Truck is bone stock had a bullydog GT tuner on there that i wasnt impressed with, so i got a new tune and updated calibration via efi live. Truck woudlnt idle right after the flash so i was thinking it was the tune, reflashed the stock updated calibration on and still does same thing.
So did another full flash back to my original read i had, and still doing same thing, will not idle and when i do get it driving if i let off the gas it will idle at about 300-400 then just die

No engine lights, nothing else has been touched or changed besides doing a full flash

stock calibration i had saved is 12591723 with os 12592618
new one is 12591723 with OS 12606961
ive tried the new tune file, new stock file and old stock file none of them idle right and die when i come to a stop


drove the truck a while hoping it would maybe re learn, but no luck

 

ok after like 10-15 min of driving with the 12591723 file it seems to be running right

however i dont have a stock file, this read i have saved is with the bullydog tune on it, i want a bone stock file to work with.

anyone know where i can find a stock 12591723 file? I looked on efi lives website and in the directory of tunes on my computer that came with the efi live download but no luck

 

The Files are listed by there OS# not the calibration number.

The OS is 12592618
The calibration is 12591723

The first file I happened to pull up had exactly that combo. It was an 05 GMC L33 4x4

Also shows up under an 05 Silverado LQ4 4x4, 05 Silverado L81 4x4


What was your factory combination?

 

stock calibration i had saved is 12591723 with os 12592618

 

On tune file depot the Files are listed by there OS not the calibration number.

I opened 4 different combo's with that OS that had the correct calibration you were looking for.

 

yea i found the one on tune depot, got that saved to my computer.

I did get a updated tune with the new OS 12606961 which after a little bit of driving around and idle in park/gear it seems to be working ok. Guess had to adjust some idle parameters.

i looked up the new flash is the latest file for my truck via GM
