M235i Stage 2 (Bootmod3) Logs
Backstory:
I recently installed a stage 2 kit on my M235i including an intake. I was having some issues with a "Mass air too high" and "Running too rich" CEL codes. Some hiccups and stuttering at light throttle/low RPM applications. I swapped back to the stock intake with a K&N dry filter, because I found out that these cars don't really play well with intakes that aren't in a closed box. Car seems to run much better. Although, I still get a "Mass air too high". I also got told by ProTuningFreaks that the octane in my car wasn't up to snuff and I should run a 91 octane tune instead of a 93 octane tune. Present: I flashed to a 91 octane tune and wanted to share my logs for some feedback. Full pull: https://www.bootmod3.net/log?id=5e61...0b43598fdf16fc Some normal driving with some light pulls: https://www.bootmod3.net/log?id=5e61...0b43598fdf16fd Is there an issue with my Ignition Timing? |

I found an o-ring on my old chargepipe. WHOOPS.
I put it on the new one and it seems to be a much tighter fit. I did another pull and my STFT is even higher now…. 1.26 at it’s max I believe. This is what I was attempting to fix, and it got worse?! https://www.bootmod3.net/log?id=5e64...0b43468a76b9df Any input..? My timing seems better, but there is inconsistency on cyl 3. |

Your latest log is good, I would consider swapping the ignition coils between #3 and #4 to see if the problem moves. That would tell you if it's the coil or not.

The STFT is high on my last log. I'm still trying to figure that one out. The only connections between the bolt ons I installed that I haven't checked yet is the downpipe. Is that something that could even cause the STFT run all the way up to 1.2-1.3? |

Update
I essentially reinstalled my entire chargepipe, made sure the o-rings were good, and tightened the top of my downpipe.
My logs look way better: http://www.bootmod3.net/log?id=5e6589dad10b43468a76cb69 I noticed the throttle angle dipped hard though while I had it at 100%. What's up with that? STFT looks so much better, but I still see areas of 1.05+. Perhaps the downpipe needs tightened even more. I only got about 1 full turn on the bolt because it seemed really tight already. EDIT: Looks as if the throttle angle dropping is because of a little bit of overboost. Last edited by Sliptality; 03-08-2020 at 08:45 PM.. |
