Finally got the car stable at idle and now it's the smoothest it's ever been but i do have some questions just in general with tuning

Anyways I finally got to take the car out for a light cruise. I didn't try and kill it just enough to get it up to speed and get a good log to see where I'm at, going through the log however i did notice some knock about 6 degrees at some points and 2-2.5 at others now I have seen where some people say this isn't a lot and I'm not exactly pulling my hair out over it but I would like to minimize that as much as possible and get an explanation of what's going on I've searched the forums and I have seen where people say pull timing or add full etc. but I'm unsure which would help

However, like I said I'm fairly new to tuning and don't know everything I'm looking for so if you guys see something you don't like somewhere else and ill work on that as well!

Looking very quickly:

You're like 2 full points lean.
Your TPS adjustments are insane.
1400 target idle?
SD table is wrong, load in a 'stock' table.
Looking at the TPS adjustments I only messed with the TPS offset using the adjustment suggested at by ECMLink. As to why the TPS scale is 199, I have no idea any idea, what it should be at?
My car idles smoothly around 1200-1300 anything under that and it will stall out I've tried everything under the moon to lower it and read plenty of threads on it nothing helps

And I am tuning on SD the car came with a MAF-T and we decided to go a different route

Why is your SDTempWeighting map zero'd out?
I myself haven't touched that tab maybe the guy I bought the car from zeroed but thank you I wouldn't have even known that was wrong
 
When you switched to SD did you put in a IAT sensor? I don't see it and it's acting locked.
The idle vacuum readings seem really low even for those cams. That would have a big impact on idle speed.
IAT sensor is next on the to do list the sensor already came in the mail. i saw that you need it for speed density but didn't have it when I made the switch will be installing soon
 
Have you made sure base timing is 5* BTDC? It hadn't been mentioned.
