Still no 02 sensors???

No even when I plugged some in it didn’t read, so am about to do a 0411 swap and put some in it.

Fix the problem before you make it much worse with a computer swap.

the computer is programed not read them. so when i do the computer swap. it will be able to read it.

The computer isn't the problem (I hope.)

The issue is that you'll be screwing with the wire harness, playing pin-the-tail-on-the-molded-plastic-connector.

So if the O2 sensors don't work now, and then you dick with everything, and the O2 sensors don't work afterward, you won't know if you pinned the harness correctly, or if the harness is somehow damaged. You'll be chasing your tail trying to figure out what is wrong.

FIX IT before you swap computers so that you know it works before you complicate the situation.

How can I fix it. The black box has been tuned to read o2 at the perfect abt with out it having any o2 sensors. I even plugged some in and it didn’t even try ro read them.

long story short.its the computer. There is no way thats its the wireing. I plugged new o2's in and the readings never changed. So unless theres a saftey back up reading prgramed in the black box. Then the guy before me had it programed. I do know it was programed idk for what but he did say he got it tune.

OK, that's not what I was expecting. I was wrong.

Yeah, you need an expert to sort-out your existing computer, or a different computer.
