    why would table readings differ from chart readings?

    Hello i posted earlier and this was brought to my attention the map readings don''t match in the chart and table. i went and checked with the engine off and they differ by 50 kpa or so.

    usually when you have a custom pid setup referencing the map sensor and it skews the values.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    Bill I dont belive that there is a custom pid. I might be wrong as i downloaded this config from the repository. I will look this evening and see. Is that the only thing that would cause such? thank you for any insight.

    Yes that is the only thing. Custom pids aren't stored in files from the repository, they are stored in your VCM Scanner.cfg file in your hptuners-settings folder.
