tts barometric setting

[jpbo]

Good day
i need some help with brometric setting, first i followed the tuning for dummies, no mention for baro setting, bike run great. Reading the tts tuning guide i saw i skipped the need for barometric setting first, so i think i have to start a new tuning .Reading tts tuning i'm confused with setting baro at first. is someone can explain to me how collect datas and make corrections in table?
any help will be appreciated
thank you
