yea I have, it doesn't do it on the stock tune. Thats what i'm thinking. Hopefully Nick can find a problem.

Here's about a 10 minute log of the truck going into "weird mode." for about the first 2 minutes the truck is normal and then it goes into this mode all of a sudden like someone flipped a switch....

nevermind I figured it out. Of course now that I start logging it won't go into "weird mode." I'll have to wait until tomorrow morning to get it to do it.

And no this wasnt a script. It was my original tune that Nick just modified for me. And I doubt its limp mode because it will go into this weird mode even if i'm driving like a grandma.

So which pid's should I select when I log the ecm?

Okay thats what I thought. Then that rules out the transmission itself or tcm tune being the problem. That is correct, I am getting no codes and I have scanned multiple times for codes and I don't...

I didn't say I just uploaded the stock engine tune. I said I uploaded the stock tranny tune. 2 different things. And having gone back to the stock tranny tune, and the problem still remaining, I'm...

So does that mean the problem is with the tune?

Great. I just uploaded the stock tcm tune and it didn't change anything. It's still going into "weird mode."

No I told him from the beginning that I had a suncoast kit already in the tranny even though I didnt because I didn't think it would cause any problems. I'm going to try to put the stock tcm tune...

No I really don't think its the fuel filter because 1. I changed it about 600 miles ago and 2. it is very unlikely that it would have gone into this "weird mode" because of the fuel filter when it...

Thank you for your response and yes you are correct about the cold part. It seems to do it on the first start up after the truck has been sitting for enough time to get the engine and or transmission...

I recently upgraded my 06 lbz from a bullydog powerpup hand held programmer to a dsp5 switch with 5 tunes from nick@duramaxtuner. I told him i wanted a stock tune, tow tune, smoke tune, mid hp tune,...

Okay well I forgot to mention that when I was pushing one of the pins in it broke, so I cut it off and just used a pin from an o2 sensor off of my 2000 1500 truck and as the idiot that I am, I...

Okay thank you I will try to reseat the pins and report back

So the other day I installed a dsp5 switch on my 06 lbz. I followed the efi live dsp install pdf. and did everything it said. I have the latest version of firmware, took my stock tune and converted...

No unfortunately it is not working on vmware fusion. I am having trouble with it recognizing the device in the usb port for some reason I think there is something wrong with my laptop. I had to use...

Wow thank you so much everyone I finally got it to work. For a second I thought I had been sold a broken unit! Thank you especially joecar, I followed your attachment and it completely fixed the...

Oh this all makes sense now then. No I have not stored any old files for 2 years. I just bought this new and unopened EFI live v2 flash scan from a guy in Carolina who bought it a couple years ago...

After countless tries of attempting to read the tcm and ecm stock tune on my 06 LBZ, I kept getting the same result saying that efi cannot recgonize the tcm or the ecm and ultimately says calibration...
