I have the APEXi auto timer, and I installed it, hooked everything up right, but my O2 isn't reading. It says that the O2 won't show up if the O2 sensor is bad. But it seems to be working just fine on the pocketlogger, it's not sluggish changhing numbers, they change quickly, and do it a lot. So I'm pretty sure my O2 sensor is fine. It also says that the disply will read "---" untill my O2 sensor warms up, but thats what mine reads all the time. Did I just get a bad auto timer?
 
You might have tapped the wrong wire on the ecu. Check the O2 Sensor voltage on the autotimer, if that is working (it should be changing quite often and drastically). Then I would say you have a bad timer, if you cant get an O2 sensor voltage reading, then double check your wiring on the ecu.
 
Well I followed the wiring diagram on the instructions that came with it. And I used the instructions for the wiring locations on my ECU, unless a 1st Gen eclipse and Talon ECU's are different? They look the same from the pics of ECU's in the instructions.

When my Auto timer is on this mode, it reads 4.34 - 4.43, and it only changes when I hammer on the throttle and start going real high in the RPM's.

But when I am in the other mode, it just reads "---" all the time.

Maybe I'm just a tard, and I did get the wrong wire. I know its the 4th wire from the right side of the ECU, and its on the top row. But there are 2 white wires right next to each other, and maybe I was being retarded and spliced the wrong white one. I guess I will have to tear it apart again and check.
 
WRONG WIRE !!!!! :mad:

I put my new Gauges in today, and one of them was a A/F ratio Gauge. Well I hooked my Auto Timer onto the same wire as the A/F ratio Gauge, and it works now.
