hi guys,
wondering if anyone can help trouble shoot this problem I been having.


First off, I have a Greddy profec electronic boost controller. Havent had any issues using it. Last week when I turned the evox on, the boost controller did not turn on (black screen). I thought a wiring might be loose but two days after it turned on just fine with no issues.


The next day it did not turn on. Not sure what to do as it turns off and turned on.


any advise would be great where to start. I have not checked anything

 

Well, it's either a wiring issue or a defective unit. How did you wire in the power? Fuse taps? Wire splices? Butt connectors?

 

OP here's some advice: ditch that piece of sh*t boost controller and get a Grimmspeed or Cobb 3 port boost controller

 

honeslty I really like that advice. I've had a grimspeed on my sti with no problems before.

and whenever I wash the car, the profec starts to go crazy like it got water on it.

 

I bought the evo with it already installed. I'll check it out this Tuesday to see if there is any loose wiring
