its a 2019 camaro, it has a 416ci stroker 10:1 comp, tsp stage 2 cams with the big fuel lobe, LT4 supercharger and stock throttle.
The car starts very rich (black smoke visible on startup) and sometimes it will sound like misfiring, but after its hot fuel trims stay within +-%5 on idle, how do i fix this without skewing my VVE or MAF tables, and how do i get rid of the catalytic heating procedure on startup?

You need to post a log with a wideband. Your tuner should have taken care of the heat procedure - do a write entire with this one. Multiple tables play into the rest... You're still going to see rich/lean swings after startup from O2 test, but this should be better.
Thank you, i tuned it myself from stock to this point, having it idle consistently, on positive timing and not have it stall on decel has been a challenge, most of my questions had alredy been answered before so a quick search sufficed, but when searching for this one i had nothing.Quote:

Background tables. You have to do a write entire.
maybe you could point me to where i could learn about this?Quote:
