Hey terry I got a question for you. I have a 07 335i with a bad dme now my question is can I put a newer one in there is an 08 and 09 both at the junkyard. Can I use them and just change the timing though my jb4. Or do I need an 07 dme.

if you are going that route might as well upgrade to MSD81

So the dme from 09 335 would be better to use. Rather Than trying to find 07 dme. I’m running d.p., exhaust, charge pipe with bov, stage 2 turbos, stage 2 bucketless lpfp, dci , Mmp inlets , vrsf outlets, fmic, rb pcv, occ, jb4, mhd bef. So msd81 better than msd80?

you will have to Re-Code your DME either way, doesnīt matter if MSD80 or MSD81. But the newer MSD81 is way more reliable, so from your side i would go for it. It is also possible to buy full kits of DME+CAS+Keys, then you wouldnīt Need to Code. But i think this is the wrong thread for this discussion.

Best to post in the support section.

What mods do you have? You have some overboosting in the upper RPM actually.

JB4 firmware is really old, update that to the latest one and follow the directions here:

I see these >

- do a better log(s), on 3th or 4th let's say from a little bit under 3k revs to redline with WOT
- your lpfp log value is 48, so problem with sensor?
- you should lover DB at range of revs as you're slightly overboost.
- set All cyl logging in setup menu

Did you follow the initial settings for hybrids? I mean FF learning should be off.

Looking through the most current release of Back End Flashes, I only see E85 or greater maps for Hybrid Turbos. I'm installing Tomioka Racing 19Ts and I'd like to use a Hybrid BE flash but I don't have regular access to E85 so I use 93. Is there a hybrid flash I can use?

OK, so I just read through the entire 21 pages of this thread. Looks like Pump Flash in Map 2 to start out with is the way to go. It would be good to add that information to the original post to keep others from asking.

Now that I look at it again, you're right. It just wasn't that clear to me when I first read it. I don't mean the Map 2 part, I was only speaking about which BE Flash to use. It doesn't specifically say even with upgraded hybrids to still just use the proper octane flash meaning there isn't one for the hybrids if you're not running E85, PI, Meth etc. This is a thread about upgraded twins though so I could have assumed I suppose but I did not. I still think that line 4 could explain that a little more clearly.

I was also not bitching about reading through the entire thread. I was merely stating that I had done so to try and be as informed as I can be on the situation rather than just rely on the group to answer my questions.

Default Just installed Pure Stage 2 turbos. - 05-31-2019, 01:15 PM

Hello everyone.

A little question; My Mecanic just finnished install new PS2 turbos on my car, 2008 N54 E90xi, and i already have a JB4 installed.

I want to know if i can travel 30 miles slowly to get home without installing the BEF without dammaging the engine. I do not have the room there to install the power supply and i want to do the flashing at home without a hurry. I planned to use MAP 5 while riding home.

Once home, i'll do the BEF, and Set MAP 6 as the settings in the first page of this trhead. Will it be ok ?

Just leave it on map 4 if your really worried, I wouldn’t worry about map, it’s not going to target anything your turbos can’t handle I didn’t tuna BEF for a while

Thank you for the advice.

My main concern is about fuel/air and others parameters other than boost.

Sorry missed the post. Log doesn't have default duty bias and options setting in the first post.

What turbos?

I'd start with RACE and evaluate it. Main thing is the JB4 side settings so boost control is correct. Those are in the first post.
