hooking up tial 38mm

[99redgst]

I did a search but could not find the complete answer to my question. I am using a profec B boost controller, how do I hook up the vacuum lines? I know you have the vac/boost source that plugs into the controler valve. Then the other line from there goes to top of the wastegate? I think thats right, but what does the side nipple get hooked up to. According to the diagram in the profec B both nipples on the wastegate get used but it does not say where the side one goes to. I hope you can understand what I'm asking. Any help would be very helpful.

Can you post a link to the diagram? I can then help you figure it out. I have a tial 38mm but I'm using an hks controller so my diagram and yours are a little different.

I'm having a problem getting a link, my computer is having some major issues. But from what I read on other threads when I did a search is that the hks and greddy hook up exactly the same. Do you have a line to the nipple on the side? Where does it go? Does it just need a vac/boost source? I'll countine to try and get that diagram. You can veiw the entire manual for greddys home page with adobe reader if that helps. Thanks for any help given.

I have this exact setup as well, hook the top nipple thingy on the wastegate straight up to the "COM" port on the stepper motor

Hook the side port on the wastegate up to the "NC" port on the stepper motor, but you also need to have a barbed "T" in the line that goes to a vac line. I have a 14b and j-pipe that I put a fitting on, so I just used this.

the second line to the "NC" port goes as follows...

[stepper motor]-------T----------[side port on wastegate]
l
l
l
[boost source from 14b j-pipe]

Hope this helps

edit: damn, the thing didn't like the way i drew that...just put a bunch of spaces where those "l's" are, the boost source taps in in the middle of the line from the stepper motor to the wastegate.

LMK if this is what you were looking for. This works like a charm for me

That seems to make sense. I'll give it a try, thanks for the help.
