Below is a log, any advice or guidance would be greatly appreciated! Thanks in advance.

We don't use datazap. You attach the JB4 CSV file to the post directly.

I think you have that backwards. It's under boosting. Probably due to the lower FF and duty bias settings. Need the hybrid turbo duty bias upward slope...

Well initially its overboosting because surely map 2 shouldn't be hitting almost 20psi? Then tapering down to below 10psi
What should I do?
My car is stock turbo. Running the PPK, ********, intake, chargepipe, Jb4, N20 Tmap sensor, Walbro 450 LPFP. I have removed the BEF since the log due to the car not feeling right. Throttle was also very jumpy |

You're just reading the log wrong. You can see the target is 19psi there right in the log. If boost was going substantially over target and staying there you'd have an over boost situation. You have an under boost situation.
Map2 with a BEF and/or 3.5bar TMAP sensor is 19psi peak with a strong taper to redline.
For stock turbo turn FUD to 0, so you get the stock turbo duty bias profile at duty bias = 50 across the board, reload the BEF, and relog. Map1 if you prefer.

Okau I understand
Let me reload the BEF and get a log done and then will post it back here again and have a look |

Probably high IATs pulling timing. Did you log the runs? If so post them up in the support section.

Need logs to see what's going on and why.

As I suspected the IATs were really high. The fuel you were using probably isn't great for 15 psi either. Timing was pulled and the car started running pretty rich. I assume the computer does that to cool the IATs and save the engine. If you want to do longer WOT pulls I would upgrade the intercooler and add methanol injection.

Since I've done the N55_ISO_5_17_T5.hex update, whenever the car is ice cold ( like sitting over night) I get a "service engine soon " light on start up. I check and clear the codes and it happens again the next day. Any suggestions?
Same codes each time:
3106 ******* ******** installed
387F
2C90 Blow-off valve mechanics --ignore tuner code
2011 e90 335i VSFR charge pipe, ******* down pipe and BMS CAI

Hey Terry, recommended by Ando was to unplug the MAP connection with the latest firmware, which has successfully made the 3166 tank safety ventilation code disappear on my late E series N55. Seems like that’s the fix as a few others I’ve talked too have had the same results!

Are you saving the settings after you set it? I’ve done that a couple times where I forget to hit save. |

Update latest firmware, unplug the MAP sensor connector and plug in the stock one.

I don't understand. I've updated JB4 latest FW already. You're saying I should plug the stock TMAP connector in and then update the FW? Once updated, plug the JB4 TMAP connecter back in like normal? |

No, the MAP connection on the intake manifold. Unplug it and put the stock one in.

Gotcha.
Unplug MAP connection (JB4), plug in stock MAP connection.
Run FW update on JB4
Restore original JB4 connection
I wonder if this is part of my issues. |

noooooo
Unplug the JB4 map connector, plug in factory and leave it like that. also do the FW update.
Did that to mine tonight to get rid of the 3166 code. |
