does the power FC commander show anything?....You need to turn off the boost pressure sensor first or it will not prime or start the car.......if you already have done this, I would say that you may have a bad Power FC...I didnt have to change any wires as Power FC usually plug right in.......you may have find the different unit and try......
SR201 replaces WC stock ECU so as long as the stock ECU says WC.....it is the correct one......
I problem I had was the messed up wiring.........after thing got sorted out......it will start the car.......but before it get started you need to turn off the boost pressure sensor first........All the informative guidelines can be found from google which I have learned it from there.....but again, sr201 replaces WC so you are going to the right direction.......
