I run Autotap real time data option this morning and it expresses short term fuel trim (STFT) as a percentage rather than a change in voltage as is discussed in some EFI articles and/or blogs.
What I saw was Bank 2 (drivers side on a Ford) the STFT was swinging further in each direction zero % to a greater degree than Bank 1 was.
What is your opinion of what this is indicative of?
Thanks
