new to pfc and have a couple of questions.
i just got my pfc and am planning on getting datalogit when i learn more about tunning so i was wondering do i just need a wide band o2meter or do i need a sensor as well? also what air fuel ratio do you guys run and i know it might sound silly but what are the stock a/f #s. thanks for the help.

You need a sensor and meter all the good ones come with both ie... FJO,UEGO they run 750 - 1200$
The safer a/f numbers we shoot for are 11.1-11.5 range there is a thread titled "bring on the flames"THere is a section where I explain why these numbers. the stock ecu runs very very rich greater than 10:1 (the lower limit of most wide band units. the pfc with bolt ons just runs rich close to 10:1-11.1 depending on bolt ons.
enjoy

one more question.
do i need a wideband with just the commander or will it be okay with the stock one? if it helps i have dp, cb, cold air intake, non seq, and will be doing a mid pipe.
