So after having a shitty day at the track i tryed to tune my car via crome free and aem ugo. I hooked up the white output wire to pin d14 w/ is suppose to be the o2 sensor now my car wont start its like it drained my battery or something. So then i hook up my oem ecu ran the car like ---- due to the 450's and then i switched back over to my chipped ecu and ran fine i tryed to hook it up again and now its doing the same thing but now neither ecu will start the car and my battery died out again. I have obd2b convertied to obd1 i hooked up the output wire on the obd1 side b/c i read that some were im not sure what happend though. My fuses are all normal the car turns over fuel pump primes but no start up WTF did i do?

I dont know why it would act like you have a dead battery, but if you splice a wideband into d14 I think you need to disable 02

MY o2 is dissabled im thinging mabey b.c i didnt disconnect the pin completely i just tapped it. My starter is acting all fucked when i have no ecu connected the car turns over fast like it usually does

I just tapped mine with a quick tap and left my stock o2 sensor unpluged and had no problems with my uego.

Where did you get your power and ground?

power from the radio ground to my dash support
i cut the wire and just ran o2 to it everything is fine but my o2 is off a couple points w/ freelog and ecucontrol i can find the offsets
