Question Just Stage 2'd my 220i, BM3 datalog


Posting here since it's more active than 2addicts

Went and got myself Bootmod3 after months of drooling. Started initially with a Stage 2 93 octane OTS map.

After a while troubleshooting i finally got connected, had a problem connecting that ended up being me having to disconnect the battery for a while and reconnect. Probably something to do having used ISTA recently, as i've read.

Relevant mods are:
Wagner 200cpi downpipe
Pipercross air filter
m235i M Performance muffler

I know i gotta get a chargepipe, and should get an intercooler, which are both on my list.

Went for a drive and warmed it up nicely, then slowly tried to push a bit to see if my car accepted its fate.

Here's the first log (didn't go WOT):

Here's log #2:

First i noticed in log 2, turbo pressure (pre throttle) is up to 24.5 psi at one point in 2nd, concerning.
Timings are very good.
AFR seems fine, maybe a tiny bit lean at times(?)

Throttle angle bounces up and down, what does that mean?

I'd love to get some feedback on log #2 if anyone has any, thanks.
