Don't use any of these files. This is me figuring out how to "HP tuners" with a moderate cam installed and not doing to well at it yet. Use the tune repository that's listed under your profile under...

HI Kevin87turbot -

I'll order up a new O2 sensor and put a fuel gauge in line. Thanks for the help with this. I was wondering if that O2 sensor was dead from what the VCM scanner was showing...

Did some MAF tuning ( about 4 pulls). it's still way out. If anything it's only got more rich which isn't bad. I can just adjust on the VE table. But the car still dies at a stop light, or if I coast...

Hi Kingtal0n - I too have read this. But my engine has a negative 3 degree angle on it, sloping from front to rear. I've checked as it's important for drive line angle set up. I also vacuumed the...

Hi 5FDP, Thanks for taking the time to reply. I thought I was logging MAP, guess I messed that up. As for the other info, I'll look into logging the airflow model both MAF and VE. Thanks for pointing...

I bent back to a stock tune and tried again. I've been learning some things and with others I'm not sure why it happens or how to correct it.

Fixed the Wideband not logging correctly.. ground,...

Hi Hotwire -

I too found that guide and gave it a shot. I didn't have my wideband installed initally, but my eyes were watering with the car outside idleing the car was so rich. Maybe now I'll...

Hi Hotwire, thanks for the reply! Ill take a look at your tune and see if I see similarities. I think I need work in the DFCO region really. But I don't know enough to say that for certain. I'll read...

HI All -

Just getting the car back together. I thought I had a blown head-gasket, but it ended up being one hell of an air pocket. Lesson learned, use a vacuum style coolant bleed / refill...

Got HP Tuners in on Friday.. Saturday after watching some videos and getting familiar with HP Tuners I was ready. I literally paid my near 200.00 to that shop for them to click abuse mode "disabled"...

Hmmm thanks for the info about the parts. Seems like I am stuck until I can pull data. I bit the bullet and purchased HP Tuners tonight and it should be here on Friday. So hopefully then I can pull...

I guess how do I know what year my stuff is then so i don't waste credits? I honestly can't believe that a vortec pedal from the same year group wouldn't work with another. One year only parts,...

The set up is drive by wire. New APP sensor, new app to TAC wire from PSI, and new (used) TAC module from PSI as well for a vortec truck.
...

Well this info made me dig a bit. I don't know why I've been saying Trailblazer for this long. Ok The 8th digit on the PCM was a "U" which shows as LQ4, the block is stamped with a "6.0" and is iron....

The engine, pcm, pedal, TAC, was a complete pull out from a 2006 trailblazer. The engine had no pedal response on first start, trouble shot it to be a bad TAC module. Purchased another for a vortec...

I could use some help. My g-body monte carlo is about finished up. 2006 Lq4 (engine and PCM), t-56, DBW set up, everything else is stock besides the transmission change, a Racetronics fuel pump and...
