Is it true to say that if the fuel connection on the jb4 isnt connected, that the JB4 isnt able to read fuel pressure and the built in safety of the fuel pressure falling below 700psi isnt active?

Terry @ BMS · 12-26-2017, 02:48 PM

The most important safety is the air/fuel ratio and that is active as long as the OBDII CANbus is active.

Yes, ISO won't run properly with a 0 FF. Make sure diode was cut too though. If you left it on, JB4 will learn FF down towards 0 to try to keep boost on target.

Terry, there are two OBDII connectors offered. One is cable only the other says "side connector for retrofit" Assuming the latter is the one to get for an older model that was designed for the posi taps??

Terry @ BMS · 12-29-2017, 08:56 PM

Right, for very old JB4 systems upgrading to OBDII.

I just installed a new unit and totally forgot to check, but do the new units come with the diode already removed? It currently has firmware version 12/11//3 installed. 2013 335i PWG

Hello . Sorry for my english, I'm french. I have a problem with my bluetooth kit. When I connect the application to Bluetooth, my BC command no longer works, I can not open or close the valves anymore, and I do not have access to the Jb4 menu. But when I disconnect the application, everything works normally, the BC key opens and closes the valves and I have access to the menu on the meter. In the end, the Bluetooth kit crashes the JB4. I have an other problem , when I'm on the application, the information that gives me the Bluetooth kit sometimes goes back to 0, and comes back 1 second later. They are not fluid either, she lag. Have you ever seen this problem?

@Terry

Are there any plans to Update PWG firmware up to current EWG firmware specifications.

Since the EWG_12 , Has Adjustment for those running high boost back end flash maps.
And now since MHD is out we are going to use backend flashes and higher boost levels.

Hello together and happy new year,

at first sorry for my english, I'm texting from germany, like recommended from the 1erforum in germay.

I got some trouble with my JB4. I've got a M135i N55 with PWG. Installed was a JB4 Stage2 Rev. 1.0 board with N55_FSERIES_OBDII_PWG_11_T1.hex firmware. At first i only had some trouble with the boost controller and got a error in the dashpot. Reading out the error message monitored a shortcut to ground at the boost sensor.

Some weeks later I got a big bump during launching and a error message in dashpot again. Displayed in the navi display was again an "engine problem" and reading out the error code showed, that MAP, TMAP, Flex Fuel and Boost sensors had all a shortcut to ground in the same moment. The issue occured more frequently the last time, thats why I removed the JB4. Since then, there were no more problems.

I checked the wiring and the connection to battery and ground - everything fine.
For installation I used the guide and did it in the same way.

Did anyone had the same issue before? Any suggestions to fix the issue? It seems that the JB4 board has some trouble (all connected sensor with issues..)?
M135i is quite slow without the JB4, at least I had to push hard to overtake a Ford Focus ST... damn :D

Greeting from germany

Patrick

I just want to verify if I set my FUD correctly.

F10 535 PWG - 93oct, kettyless **, map2

FUD:
bit0 - Disable in dash BC button controls -- NO
bit1 - Alternative in dash BC F10 compatibility mode -- YES
bit2 - Disable oil temp warmup protection -- full boost target when oil temps < 160. -- NO
bit3 - Disable wastegate/FF adaption learning for diagnostic purposes. -- NO
bit4 - Enable user adjustable progressive meth control*-- NO
bit5 - Disable port injection mapping tip in gain. -- YES
bit6 - Enable extra timing cylinder logging. -- YES
bit7 - Slow down CANbus sample rate - required for some vehicles with older software. -- YES

I am curious about bit5 port injection, should that be enabled or disabled is fine?

WaqasRiyami · 01-02-2018, 12:38 PM

Since you are F10 535i

You need Bit 1 and Bit 7
I am not sure about bit 5

@Terry

Would greatly appreciate your feedback.

alex90jub · **different Boxes 640i PWG vs. M135i PWG? -** 01-14-2018, 03:04 PM

A friend of mine has a JB4 for the 640i PWG Typ B. Can I use this Box for my M135i PWG 2012? The TMAP sensor looks the same.
Thanks.
Alex

Terry @ BMS · 01-14-2018, 03:24 PM

Hey guys,

Have an F series EWG firmware that features much faster datalog sampling. Can a couple of you load it and give it a whirl? Worst case if it doesn't work (no data shows) just go back to previous version.

Thanks!
