I have recently developed significant KR in the lower RPM ranges. It is more prevalent as you reduce engine speed towards idle and during low RPM’s. While accelerating or steady cruise everything seems fine. My tune is 2Bar OLSD, Further, look at my (4-29-09 1kr.hpl) scan, VE LTFT’s. I have my LTFT’s fuel trims switched off in my tune but now see readings in LTFT’s of -100's. The STFT’s still read 0’s as always. I made a 2nd scan (4-29-09 2kr.hpl) within a few minutes after the first and this time my LTFT’s read 0’s as normal. Problem is I never changed anything.
I have not changed anything lately and have no idea of what is going on with this erratic behavior. Can someone take a look at my scan? I also will include my latest tune.
