Feed Forward. It's a component of the PID boost control system used in conjunction with duty bias for the "fixed" or predicted component of the PID output to the wastegates.

Working on v9 firmware with change to the map numbering. We're going to eliminate map3 the 25psi fixed boost target, move map2 the aggressive additive map up to map3, and then add a revised map2 that better splits the gap between the general use map1 and more aggressive map2 currently in the firmware.

Also making some adjustments to the FF settings. Generally speaking we've found better performance with lower FF values allowing boost to slightly under target. So in v9 we've adjusted the defaults so that FF = 50 behaves like FF = 40 was behaving previously. As such you'll want to increase your FF back up to 40 on those maps that you lowered it on.

I have a question. Until which map on v9 is safe to go without DP? And the people using DP and JB4, are they mostly using catted DP because of the no flash?

I'm not a fan of DP for the platform and wouldn't suggest it. THe map has more to do with the octane level being used. 91, 93, 91+E85 mix, 93+E85 mix, etc.

Thanks for the answer. Which map do you recommend for MS109 fuel, Map3? I only have BMC filters on my 2019 F90 no comp.

I'd start with map3 and log it. From there probably will be OK on map4. But map3 may out perform it.

I currently have BMW F90 M5 ECU Tuning - STAGE 1 (+84HP / 120TRQ),
best 1/4 10.43
0-60 2.75
60-130 7.08
Temp 80F DA 3500
Gas 93 15 Gallons e85 5 Gallons

Mods Remus catback, secondary *******, charcoal delete and Kn&n drop in.

Now my question is will JB4 help me further combined with the tune or even by itself. I don’t know what pSI I’m set to. I have used JB4 on n54 back in the day with auto tune map 5 and loved it.

Is it going to map0 or just app showing map0 when you reconnect? Do a log next time without changing map.

Looks fine to me. I'd change duty bias to 50 across the board and give map2 a whirl. May also want to update to v10 firmware.

Default JB4 issue with bluetooth - 09-12-2020, 09:20 PM

recently got a new 2020 m5 comp. did the jb4 and cannot get the bluetooth hooked up to my phone to change maps and data log. I get a error for kit not owned. anyone had this issue and what you did to solve this issue. New to this platform. I am also running *********. what map should it be on for this. Is the map change still used with the BC on the dash to switch. I do not have the EWG sensors plugged in as well. run 93 primarily.

Is it a new or used system? If used it needs to be unlocked by following message in screen.

Start with map2. The BC map should be active but another customer mentioned he had an issue with it. So we may have broken it at some point in the recent development.

Just posted v11 firmware in the alpha channel and could use a few logs. Main change is to maps 1-3, rescaling how the additive is factored in. I'm hoping people find it smoother/better. But logs and feedback are appreciated!
