alwas in closed loop

[supersport4]

Hey hows it goin..... i will attach my log file and tune when i get home, but i noticed that no matter what, im always in closed loop mode, and my stft and ltft always read 0 all the way across the board. I also see that my commanded afr is always readin 12.5. im pretty new to tuning, but i understand a lot of the concepts, and ive been and worked on cars for several years now. i have an 06 cobalt ss with a 2.8 pulley, 60s, intake, deleted cat with magnaflow exhaust, torque dampner, solid tranny mounts, and duall pass h/e with opt b kit. i also go into limp mode and get a p1182 code that i cant get rid of. plz help if you can

Looks like you are in open loop all the time, hence the 12.5:1 commanded afr the entire log and the 0'd trims.

no.....im actually always in closed loop. and my ltft reads 0 all the way across.... even when i go into PE mode it still shows im in CL....

[Bill@HPTuners]

Weird, has it always done this or did it just start?

[supersport4]

yes its always done it.. if you look in the log file and you press on the status bit display you will see when i go into pe and that even then it says im still in cl....... any suggestions??

[supersport4]

OK its been like a week and no 1 responds or gives any suggestions???

Have you been flashed with one of the GM stage flashes by any chance?

[Bill@HPTuners]

I did a little searching & it looks like this http://www.hptuners.com/forum/showpo...5&postcount=43 is your issue.
