Default more hot weather tuning woes

my ms is pulling way too much fuel above 105*F intake air temps. below that the afr's seems to be dead on. ive even tried ramping up the iat correction like crazy b ut its not helping. im noticing around 8-10% lower duty cycle when its hot but cant seem to get it back up.

here's my datalog and tune please help

sorry. MS1v3.0 firmware 029y3

/\ that doesn't look that good...IMO it should taper down to operating temps and let the map take over, not spike up.

I'm tipsy though so I'll look at it again later lol

I'm not certain what MS you are running, Fastiva, but MAT corrections didn't do **** for me untill I nerfed the GAIR setting down to 50%. It still basically wtfoverrode my MAT corrections untill then.

ms1v3.0 there is no gair correction to change

my cells were in the 250's so i raised my req fuel, rescaled my fuel map and started over from scratch. i noticed while tuning the afr gauge and digital readout in tuner studio was dropping into the mid 10's but on the data log it show'd the lowest afr was 12.0. are the data logs that far off or is the gauge in ts thats wrong im stuck and frustrated.
