He also, references the PHR articles.
As a second thought:
get an old MAF, and matching ecm, hack the diagnostics, so that it doesn'
use any default values, and hook a diacom to it.  Instant accurate
gram/second flow rates.
Then if your real good you could set the MAP filtering rates.
Since your just doing one port the "smaller" the better (ie jus an old 4
cylinder).
Makes me want to build one now, well maybe after I finish the ecm bench LOL.
