Hi guys a new user and new to the JB4

I picked up 135i with JB4 installed along with charge pipe, tial and ***** ***** and FMIC all installed about 2 months prior to me owning it.

Question is can i run map O with no ill effects currently on 1) and also what is a good map to run and settings for to choose. I do not have a data cable for logging yet but will have one in a day.

No issues at all. Leave it on map 0 and get a log when your data cable arrives. Post your own thread in the support section for one of us to look it over.

Terry, I would recommend putting the release date in the title of the link to the JB4 Firmware!

ie: 11/11/2018: G5_ISO_32_12 Click Here for Firmware -->G5_ISO_32_12_T10.hex

Any chance we get a firmware update to fix JB4 menu selection for the guys running the N54 Exclusive gages? I used Menu 5 Option 7 to set it for the M cluster cal. Works perfect for the MPH menu since both are 200mph gauges. But it's off on the RPM menu since the M cluster goes to 9k but N54 Exclusive is 8k.

When sweeping on start needles even trying to go to next circle. will reflashing the firmware solve this problem? if yes, where can I find older firmwares for G4 board?
thanks

I just swapped out my old G4 board for a new G5. I never had any of those issues. Sounds like you may have a bad board or potential wiring problem providing there are no other car problems and it runs fine without it.

Yes already done, email me for it if you need.

For those running the new N54 Exclusive gauges, we've added the required programming to the JB4 under menu 5/7, in v32.13 firmware. Just email me for it if you need it as we're not ready to post it yet. The update may break those running the E90 M3 retrofit cluster so if there are any of you guys out there drop me a note too so we can figure out a way to keep both active.

Years ago you emailed me file that works perfectly with m3 cluster retrofit. I think I still have it. Do you need it?

Mailed you Terry , could you please have a check your inbox

Yes the logic is still in there. I guess since we still have people running both options I'll figure out a way to keep both active in the firmware.

Hey guys, 07 335i Running map7 jb4 MHD backend flash e85 flash on E60/E50... Question: I might be selling my car? And I want to switch back to Map5 so New Owner can run E30 or less E85 or just straight 93 Octane... CAN I SWITCH BACK TO MAP-5 without changing my MHD Backend Flash E85 Tune... Do I have to change MHD back to PUMP Tune?!? Thanks!!!

Change back to pump flash.

Hey guys! I just got the jb4 and installed everything. I truly believed I did everything.right. I had battery off during installation and all that. Anyways when I went to turn on car after plugging everything in the jb4 worked fine! I was able to go thru the different options and then as soon as I went into drive and drove for less than a minute my CEL came on and my temperature yellow came on. Then right after temperature red came on and my car went into limp mode. Pulled into my garage and my coolant over flowed... I have no idea what this issue is. I never had this issue til I installed the jb4 today. Last month I got a new hpfp and new spark plugs /coils.
Did I put a setting wrong in the menu??!

Joe_135i · 02-21-2019, 02:31 AM

Question for the JB4 phone app: If I change one the gauges to E-85 I usually get a number between 75-90. What exactly does this number mean?

Russjonesr · 09:23 AM

If you have the flex fuel sensor installed then its your % ethanol content...if not then this is the "virtual" sensor based on an algorithm. If its the virtual sensor you will need to know what % of ethanol you are actually running, then in the JB4 there is a field you can adjust so the virtual sensor reads the same.

The virtual sensor calculates ethanol, when the engine is at temp and stationary.

For example: say you are running 5 gallons of E85 and 5 gallons of regular. Assuming your regular contains no ethanol and your E85 is actually 85% ethanol you will be running E42.5. All you have to do is adjust the setting on the JB4 so that the virtual sensor reads the same. Look for the "virtual sensor offset"

piele_bps · **Trim 2 not showing -** 03-06-2019, 01:57 AM

Hello guys. Any idee how to enable trim 2 to appear in logs? Using latest firmware and interface.

Got a log so we can check it out?

Sure, here it is, sir.

Terry @ BMS · 03-07-2019, 04:30 PM

Hey guys, working on an update to how we datalog transmission temperature to avoid possible flashing conflicts when using xHP transmission software. Could use a couple cars to help test it though! If you have time drop me an email at terry@burgertuning.com. Thanks!

THE BEAST · 03-07-2019, 04:36 PM

What conflicts ? I run xHP and have zero issues flashing BEF via MHD. I dont even set to map 0, it does it on its own.

I know, never had an issue here either. But some guys insist the JB4 is conflicting somehow with their trans flash loading. I had one customer who had to remove the JB4 to flash it. After investigating I adjusted the firmware not to scan the transmission diagnostic and same person claimed it could then be flashed properly with the JB4 on map0. I can't explain why it works for some and not for all, but the new logic is better anyway. We're reading trans temp off the ECU rather than the trans.

Yeah, Ive heard of that but have not encountered it. Flashed xHp a few times until I was happy with stage 3 (have had it since xHP was first released), never had an issue flashing. Sorry couldnt be of help then.

We can have you test the new firmware anyway to ensure your trans logging is working properly with it.

Also on xhp stage 3, done it few times switching between stages and never had an issue with my JB4.

I will drop you email to log for the new firmware of that helps.
