Yup I still have the issue. Also have the issue about there are 10 menus. So when I get past menu 5 I have no idea what I am changing as it does not react on the tach gauge like explained anywhere. I was trying to change my boost limit the one day and was very confused

N55_F_PWG_INT_13:

1) Adjusted wastegate learning, FF will now remain fixed, and duty bias by RPM will automatically learn.
2) Adjusted base FF algorithm to allow a wider range of learning.

Could use some PWG integrated logs on the new firmware to ensure it's doing what we expect it to do.

Just tried it, car feels like it’s breaking up in 3rd gear, look at the WGDC oscillation. What do you suggest? It was running great before this update.

Edit: it was overboosting, lowered FF from 100 down to 60 and its learning down now. What do you suggest for FF with PWG13 firmware?

1) - Terry, this is programmed with FF Fixed, what is the default setting for FF now?

Here are a couple of logs from today, boost really drops off higher RPMs. Look at the spread between WGDC and FF in gears 4-5. Should I increase FF? Right now its at 60.

Here is 3rd - 5th gear at 65FF, what do you think?

I just posted a log run using this firmware in the support section

Sorry lost track of this thread... Log looks as expected to me. Any issues on your end?

clor · 04-06-2019, 01:21 PM

Hey Terry,

Wondering if you can take a peek at my logs. The trim is high and the AFR at the top end isn't near 11.5-12 at all.

Please see attached for changes you suggest.

1. Should I change the Duty Bias back to all "0" or "50"?
2. What do you suggest for Default Wastegate Pos and FF/Wastegate Adaptation?
3. What do you suggest for Fuel Open Loop?

Hey guys have a quick question regarding the firmware on the jb4. I have a 2013 335i pwg currently on firmware PWG_11_t1.hex. Just curious which firmware I should Be on now. Should I be on N55_F_PWG_int_12.hex
N55_F_PWG_int_12_t2.hex
N55_F_PWG_int_13_t1.hex

zole2112 · 04-26-2019, 03:32 PM

I was on ISO PWG v13, which is what you should be on. I updated my board to the v2 board and I'm off ISO now

5soko · 04-28-2019, 09:03 AM

Do us PWG guys when using absolute target Map 2 have to :
*** Be sure to set DutyBias to all 50 if set to 0, or you will under boost on absolute target maps ***

v13 is the latest PWG firmware.

Hi Terry,
Just installed my JB4! Waiting on the intake and ******* ********! Doesn’t look like I’ll be seeing them before the weekend, oh, well...
However, I’m wondering if I go with the BMS data cable, if I can skip the CAN connection without always reverting back to map 1?
I prefer to run GoPoint BT1a in the CAN outlet.

Thanks,
Bob

Is anyone else having break up issues under version 13 firmware. I had to downgrade to 12t2 to solve the issue. Validated it was version 13 by swapping back and the problem came back with the firmware.

ccochrane · 05-20-2019, 06:32 PM

I have the PWG with the cut diode setup.

Is PWG_11_T1 the latest firmware for the cut diode setup?

I haven't had any issue with 13 myself.

Creative911 · 05-23-2019, 01:15 AM

Hi Terry,

I've installed and flash with MHD last night, so I'm JB4+MHD backend flash. I would like to go into Map 6 and see what else I can bring out of the car with the current setup, what's the max boost I should run with this setup and the settings I should start with in Map 6

JB4 was firmware to N55_FSERIES_OBDII_PWG_11_T1.hex, I'm not sure if I should upgrade to firmware 13 as I see some is having issues, might go to 12.

2013 535i Mpackage 8spd
JB4_F_PWG2_RACE_5 - running this due to no pump, but I always use 93oct and would like to start using E85
******* **
straight pipe
BMS Intake

Thanks in advance

Creative911 · 05-30-2019, 12:33 PM

Did I post this ^^^^ in the wrong area, new here?

Terry @ BMS · 05-30-2019, 12:37 PM

It's fine here, add a JB4 log though for any tuning advice!

i recently upgrade to the version 13 PWG firmware too, I have the car in Map3
I feel more power
but the engine bay and hood near the charge pipe gets so freaking hot

Im going to try Map5, but does Map5 allows me to run the WMI too?

kinetic · 05-30-2019, 07:13 PM

also whats with the new Ethanol setup?

its a 2013 M135i N55 engine F Series, PWG
with wagner ******* catback
wagner intercooler
charge pipe
WMI kit
and 91 fuel with octane boost adittive (here in mexico we dont have 93 octane fuel)

Here is the log from a pull I just did, only change is that I added E85 (30%).
