EQ Commanded HELP 2018 Hemi 5.7L VVT

[importphd]

I'm new to the forums and started my tuning journey about 6 months ago. I am tuning my 2018 Ramm 1500 5.7L VVT Rebel. It has a custom intake, JBA shorties, and SOLO Performance Cat back exhaust, ADF E-85 conversion kit and FIC 525 injectors. I was feeling like I was finally getting a good grasp of tuning THEN I saw the trend of my commanded EQ Lambda at WOT. I'm seeing the commanded lambda at 0.928 at the start of a WOT pull, then after the shift it gets rich 0.674. My FA Stoich is stock 0.0720 and the FA PE table is set to .0056 across the table. From my understanding my truck should commanding ~.873 at WOT. What would cause the commanded EQ to be lean then swing so far the other direction?

Maybe something with the exhaust temperature protection FA Enrichment? Tables 44457, 34270, 34273

Add the Catalyst Temp and FA Enrichment channels to your logging and see what FA enrichment is being commanded and compare it to the cat temp to see if it aligns.

@stoopalini You nailed it! Looks like I'm running hot and the enrichment kicks in to save the Cat and O2 sensors. See the attached log. I'm going add more fuel in the PE Table and see if that helps. I'll post the results in the next reply.

I'd also check out your IAT wiring, as for some reason it's reading -83*F.

I double checked the wiring and reseated the sensor. It didn't make an improvement. BUT I had a thought and double checked the Channel. I removed the IAT and added the IAT (SAE) channel and now it is working. I appreciate you weighing in on this and helping me get better. You rock!
