Dumb question but if you do AFR> 14.6. This means that it will only record data that is greater than this value. Therefore due to tuning files you might have cells that actually run richer even without going into PE mode. But you will not catch this on your scanning because of the filter. Am I right.

unless your vehicle goes into open loop for some unknown reason it should ALWAYS command stoich which in most cars is between 14.63-14.68:1 UNTIL you go into pe mode...so the filter i posted will only show the data when the air fuel is between 14.6-14.79:1 basically.

Since we are talking about filters I can only assume you are not trying to avoid PE but filtering it out (recommended) I agrea with foff667 and tried to spell it out more clearly, [SENS.121] >14.6 Its simple and affective... Just add "Air Fuel Ratio Command Hi Res" To your table display. [SENS.121] >14.6 is going to filter out everything, Startup, restarts, PE until the Command ARF 14.681. If the Command AFR goes below 14.681 its filtered out.

thanks 1 slow, didnt think about startup...at startup your going to use your OLFA tables which will always be less then stoich...sometimes as rich as 9:1 commanded afr...just one more reason to use the 14.6 filter
