First time datalogging
Hello, I'm very new to datalogging and reading these numbers. Can someone tell me how everything is looking? I have a 2014 M235i RWD auto with a drop in k&n filter, JB4 on map 5, and VRSF ** running on 91 oct mixed with e85 making it around the ballpark of e30. I did a few pulls in manual, sport + mode. How do my numbers look so far? Is my boost supposed to be around 12-13psi? I thought map 5 had higher target boost?

I would recommend you to create a datazap.me account, and use that to upload and share your logs

Here's the datazap logs:
https://datazap.me/u/mineralm235i/jb...log=0&data=1-4 I just wanted to make sure the AFR is within good range during WOT. Someone else also told me my avg ign is ~4. Is that a good or a bad thing? And is my boost at the right PSI for map 5? |

I can only assume it was when I let off the throttle once I hit about 7k RPM, if that's what you're referring to. For those runs, I started off at 3k RPM and WOT til 7k and let off.
Update: I did another couple runs tonight but I changed to Map 2 to see if it's more consistent than Map 5 and to see how I like it. This time I ran in manual mode again, in sport mode starting at gear 3 at 2k RPM. I am noticing that my AFR is staying around 12.8-13.5 during WOT. Is this normal? I believe during idle, it's supposed to be 14.7 ideally so I thought Here is my new log: https://datazap.me/u/mineralm235i/1s...=0&data=1-4-18 |

Boost overshoot. Not entirely a big deal unless it could be felt where there was a drivability or physical powerless. Plenty of turbo drive by wire cars use throttle to modulate power.

Would throttle closure due to boost overshoot negate the benefits of a boost-only piggyback (Dinan Sport or BMS JB+)?
