Dynotuning
Alright so i've been having trouble for a while now to get my 99 GT dynotuned. The tuner guy told me that the o2 sensor were "dead" i replaced all of em and even the whole engine wiring harness and still nothing-.- my question is can i use a wideband sensor to get the car tuned?

What do you mean there dead, if your conputer had no upstream o2 sensor readings it would run like *** and through a bunch of codes. The car needs upstream o2s to work as they provisw data to the ecu. A wideband sensor cannot do that

No i dont think my stang has ever been tuned, i was just trying to tune it since i had gotten the engine rebuilt and put some comp cam 270's but i showed up to get it tuned and he plugged up the tuner and everything and then told me the o2's were not working he showed me a dynotune file off another mustang on the computer how the readings suppose to be moving up and down like "mountains i guess you can say, sorry for the brainfart lol and my reading for the o2's were just flat lines _______ <---like that hopefully ya'll can understand what im trying to explain..this was my first car i've ever tried to dynotune so im new to this:/

You said you rebuilt the motor. Are you sure the harness for the O2 sensors got connected at the top front of the transmission?
