Newb here in Milwaukee

I've had fueling issues since I bought the CPO car last year. Romp on the car, CE light, DCM stored codes, BMW service checked things out and deemed all to be OK initially. Next trip in they swapped all 6 injectors, 3 weeks later they swapped 2 more, and I've got another appointment in early May and I'm pushing hard for a swap of the high pressure fuel pump. In my mind that's the root cause/underlying culprit. My DCM is currently storing 29F2, 29E2, 2D2E and 2E9F.
I've not strapped the car to a dyno yet, but suffice to say the car woke up nicely. Just going from 8 psi stock to 13 psi with JB4 map 1 put a grin on my face. On map 5 after the DCM/JB4 learned about the octane level (3 freeway on ramp pulls from 2k rpm to redline) my AWD car was breaking wheels loose during hard acceleration & throwing traction control warning lights.
The BMS back end flash is a bin from Burger which can be loaded via Cobb A/P or by using the bimmerboost free flash utility and a BT cable. More info can be found here. N54tech.com is more or less a JB4 specific N54 site, lots of good information there if you've not found it yet. And to echo what i_love_cars said, Terry Burger is an awesome resource.
The JB4 has a ton of capability, my current use is very basic. Once the fueling issues are ironed out, I install the parts waiting in my garage plus do an upgrade of the low pressure fuel pump, the car will be making some decent power. I'm also considering meth injection sometime down the road.
As an aside my KW variant 1 suspension parts arrived yesterday. That will most likely get installed in early May, today my car is at a body shop for some paint work as my drivers side rear quarter panel got scuffed over the winter.
What fueling issues are you referring to? What kind of power are you seeing with those mods and 30% E85?
Also, how does one go about getting the "BMS backend flash" that I hear about on the forums? Do I have to purchase the COBB tuner then?
I'm long out of warranty, so that doesn't bother me

Great to hear! I think I know of a guy who can do the BMS back end flash for me. Not really sure what the flash entails, but I'm interested in finding out.
Do you have a build thread? Hopefully you get those fuel issues sorted... HPFP is definitely something to look into.

It fills my heart with joy that my first thread has inspired more talk of people spending money in the best way possible: further modifications to their N54's

Welcome, but I would stay away from MM, they couldn't figure out how to S/C my M3.

Interesting. I've been using them for some basic maintenance stuff as well as the DPs and FMIC install on my car. Haven't had any issues yet. But that's basic stuff.
As soon as I move in a month and actually have a garage again that I can work in it will be a non-issue because I'll be able to get back to working on my own vehicles
What couldn't they figure out with the S/C ?
