First post.
I'll start by saying I should be able to get some logs tonight or tomorrow evening, I meant to get some last night while doing some tuning/playing with settings but got a call from a friend needing something and forgot, so please be patient.

1996 NA8, 700cc Deastchwerks injectors, currently stock fuel pump, EGR delete, no name header, cheapo aluminum piping intake with a cone filter. GM IAT, MSPNP2 running tuner studio 3.1.08 and firmware version MS2/Extra 3.4.2 release 20160421. Need other info, please ask.

I recognize my VE table probably needs some work, please ignore all the "90" values in a group, this was just to give me a better point to adjust fuel from until I realized that likely is not my main issue, correct me if it looks good or bad in various places.
I've included my current tune, car was running really well until I started to play with the fuel VE table after putting in some Deastchwerks 700CC injectors, should have left it alone as I believe it scaled fine with required fuel being changed. The flow report for my injector set said 775cc, so I went with that number in my req fuel settings. Startup is pretty solid, cold or hot and AFRs are pretty minty at cruise.

I've done a small amount of offline adjustments that may or may not help. Might find out on my lunch break later and grab some logs for you all.
Sorry for being slow to the point. But, I have some lean and rich spikes, I know logs are important, but right off the bat, is there anything screwy in my VE or enrichment settings that set off alarms for you all?

Oh, so I don't seem dumb for the big injectors, or currently on stock fuel pump, I have the rest of my turbo stuff sitting and waiting to go on. I'm just trying to get everything sorted each step of the way, as the car is mostly being daily driven right now. So I'm taking individual step instead of doing it all at once, and trying to gain tuning knowledge/experience along the way so I don't break anything. I'll be asking more questions as the turbo build progresses, but right now.

Also, Innovate MTX-L wideband, that I have fought with the calibration on until it is almost spot on. A.K.A occasionally it's 0.1 off in fast changes between what shows on the gauge and what show in tunerstudio, but mostly dead on.

You should focus on getting your VE table looking smoother before you start worrying about stuff like EAE. It's likely the spikes are coming from some of the zig zaggy areas of the table, it might be helpful to take a look at the 3D view to get a better idea. If you just changed out the stock injectors to these new ones it's likely you just need some more time driving around letting autotune do its thing. Try to be smooth with the throttle and be sure to hit some of those cells between cruise and full throttle. You can slowly bump up the cell resistance as you go, and that should get the car driving pretty good. You can hand tune stuff like idle and tip in once the rest of the table is sorted.

I'm not an expert, and some of the more knowledgeable people around here might have better advice, but that's what I did to get my car driving good enough.

At risk of sounding even more noobish, that's what I did on the stock injectors, and it was smoother until I let autotune touch it again. So I have been working on that for the past week. Road tripped the car 2 hours one way and back and it did fine two weekends ago. Then new injectors and it feels like I've restarted, after letting autotune touch the VE table again instead of just hand tuning it.

I thought smoothing it out would likely be a go to.

When I upgraded from stock injectors my VE table needed some pretty big changes, so I'm pretty sure that's expected. New injectors change things like spray pattern, fuel atomization, etc. and that all effects your VE table. As you let autotune run, if you start to notice it's making things worse or the values are oscillating, change the cell change resistance from normal -> hard -> very hard. The key to letting autotune work right is having slow, deliberate throttle input. You can go back afterwards and smooth things if you notice weird areas that have large jumps, I see some areas in your table that go from 75 -> 70 -> 75 and typically you want to avoid large jumps like that.

Well, I used the high speed logger instead of the regular logger, because I started logging while driving. Any of my cruise/short periods of hard accel definitely look better.

But this is the results of my lunch break. Only a couple weird spikes, which once again, I'll get logs for you all, when I'm not in a rush to start the logging while keeping the car on the road.
I turned off EAE and AE before tuning the VE table. There is more work to be done, but it definitely feels better, especially with EAE and AE back on.

Haven't had a lot of time to review this datalog from yesterday evening yet, but here it is for you people that are smarter than me.
