I logged one more time after posting, Now this is what happening, Strange!!!!
The first one the Main VE table started out around 1.07 and averaged out around 1.01 to .98
The top pic is after copy & past ,but after copy & past, it made the second pic go rich

one goes good them after pasting it goes rich ,back and forth, can not get it to do the same two logs twice in a row

On the last log ( second pic.) it started out rich .90s and leveled out some what fair.

This pic here is the one you say I'm ready ,looks grate


#14 log is loaded in 0002 tune
#16 log is loaded in 0003 tune
This pic here is the last one i done ,nothing change in the tune but it went rich for some reason ,But i can install ether one .

I'm not able to view your logs right now, but I would speculate changes in the ambient temps are providing a bit of the tail chasing you are seeing. This is where the IAT VE scalar comes into play.

On your other question, yes, it's normal to see your average values change as you collect more data for each cell. Typically the extreme high and low values you see are due to transient conditions.

While you are logging your data, it's very important that you control your right foot to avoid causing excessive transients.

Well i believe Ive got it all done ,can you look at my log and see what you think, The only thing I'm have trouble with now is I'm having a miss or stumble in the upper rpm range around 6400 to 6600 rpms. I have a wot run at (frame 8439)

A0011 and A0012 are out of range... set them to 511.

WOT is good.

PT is not as close... STFT's average about -9% during PT, but that's ok, you're letting the STFT's do the trimming.

Good job.

You may also want to log the following:
- DYNAIR (gives an idea of airflow rate),
- DYNCYLAIR_DMA (used to index into HO/LO spark tables),

[RandyWS6]

do you meen A0012 & A0013 ,the A0011 is valet mode or two step it wont let me put numbers in there

[RandyWS6]

I dont have the pin56 installed yet for the valet mode
