N55 JB3 from BMS question

[CLV0009]

So I recently traded in my 06 330i sedan for a 2011 135i DCT, loving this car!!!!. I've been reading thru some posts and exchanged a couple of emails with Terry from BMS and it seems like the stage 1 kit is a good and safe mod for the car with some modest hp gains (50)?
So I would like some opinions from fellow members who have the same car with the stage 1.
Do you drive around with engine codes popping out?
Gas mileage afected horribly? I expect a decrease as I would be gsining hp.
Have you taken the car for service at dealer and have they detected the programming? warranty issues?

thanks for the insight.

Before visiting the dearer ALWAYS remove the jb and use the bav tool to clear any potential tuner codes, if not then kiss your warranty goodbye

I had it dyno'd this weekend and was 18% more power than a stock N55. I was running default JB3 setting with +4psi.

I strongly recommend the JB3 for if you just want you N55 to be more responsive and a lot faster. Wheelspin is an issue with extra power...WOT on 1st will cause back to swing out a bit, but all great fun!

Thank for the info, how would I know if my car the new BMW DME update?
wheel spin sounds great!!!! will hurt later in the wallet (tires) but is all part of the fun I guess.

I guess I would have to become very good at using the cantool to clear all the code before going in.

Basic test to see if you have the DME update, turn off the traction control and you should have the newer yellow icon of a skidding car, not the yellow triangle

So I did the test and I dont have the latest DME update, should I go to the dealer and have it done or wait until I get the JB3 and do it then?

dealer will not do update on your car unless your car's VIN falls into recall range.
I have N55 built on Oct 2010. Mine doesn't have latest software but I cannot get latest update because it does not have any campaign listed for it.

My car is 2011 with n55 built in march 2010. Have not received any letters for for any updates. So my question is, if we install JB3( or is it JB4 now?), we wont gain much power ? Does someone know the diiference between the power gain with this tune for n55 with old software vs the new one?

[stevenc]

I think there is some misinformation in this thread. We really need Mike to chime in here.

Im "think" the JB3 works fine not matter which dme software you have. The JB+ for the N55 makes LESS power with the newest dme software.

[CLV0009]

I guess while I wait to break in the car BMW can send me the letter, once break in is done I will order the JB3 and get cranking with this bad boy.

Ive been on the jb3 for a few months now, never any issues with the car and I daily drive it. Need to get that DME update though :]

I havent read any driveability issues with the JB3, are there any out there?
I'm gonna inquire at my dealer about the software update and see what happens.

JB3? Do you mean N55 Stage 1?

Has it been renamed recently?

I had the pleasure of having Terry install the N55 JB3 on my car this morning. I also picked up some wheels spacers, 10mm for the fronts and 12mm for the rears. I can't thank him enough for the excellent customer service he provided. I could not stop grinning on my drive home from work tonight. Thanks again to Terry and the whole crew!

lucky you that you could have them install the JB3! couple of questions
-Do you have the most recent DME update done?
-whats the reason for the wheel spacer? are yo running those with the OEM wheels?

Enjoy the car!!

-I do not have the recent DME update.

-The wheel spacer is to give it a wider and more aggressive stance. I was not planning on purchasing them but went ahead when I saw one of Terry's 135i's. I personally can tell a difference after installing them. Overall, It improved the handling capabilities of my car: Corner entry, middle, and exit. I just replaced my stock OEM run flats with Hankook v12 Ventus tires. Bumped up the fronts and rears, 225's in front and 255's in the rear. No rub issues with the setup I have.

I have yet to get mine working..everythime I install I get an engine malfunction light...last time we even had the laptop connected and it couldn't find the JB3...guess I need to ship my car to Terry...

If you can't do it yourself go find a BMW mechanic and pay him 50$ for labor. Simple as that.
