EDC16 U34 MAX BOOST RECORDING WITH VCDS HELP

[vwstuff]

I notice with vcds I record a max boost at 3060 Mbar is that do to VCDS limits or soft limits ?
In soft max boost is set at 3175 Mbar

[DiegoStud]

NormVals- change from 120 to 140 and also Sig_pDIAScale_C from 0.0833 to 0.0714. Good for up to 3570mbar.

MORE BOOST!!!

Yes boost addict :) Thanks a lot Diego !

[vwstuff]

I also looking for the 2 address of Sig_pDIAScale_C and NormVals- for the map sensor ....

there's a great topic by PRJ about it here - https://www.ecuconnections.com/forum/viewtopic.php?f=2&t=28762&p=140716&hilit=diagnostic+limit#p140716

Thanks Jurebv !

If i'm not wrong UACC_ESBFormular_C is 25 --> 18 --> 0.04*a*b so max boost is only 1224 mbar ??? :giveup:
Someone can point me in the right direction ?!

[DiegoStud]

If you were still using formula 18 you'd be stuck at 2601mbar. On the other hand, formula 8 being 0.01*a*b with b at 120 has an upper limit of 3060.
What I have told you involves modifying values you have already previously changed.

[vwstuff]

Thanks Diego it's more clear to me now.
I'm still using formula 18 and be stuck at 2601mbar according to vcds logs.
Therefore, I just need to change a value from 120 to 140 and Sig_pDIAScale_C factor from 0.0833 to 0.0714 ( Merci Diego ).
So I'm "just" looking for the address of Sig_pDIAScale_C for the map sensor any help is welcome :encouragement:

[vwstuff]

No help ?
I'm stuck with my German Damos !!

[DiegoStud]

1C1286-Sig_pDIAScale_C. Find it, and for that matter any other values nearby you have currently changed to 833, change them to 714- simples.

I'm still using formula 18
No you're not, look at your other bank of UACC_ESBFormular_C.

[vwstuff]

Np prob with my UACC_ESBFormular_C but I'm looking for Sig_pDIAScale_C for my map sensor

[vwstuff]

Diego I'm still stuck ...

[vwstuff]

No one can help me ? :fatigue:

[DiegoStud]

I've already given it to you here in post #11 but I'll post again if needed:
1C1286- Skalierung Umrechung SG->Diagnoseschnittstelle für Druck- Sig_pDIAScale_C

For the record the other related values you changed nearby are:
1C127E- Skalierung Umrechung SG->DSM für Druck- Sig_pDSMScale_C
1C1418- Skalierung fuer ASMOD Druck Umrechung SG -> DSM- Sig_pASMODDSMScale_C
1C1420- Skalierung fuer ASMOD Druck Umrechung SG -> DIA- Sig_pASMODDIAScale_C

Factor for all is 0.0001.

[vwstuff]

Sorry, I apologize now I remember..

[vwstuff]

Work fine thanks diego.
Of course i'm in over boost : 3300 mbar my bad :confusion:
What is the max boost for a 1756 vk 3100 mbar ?

[vwstuff]

I notice for specified boost some deviation. I changed only UACC_ESBNormVal from 120 to 140 fpr 25 and 26
I wonder if Sig_pDIAScale_C factor is the same for both actual and specified boost values ?

[vwstuff]

I corrected all factors below : from 0.00983 to 0.0714 and a value from 120 to 140 .
Requested boost value seen to be more corect now ?!

1C127E- Skalierung Umrechung SG->DSM für Druck- Sig_pDSMScale_C
1C1418- Skalierung fuer ASMOD Druck Umrechung SG -> DSM- Sig_pASMODDSMScale_C
1C1420- Skalierung fuer ASMOD Druck Umrechung SG -> DIA- Sig_pASMODDIAScale_C

Otherwise, I'm NOT able to archive a smooth boost curve and wonder how to process :


Rescaling main N75 maps IQ axys for more fine tuning ?
Or dealing with PID controler ?

[vwstuff]

I'm still not able to figure out the Requested boost value on vcds .
I wonder where is located Sig_pDSMScale_C for this messuring block ? !
And my boost is it not steady...:afraid:

[vwstuff]

Diego I'm In the dark

[vwstuff]

My "requested boost" value is still wrong, I hope the "actual" value is accurate otherwise my turbo will blow rapidly ....
I'm reaching pd 130 injectors limits and think about bigger items .
Any advices are welcome.
Diego please don't be shy, I try to do my best based on your advices but as you know i'm slow :beguiled:
All of your posts help me a lot !!
