Title: location of misfire keyword codes on m-box Post by: s5fourdoor on July 29, 2015, 07:35:57 AM 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. Title: Re: location of misfire keyword codes on m-box Post by: ddillenger on July 29, 2015, 07:55:00 AM Why not disable misfire detection at idle speeds?
Title: Re: location of misfire keyword codes on m-box Post by: s5fourdoor on July 29, 2015, 12:19:16 PM 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.

Could be you just need some tweaks there. Title: Re: location of misfire keyword codes on m-box Post by: ddillenger on July 29, 2015, 04:25:25 PM I agree with nye. Likely you're just lean during warmup. This is a last resort sorta thing, but NMIALU, NMIDLU
Title: Re: location of misfire keyword codes on m-box Post by: s5fourdoor on July 30, 2015, 08:52:38 PM 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?
