Default EBC install - length of vac line

Hi everyone

I'm about to install my PIT BCU+ EBC. Now I have a question about the vacuum line.

As the 1,6l NB has very few va ports on the intakte manifold, I have to adapt the EBC vac line on one port together with the Greddy MAP sensor and the sensor of my electronic boost gauge. And because I want to install the EBC controller on the drivers side the lentgh of the vac line will be approx. 6.5 feet (2m) long.

Is this a problem? In which order should the 3 device be tapped into that vac line?

Thanks for your help!

There should be a nipple or something on the turbo compressor houseing, use that for the wastegate source.

I just checked - at my turbo compressor housing there is just a metal "bump" where I suppose should be the vac source nipple. Other than that there is just the wastegate connection line. It's a Garrett T25.

I would guess that sharing a stock-sized vacuum port for your map sensor, boost gauge, and wastegate line is probably a bad idea. You could install some more vacuum nipples for really cheap. All you'll need is a drill bit and tap.

Thats where the EBC goes, inline the wastegate vac line.

Yeah, I know that the solenoid for the EBC goes there, I am talking about the vac. line for the controller unit of the BCU+ this one needs a map reading to be able to controll the solenoid.

^ oooooh. Yea you want that at the manifold. It should probably see both vac and boost. Length of the line wont affect it.

Thanks Sam. And the number of devices plugged into that line - any problem?

(BCU+ handbook says you could use the line to the fuel pressure regulator.) Maybe I will use that one?!)

Doesnt matter what you use as long as it has vacuum and boost signal. If its easier for you, you can always get a distribution block and get it from the brake booster.

Personally I wouldnt Tee off one line to many times, in my mind its a reliability issue. Id try to T off another if you can. The FPR signal sounds fine as well.

Just one more question about the vac lines. There is one line at the bottom of the throttle body which routes directly in the number one intake tube(runner?). Could I use this one for the BOV?

Thanks again!

You can use any port you want. If the port has a line on it now you should T off of it though.
