Should be C026A

A2WD010Z - 2006 AUDM TBSTI Liberty EJ20X

<table name="Wastegate Solenoid Pulse Frequency" address="614f6"/>

Should be the same '15.27Hz' as: A2WD001T, A2WD002T, A2WD010T and A2WD012T

Installed a Perrin EBCS Pro bullet valve and have been playing around with it on Carberry. Started at 20Hz and I'm still getting flutter. Was hoping this would get rid of it. Don't think I can go much lower on the frequency either as I'm already in the <10% zone for WGDC and it's getting hard to tune.

Here's my WGDC. Makes 20psi on E85.


I found this table for WGDC under the alcohol injection tab:


I need to play around with turbo dynamics a bit because it's behaving very strange. Sometimes it will hit 15 psi (wastegate pressure) and not go any higher. Then I'll do a pull again and it will hit 20psi. Then sometimes above 6k RPM boost will start oscillating between 18-22 psi.

Proportional:

Integral:

I finally got around to tuning the external wastegate flutter I have grown to hate and decided to go with the restrictor style setup some people have tried here.

Currently running a Grimmspeed EBCS @ 18hz on carberry. I added a 1.2mm restrictor on port 1 which routes to my turbo intake.

Tried this out for the first time today and the flutter greatly reduced, barely noticeable. And nothing like the regular External wastegate flutter that sound like something isn't working correctly. I may have to play with the EBCS Frequency and possibly move to a bullet style valve as other have also done.

I literally have 1 drive on this new setup, but I did notice the boost was much more solid compared to just the 3 port EBCS without a restrictor. Typically it boost oscillated 1-2psi at WOT. With the restrictor pill, the graph lines in MegaLogViewer was ince and smooth with NO smoothing factor!

Ill add log data and RR tables later on, for reference.


@Fino, I understand adding wgdc is what you would like to do using the Perrin EBCS, but from what I've read on the forums, 16bit ECU's can only handle 20hz max. Above 18hz things start to get funky. So for us using carberry we are limited and may not be able to use the full operating frequency range of the perrin pro or other bullet style valves.

trezor has stated he has good results at 15hz and a 1.2mm restrictor on the vent port. This was from a post on this thread dated Fri Oct 05, 2018 1:57 am. This is what I'm trying out first before going with a bullet type valve.

terrjyr also has posted good results but with a custom bullet valve at 20hz.

Can i have the watstegate frequency hz address for AE5Q100V, please?
Thanks a bunch!

Edit: I emailed Oren and got the answers directly. Oren is awesome and responded in less than half a day! Much appreciated.
