Does anyone know the address values for cylinders 1-6 on M-box to code out P0301 through P0306?
Running into a strange mis-fire upon warm restart which only occurs during the factory warmup cycle.

Why not disable misfire detection at idle speeds?

That's a good idea. What maps and values do you like to change? The problem goes away after two minutes, so I'm certain it's related to the warm-up cycle. It also doesn't seem to occur on pure cold start.

Got a wideband to check your warmup cycle fueling along with your STFTs?

Could be you just need some tweaks there.

I agree with nye. Likely you're just lean during warmup. This is a last resort sorta thing, but NMIALU, NMIDLU

I do have a wideband. What should I log to check these? I don't remember seeing a good way to fuse logging variables and wb-o2 output with synched time stamps. Are the typical maps used here: KFFWL_0_A + KFFWL_1_A?
