I have an apexi vafc2 that i know it was working when i pulled it out of my gsr..sold the car and later sold the apexi.. the person i sold it to claims that it does not work and gave it back...i do not have a way to test this item now...and when i hook it up just to a battery the screen does not light up and the tuning knob only lights up orange...can anyone help me test this.

 

Sounds like the guy you sold it to got paid to break it for you

 

take a picture of the wire harness and post it, if you or the guy you sold it to ran any wire extension it may not function properly thats the only thing I can think of.

 

sorry i was out of town for biketober fest.. this is what the harness looks like.
