help with a tuning questions

[nettles]

okay, I have a question... I am at the point of starting the 5.3 and I am trying my hand at the HP Tuners software. I turned vats off and it fired right up but running rich is an under statement. I am using a PSI harness and all sensors are there except the rear O2s. I turned them to no error reported in the DTCs but still idling really rich!!!! Is this normal at first? It has not been driven only sitting there at idle.

what injectors are you using? Are they aftermarket? If so do you have the right injector data? Are you running a MAF?

[nettles]

stock injectors, the whole thing is stock. And yes sir the MAF is there and plugged in!

what happens when you run open loop? does it still run rich?

[chvy=power]

and you have the right tune file in the pcm right?

[nettles]

and you have the right tune file in the pcm right?

I have not done that and yea its the stock file from the truck it all came from.

run it open loop and see what your o2 readings are

[nettles]

I will try this, and the dang O2 readings were actually in he green on the vc scanner if I remember right.

what did your fuel trims look like?

[nettles]

green also if I remember. Its in the teens here temp wise today so I wont be tinkering with is lol when I do I will let you know and also I noticed that the dang oil system does not want to prime. It is a 30k motor out of a total but it was drained of oil and stored for 8 months... I started it and it ran for a minute or so then I noticed the oil pressure never came up so I shut it off. I have to get oil pressure before I figure out the fuel I guess lol
