Finally I can run my LS3 consistently

I think you may still have some electrical gremlins.

Your MAP reading is interesting, there are a few times where it goes near or up to 100 kPa, but your APP is in the 60s. Can you see what part number is on your MAP sensor and let me know what that is?

Looking at frame 9900:
rpm 2501 spark 38
map 3.6 afr 13.878 wo 12.46
app 0%
mafsd 24g/s vss 0mph (how does that happen)

So is this crazy or what. This is similar in a few places like you said. As a newbie I have not idea where to start.
Of course I haven't got a handle on creating maps yet. One reason I do not know what to do with the data!
I appreciate you observations.

Yeah something weird is happening with your vehicle speed, it drops to 0 then jumps back up. Can you check your connections at the vehicle speed sensor and the engine computer?

The MAP sensor and the parameters for it in your tune are right, just wanted to double check.

Definitely need to figure out the speed thing first, if you're getting any bad signals to your ECU, you won't be able to get a solid tune on it.

I will but might be a few days. WE had a wind storm and something bounced off the roof n scratched a fender so it's back to paint.
I will go over the speed and pedal sensors when I get it back.
