    Yes, Paul is adding that in for the next release.
    Acer, g*k/kpa I think is correct (I'll happily be made a fool of again), if you were in mg*k/kpa then yes were are out.

    With LS1s , I prefer to switch between g/s or g/cylinder (since it then can be setup to correlate with the timing tables). But i dont mind just changing a number by % errors collected in a chart.

    Ross,

    Double checked everything again & your "raw" numbers are of the correct magnitude if in g*k/kPa . The reason why I was used to seeing numbers 1000 greater within the ECMs table is that GM appear to be working in mg*K/kPa to calculate the injector pulse width from the VE table. Are you intentionally converting the GM table to revised units?

    Is the example of the table you provided (see link below) from a standard LS2 or a forced induction car as the values still seem on the high side?

    Have sent you another PM with adjusted factor to calculate the correct % VE.

    Cheers,

    Michael

    some newer research done on how to work with GMVE, what does it really mean, how to tune it, etc...

    LS2 airflow uncorked?

    yes and no. i have the formula to calculate it, but it returns very noisy signal. basically the temperature model goes out the window because the BIAS table needs to be adjusted, and there's no way i know of to really arrive at the correct numbers in them. you solve the bias table, and we can get the full thing easily. any takers? i hear it's some heat transfer engineering thingy...

    i got the BIAS formula from EFI's help files, 273.15+ECT+(ECT-IAT)*BIAS, but i cannot seem to match the scanned manifold temperature to the one calculated with the formula. what am i missing? where does the 'filter' value come into play?
