hope all goes well 2.0

 

Yea, hopefully. Same to you.

I just don't understand when I plugged the 2 vacuum ports, vacuum itself didn't change!?!?!?

Or should I hook up the blitz tt to different vacuum line sine fmu, fpr and blitz tt share same line? I still want to hook up a regular boost gauge.

Which line can I use?

 

I have EVERYthing hooked to my fmu line, I have an accurate boost gauge and an active fmu/DV

 

Here - do this: take the vacuum line off of your your BOV and plug the vacuum line. Go inside your car and look at your gauge. Tell me what the vacuum reads.

 

1) How many things do you have hooked up to your vacuum line?

2) What other vacuum line could I use?

3) What's you vacuum shows at idle?

 

Can you please take the vacuum line off of your BOV, plug it and check your gauge. I'm pretty sure I know where your problem lies.

 

Ok, once I get home, I'll let you know, give me 2 hours.

What do you think it is? Where is the problem? Talk to me, lol.

 

Here's the cut and dry of it. You are running a recirc valve as a BOV. The valve is opening under idle and light cruising which is allowing unmetered air to enter into your intake system. This is why your idle is high and vacuum is incorrect. If you remove the vacuum line from the top of your BOV, the valve will remain closed under the pressure of the spring and will open when boosted air forces it open for venting. BOV's that vent into the atmosphere have much stiffer springs to allow for the valve to remain closed at light acceleration and idle. Recirc valves have lighter springs that allow for partial opening.

 

Stupid me, didn't think of that. Hopefully this is it. I'll keep it posted.

High idle is bc I never set-up my idle on emanage. That will change today.

Again, thanks. Let's hope for the best.

BTW: If you have Boost gauge, boost controller, BOV connected to one line. Where did you connect your fmu or fpr? Just curious.

 

I'm not using an FMU or FPR. I'm tuning by flashing the stock ECU and running 440cc injectors. Stock FPR.

 

So everything is connected to your stock fpr?

 

I took the line between the fpr and fmu (what would be the intake mani) an just apped it a couple times. then the line hits the fmu and is also fed to the IM

 

Technically yes. The vacuum line that goes from my FPR to the intake manifold is Tee'd into for my vacuum/boost source in my added on items.

 

Bad news. I unplugged the vacuum from the bov (bov shut), but the vacuum readout shows the same. It moved .01. Disapointed.

 

okay.........im posting some pix imma try too what i can find right now
