correct. you can actually completely remove that solenoid valve if you would like to.

 

thank you very much, you guys are frikken awesome I will hopefully be done with this project by tomorrow evening!

 

Yes, Nipple under the UIM behind the TB to the BOV... But I have a check valve in my line from the UIM to the BOV.... it came with my HKS SSQV.

Attached is a pic of where to hook ur Wasegate actuator signal to. You will have to add this nipple on your own as the kit doesn't come with it. Read MM's greddy turbo fixes thread

 

That's not a check valve... it's a small filter.

 

Oh really? I guess I don't have a check valve....

 

fortunately, this nipple was already on the pipe

 

would there be any downsides to BOV performance if I were to tap the boost gauge hose to the hose used for the BOV? as I stated earlier, I currently have my BOV signal coming from that nipple under the UIM post throttle body

 

they 'should' be of the same source. where is your boost gauge hooked up to right now.

 

i have no gauges hooked up right now, but the car isn't driveable because of a f**ked up clutch slave hardline so i figured i'd put on the finishing touches before I take it for a spin. do you recommend anywhere to tap in particular?

 

Tee off the nipple behind the Throttle body for both the boost gauge and BOV

 

will do, thank you!

 

Never mix signals on a single nipple if you can help it, especially the boost controller and the BOV.
The gauge and the BOV should be on separate nipples.

 

Definitely does not hurt to have everything running directly off of the UIM itself. I can see the benefits of that (and now you're making me think about it with my UIM, lol). There are only 3 nipples on the stock UIM (Evap, VFAD, Vacuum Canister), so in those cases there isn't really an option to not mix signals.

 

You can also use the LIM nipples as well.

 

Those have proven to be inconsistent for signals (boost controller/boost gauge/bov), but if one chooses to move the vacuum chamber supply line (and possibly the evap, since it's only there to detect vacuum) there, that's fine.

 

Guage up top (evap) and BOV below on Vfad - nothing wrong with that .

The BOV is the only thing that needs a quick pressure decay to operate properly so that is the one I would try keep on its own connection.

 

The tiny line running from my BOV line to the Boost gauge has little to no effect on the response of my BOV. I could imagine if the boost gauge line was larger diameter it would have more effect but from my personal experience it operates fine and theoretically should have no effect on it as they are not flow lines they are just pressure signals. Just make the line to your gauge and BOV as short as possible.

Once my EBC is connected to the turbo outlet and the built in boost gauge on it is connected pre-TB I'll be able to compare the two readings though.

 

where, on the UIM might I find the EVAP hose?

 

It is the "U"-shaped hose on the top.

 

^^cool, thank you. got the car running, unfortunately it is rather lean, it is getting pretty hot. but we got the logs and you will be seeing our submission on the next submission date, MM!

 

also, MM we got a 25 sec run at 4200 rpm (miscounted), I understand that you ask for 30 seconds in your logging procedure instructions, but if i were to submit our current log, would it suffice? the reason why i'm hesitant to re-log is because of how lean it was, i'm afraid of doing any damage

 

How lean ? sounds like you have an issue unrelated to the tune . No point trying to tune till you get that sorted .
Lean could mean a vac leak ...

 

the AFR's were in the 18's and 19's in between 3k and 4k.

A vacuum leak most likely on the wastegate or BOV?

 

/\ could be anywhere - best thing would be to do a leak test on the system .

 

I am also going to be ordering a new pre-cat 02 sensor as i am getting a p0130 code. I ordered one for the install, but they gave me the sensor that fit INTO the cat pipe (short wires) as opposed to the one that fit into the OEM header (long wires). I'm not saying that is causing some of the issues, but i feel it is definitely something to keep an eye on
