Yeah, I'm always connected when changing values there. Just PID gain shows 0 in all maps, and I think 0 means 50.
But why the jump in 4th gear when going easy on the pedal. I did the last log just to see the boost in that moment. Seems thats the line where jb4 try to drop boost but as I'm not going hard throttle it jumps.

Do not change PID gain...and definitely don't set it to 50. You may be thinking of Duty Bias.

Try lowering DWP to 60 and see if that improves anything.

It's the Default Wastegate Position.

I have been nothing that ff value has gone up to 136. Why is that? Still on Map5 on e30. I know the max is 150. Should I lower it or leave it along. When will stop raising.
Also, can I raise duty bias to 65 on all gear? Now is 0 = 50 right?

Hi Steve,
Can someone take a look to this log I did from 4th to 7th on WOT.
If I test map7 with e40 will I hit around 17psi on the midrages rpms. I will do pure stage1 in 4 or 5 months to hold more psi on those high rpm on my PWG.

Your PWM is completely maxed out. Adding more octane (e85) won't help with that.

Yes, don't know why the pwm went that high on that wot. I did some wot before that and pwm was fine. So what it could be and how to fix it if is not a boost leak?.
Why can the pwg go crazy from one wot to another?

Steve, here is one mild log I could do this morning after the one from yesterday to check how pwm is working. Seems that from 2800rpm to around 4500rpm the boost is actually some time higher than target, so pwm is low, but after 4500rpm boost is drooping because the small turbo we know that can keep higher boost at highers rpms and boost target still higher and of course the turbo can't provide that boost, there why PWM is going max trying to meet target boost. Am I correct with this or wrong? What can be done.
Also notice that my ff value still going up. Is 145 out off 150 max. Is this a concern or not?
What about setting Duty Bias to 65 from 4k to 6krpm? Now is 0 meaning 50 right?
Secound log PWM2 I set back ff to 100. Dont know why PWM still going high after 4500rpm.

For a stock turbo it pretty close to normal, maybe a small boost leak but mostly just the stock turbo being maxed out.

Hi Steve,
I checked all connection again and I didn't see anything lose. CP top, Cp middle robber clamps and Cp to IC.
I also changed to map2 and filled up with just 93. Here are some logs I did on a highway. I can see now my trim a bit high, could it be cuz I went done to 93 octane?

Looks pretty good. You are right, trims are a bit high for 93. Maybe long term trims are low and haven't adapted yet? Hard to say since we can't see them.

Hi Steve,
Here is another one and seems that trim is getting down as it could be adapting to 93. and pwm seems normal.
Now, still bother me how I'm always 2ps1 under target after 3500rpm. On map2 from 14 I get like 12, on map5 from 17 I get like 15. If you take a look carefully on on the last of off the 3 from the last one. I did it on 6th gear to get a long log from the 2500 to 3500 rpms and boost and target were pretty much even. I have seem some other memebr with the same pwg car and mods and it doesn't drop that much on the midrages rpms. Could it be over kill IC and not getting enough of pressure or is really small leak. I don't understand this: If there is a boost leak, wouldn't be under target all the time in all rpms?
Also why it could be that map5 got a little crazy on pwm and now is back on track?
I'm filling up again this weekend with 4 gallons of E to get e35 and try map5 and 7.
Thanks for the help, I really appreciated.

ECU boost is pretty close to DME but may see improvement if you do a little DB tuning.

OK. Will try that. Now i have 0, on all rpms, so should I increase by 5,10 or 15 on the rpms I have more problem or all off them.
Also I know 0=50, but which one should I use, 15 or 65 if I increase by 15

Exactly what i was wondering. Start with 5 or 55? Do i need to reset ff to default before starting db changes?

A setting of zero defeats DB tuning.

A setting of 50 is neutral, <50 is a negative bias and and >50 is a positive bias.

Good Morning Steve,
You were right checking again and reading on a comment you did on another member, I didn't know about the damn O-Rings inside the OEM CP. You didn't ask me if i transferred them Well I just put both on it yesterday morning and here are the 2 logs I have done after the fix so far. Now I can hold good boost on higher rpm after 4k, but from 3500 to 4000rpm seems to drop a bit and go up again after 4000. IS that normal? Map2. Thanks

LOL...good find. Hard for me to think of every scenerio.

A tad bit of overboost at tip in is causing it to underboost when it recovers. It may learn a bit more or some DB tuning may be needed. It's not bad either way though.

Cool, I changed to map5 now, will give it some days to learn. Just one question about db tuning. If I want to increase it, I will need to start from 60 to be +10 right? Thanks

Yes, to increase the buty bias offset by 10, you will enter a value of 60.
