Hi, got an 06 LBZ and run it with a DSP5 with Idaiho Rob tuning.
Have the EGR blocked and Deleted the heater grid with reporting blocked on both.
So now I have to smog it, never been an issue in the last 4 years until now. I make sure the codes if any are cleared, turn it to the stock tune and it has been fine.
Here in Cali they have a new PC I guess and it will not talk with my truck. Have been in 3 times now, passed visual but when plugged into the shops PC it will not talk to it. I watched and it states "aborted" while talking to CARB and shuts down.
All I can think of is 2 things. Unplug the DSP5 switch, it might be reading the extra wires going in/out. Then flash the stock tune back into it.
I did the grid delete about a year ago and turned off reporting, I may have to put it back in.
Any ideas??
