This is about boost control as I see it so the BEF should not influence that. 4-5 pulls in one log is needed to se if boost start oscillating like the picture above.

Any time you're looking at boost vs. target you need to also be looking at WGDC and FF.

Here the same log with FF and WGDC. I sent the log on email also.

For tuning on PWG systems you can control the pid gain, which is P I and D factors scaled together, the FF, and the target itself. Often a lower PID gain improves oscillations

I emailed you logs with both PID 25 and PID 10. The PID 10 is not much better. Maybe I went too low and PID 15 is the sweet spot. Guess I'll be back on the street testing again...

It's one of those things you'd have to dial in. At some point we'll expose the full P, I, and D functions in the tuning interface so you can better dial it in.

Both you and Steve talk about matching FF and WGDC, but I would be inducing overboost by forcing up FF here wouldn't I?

just did the diod thing and updated to the ISO firmware
attached 2 logs with map 1 and 3
fuel used is RON95 (91 octane) and running single nozzle CM10 with 100% meth
is there anything thati can change or do to make the car better?

FF is just the prediction of the ultimate WGDC output. Closer is better but I don't think it's an issue here. It seems like spool up mode (where WGDC is sitting at 100% as turbo spools) is cutting out a bit too soon causing the initial dip.

I tightened up spool mode for 3.5bar sensor maps on this test. See if its better or worse. If there is something there, I'll make it user adjustable like we have for the JB4 N54 single turbo firmware.

First thing, when cutting the diode should cut it from both sides and remove it or its ok to cut one side and leave it?!

The second question is why is the lp_fp and water temp became 0 and there not showing any thing after cutting the diode?!

Terry

It was only running PID=10 that initial spool was not enough. PID=25 spool looks ok I think.
As said, I dont care much about a bit of tip in overboost as throttle takes care of that. It is the dip after wards that can sometimes be felt as loss of power.

Everything thing else is working perfectly and showing all the readings once i start the engine

ISO_9:

1) Redesigned logging engine for much faster sampling of all CANbus channels. Normal speed logging is around 10hz for all CANbus channels now, and slow speed logging remains an option for cars with older software and drops sampling down to around 6hz.

Oh wau - this is great! Which FW revison has 9 been build on - 8_T3? I'll test flash only 100-200 in about 3 hours. Will try this out then

Terry, does this new firmware mean the slower CANbus guys may have better luck with Map 5 adapting? Right now I don't use map 5 because, as you've discussed with me, a possibility is the speed is too slow for the JB4 to adapt properly. Thank you

Hi Terry

Im new to n54tech. I have a f30 n55 335i, bms intake,******* ** and jb4. Im running pump 95 octane down in South Africa. I did the upgrade to iso 9. There seems to be heavy knocking. I cant even log the car. The car idles at 4-5psi, ecu boost is starting at 22-25 psi when i try and log. When i go back to iso 8. The number look normal again. Idle at 0psi,14 afr. Im using all default settings as on page 1. Has anyone else had this problem. Should i just stick to iso7.12 or 8. Thanks.

Yes. Cut one side. The numbers all just seemed to spike. Even afr was getting over 20. Back to 17/3 now and all seems good again. Logs looking smooth and numbers holding good.
