DFCO is enabled no matter what your injectors want to do... If you decel it works fine. Also I have ran 60s on pump gas for years and years without any "rich on decel" conditions without modifying anything.

You can use TT to adjust min pulse width,
Minimum pulsewidth is a bit misleading... Its not minimum commanded, but it is actually your "minimum deadtime"... aka minimum injector voltage offset. The voltage offset table works with that table to determine minimum pulsewidths. There are some quirky tables that actually delegate what your minimums are when your pcm wants to violate that rule... and its not pretty.

So I was doing a few scans and noticed the LtFTs moving.
2 things.

1. for some reason the LTFT's will read crap randomly during warmup, cat testing (select 00+ files only), maf fail mode, among other things. I have never found them during normal driving, but it will show up alot during idle for me every now and then. It doesnt seem to effect anything.

2. The PCM seems to be very good at randomly remembering fuel trims from when it had closed loop. you have to clear them out a few times using the fuel trim clear command in DHP to lose all the ones in the fuel trim table.
