apexi timer install question

[Eastwood95]

OK, i've already done a damn search, so dont tell me to search. I've looked on vfaq and google and still cannot find my answer. I was using a greddy turbo timer and just got an apexi from a buddy and he didnt have the instructions. I hooked it up with my HKS wiring harness, hooked up the ground to vehicle chassis, hooked up the e-brake line(gray wire) to the e-brake, and hooked up the A/F(white wire) to pin 76 on the ECU. The timer works fine, but my o2 voltage on the timer is reading like 1.5 to 3v. It reads 3v when i'm at WOT. So my question is, do I have the A/F wire hooked up in the correct line? and/or do I need to use a ground from the ECU?

Someone with knowledge bless me please...............

Did you mess with the 02 or a/f settings on your timer. I read on the website that you can change the voltage settings on those two, but i didnt quite understand what it meant..........does anyone know? I'm stupid ok................

I just installed mine last night. It works, but I dont really know how to set the paramenters. I dont know what the numbers mean on the AF i stays at 14.5ish then goes to 10 or 20 and starts to blink.

I moved my ground to the ecu, and reconnected my o2 line cuz I had a bad connection and that fixed my 02 readings. I'm a little rich at WOT, about .93-.95 but I can live with it until I hook up my AFC...................

the settings you can mess with are just were it 'blinks'-warns you.
