The same concepts apply, but not exactly. On the B58 the larger issue is the moving DME BT due to internal fuel limiters, so it's not practical to fully nail down boost targeting via duty bias tuning. Just get it in the ball park.

EWG applications are "integrated" boost control, meaning the DME is still doing the majority of the control with the JB4 only adding or subtracting from that slightly to keep boost on target. As such the logs will look nothing like the PWG ISO logs you see in the thread.

Duty bias tuning can still be done on EWG vehicles but generally only to set the proper shape of the profile. In most EWG cases the default 50 across the board settings are suggested.

Terry, my buddy has similar problem w/ spooling. What's the difference about closed and open loop? What the BEF does in this situation? Thanks.

the FF Wastegate Ad. , switched automaticly by the jb4?
Because its alway another value ... if i change to 60, it only needs 2, 3 runs and it switched to 80, 111, 113... 138 ,....

next problem, i cant choose the PWD in a LOG !!!?? ... there is no position...

only FF is available...

so i cant change the duty bias, because i cant see the reaction to it...

When we run outside the range of what can be easily fueled JB4 only then you wind up with issues like the DME going in to open loop mode at full throttle, trims maxing out, etc. The BEF rescales the DME for higher power levels and corrects the issue directly with revised fuel and fuel trim tables.

.... so again...

back from the Autobahn ....

first time 7th gear ... over 280km/h ! no problem..
i was happy that it runs fine...

back to 4th gear... full accel. .... switch to map 4 ....
i found out that always if the FF Wastegate Adaption switched over about 140, i get this problem!

So how can i fix the Value of the FF WA!?!?

Why is it always changed by the jb4 ?

here are the good run LOG
(i witched the FF WA back to 120..... and it turns aotomaticly back to about 112, 114) )

You can disable the wastegate adaption in future use D "bits". It is bit 2 which should give you a decimal vale of 66 with the bit for FF gain also disabled.

Hi Payam.

ive been reading this thread to better understand FF, and think i have a good hold on it now, so just need to test, and adjust DB accordingly while logging.

However, i noted that i had FUD on 64 (i think), and my FF was always around 82, i made FUD 0, and have noted my FF is climbing, currently on 135. i d not drive hard all the time, and generally am in traffic, or close proximity driving due to being only 7km away from the office. would this cause the FF to climb, or would this indicate an issue, possibly around the Vacuum or Boost system?

im yet to fully investigate, but i thought id be a bit premature and just ask for the meantime.

thank you in advance.

That is a good indication of a boost leak but that can just be coincidence. If you can get me a couple logs in the support section I can view and better evaluate for you

Good morning Payam

Thank you.
I will get you a log, and update my thread with the new log and explanation as to why.

Also, i always drive on Map 5. I like the auto tuning feature. is it fine to remain on Map 5?
With regards to logs, would you want a Log from Map 1, 2 and 5?

My current setup is:
JB4 + MHD Pump BEF
Upgraded Charge Pipe w/Forge DV's
Hollowed out **'s

Thanks again in advance.

Justin

Hi there.
LAST SAFETY = 2 points to AFR running lean. so it will switch to Map 4.

in User Adjustment Settings, set the 6 Cylinder Timing Logging to your relevant ECU.
eg: I8A0S = 4, IJE0S = 5

Yes, map 5 is fine for your car. What fuel are you using?
