This is only a momentary picture of the values. It is getting interesting if you do a logfile. I know it is difficult to export the logfile.But you can send it to your pc and import it in excel.Then you may diagnose it. More interesting is to open it in mems-rosco within readlog. But some values like gps_speed,v-maf,v-fuel,vtotal fuel and v-fuel will not be shown there.By the way, which value is unclear. (Tune-timing,tune-idlerpm and u-load is unclear for me too) But there is a forum for mems-diag too.

This is an example what you will see if you import the log-file in excel.
