Question about 4S Tuner


Timothy East
 

I built the tuner and cannot seem to get any response out of it.
I never experience the response shown on various videos.
There doesn’t seem to be any position on central knob with louder audio.
Examination of the build does not reveal any obvious issues. Does anyone have any suggestions?
It’s too bad really as the build turned out with a handsome unit I’d like to use with my BJ.
