Looking to get a remap for my 335d. Does anyone have experiance with the JBD from Burger Motorsports?

I've had my JBD for 4 days and my car is noticeably faster. I had it on the stock setting for 10 minutes before I dialed it all the way up to 100%. I have not thrown a code yet.

Mine is running great on 100%. No problem pulling away from a stock 335i. 0-60 in 4.5 seconds, and 12.9 ETs.

Here is some info on the JBD. Its a great inexpensive way to add some serious pep to the D.

and a dyno...

Thanks guys for the feedback. Sounds like this is the ticket. I am going to pull the trigger and get it comming ASAP. Can't wait to see how this performs.

To clarify, I don't think the JBD is considered a "remap." It's a tune box which tricks the rail pressure sensor into delivering more fuel.

You can't go wrong with Burgertuning

Somebody correct me if Im wrong, but I think the jbd works like the jb+(for the i) it trick your car into thinking your in higher altitudes so you run more boost.

No, the JBD remaps the fuel curve and only slightly increases boost pressure.

Does it eliminate that lag at tip-in I felt in the X5 35d?

Yes, throttle response is greatly improved.

Looks like I will be getting this when I get my diesel X5. I wonder if only downside is more fuel consumed, but going easy should alleviate that! I like to have the GO-ability when I want it and sip the fuel when just tooling around.

No, I believe the JBD works like most diesel tune boxes (Mike correct me if I am wrong here). The JBD intercepts the high pressure rail sensor signal (that's what the JBD plugs into) and it sends a different signal to the ECU which demands more fuel pressure, in otherwords it tricks the ECU into raising the pressure on the high pressure fuel pump which results in more fuel being delivered and that's where the power comes from.

As I understand it, that's NOT a remap in the traditional sense. Diesel tune boxes do nothing more then by-pass the rail sensor and deliver a signal to the ECU that tells it to raise fuel pressure vs the ECU giving a comand based on it being reprogrammed.

With slightly more aggressive acceleration because of all the additional power and according to the OBC, I get better gas mileage. I'm not sure if it's completely accurate. I have read that it will take time for the OBC to adjust and recalibrate itself.

I think cssnms is correct. I found a pretty good writeup on the differance between remaps and tune boxes. Enjoy the read.

If you plan on running it 100% be sure to include the scan tool option to clear codes.

That was a very interesting read. The jist of it seems to be that remaps are preferable to tuning boxes because they work directly with the ECU as opposed to tricking the ECU, and therefore put less strain on the engine, injectors, and other supporting engine components. Perhaps somebody more knowledgeable can chime in and make sure I'm getting it right.

In any case, there are only 2 things holding me back from getting a JBD. One is I don't want to risk anything with my warranty. And the other is concern about long term reliability. Many people are running the JBD and are very satisfied, but what worries me is what will happen after 50,000 or more miles of running the car at a greater-than-factory power levels. Perhaps that's not as much of an issue for someone who's on a lease and planning on changing out of the car in a few years, but I plan (and hope) to keep mine for a very long time.

I don't claim to be more knowledgable then you, but in a nut-shell your observations are correct. Although a remap would be more desirable IMO, I believe this to be relatively benign way to increase power in your diesel.

I believe the repracutions/risks of using the JBD are lower then the gas juice box variant. Diesel tune boxes place extra load on the high pressure fuel pump and your concerns about long term reliability as it relates to these added stresses are valid. That said, there are tolerances built into the various mechanical components, now whether or not the JBD exceeds those tolerances I don't know. I would venture to guess that one would be well within those tolerances at the base setting.

Ditto, would like to see long term data/issues

What kind of mileage increases are you seeing?

Subscribed and can anyone here verify if the BT scanner can only be linked to one VIN or up to 3?
