have a 2011 550i with ******* down pipes, and I'm getting a set of custom charge pipes made for it. The charge pipes will have bung for meth injection and bov. Had a few questions for you. I want the meth injection kit. Does the stage 2 jb4 integrate with this kit, even though it does t read all the stuff like it does for the n55 motors and such. It seems to only read boost, throttle position and fuel. And which kit would I need?

It doesn't seem to read Rpms.

Also can u explain what settings on the jb4 software can be manipulated for my car, besides the boost and wastegate position. And what each setting does. I'm bringing it to my tuner and he wants to know.

Also the open fuel loop, from my understanding the lower the number the leaner the mixture correct?

[Terry @ BMS]

Our meth integration is fully compatible with the N63 but I don't suggest meth for the platform. It doesn't really add any power.

The tuning options are very limited. The only adjustment is described in the first post. It's not going to work to tune in larger turbos for example.

[natecbarrett]

Any plans on upgrading firmware/hardware to allow more tuning options on the n63 platform? Or do i need to go with a full ECU flash?

sorry for so many questions just trying to figure out the best route to take here

[Terry @ BMS]

With larger turbos on the n63 definitely go with a full flash. Then just use the Stage1 to run meth and fine tune boost if you need either. The stage1 and stage2 tuning is not to the point yet that it could control larger turbos. If they become more popular we may add support in the future but just understand you're basically going to be on your own to tune it at this point.

anyone run e85 in the n63 motor? Terry, will the jb4 handle an e85 blend?

[Terry @ BMS]

It's not very E85 friendly in my experience.

Thinking about getting Stage1 for my N63. Couple of questions.
1. On the Dyno chart, what setting was used to achieve this result? 2? 2.5? 3? etc
2. With Stage 1 can I generally be safe from seeing any MAF or other codes?
3. Is a 40hp gain something that I will notice with my SOP meter, or will it only be noticeable at the track/dyno ?

[Terry @ BMS]

Stage1 is preset to 3.0psi and has proven to be very stable/code free. Expect around 40hp. It's pretty noticeable I think. For the ease of install and low cost is an excellent way to go.

[natecbarrett]

So i got AR *********, n63intake, and jb4, is there any settings i can tweak in the jb4 to help tune for the new additions?

Is the N63 Stage2 now available (will it work) with the X5 5.0i?

[Terry @ BMS]

I think a few X5 n63 owners have used it but it's not officially supported.

I want! I had a stage 2 in my 135i (I know, different beast) a few years ago and it was awesome. What makes the X5 different from the 550, in terms of the engine management? What issues do you see in using the Stage 2 here?

Hi, quick question here. I've been running the S2 setup on my car for a while now.

Recently, I've been noticing it feels like the car is cutting power at certain times. Until I have some time to datalog I checked to see if the car had any codes and keep seeing these pop up:


Are these normal to see?

Not looking for any help with the power cut issue yet until I get some datalogs, just wondering about those codes!

Thanks,
Matt

Have had the Stage 2 tune uninstalled for 4 - 6 months, reinstalled today and received drivetrain malfunction on startup

Have there been any recent firmware updates I can download? Unfortunately, this has been a recurring problem, and I think I am about to ditch the Stage 2...so much fun when it actually works though, tough to let go

[Terry @ BMS]

Without reading the fault codes who knows what the issue might be or how to best solve it. Once you have the fault code you are triggering it should be easier to narrow down the cause.

Yes those are normal passive faults from the IAT sensor alteration and should not show a light in dash. You can disable that aspect of the tuning if you wish per the first post but it will result in less performance.

Terry, I just purchased a Stage 2 for my 750ix. If I just run the default settings, what hp gain can I expect and is it stable/code free in this mode, so to speak?

[Terry @ BMS]

As long as the car is in good shape you won't have any faults. But so many need new injectors, plugs, MAF sensors, etc. There are dynos on the website with reflect the default settings.

Does the jb4 for the n63 still only come with one map? Is so what are the other maps?

[550i_scorp]

Hi Terry, quick question please. Do you guys accept PayPal to sell Stage 2 for N63?

[Terry @ BMS]

We don't have a JB4 for the n63.

Email the sales department for anything order related.

Hi Terry,
Just received my N63 Stage 2 full kit today, so excited to install it.

I have a questions please:

Can you send the installation instructions for the full kit (not the upgrade) installation of N63 stage 2. I looked into various website and youtube videos but nothing explains it from stock 550i to BMS stage 2.


Thanks a lot

Stage 2 installs just like Stage 1 with a connection to each of the two TMAP connections on the front side of the intercoolers. Then you add in the 8 wires to the ECU per the upgrade instructions for Stage 2.

Got it! Thanks for the reply @335ilurker
Everything is installed now. I have a bluetooth kit with it. So my question is: Should I connect BMS S2 first to my laptop first? I mean is it OK to skip the PC step and go ahead to coonect it to bluetooth kit?
Thank you very much.
