Very new to all this, question

What is the difference between the "PRO" version and the "standard" version?

Besides price?

Pro feature set adds these features https://www.hptuners.com/product/pro-feature-for-mpvi2/

Got it, thank you.

Is it necessary to have the Pro features, just starting out like my self?

Will HPT read and log an innovate WB O2 sensor like the LM-2?
