look into Megalog Viewer (MLVHD) for log processing
create a custom field that converts calculated engine load to VE, if you want a real-time conversion
are you on Carberry SD or Merp SD?
I have spreadsheets that will take the VE table input and show you the output as BPW, IPW (final), g/rev, g/sec, etc.
SD multiplier (grams) * DISP (cc, L, etc.) = SD constant
In Carberry, the multiplier is fixed and the DISP is what directly changes the SD constant
I have changed my definition so that my SD multiplier is the same as Cobb's, so my 86F IAT centered VE table will match identically if I were to go to using ATR.
In Merp, the multiplier and displacement are both available.
SD constant * MAP = mass of air, grams per engine rotation
initial load calc * VE factor = calculated engine load for given cell
(2707.09 / injector scalar cc) * g/rev = base pulse width (BPW)
BPW * fueling factor (requested fueling, compensations, CL trims, etc.) = IPW (without latency)
and RPM/60 * mass of air per engine rotation = mass of air per second (or RPM/60 * g/rev = g/sec)
