does anyone know if i can run a manual boost controller with my aps st or a solution to my problem cause i broke the tip of the comp...

 

I'm using a Greddy manual boost controller with the APS TT. It should work on the ST too.

 

I maybe be completely wrong here, but that is more than just a boost control issue. I am thinking that is also the map sensor allowing the unichip to see boost and used for tuning.

 

yup

 

Hmmm- makes me wonder something then: I now use the Blitz EBC, and essentially removed APS' BC, thus the plug going to said BC is just, um... laying there. Potential problem?

 

I don't know if it is a problem, but do you still have a vacuum line running to your FPR? If so, I would assume you still have a vacuum line running to the module.

 

that nipple shouldnt be used for anything other than boost reference to the boost control solenoid, you T off and then go to the fpr. if hes gonna buy an ebc, he doesnt need it, just send a line to the fpr. no biggie.

i did the same thing JoeDirt, it isnt a problem, do you still have the line going to the nipple, if you do it doesnt matter.

 

I have the plug just laying in the engine bay too. The Unichip still gets MAP from the T-fitting on the manifold. Not sure why you think the disconnected solenoid plug would be a problem.

 

Where is this T-fitting running to? I don't have the unichip on anymore, but IIRC it runs through the firewall to that module and T's off again to run to the FPR.

 

One line is running to the blowoff valve and the other line runs thru the firewall like you stated and T's off to the Unichip and FPR.

 

So you are still running a vacuum line to this module which I would think allows the unichip to see boost.

 

Yep.
