The restrictor pill is only for the factory bleeder style boost control. Definitely don't use it with any aftermarket boost controllers since it will just slow the response time

All oem vacuum lines including the restrictor pill should be removed and replaced.

I'm finally making some progress on finding the problem! I took the wastegate apart and hooked up a little air compressor I have for air brushing.

Keep in mind I have the 15.95psi spring combo installed.

1. The wastegate is definitely opening early for some reason.
2. When the compressor started to build up more air, I could hear a very small leak coming from my dump tube. I took apart the wastegate and looked for areas that the boost could be escaping down to the dump tube. The only thing I noticed was a tad bit of play in the piston. I'm guessing that is enough to keep it from opening the whole way.

Good news is that I ordered another wastegate (same model) and it will be here tomorrow. So hopefully that one doesn't have any issues.

I'm not sure if the issue of the wastegate opening early will actually be able to be fixed. I don't really mind if it opens early. It will only affect spool a tiny bit, probably not even noticeable. The only problem is that when I try to climb a hill and I need to boost a little, about 5psi, the car starts acting weird and my afr's go whacko. Pretty much the little amount of boost it's producing is just exiting the dump tube. So I either need to keep it in vacuum, or haul up the hill at 10-15 psi. (See 3rd video attached)

The Tial wastegates are designed to leak. The leak you heard is normal. This has been covered over and over again. Tial has even posted a YouTube video of it because so many people were talking about it (especially on the Honda forums).

When I first obtained my tial 38 mvs the first thing I did was to try to test it like an IWG by applying pressure to it with a MityVac in order to observe and ensure that the valve was opening as expected. It didn't. I heard pressure leaking away. Why? Because the tial EWG is not designed to hold pressure applied. It is designed to leak off that pressure through the valve stem. After simple research this all became clear.

I put the 11.60 psi spring combo in and now the car pegs at 15psi, which is great news. Only downside is that it still cracks open around 5-10psi. I don't really notice a difference in spool but I'm sure it's affecting it a little.

I'm still worried about when I climb a hill and I only want to hold the psi around 5. Basically just enough to keep a constant speed climbing the hill. But the wastegate will want to open, dumping some of that air I need to maintain psi. Any ideas?

Since you had to grind your ewg to get it to fit I'm not sure what you could do. A 3 port bcs works very well, but you would have to figure out some way to plug the extra hole you made from grinding the valve to get it to fit.

Well as an update, I am now able to control the boost. I believe I have the ~11psi spring in and when only running spring pressure, it was cutting off at 15-16psi. So I hooked my Hallman MBC back up and got the boost dialed in to 19psi, or so I thought. I did a pull yesterday and it hit 20-21 psi. So I turned the boost down a little bit and got it back to 19. Then today, when I did a pull, I was hit 17-18psi. So I turned it back up to 19. Now I just got back from a small cruise and I was hitting a little over 20. What could this be from? If I switched to a 3-port from Grimmspeed, would that help?

has there been a lot of change in ambiant air tempature where you live? even 20 degrees? I no that air temp can affect the MBC. A 3 port bcs couldent hurt....cobb or grimmspeed. the boost control of my cobb 3 port is great.

Definitely not 20 degrees of change when I did the pulls. Is there much of a difference between running the ebcs the way that Tial recommends (use top and bottom port on ewg) or doing it the way Grimmspeed recommends it (only use bottom port and leave top port open)?

In your third video, why does your EWG open at 4500 RPM on stock VF39 turbo? I expect it to open much sooner.

I know you stated you are running the 15.65 psi spring combo, but what is your desired pounds of boost? Your EWG spring combo should be half of desired boost pressure. So with a 15.65 PSI spring combo, I expect you to be looking for 30 PSI?

On my EWG, with Grimmspeed EBCS, I run the 10.5 PSI spring combo running 20 PSI on a VF43. My wastegate cracks at 2800 RPM and is fully open at 3200 RPM. Never had over boosting and have a near straight line that slightly tapers down throughout the RPM range.

My car peaks at 20 PSI.

no shouldent be.... I think the only diffrence is that instead of have the one line from the bcs that goes to the inlet pipe. u use the top port of the ewg. you could also leave that one open at the bcs. numbers 2 and 3 on the 3 port bcs are the only ones that really need to be hooked up... at least thats the way the number are on my cobb bcs. one to the nipple on the turbo and one on the EWG.

