seems a lot has been changed in that bin but i don't see anything specifically that should prevent closed loop.
take a datalog with eehack and post that

your o2 sensors are not doing well. they are both parked at 450mv from cold start.
open the graph window and select 'left oxygen sensor volts' and 'right oxygen sensor volts'.
a healthy o2 will start at high voltage (900+mv) and as the exhaust temperature rises, start to dip a bit. then the car goes into closed loop.
your o2s are never 'becoming ready'.
see attached graph
Wow didn't pay no attention to that they look like they are dead. I will have to check wiring. Maybe dead o2. That could be the reason it won't go in to close loop and are stuck at 128 BLMs ? Thanks Steveo I'll go take look and see what I find I'll let you know
it's definititely the reason, i've checked your bin over several times and every other condition in your log seems to be met.
Just checked o2 wire voltage that fine. The o2 test dead so I have to get a new set. If they were bad would it lock at 128 it should make BLMs higher or lower correct ?
your blms are intialized at (by default) 128 then they're 'trimmed' based on measurements from closed loop, so if it's not going into closed loop, it'll be locked at 128.
your ecm is smart enough to know that an o2 stuck at 450mv can't be reading correctly yet, so it's not entering closed loop. if you drove around for long enough, it would certainly set an o2 error code or something...
