    Thanks, Shawn. I've got the CALC.VE pid selection in place and am looking forward to logging a run, working the tables, and checking the results. Hoping for some decent weather soon ...

    So is the displacement() function working for you/anyone...?

    Thanks guys.

    You can use the EFILive CALC.VE PID to get you close. If you can get that GM.DYNAIRTMP_DMA into your own CALC. PID, (as described) it dramatically increases the accuracy, especially in low airflow situations.

    As far as other platforms, 5.7Ute originally submitted the idea of including 'charge temperature' into the equation. He calculated it via look-up tables. So it may be possible to calculate the charge temperature for other platforms, but I am not sure. My laptop lagged a little with the look-up table scenario, but there is probably a way around it.

    As Joecar stated, I believe the new software update corrected the engine displacement problem that had existed before. Before you had to manually input engine size (or work around it). Should be no problem now. I'll try it out here in the next few days.

    I have an idea: replace {GM.DYNAIRTMP_DMA} with {GM.DYNAIRTMP_DMA.C}

    i.e. add .C on the end of it.

    Great idea!

    I will keep the editorial window open for technical revisions of this nature.

    What does this do Joe? Change it to metric units?

    Yes, it selects Metric units regardless of the default set under the PIDs tab.
