I'm trying to accurately plot the Volumetric Efficiency (VE) of the nissan maxima engine, but i don't have a good logged run without turbo and the maths behind working out the VE requires air pressure / temperature to be static. (can be done with dynamic but requires temperature read outs and boost read outs for each RPM incriment. which i doubt is available).

What information i need:
can be from dyno prinout or any AF logged runs with RPM readouts.

engine size: (3lt or 3.5lt)
any intake / exhaust mods: (no turbo for previously mentioned reason)
Ambient temperature / humidity of dyno run: (state if its in Fahrenheit / Celsius)
injector size (stock a32 = 240cc, a33 and later = 290cc)
air fuel ratio readout @ rpm readout *** this is the main bit of information i need, without this i can't cacluate the VE.
Duty Cycle @ rpm readout *** also can't calculate anything without this bit of information.


what you get:
I'll give you your engines VE for each 1000 RPM increment until your red-line. This takes out a lot of the guess work for plotting on turbo maps. if you have a readout for bigger cams etc this will plot correctly on turbo maps instead of just "guessing". it will also help with working out fuel requirements.
