Does anyone know if the Greddy ProfecB SpecII controller will control two wastegates at the same time?

TIA,

Yes, all you need to do is T them off.

 

Thanks, i was wondering if that would work

 

I have had trouble getting it to work with two gates. I run lines off the top of the gate and t them togater into the control valve. Does not seem to do anything, I am only getting wastegate spring (10 # ) of boost. That is how the directions show to run it. Should I really be running the control inline with the signel (side of waste gate)?

 

I currently have mine setup this way:

It seems to hold boost OK, but I have had issues setting the boost up. Last year, I had 2 .6 BAR springs in (8.7 psi) and I could not get it to go above 13.5 psi. I never tried disconnected a wastegate to see if that would make a difference.

EDIT - I run twin wastegates on the crossover. Only place to put them on a PTK kit

yep, that is how I have them run, Seems like the gate now has pressure at the top of the diaphram and the bottom of the diaphram. the boost control solinode valve then just controls the pressure entering the top. That is why I liked the profecb as you can close the gate (no cracking) for quicker spool up. I chose a larger A/R for this reason, but I cant get the damn thing to work. I am going to check all my vacuum lines again, I hope that distance does not matter as one gate is much closer to the control than the other.
