Ok. I have an older Apexi AVC-R installed on my car. Im in the process of installing a Greddy Profec. I noticed that I had 4 wires that ran to my ecu. They are Power, IG Power, Injector singnal, and ground. These wires run to the pressure sensor.. The Profec doent have anything to attach these to. So what should I do?? I dont know if I need this pressure sensor installed and if I do I dont know how I would go about installing it.

 

Why are you stepping down?
Did the AVC-R die on you?
