Does the Civic have one? I tried looking for one from the bay and didn't see anything that would resemble one. I figure it would be a recirculating bov but I don't see any bigger hoses going into the Intake charge piping either.
+1 on the Bypass Valve (BPV) instead of Blow Off Valve. There's also a lack of any atmospheric blow off sound in these cars from everything I've heard.It likely runs a BPV. I'm willing to bet it's under the windshield right before the TB/IM.
I think you're aware that VTA is bad news on modern ECUs without a proper tune...
I'd love to try and change it out and try to see what I can do to compensate for the air that would be recirculated whether it be tuning or another option.+1 on the Bypass Valve (BPV) instead of Blow Off Valve.

You mean switch from BPV to BOV? Might throw a CEL or not run well since ECU won't provide the right amount of fuel without a tune to compensate for the altered air flow volume.I'd love to try and change it out and try to see what I can do to compensate for the air that would be recirculated whether it be tuning or another option.
Well from what I know about BPV's, they can be atmospheric as well. The bpv for the supercharger kits can be changed to VTA so I'd imagine the oem BPV could be too? I'm just not sure about how to compensate for the extra air that would have gone back into the charge piping and how the spool would be on the turbo. May be too early for the tuning on this car as well but I hope the bigger guys in the industry test the car out and provides info.You mean switch from BPV to BOV?

Not trying to mean but it definitely sounds like you have you priorities backwards. You want to fickle with unmetered air on a motor pushing 2000 PSI in fuel and 16-17 PSI in boost? Surge issues aside, I imagine you could tax the HPFP from running too rich. Direct Injection is far more unforgiving than multi-port.I'd love to try and change it out and try to see what I can do to compensate for the air that would be recirculated whether it be tuning or another option.
may be but there are many direct injected cars such as my FRS that gets boost added to it and with a little tuning or even a OFT..can run perfectly fine. Wouldn't the civic be sort of the same thing?

Not a Honda but many of the issues are shared:

for sure waiting for tests or until someone shows me it can be done. I've been in the modding game too long to just mess around hahaI will add that I'm all for tweaking things around when done responsibly. Do you have plans to monitor KR, AFR, STFT, LTFT, MAF and MAP?
EDIT: Just saw your last post. Sounds like your waiting for more data.
Correct but it had something to do with people wanting them purely for the sound. The 1000hp Gtr's and Supras have them because they have to.I know the function of a byv and bov. There are advantages to both just like how there are advantages or internal and external wastegates. From my research there may be a solution. Fast and furious didn't have anything to do with these 1000hp Gtr's and Supras having a nice sounding/performing bov..
