Difference between disabled or enable LTFT and STFT?
Well guys i almost finish dialing the VE table on my 2004 5.3 and i want to leave it in speed density.
Right now i have the LTFT and the STFT disable, my VE is with 2% airfuel error at cruise and WOT.
I was searching around in here and looking at files and i see that some of the tunes have fail MAF, running in open loop disabling the LTFT but have the STFT enable. My question is what is the difference if i run open loop with LTFT and STFT disabled and running open loop with LTFT disabled and STFT enable?
Heres my file is a 2004 5.3 silverado with a 224/224 cam and headers with a 3200 converter.
I still need some smoothing on the VE table.
shouldnt matter. If you are truly in OL then the feed back from O2 shouldnt have any LTFT or STFT correction to IPW
Your VE table needs work. Have you run a scan that you are willing to share? Why are you running your truck in OL if I may ask?
