Hey there fellas!
So this is my first ever go at tuning fuel injection and I feel like I've done a fairly decent job at it. I do know there are still some tweaks I need to do in the tune and currently I am making tweaks to my timing and VE tables. I have my fuel trims disabled and open/closed loop disabled also, as I seem to be having an issue with my bank 2 O2 sensor, it swings up and down from the bottom of its range to the top of its range in a matter of seconds(over and over, nonstop) and it throws my afr/trims way off. Another issue I am aware of is my STIT is off in gear, which I haven't been able to fix by adding air to my BRAF. I gave up on that for the short term and will come back to it later as it starts and idles pretty damn good and doesn't have any cruise/hanging idle issues.
I am posting this in hopes that I can get some of the guys that actually do this stuff for a living (or the ones that are just dang good at this stuff!!) to look at this log and my tune and critique it. Tell me how I am doing, maybe what I am doing wrong, etc, etc. Criticism is definitely welcome! I am aware that my afr error histogram had some lean areas. I have already applied the changes to my tune, which is the tune that I am posting. I have been struggling a bit with getting my VE table/afr to remain stable from drive to drive. I make a change and it seems to do good, then I get in at a later time to drive it and it is almost like I did more revisions, except I didn't.
One thing that I am trying to get an answer to is why my bank 2 O2 sensor swings wildly like it does. I have done a ton of research and can't seem to find an answer. I am also having a bit of an issue with the car running lean right after I fire it up for a minute or 3, then once i hit the throttle or drive it a minute, it settles in and goes to where it should.
Like I said, I welcome any criticism, in fact, look forward to it!
Thanks everyone,
Anthony.
P.S. I live in the middle of Wyoming and do not have a very good selection of tuners to be able to take a peek at my tune, so I am, more or less, relying on your criticism to help me perfect this. Thanks again!
