Well post up an efi log if you have one. I have efi but use HPT, but should be able to see something obvious. Any DTCs? Don't have a rag in the header do you?

 

LS1B_0128.efiI will try and post a log as soon as I can.
No dtcs except for the normal ones I had before for other stuff and the ones due to the truck not having a trans in it right now, got a fresh trans with new billet goodies and a fresh converter from circle d waiting to go in but no time due to this stupid problem. Lol
Headers are coming off to make sure I don't have any leaks, timing cover is also gonna come off to check the dots, new cam sensor, ect sensor and map sensor are things I am gonna try( I have well known spares), also gonna grab a different computer.
Good thing it's winter and I don't drive it in winter but being lifted it truly is a pain to work on, milk crates and sitting in the engine bay are common for me. Hahaha

 

that log doesn't really have the best pid list. I have a better one with misfires and stuff but forgot to log with it. I mostly watch real time right now. I will see if I can get a better log tomorrow

 

Can you log with B4205 maxed out....with wideband logging?

edit typo: should be B4205 not 06

 

I really want to thank Drx for all the help he has given me with this thing. he has been going above and beyond helping me try and get this thing figured out. between txt messages and emailing back and forth since Friday night things are starting to look good for me
I have 2 more tunes from him to try today.

 

So is it looking like a tune issue or a mechanical issue?

 

I just got in from logging and with fuel taken out it runs ALOT better.
my af gauge shows it running right but the logs show its running lean.
runs like the af is correct tho.
Drx has been a huge help and even sending me links to the cable I need to hook my lc1 up to my v2.
I am new to this tuning stuff but he has taught me so much in a short period of time.
its running way way better then when I first made this post

 

Trimming was out of control and could not even be disabled due to a corrupted OS. Can now start to sort out the rest.

 

Well that's weird...

 

little update. tried another tune from dr.x with the stft enabled and some fuel pulled and the truck ran a lot better today. the trims looked way better and plugs looked good.
I finally was able to do something other then try and fix this stupid problem so I got my trans back in along with some other odds and ends.
cant thank him enough for the help and also thank you atomic for giving some suggestions aswell. really appreciate it
