S4t2 possible safc short won't rev when hits boost

I screwed up and was adjusting my radio wiring while the car was running and the car died. Figured I may have shorted the safc.

Car will free rev as long as not hitting boost. Once boost kicks on, safc reads 0 volts on primaries and secondaries.

Going to uninstall safc tomorrow morning and see if the problem persists. With that said I just want to know other components that may be affecting this, boost pressure sensor, maf?

Will check to see if primaries kick on while free reving tonight based on safc readings.

What does the output on the safc meter screen mean? It reads 0v when it cuts fuel.

Have tried resetting safc as I've had similar problem before. Time for standalone?

Edit: I got about 2 pounds of boost with it. Running hybrid turbo with electronic boost controller and safc neo

How did you fix it? i am currently new to the safc thing, just purchased a 10th ae with safc ready. car lost power after 3500 rmp, althou boost continues starting from 3000, first thought was secondary injector not kicking in.
what does initialize mean? ecu back to the factory status?
i am goin to read the manual and hopefully i will get a hang of it.
