Hi, can you measure the resistance on this valve? (dierburg oermany)

Amazing! How is the operation? Does it feel like the stock bypass valve when you drive? Is the boost returning enough between shifts? My new genuine valve arrived a few days ago, broken. That's two mail-order valve problems in a row  New one's in the mail. Hopefully in a large, bubble-wrapped package. Wicked to see this on the car. Can't wait to see logs! Good work! |

we checked dv before assembling - piston moves when b_ldsuad & b_ldsuas =1 so we simply plug it and goes for a drive but only for 15 mins preferably at snowy roads  and because its a friend`s car a icant say anything about feelings. it produces nice sound btw |

I need to get on this done... Just wanted to mention that b_ldsuas (opening of dv under cruise) is only set when pressure ratio is less than SVDLDUVS. In many of the 1.8T files SVDLDUVS = 0s so the condition can not be set. In the 225 TT file SVDLDUVS =1s and in FR the max is 1.3. In the 518AK 003 Bin I believe i found the 16x1 SVDLDUVS map. location: 27E81 factor 0.015625 axis: 27E71 factor 40.0 (RPM) |

fukenbroken is this a genuine vag alloy adapter? Here is a "hack" for better flow.  |

I have jumped aboard too  Mostly interested in activating under cruise to improve economy! |

Very cool, a video and logs would be great! |

Some part I translated from the FR:
An approximate pressure ratio will be calculated from the division of pvdks through pu.
If the actual pressure ratio is below a certain maximum value (table SVDLDUVS), the bypass valve (n249) will be activated.
When the actual desired pressure plsol rises above the ambiant pressure (pu) + LDUVRS + HSLDSUA (for example when you press the throttle), the bypass valve will be instantaniously deactivated.
The maximum value in my mapping for svdlduvs is 3.9844. It is currently set to:
rpm 0 - 640 - 1280 - 1920 - 2560 - 3200 - 3840 - 4480 - 5120 -->
1,1094 - 1,1406 - 1,1875 - 1,2500 - 1,2969 - 1,3281 - 1,3438 - 1,3594 - 1,3750
There is another map, GWPLDU, which states the decrease in pedal % that will activate the n249, in my mapping it is set to -6.64%. I presume one could adjust this to get a more "raw" DV actuation if the smoothness of the n249 is not wished.

Hi, can you measure the resistance on this valve? (dierburg oermany)
I have measured my OEM unit (06F 145 710 G) and it is 14.5ohms |

Are you sure about your location of SVDLDUVS? It doesn't look correct it should be 16x1, see attached tt225 SVDLDUVS. There is another map, GWPLDU, which states the decrease in pedal % that will activate the n249, in my mapping it is set to -6.64%. I presume one could adjust this to get a more "raw" DV actuation if the smoothness of the n249 is not wished.
Thanks for this, I think I located it on 518AK 003 @ 11921 factor of 0.3906 with a value of -1.953 (this is the same value as 06AHS file). |

I use the 225 APX file (512kb) with a damos pack. I just cut out the values beyond 5120 rpm because they where all 1,3750, hence the arrow -> sorry to confuse anybody. I will check it to be sure, there are some errors in the damos sometimes. Maybe wrong factor. ** my RPM axis is generated from 1,2,3 with factor 640, I will reference it with the BAM file to get the right axis in there... That looks better: |