A better test would be to test the WG with it clamped on the up-pipe just like it is on the car. If that means you have to remove the up-pipe do it. It might reveal some sort of binding of the WG piston that may be the cause ot it not reaching full travel when installed. Testing it off the car may not find that. Is you fire ring warped or un even?

I was only going part throttle in that video showing how it opens. I wasn't anywhere near full throttle.

I am currently running the 11.60psi spring combo (according to Tial). Based on what my boost gauge is telling me, it is actually a 15-16psi spring combo.

In response to kellygnsd, I don't have trouble keeping my boost down anymore. My issue now is inconsistent boost. I set my manual boost controller at 19psi, than the next day it will be 1-2 psi higher or lower. So what I'm asking now is will an ebcs keep my boost more consistent?

Do you have access to a 3 port bcs you can swap out and try? Its almost sounding like the spring in ur MBC is not holding properly. I had a buddy with a boosted civic that had a problem of the vibrations in the enigine would rattle the MBC alittle. did u get it used? almost makes me want to go out and un hook my 3 port and see if I go over 11.60 because i have the same sping in.

Have you ever heard the flutter a EWG makes when paired with an EBCS? That is the Wastegate piston going up and down, opening and closing the gate. The EBCS pulses as it sends pressure to the wastegate as it trys to keep the pressure consistent. It compensates when the pressure is too high or too low, where as manual dosen't.

I bought the Hallman brand new. I don't really have access to a 3 port at the moment. I suppose I could hook the stock one back up and see if that changes anything, but I'd much rather run an aftermarket 3 port ebcs.

I am not saying you should run a hybrid set up but if you get a ecbs it could be a possable. my tune advised me aginst it as he said it can sometimes make thing more complicated then what it need to be. but any ways bunch of good info on boost control itsself

So I just got back from another cruise. From the last time I drove the car, I had the boost dialed in to 19psi. I did a few pulls and it kept telling me I was hitting a little over 20 psi, not quite 20.5. And then at one point the boost gauge told me I was hitting 24 psi. So then I was like WTF. If I were actually hitting 24 psi, then the car should be in limp mode (the initial reason why I switched to an ewg). So I hooked up my accessport and started monitoring boost through that. Accessport was telling me 18.5-18.6psi every pull, while the boost gauge was telling me 19.5-21psi. So now I came to the conclusion that my boost gauge if screwed up. I was having issues with it before to where it would be reading like 10psi more than it actually was. It'd say I was hitting 5psi while the car was idling. Then a few minutes later, it'd go back to "normal". I will be giving Prosport a call tomorrow to see what they say about the issue.

You've been using uncalibrated measuring equipment this entire time? Sadface.

Where did you get that I've been using an uncalibrated device? There is no calibration to the Prosport boost gauge (most of the time). Does an uncalibrated boost gauge randomly read that I'm hitting 5psi while idling? Or does it tell me I'm peaking 20 psi on one pull, then then next pull I'm hitting 24psi without changing a thing? It would be uncalibrated if it ALWAYS read a difference of X psi, but it has been an inconsistent difference.

You've been getting inconsistent readings this entire time from your boost gauge, which is a measuring device. I'm not sure if they come calibrated from the factory, I've never used a prosport boost gauge. My point was that you've been judging the effectiveness of your ewg setup with a boost gauge that isn't working right, and didnt mention that you were using that OR that it might be broken. If you lived close I'd have let you borrow one of the mechanical ones I have for a few hours, a known working one. It might have saved you some time, who knows. Time to troubleshoot your sender and gauge.

Back with more issues. So the weather has been a little warmer, up around 90 degrees. When I dialed in the boost (with the readings from my accessport), I had it dialed in to 19psi. That was when it was about 70 degrees out. I did a few pulls today and it's only been peaking around 14.5-15psi. My intake temp, according to the Acessport, on my last pull was 91 degrees. Is it possible the car is pulling timing due to the heat? I have a very conservative tune loaded on the car with the timing bumped back. Would the ECU still pull timing even though I already have the timing very conservative? I checked the Accessport and my Feedback Knock was at 0. I also am pretty damn sure I don't have any boost leaks. Any ideas?

If your Timing Comp (IAT) map is set to pull timing around 91* F...then yes. Regardless of how conservative your tune is. Even if this were the case...I don't believe it would cause a change in boost pressure like your describing.
