Yeah pretty much... I sent the log to your email. Cant upload it on here

 

you would not have this problem with hp- tuners:

lol
j/k

i still have the SME-DVD1/SME-DVD2 on calibrated success , it covers all this information , 2nd dvd is 85% EFI live..

 

Yea, looks like the test for catalyst effectiveness, or something like that.

 

I dont even have cats or rear O2s. I guess I can look and make sure all that stuff is turned off....

 

My truck goes 16:1 down to 13:1 and back to 14.68. its an emission test that I cant tune out. Or thats the best explanation I have for it. all my cat stuff is turned off, and there is no other tables to tune.

 

Mine does it too, I have watched it do it on the wideband, but truck doesnt miss or anything when it does it so I have just let it be...

 

Well that just sucks.. It sure is annoying

 

Put the rear o2's back in it will stop this...in fact i'm 99% sure you only need to plug them back in and wire tie them away...dont actually have to put bungs in...spent 2 wks chasing this on my 06 after header install, you absolutley cannot get around this in the tune.

 

If you haven't already try disabling B0804 (Catalytic Converter Protection Enable). Possibly even poke around Fuel\Cat Protection

 

I found a thread on the efilive forum about this exact subject and it is a emissions setting that oxagenates the cats. Its a setting/function thats built in the PCM that cant be tuned out on older PCMs. On the E38 like mine theres a parameter that can be adjusted to turn it off but i havent confirmed that yet.
