That's why I had to use the magic incantation to bring it back.

None yet, but will get one ASAP. How do you want me to post it? I don't think Photobucket allows posting of non-pic files.

BTW Thanks for offering to help.

 

Do yo have HPTuners or any tuning software?
If not send me the logs excel .csv

 

Yes, I have HPTuners, ver. 1.7. My .BIN file is here:

https://www.performancetrucks.net/fo...5&page=2&pp=10

if you want to take a look at it. I will get a log file as soon as I can.

 

OK I logged 2 runs (attached) both over the same route, holding everything as consistent as possible. The one named "cold-run" was done with the engine cold, and is when I have the trouble. "warm-run" is with the engine warm (running in closed loop) and everything is OK.

 

I was like whoa when did I start this thread?

I wish I could help you GMC DUDE but I can't remember what exact was changed but I don't have this problem anymore. It was something in the tuning though and I've changed engines again since this thread was made and I'm running a whole new tune.

 

Well I changed the idle airflow for in-gear to the following:

17.22 15.23 13.77 12.55 11.53 10.5 9.43 8.38 7.2 6.21 5.3 5.3 5.3 5 5.25 5.3

I saw one lean spike but that was it. Driveability seemed better but then again it didn't get very cold last night. This would probably be a better winter project.
