    I have incurred overdraft notices at the Bank of She Who Must Be Obeyed.

     

    This describes my life from time to time.  Back when I was a Supra guy, the car became the other woman.  It finally had to go, as She Who Must Be Obeyed decreed it so. 

     

    These days with the BMW, not so much as I don't spend night after night in the garage under the hood doing gofast stuff.  The occasional weekend day under the hood/under the car, but the addiction has passed and I'm in recovery these days.

    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 :)

    I'm looking at getting the latest JB4 with the 2-step cable and some downpipes... then I can run E85 :)

     

    Thoughts on JB4 vs. Cobb? I'm glad I have a K&N drop-in air filter... I was going to get the BMS DCI, but I've heard similar stories of a good drop-in filter being the best.

     

    Currently my only mods are the jb4 and bms dci, and I run around 30% e85 with map 5 on the jb4.  If I could just get rid of my fueling issues the car would be much more fun to drive...

     

    For stock turbos a drop in filter will more than suffice, I went with the dci because I like to hear the spool and it looks nice when you pop the hood. :)

     

    I consider the Cobb A/P a tuners tool, while the JB4 is more "out of the box tune" while running the generic maps.  Map 5 is self learning, and there are some back end flashes which can be used via the combination of JB4 and A/P.  I used an A/P on my last car (550 crank hp Subaru Legacy GT) and loved the device for switching between 91 octane and e85 maps.  My tunes were pro tunes which were then stored on the A/P.  

     

    The downside of using the A/P, esp if you are under BMW warranty, is that it leaves a footprint in the DCM which says "I was flashed", whereas using the JB4 it's 100% stealth.  The DCM only sees max stock boost (8 psi in my case) while the JB4 produces 16-17 psi.
