a bad plug.

The two attached logs are from pulls in 1st, and then 3rd gears. Both look like the map changed from 5 to 4 and back to 5 (which looks odd). And even my targets look really low (in addition to the boost levels looking low given the throttle levels).

Is this just user error on my part? What are some next steps to diagnose if there is actually any problem?

Don't see any logs attached. Also, you shouldn't be running anything higher than Map 1 without a DP.

I wasn't able to upload the CSV files individually, so I zipped them. Looks like it went through though

Best to post the csv file on N54tech--there you will get the best analysis.

Good point. Here is a link to the thread in case anyone wants to see where this goes. Thanks!

Your log says E series btw. You sure you have the right settings/firmware?

That is a very good point. That probably has something to do with it. I'll update that and try to get some more logs later and see if that helps. Thanks

Looks like Terry got back to you and said to fix your settings. Have you done that?

I stand corrected.
