heres my vacuum line going to my bov:


you asked me before where i tapped my vacuum lines and thats where i T'd it at. if you look at the 2nd pix you can see the U part on my im. i couldnt find another pix of my 3rd T'd connection but i connected it to the boost gauge (sending unit) which connects another line behind my boost gauge. (electrical boost gauge btw).

excuse my wiring on the IM...haha i hid those wires already.

 

Did you also plug the vacuum line up after disconnecting it? By leaving the vacuum line not plugged you create a leak in the system. Also, what is your car idling at? Is your throttle body open a bit or is it completely closed? If the throttle cable is too tight then it might be pulling the throttle butterfly open a tiny bit.

 

lancer2show: thanks

senate6268: Yes I did plug the vacuum line. It's idling at 1500rpm. I didn't fix the emanage because it was too much of a rain.

I have been told that if my idle is high then vacuum won't be accurate. My tb is fine.

 

That is correct. Vacuum is only achieved when the throttle is at zero. When I start my car up every morning it begins idling at 1500rpm until the engine warms up and slowly settles down to 800rpm. But even when its idling at 1500rpm the vacuum is still -20. The issue could potentially be with the eManage and not having the throttle set yet in the software. You have alot of little things left to fix on your setup before you can begin troubleshooting potential problems.

 

My first thing is to fix my throttle and recirc. the bov. If everything will be fine after this, dyno Saturday!!!

 

hmm you know i was reading some stuff in the evo advanced turbo and engin section and it appears if your bov valve is too stiff it may not vent properly thereby leaving some pressure in the intake trackt. there would be 2 things that would happen

1) a wave that would cause your copressor to slow down (not compressor surge though you are more than likly not gonna surge)
2) force some air through the throttle body (there are holes or partial plate openign for idle)

even at idle the turbo is still making boost which usually gets vented or recirculated, so if your bov valve is not tuned properly it may be forcing it through the throttlebody since the pressure isnt enough to slwo the compressor at low boost, this would in turn cause a high idle just like a bad adjustment of the TB would since there is more air going though.

i jsut discovered thsi in the course of some reasearch and i was reading your thread so i thought this may help, i am in no means an expert or even own a turbo lancer for the fact. but it may be worth your time to tune your bov valve there are some good threads on what to tune for and how to tune in evo advanced

Ok, I have recirc. my bov.

When I'm at idle, if I hit gas till like 4k, I here that whistle noise.

I heard the same sound when I was driving the car from the shop. (it was vented)I would hit the gas till like 3000rpm. It would make that sound before I even let go the gas.

Does this happen to you guys too?

 

is like pshhhhhhh sound. its prolly your turbo spooling...hahahaha. if not i can only think of is your bov when you let out the gas.

 

It's while I'm in throttle. It's not pshhhh, it's more like loud whining soud. Today I try to locate the spot. I think it's my bov.
