Data logging wideband through ngc3's EGR position circuit

[06charger]

I have figured out how to data log my wideband through the egr position sensor circuit. I am just having trouble with creating a custom pid. (Sorry if my terminology is incorrect) i really have no clue how to make them to log a/f from the EGR position sensor circuit and creat an afr error % histogram. if anybody would be willing to throw some knowledge my direction I would greatly appreciate it.

Im using a 5 volt circuit and using 5 volt output from my wideband gauge

Let me know if I can give any other info that will help. Thanks
