Why is my AFR so noisy?

It seems an earlier quote by Innovate could ring true. I've read on the Innovate forum about the LM-programmer not storing settings when they are changed from their default values. The advice there was to update to the latest firmware. (which is located on the splash page when you boot up).

Looks like you rescaled the table a little. What size are your injectors?
A little rich at and coming off idle will ride nicely. Lean spots will surge or buck. The fuel economy penalty for running a tad rich at light load will be very small.
It also looks like you allow autotune to affect changes in the idle area. I prefer to tune idle by hand and then restrict the autotune to not make changes in light load by setting up the filter on the VE analyze dialog box.

The auto tune feature is the slang term for VE Analyzer in megalogviewer, which obviously works for you.
Try cleaning off the headphone plug serial connectors. I used a little bit of rubbing alcohol, and it helped clear up some communications issues I was having. Then when you connect them, snap them firmly and spin all the way around. Make sure that contact is solid.

I waited until 1 a.m. so I can get this nice piece of road for myself. Went outside to start car, took 3 tries to start it and the battery died also from cranking. Realized that I tighten my CAS bolt a while ago, so I decided to check my timing in case. Couldn't get a signal from plug #1, but plug#2 and #3 were fine. Opened up the plugs and plug#1 had gas on it, while the others were lean (just as my AFR said). No spark on plug#1 also when placed on valve cover. Swapped to my extra coils and still same result -_-.
Horrible luck! I'm ordering some spark wires, these spark plugs have less than 100 miles on them!

I don't mean to hijack this thread, but I've been getting some serious fluctuations from my LCII wideband also. Can't seem to tune with it ... that's no surprise given this output, right?
I've doublechecked my ground ... anything else that might be going on here?
Thx...

Yeah, that map is kind of a disaster, after tuning against that messy O2 signal.
I went out and re-checked all the ground wires just now ... turns out there WAS a ground problem. I fixed it and the signal looks a lot better now. Going to start over and retune. Weird thing now is that above 3500 or so in higher gears I'm running really rich (<10 AFM).

I have both grounds from the LC II soldered to a lug, and I attached the lug with a new nut on an existing screw at the rear passenger side of the engine. Other wires are grounded at this point, and I believe this is where the ECU is grounded as well. I hadn't tightened the bolt very well, and so the lug was a little loose. After tightening it down my signal cleaned right up.

Here, I found the link where I read it:
