Thank you for the concise and intelligent responses. My wiring was damaged/shorted under the dash.

I'm hardcore good on the wiring diag side of things. I just want to make sure that there is not a parameter of normally running a COS that will set this condition.

After that basic diag has been...

Before I go down the rabbit hole chasing this code.

Is P0650 a code set by running a COS3 setup?

I have always had the code set since I had the truck but I need to start setting up my truck...

Missed that FUBAR on B3618 big time!

I have made those adjustments as suggested. There are no runtime logs as it's the weekend and the truck is locked up at the school.

Take a look at B3647...

Here is my new updated tune and some longer logs. I'm gonna have to do something about my Trans fluid cooling. My Trans oil cooler is undersized but it was all I had sitting on the shelf here at...

JC,

I performed the A0012 and A0013 adjust and resave procedure as you recommended.

I upped C6101 and C6102 by 100% and now have BOOST! All I have to say is Gig-GAH-DEE!

I'll post logs...

I have been looking at other publicly posted COS3 tunes for a bit of research.

Tomorrow's trial by fire:

1st - I think I need to punch my C6101 & C6102 tables up a bunch and then come down...

Hi guys, I've been lurking on the forum since I first asked for help and I found several mechanical issues.
There were the wrong valve springs which caused a broken intake valve.

The kids and...

I have a nagging hunch that I need to check the valve springs on this motor. The dum-dums that had this truck before it got repoed took it for a loop in a parking lot doing donuts until the back...

This engine is speed density with a 2 bar map. COS3 - 12592618. I did a smoke leak check a while back with nothing found but I will spray some carb cleaner around the intake/throttle body to see if...

High guys. The kids and I have been working on the shop project for a bit and I finally have new hotside hardware installed with no leaks.
Previous running sessions were with the stock throttle...

What year gas pedal and tac module is installed? I had issues with a 2003 pcm talking to a 2006 tac module setting a p1518.

Hi guys,

I've fixed my P1518/P1514 issues from another thread but I want to start this thread for the sake of b9021.

I've searched this forum and read about the .cax files that are...

Success! Installing the matching 2003 gas ped and TAC module results in no REP mode and I now have smooth throttle operation.

Update: I just had that aha moment along with my tps glitch.
simply put... the tac module/app sensor has to match my PCM+operating system. A 2003 pcm/operating system is currently uploaded. The...

Hi guys, the insanity continues but this one really makes me go hmm....

I have what appears to be the OEM 4.8 throttle body; part # 1257080 currently installed. I watched my data while I...

I do have a new question and I might just pose it in a new thread for better exposure.
Since I have a 2003 COS3 tune installed, Do I need the older APP sensor (metal gas pedal sensor) installed?...

RAD,
You have to update your EFILive software to view the file. I just tried to edit for a bit at home with my not so up to date PC's EFILive and it gave me the incompatible glitch.

I've been playing with B3701 and B4001. So far i've noticed that I can't get my IPW below 3.5ms at idle which is leaving me stupid rich. I'm right now trying to get my head around what it would...

I dont know if I have a box checked or not to share this calibration correctly. Maybe the previous file name was too long.

Please try this one:

ok. let me see if i have a permission not turned on with my efilive. brb.

Is this the tune your asking for? Or is there a different format file? I included the data sheet I found on my currently installed injectors.
I've read that the 80lb/hr injectors are a tricky...

After some fresh gas and spark plugs.....

I got it to fire but it's pig rich.

Whats my best avenue of attack to whittle the idle map down?

Ok guys, I'm back after a hiatus of acquiring an V2 and getting the PCM unlocked. I'm going to attach my current tune but I know I have something going on with my ETC hardware. If you look at the...

The truck is a 2006 gen 3 4.8 1500 silverado.
It is converted to speed density and running on 80 lb/hr injectors.
Yes it has been tuned. By who, I have no fuggin' clue. - I'm thinking about...
