GM stage 2 tune and LTFT log -45 to -50, what gives?

[redhotjamedjimi]

wheres the log and tune sir.

[Nmbr1GMfan]

didn't save the log and its a GM stage 2 tune

[redhotjamedjimi]

my guess would be that the trims arent a problem. i have idle trims of -20. as long as u arent loggin any knock or other problems let it do what it wants.

Sorry Im busy and can't seem to find time for the computer. Wouldn't VE adjustments bring the trims back in check?

[redhotjamedjimi]

rather run a lil rich then lean in my book. was it in Sd or Maf.

Are you still runing the stage II injectors or did you put 60's in?

True. MAF.

Stage II

My first guess is you are using the LTFT sensor and it's factoring LTFT for Bank 1 and Bank 2, since we have a 1 bank engine you need to only use Bank 1 LTFT for your scanning...

I am almost positive it's a scanning config problem not your engine/calibration.. Remove any reference to bank2 in your list of scan'd PID's

Try using this VCM scanner config.

^ Yes what Zinner says. The default config basically should be junked and redone if you are using a Cobalt, since the default is based on 8 cylinders (I think it's a LS1 config anyway.) These cars use just 1 o2 sensor for the LTFT and STFT so only one bank. Same with Injectors there is only 1 sensor I believe. Good luck

Here is my config also
