    I took a Techstream recording with 2 different cars, Prius Plus 2014 and Auris 2015, knowing they have same engine 2ZR FXE.
    I used same road, same driver, same speed and aprox same RPM.
    Here are the results.
    i wonder why the Auris have Evaporated Purge Flow less than Prius, and what means the negative value of Purge Density Learn Value?
    Please someone take a look and detail about differences?

    I would assume it's just the efficiency/efficacy of the EGR components versus wear and tear.

    The evap system and its purge arrangements are an altogether different system in the car from EGR.
