does anyone know how to check a apexi safc to see if its good or bad?

Yeah, i'm interested too. My safc lights Up (the background and the buttons.) But there is no text. WHen i turn it on APEXI SAFC doesn't come on the screen. Just blank.

thats probably a bad start! all of my screens work and the unit worked perfect in my 88 supra turbo. i am now trying to get it to work with my 83 supra. it is hooked up right i think. but the damn car will idle up and down a few times and die!

i need to know how to check the output of the the afm wire (the air flow meter output) which is what the thing is adjusting in the first place. when i unplug the afm wires and remove the afc it runs good. when its hooked up it does the funky idle thing. i am stumped.
