I'm work on an 05 LLY that had a P0609 code put a new ecm in, and now it is blowing black smoke and has no power. It throughs a P0101 code and stops smoking and run fine but the EGR wont work , clear the code and it goes back to smoking and no power. I put another MAF in and the same result.

There is two programs from GM for the LLY one is for the square intake box and one for a round box. The round is like the LBZ I have never seen one on an LLY, but it has different parameters for the MAF

Gotcha. I've never seen one on an lly either. Good deal it was an easy fix

I banged my head on the wall a while but that's part of it I guess. You learn something new every day.
