WTF did i do
 

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?

Re: WTF did i do
 

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
