Cool, another question that I thought I knew the answer to, should map 0 be limiting boost? I'm testing a new BEF and want to disable the JB4 for now (without unplugging everything) and it seems in map 0 I can't target above about 12psi.

If using map0 you'd have to also put the PWG conenctor (blue patch) back to stock.

Cool, so to verify, just disconnect the wastegate control from the JB4 and put the stock connector back in place. I assume it's recommended to disconnect the battery while doing this?

I think I'm having two different issues. I recently started getting the CEL: 120308 "boost pressure lower than expected" BEFORE I switched to this ISO hex. Seems that my boost is limited (3 psi is highest I think I've seen).

On the regular hex, I had to use FUA 51 to get consistent logs (2011 F10). I attempted to use FUD 128 on this ISO, but it looks like the issue may be back. I think I read someone recommend using "10" for the remapped 6cyl timing logging. (mine is at 0 currently).

Some sort of logging issue although I can't tell what from this short log.

I see WGDC is at 100% and boost is low so also some physical issue. Maybe you damaged board cutting diode? Solenoid connector loose?

I was researching last night and double checked the solenoid connectors, all snug. I just did another log run. Looks more consistent now.

Yes consistently no boost...

Do the vacuum line test.

lol Yeah, I was just hoping it'd reveal or change with this updated log. I won't have time to do the vacuum test until later in the week.

It's really easy... If that tests out OK we know its a boost leak. If that does not test out OK we know its something on the JB4 end, vacuum system, solenoid, etc. So it's an important test.

Need some help with Codes...
After cutting the diode and installing the N55_FSERIES_OBDII_ISO_7_T6.hex firmware update, I keep getting a lot of DTC codes and engine light on.
one that sticks in while trying to delete codes with the JB4 software is code 1381.
On the dash settings, no mater how many times I set it (function 4) to auto delete trouble codes, once I set it, get out of the menu, have the two blinks, and go back to the dash menu again, function 4 it is back to 0 (not clear trouble codes).
Any ideas?

Select F series to read codes, they should be 6 digits!

I performed the JB4 board mod and installed the current ISO software.
My procedure was:
Disconnect battery
Remove JB4 board and cut the diode leg
Re-install board and reconnect battery
Update firmware with current ISO software
Adjust and save PID Gain to 25, and auto shift reduction to 60 and Duty Bias as noted

Observations since Friday 9/8 installation:
1) on map 5 my car feels noticeably slower than before, my son noticed it too, unsolicited
2) I continue to have Drivetrain Malfunction: Drive Moderately. Got it again today while driving normal
3) I can't get a decent (no boost) log due to the Drivetrain Malfunction issue.

I have seen the Drivetrain Malfunction for a short period in the past and I believed it was due to the battery disconnection but I'm still getting it on the 3rd day after.

Any insight would be helpful.

Thank you!

For any fault you'd need to read it, and for any tuning issue you'd have to post a JB4 CSV log of it.

You're right, I should have already done that, my mistake there. I did just read the codes, I'll be looking at it after work. Here is what I've got:

120408 Reduced power mode
121001 TMAP sensor, short circuit to B+
104401 MAP sensor, intake pipe, electrical:short circuit to B+
108A10 charge air temp sensor, electrical: Signal implausible
108A01 MAP sensor, possible loose FlexFuel wires

I was running my TMAP sensor unplugged but plugged it in about a week before installing the ISO, I will unplug it again.
I will check all of my connections
Not sure about 108A10, I've never seen that before.

Thank you!

After installing the ISO T6 firmware yesterday and leaving the house today in the morning I got a warning on my F30 N55 335 BMW: chassi alignment/level issue or something like that... I just hit the ok bottom and off I went... Just to let you know. Never seen that!
I just upgraded to the T12 firmware but haven't driven it yet.

Any ideas?

No Fault Codes! Just this message on the iDrive system "Chassis alignment Issue (or failure cannot recall the exact message)" to take my car immediately to BMW immediately. Just pushed OK and it disappeared. Wonder if its got anything to do with the previous T7 firmware...

If there is no DME code don't see how it could be related.

so it seems some of you guys might be having the same issue as me. At WOT my car pulls like a freight train, but during mild acceleration (maybe 60-70% of the time)I can feel the boost building but then it just stops building and the torque is gone, unless I push a lot further on the pedal, almost to WOT. im on T6 or T7, cant remember.

Ill update to 12 and see what happens.
