If the STFT's/LTFT's weren't active, why are there values there? When I turned mine off, they registered 0%.

I honestly have no idea. Looking back at the data it looks like I was a little confused between SAE.SHRTFT1 and SAE.SHRTFT. They both say they are short term fuel trim for bank 1. The numbers are different, but only by 0.002 or something. Basically the same number. The numbers in the chart were from from the 02 parameter, not the Fuel parameter. The difference is insignificant.Originally Posted by SSpdDmon
Either way, I looked again. My long term trims were zero during the log. The short term trims still had values. Also, the long term trims that I put in those boxes were from a pervious log where I was in CLSD.
Can you look at my tune file to make sure I"m properly in open loop? I figured the short term trims were calculated but not used.
Closed loop temp enable should be maxed out. It's under one of the fueling folders. If that was done, you shouldn't have had STFTs. Hmmm....
I have that table set to 122 deg C (251 deg F). I definately never touch that temp. I have no idea.
did anything ever come of this?
\did you check b4108 which will return stft in OL or b4206? I've just been asking a question on whether stock os will work happily in semi-open loop mode by only running stft in CL
