I just recently put a 6.0L truck engine in my 89 Camaro RS. I'm running a MP T-76 turbo so I have 60lbs injectors installed. I bought a 02 Camaro harness & computer from somebody on this board.

When I first tried to start it fired right up. I believe the problem I'm having now is the injectors are spraying too much fuel for the way it is tuned. I pulled a few plugs and they very wet and the car wont start.

My question will the O2 sensors eventually do enough to scale the fuel back or will I need to get the computer tuned first?

 

Get it tuned or put some stock injectors in till you get it there.

 

I was thinking the same thing but wanted to check first to be sure. My guess is the PCM may be setup for open loop. I'm just getting to this point so my knowledge level is almost zero. I will keep studying.

 

If you keep trying to crank it on the OEM calibration with larger-than-stock injectors you are gonna wash the cylinders and believe me it won't take long. Don't even TRY to start it again on the stock tune.

 

What Frost said.... And, change the oil/filter B4 you start it again.
