Hi, I have a 2013 335i e92 with the N55 engine. Car has around 28k miles and still covered under factory warranty (build date 05/13). I love the car but have been wanting to squeeze a bit more power out of it without having to install parts and such. I was looking over the forums and I saw many tuning options out there but have yet to see anything for late year e92s with updated DMEs. Is tuning possible on these cars? I'm not looking for high hp numbers (+400whp), just something quick and reliable. Maybe around 325-350whp? Thanks in advance.

Bootmod3 is the only option I know of right now really. MHD will be out sometime in the future. JB4 is an option if you want to go that route.

[nOEMm]

whether you are looking for "400+" or not you will never see that on these cars anyway unless you dump over $3k into a turbo upgrade and install, just wanted to clarify that. All tuning options out there right now for n55 will put you max at roughly 350 which would also necessitate supporting fueling or bolt-ons even though as JETmn stated, not many of these options are available for your DME yet (flash tunes that is). Your best option right now is a JB4.

Are you looking for flash only tunes? If that is the case i am not aware of any tune that is compatible with your car yet. (MHD were working on it)

Boot Mod 3 is not compatible with E chassis, only F chassis.

You can also get a Jb stage 1 or JB4

Once MHD unlocks it for your car, I'd highly recommend getting MHD with a custom tune from Ken@WedgePerformance he's been doing a great job with my car and made it way faster + smoother. I went from JB4 to MHD with the OTS maps and now to Kens tune and This is the tune I'm sticking with

The jb4 wasn't very smooth, it FELT powerful because the boost came on all at once but the MHD was honestly probably just as quick but it felt much smoother. It was a bonus that I could use my p3 vent boost gauge with the MHD tune since it wasn't a piggy back tune. Once I flashed the first OTS map, I decided to sell my jb4.

But if you're running meth and stuff I think the jb4 + mhd backend flash is the best

thanks man for the review !

you are totally right about jb4 only.
the boost comes all at once and it feels fast but afr and trims are bad and its it wasnt very safe long term for my car

i flashed the mhd backend flash few days ago and it feels a ton better

its as quick like you say but power delivery is wayyy better

smooth and linear but still damn fast if not faster

i bought a meth kit so i guess ill stick to jb4 + mhd backend flash

have you tried this combo ?


im wondering if stage 2+ map mhd would be quicker than jb4 map 2 ?

[cbc03]

Thanks for your replies guys! Yes I know I will eventually need supporting mods (intake, downpipe, fuel upgrades, etc) to break a certain hp level but I would much rather stick to ecu tunes as this is currently my DD and I want to avoid modding to the point where it is no longer reliable. So it looks like I have two options at this point:

-Wait for MHD to unlock my DME
-JB4

I've read both good and bad about the JB4 and honestly I don't like the idea of a piggyback system as I've had previous experience with one (not on a bimmer) and it turned out to do more harm than good. So I may just have to wait for MHD. Would you guys happen to know if the DME will need to be removed from the car for the unlock? Is it at all possible for these DMEs to be unlocked while on the car?

Thanks

I started with the JB Stage 1 tuner for my N55, but switched to MHD when it was released. I'd suggest waiting and going the MHD route. It has great power , smooth delivery and the tune options are really nice too.

My mistake, I forgot the coupe switched so much later than the sedan.

Yup, my first mod was the JB stage 1. Definitely agree to go with MHD when it's good to go [for the OP].

By the way.. nice avatar cjd. I'm a big Alex Grey fan..

Little sucker MEVD1726

Like I said before, on a different thread, I think BMW locked down this DME to pull some extra Ca$h out of their PPK Flash, but WHY? my mistake is that I did not research enough before pulling the plug on my 13' 335i.

I'm desperate too like the OP and wants MHD to unlock this sucker asap.

This might be a silly question, but how do I know which version of DME do I have? My car's production date is 4/24/2012, not sure if I am a MEVD1726 or MEVD172.

Follow the directions below. Whichever DME has parts available to purchase is the version you have.

Q: How can I determine if the DME is directly flashable or needs a one time bench flash?
A: got to http://www.realoem.com/bmw/enUS/select and enter the last 7 digits of your VIN in serial number. Click Browse parts the ENGINE ELECTRICAL SYSTEM and check both CONTROL UNITS > MEVD1726 section. If the it says "No parts found matching your car." you have a MEVD172 which is directly flashable.

I've had JB4 with 3 other cars. Got wind of Frank Smith at Tuning Tech in Crofton Md. No bugs. Much much better and consistent than JB4. Flash tune. Worth the money hands down. Check out my numbers in my sig. I just run 93 so check him out. When I was there last summer there were 2 people waiting to get tuned from NY. Worth the trip for sure! Just have your CP installed before you go down.

mind sharing a log sir ?

I'm not that savy with tunes and all the details. He just took the DME out and worked his magic, put me on the dyno and dialed it in. I told him I wanted torque especially so 511 on the last run was I got. He said under no circumstances punch it from a stand still. Otherwise, I need a new differential. I'd have to upgrade to Quafe I believe in order to hammer it and smoke all the late M3's. All I can say is that it's a constant and continuous pull and never seems to let up unlike JB4 which is a spike and falls off. The best thing is I haven't had any issues at all.

To answer your question about MHD...not sure. Logs...not that into this stuff. I don't track my car so it's just a DD. Actually I'm bored and want something else. Tired of the DP noise and exhaust. Just want something normal and fast. Going back to a 550i I think...or wait until I find the right 2015 M3.

oh ok thx the info bud !

yea i know what you mean...sometimes a fast car stock straight outta the box is ideal but i found learning about the n55 motor and its tuning potential is very interesting...dont get me wrong i would get a porsche turbo s and call it a day if i had the money haha

yea 511 is too much torque to floor it in 1st that for sure !
post a vid maybe

I am in the same boat as the OP.

I went ahead and got the JB4 for my '13 after 3 weeks of having it. As soon as MHD finds a fix for our DME ill be flashing that and probably keep the jb4 as well. The JB4 does seem sort of jerky so would love to try out the MHD since i keep hearing that its smoother.

[jlegelis]

>> As soon as MHD finds a fix for our DME ill be flashing that and probably keep the jb4 as well.

What's the reason to run both JB4 *and* custom map? Seriously, that would seem to me to seriously complicate matters... Either let the JB4 do its thing, or let the custom map do its thing, but I can't imagine a scenario where I'd want two entirely separate controllers to manage air, fuel and timing at the same time! It's like having two people with their hands on the steering wheel driving the car!? Can someone provide enlightenment?

Most people that run JB4s now run them in tandem with a backend-flash [not a standalone flash] - allowing the JB4 to 'only' control boost, while the backend-flash takes over fueling, timing, VANOS, etc. BMS supplies the backend flashes [e85 bef, pump bef, PI bef, etc]

You're not supposed to run a standalone flash with JB4 though, as that could get rather wonky.
