That's not good either. It's a pain in the ass that it's there and you need to tune for it, or at the very least make sure you're rich when heat soaked as opposed to lean. Would hate for you to do a lean WOT run with a hot engine and knock knock. It's generally tuned at the end once everything else is locked away.
The MAF tuning should only take half a dozen good driving methods logs. If you're always adjusting fuel and then reflashing then adjusting again you'll get no where. Which is what you're finding out I'm picking from your recent findings.
Set up a filter on your graphs so injector tip temp >65 degC is ignored and combine that with ignoring throttle transients.
Here is an example of the filter I use, it is very conservative and only stable throttle gets through 98% of the time.
------------------------------------------------
Closed loop
ITT < 60 deg C [] ignore 0.5s either side of a shift [] smooth stable throttle [] ignore idle, coast, PE & DFCO
[6215.241]<60 and [2517.161.avg(500)]=0 and [2517.161.avg(-500)]=0 and (abs([50090.156.slope(1500)])+abs([50090.156.slope(-500)]))<2 and ([6310]=7 OR [6310]=9 OR [6310]=14 OR [6310]=15)=0
------------------------------------------------
------------------------------------------------
Open loop
ITT < 60 deg C [] ignore 0.5s either side of a shift [] smooth stable throttle [] throttle > 75% & in PE (ignores transition into & out of PE)
[6215.241]<60 and [2517.161.avg(500)]=0 and [2517.161.avg(-500)]=0 and (abs([50090.156.slope(1500)])+abs([50090.156.slope(-500)]))<2 and ([50030.91]>75 and [6310.avg(250)]=9)
