Ok line up your "Told ya so's."
2800$ (AFTER warranty) in work, still overboosting and not safe to drive hard.
--replaced 2 of these : EB-3-BAR-MAP-AA5Z-9F479-B
--replaced these supposedly
http://www.rockauto.com/en/moreinfo.php?pk=2956263&cc=144505 when we did the next part below
--replaced this "OEM BL3Z-9K378-A Turbocharger Bypass Solenoid
--replaced all the connected hoses to the above, i inspected and they looked new at least on top.
--replaced both turbos
--still overboosts hard, and then chokes the timing and all but backfires.
good news.
--well the front turbo was cooked. the turbine had cracks and was a very dark color to the turbine metal. so it was well on its way to grenade land.
--the control arm was so badly rusted, they could not get it loose had to replace the whole unit. how is that good news? .. well it sounds like a fail waiting to happen..
--1500$ of it was covered by warranty
I am out of ideas. all i can determine in my VASTLY undertrained skills is this ::
-The waste gate is not opening on one of the snails or both.
-the waste gate is pressure operated, so the connecting hose is bad? i do not think so its brand new.
-that leads back to the Turbocharger Bypass Solenoid switch, which we have replaced.. any one have a diagram of what goes in and what goes out ? there is a electrical lead, how do i verify IT is working or has the correct voltage? all i can do is trace back from there.
which being me is tough as i am pretty electrical illiterate.
laptop is dead so i cannot scan for pids. i have no idea id there are pids for the wastegates other than the duty cycle which if i recall us "assumed" since there are no electrical leads to the wastegates.
ideas... im about to give up, put it to stock and sell it in 9 months..
crazy bummed
FYI if your new and don't want to read the whole thread : went racing,
had the best runs ever, next morning it was ''backfiring'' at 5000+ rpm and practically stalling the car. logged it .. turned out the back firing and massive surging was the spark going from 26-28' to 0 instantly and over and over above 5000 rpm. APJ saw i was overboosting by 4 pounds. just under the ETC code limit.
edit : 928pm
idea..
Should i be able to safely test the two vacuum leading from the plastic ends (pic link below) going to the wastegates by gently sucking on them? that negative pressure should stay and remain static yes? if so then my issue is either the hot plug, or the vacuum source on the left (the metal side)..is the vacuum source static? does it vary?
