Hello,
I recently tuned my 2016 M235i 8SPd Rwd to BM3 stage 1 ACN. Only modifications I have is a muffler delete, m2 lower air box, and ER chargepipe. I want to make sure my car is running well with the tune, especially since I will go stage 2 with ER intercooler and high flow DP. I took one log 3-4 gear from 3k-6k, and was wondering if this is good or should be done differently.

Here is that log: https://www.bootmod3.net/log?id=637d...90c67e3d9c7bae

Log done on quarter tank of shell 91

Also if anyone has helpful links to help me understand the numbers/logging more that would be fantastic.

I do know that I should send data over to PTF, however I want to ensure I am logging the right data before sending it over.

Hey man. Log looks pretty solid all around. I would add the 6 "Ignition Timing Correction" parameters so it's easier to see how much each individuals cylinder is correcting easier.

Since you're an 8 speed auto, you'll want to do a log in 4th gear from 3k rpm/redline in sport+. Try to start the log right before you hit the gas and end it right as you get near or touch redline. Also you'll want to floor the pedal at 3k you don't want to ramp it up. I will provide a very useful link/forum post that breaks down logging and the parameters behind it.

Lastly, if you have any questions related to the N55 engine, may I suggest posting them in F30 335i forum as more people browse that forum and provide more input than on the 2 series one. You might get more responses in a faster time as it's more of a popular n55 platform, even though both engines are the same.

your log is too short.
you need to start at 2500-3000rpm

*Update*
Did some additional logging and sent them to PTF. They said logs look solid other than ignition timing, which they said is likely due to my IATs quickly rising with stock intercooler. They recommend upgrading the IC which should smooth it all out. I have an ER intercooler I was waiting to install for stage 2, but I am going to do it soon for stage 1 anyways. Overall, the car does feel great, although I would like to change the burble settings to make them shorter than OTS.

Here are the additional logs I took if anyone is curious:
