Map 5 issues

335xi_full_throttle · 10-24-2019, 08:34 PM

Hey guys, I've been searching the forums and also other forums looking for an answer for my problem, but I have yet to find a post with a similar problem like mine. Anyways the problem is with my JB4. It seems to over-boost only on map 5, every other map works fine. When it over boosts the car sounds like it's misfiring hard. This problem started after I updated the firmware, but I did make sure my settings matched the ones posted on n54tech. I do have some logs that I will post and while I'm no expert at reading logs. They don't seem to show any issues or even high boost pressures. I might have to do another one. If anyone can provide insight on my issues that would be great.

I believe that's what the link in my original post will bring up. Is it not? Sorry first time.

Set everything to default settings. Should clear things up. Post another log after you do so. tmap is set to 15 for example.

Sounds good.

Well I checked my settings and everything seems good. I took them from the N54tech website. One thing I forgot to add is that only in map 5, I'll be cruising and when I use Cruise control and bump it up 5 mph it'll make about 7-9psi of boost, which isn't right.

I didnt go over everything but your tmap was definitely not right.
Just went over your log misfire0-1 or something like that.
Duty bias is all wrong so is fuel bias , tmap is at 15, and dwp in one log is 96 and another is 90.

Ok so I checked my settings and I'll post a picture of them also. And I went for another log. This time I can clearly see on the graph in map5 that it's boosting to 20psi which is definitely to much for 93oct.

Here is the log: Https://datazap.me/u/335xi-full-thro...0&data=1-4

Here is the log: Https://datazap.me/u/335xi-full-thro...log=0&data=1-4

Tmap is still at 15
Either 0, 1, or 2 are the values that should be in there. If stock tmap =0
3.5 bar / N20 =1
Also select the 6cyl timing that applies to you to see how all cylinders are behaving.

Oh ok sorry. I'll put 0 in and give it a try.
