ok I bought the basic interface and setup I had the idea that I could always buy the wideband but now that I looked into it I cant hook this guy to my interface so I really have to buy a whole need interface the mpvi and the wideband for it to work/be accuarate?
I have no idea what you drive but you can always log the wideband through the EGR wiring on a GEN 3 V8 computer in a truck/car.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
