What are you guys doing for the oygen sensor setup? I'm contemplating a few things here.. I do have the AEM UEGO gauge type wideband, that does output a 0-5v signal. The only thing is that my wideband sensor is located approx right behind the testpipe. This distance from the actual outlet of the turbo concerns me, since the gauge will basically have a "delay" in it's readings, which may make for tuning concerns..or not..I never really worried about it before, since it was mostly a quick reference gague, not somethig that is actually correcting the A/F of the motor. I can move it to the stock location, but that will require me to rip the whole damn wiring harness out and I really dont want to do that.. If I decide to use my stock O2 sensor, can i leave this disconnected from the ECU when i'm still running ignition off of the stock ECU? Or will that mess up my ignitioun advance map for having a dead o2? I'm still planning on running the stock ignition until i have the fuel nicely tuned.. If I use the stock sensor, I dont want to just tap off it either while it's still connected to the stock ECU...dont want the sensor cycling all the time like it does stock.. Thoughts? Or am I just be anal about my wideband placement haha :)
