I think a flex line would good enough, I think the goodrich is a steel reinforced rubber. I still recommend that you do tests without a BOV, I think with bov blocked, the amount of air available for sas would increase.
Why don't you use manual boost control? you seem to like to do everything the hard way :]

Ok so Ive been still reasearching a lot and I have two questions that I need to find someone qualified enough to answer:
Celica GT-Four WRC models used a secondary air injection
Lancer WRC used a secondary air
Subaru Rocket secondary air, however more complicated rocket was fully stable at idle making massive turbine shaft speed.
1) Did Lancer WRC models actually function more like the Subaru Rocket system?
2) WRC 04+ lancer models used a long tube LMP-like turbo manifold, it resembles more of a rocket type system with out an englarged rocket chamber. Is there any clarificaion on the processes that Lancer WRC used to get bypass anti-lag?
It appears it was less bang bang and much more controlled combustion. Again hard facts for the EVO are hard to come by. Subaru has let the cat out of the back, specifically with www.subaruwrcspares.com or etc etc websites.

I did a test where I hooked a compressed air source up to the SAS pipework. There seemed to be a lot of restrcition when i was trying to use a blow gun to do "something". Ill have to look into something higher flow for sure. My next move is to use a TiAl wastegate on the UICP to redirect air I pretty much plan to swap that right into place for my greddy type s and use it like a blow off valve permanently.
more to come. Wedding and baby is slowing up progress but Im still tinkering.

Pretty sure my sas setup is causing surge. I need a tsss!
Donner is going to help me with a SD rom that he prepared for adm cars which has SAS code in it. Some tweaks need to be made to his rom.. I modified my SAS metric-jic adapters today more than doubling the size of the hole feeding the manifold from my pipework. Including flairing th end of the fitting to transition better to the manifold.
Ill create some new pipe work, but I want to use a wastegate because I think it will be better suited to vent the large amount of charge air from the UICP, and redirect it to the manifold. This looks like the function of one of the WRC photos. A boost accumulator would be easy to impliment so that it could provide boost pressure to the bottom of the wastegate to help hold it open. ideally the valve would be sprung soft enough to open with very little vacuum. Im still putting thoughts in

How Ive been envisioning it.
The SAS rom will provide fuel.
Negative timing is still stuck at -20.
Transient states will require additional parameters Im sure
This is a complicated version, yet flow likely improved over stock. however we still are at odds with tuning due to a lack of a MAF or shaft speed sensor
How can I hack a MAF into reading air flow while running speed density?
Probably would be easy enough to weld in a Subaru blow thru maf flange to my STM uicp and monitor flow that way... I have a subie maf already with pigtail. Might be easier than a shaft speed sensor and would measure air passing thru the system well.
Shopping list:

Donner has proviided me with a fixed 3dsd ROM that I have to test tonight. I have been copying and pasting my mostly tuned 3dsd ROM 8859 > 8858. The best thing about even looking at this ROM and tuning 3d ve is a more appropriately sized 3d VE table. Its 19,23 much better. Screen shot later if it works. I have to get a few more things copied over. Still looking for a few XML defs, IE mrfreds iscv disassembly thread, I would love those for 8858 since cold start doesnt need to be at 10000 RPM
I have reread the beginnigs of this thread and it looks like some of it makes a lot more sense now. I cannot wait to get teh few dollars I need to buy an appropriate wastegate valve and rework the piping. This rom wil solve two things: valve actuation, and the addition of fuel on overrun. However, if some guru is interested in seeing some measurable gains, I will hope that they can provide me a way to use a MAF with this rom at the very least allow it to be logged and at the very most provide some ROM editing thatworks like the flex fuel ROM and perhps allows a user definable interpolation between timing based on maf on overrun.
IE if maf is producig a lot of airflow on overrun,then interpolation would favor towardsw the side of the maps with positive timing,and if ther wasnt much air flow then the maps woul favor the alternate timng map which features more negative timing.

Is it possible to edit the AXIS of an already defined table in ECU flash and have the table working from that newly designated axis?
Say I want to take the EGR enabled advance, and use that table by changing the X axis to TPS. I edit the definition of that table along with the adress and get a table that is x y tps rpm
in the 3d part I map how much reduction I want to apply. Since that table is typially an adder/subtractor I can map it -55 if my lowest load is normally 35* advance, at closed TPS (15%). Then I take the mapping on the x axis and move it to reflect an opening throttle angle by reducing the amount of timing that is subtracted from the base timing as TPS is increased
or maybe my idea in the previous post could be implemented by timing VS maf value that would simply be a 2d table that says what value the timing would be locked at by what airflow the maf is producing. Some how you have to create a target though. and while were at it if the fueling value allowed in the SAS equipped ROM was able to be incremented or decremented that would be a perky substance

figured it out, scaled the 8859 rom as unit 8 like the 8858 and the values are identical.
sigh doesnt explain major afr difference in the two roms .. A little tuning again
Im down though, because activating the fresh air valve will be worth it.
Donner thanks thus far!
