Only the Germans could design such a user interface..... user interface is CRAP..... system works pretty good.

You should see the crap that VW is doing now on their cars. Speed control to stop you from coming up a certain distance on cars and some kiind of steering assist that if it feels you are on the outside lines of a lane it will bring your car back in line.

It's supposed to be a feature that will be built into upcoming cars(at least theirs) soon

Terry does the 8/15 firmware work with the 9/16 interface. Dont have enough time to download the firmware at the moment so was gonna run it with the old firmware and new interface.

Thanks!

Question about the 'cold oil' protection mode. I know it limits the boost until the minimum temperature is reached, but are the JB4 optimizations also disabled in that mode, such as lagfix, bogfix, timing map, etc, until it reaches the activation point? Thanks

Terry @ BMS · 10-06-2011, 01:19 PM

Yes everything is disabled and the car is 100% stock until oil temps > 160.

Are there any plans to make this user adjustable? I already have the habit of staying out of boost with cold engine from driving other turbo cars year round, and I really like the responsiveness with the other features enabled, even if I don't use heavy throttle or go into positive boost. Just asking because my commute is pretty short and with winter approaching I probably wouldn't hit the min temp until right before my destination. If it's a liability or too stressful on the components I understand. Sorry if it's been asked before.

hey Terry - hopefully this isn't a dumb question. i have an older jb3 pinout and i'm looking for the detailed instal/uninstal directions. i thought i remebered something on this site in addition to what's on the bms site. does anything still exist? i'm having motor work done and need to remove the jb3 until everything is done.
thx!

Terry @ BMS · 10-06-2011, 02:04 PM

Just a change to the fueling strategy we're testing out. Nothing should be noticeable to the end user.

Maybe some day. But even lagfix on cold oil is not going to be good for them...

No it doesn't really have anything to do with that.

I don't prefer their boost, fuel, and advance curves down low and have no plans to emulate them or make any changes there. If you have any additional related questions there is already a discussion going here: http://www.n54tech.com/forums/showthread.php?t=13879

Just went to download the new firmware (great idea on the meth additive on the fly!) and noticed this:

1) Modified meth purge to display meth flow in dash. To enable purge mode go to 7/5 in command mode and with command mode open press the gas pedal down. With line removed from nozzle while purging the signal should reflect 0. With the nozzle connected to line and spraying in to a bucket or water bottle the signal should reflect a normal 40-50% reading. Avoid using this function with the nozzle and line installed in the charge pipe as spraying large amounts of water/meth in to a motor not running may result in various headaches.

I never heard anything about this til now. Does this mean I can purge my meth line through command mode now and not have to go through the VC2 in the trunk?

prelude2perfect · 10-07-2011, 07:02 PM

Wait, I just thought about it and obviously JB4 can't control the VC2. I assume then that this is only for those running the FSB/ JB4 only?

Yep.

Terry, I read a post a while ago regarding the downshift delay experienced with the DCT tranny in the 335is. Was wondering if you were still looking into ways to counteract this annoyance. Thanks.

It isn't something we've spent any time on yet, but definitely something we plan to spend time on in the future. Just can't give an ETA as its one of many things being juggled around.

Thanks for the reply. Understood, I guess the good news is that you have a lot in the works, which is great for all of us!

hey terry i just loaded the newest hex file into the car and went through all my setting making sure everything was set up the way i wanted. I checked option 9 and it was defaulted to 4000rpm, so does this mean i would be running 4psi more boost since i am on map 3? I haven't givin the car full throttle since i have loaded it cause i don't wanna over boost.

That sounds right, but you can always double check your settings by looking at your Meth Additive in the JB4 application itself.

Right, that is a +40 additive.

Caruso0644 · 10-09-2011, 04:41 PM

if you plan on going above a 40 additive do you need to adjust the Boost limit in the User settings?

Terry @ BMS · 10-09-2011, 04:47 PM

Of course!

Terry a little help.
Just back from Oman.
I keep getting the DP codes. I set the codes to map 3 but the service engine light remains.
2 The oil temps show 340ish on start up. I did the 135 change on the speedo 5 to map 1 so the map changes matched the codes/maps. Also I can't to the cooling mode (6 on the speedo) what am I doing wrong?
