I downloaded your sheet, but I'm not sure what inputs are you using, can you elaborate further? please also upload the interpolation sheet, as I mentioned I want to be able to calculate VE through my data logs to be able to optimize AVCS advance.


do a search for the term "table interpolation" and select to post thread topics, and it should be the only one to come up

freon: that's pretty neat

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)
